This Amsoil series is awesome. Thank you for spending the time to go through the details.
Thank you! Cheers! Stay tuned for more, we got a new episode coming next week.
I was an AMSOL dealer in Maine for 30 years. Now a Amsoil preferred customer and retired living in Florida. Finally get to see behind the scenes of there factory and lab. Thank You Gale and Amsoil.
My '88 GTA Trans AM still has the Banks cat-back system that was installed in the late 80's / early 90's. My father was part owner of an emissions lab in Anaheim. He was quite impressed with the Gale Banks organization. Don't know if he ever met Mr. Banks, but my father was a huge fan of the organization.
I was introduced to Amsoil by a friend back in September of 1973. I kept using it in all my gas vehicles and when I started using Diesel trucks to haul my RV’s I enjoyed a continued great service life. Not one of my cars or trucks ever used oil in my extended mileage traveling. Oil analysis at almost every change always came back ‘oil still serviceable’. I changed oil at 7 to 18 thousand miles, depending on the type of driving I was doing. On a drive to Alaska (Arctic circle) from Buffalo in 1999
This series kicks ass. No bs just straight science. I love it and thanks for doing it. Also it shows how much of a genius Banks is.
Im loving the dive into motor oil knowledge. I have used Amsoil for years, and my real world experience lines up directly with their claims. Two great American companies!
Thanks for watching, we love hearing from our fans! Stay tuned for more, we got a new episode coming next week.
not slamming on Amsoil, but i used it for a while long ago in my '98 cherokee, and was changing well within on time, and easy miles/hwy. And it once became thickened like i've never seen before in any car situatino ever. Very disapointed in Amsoil quality control-- that was around '06
So Amsoil admitted using a Group 3 base stock. Is this for all diesel oils????
@@candyman1967 they use different base stocks in their three different levels of oil. So, the answer to your question is no. They mention the different base stocks they use in them.
@@stusvids3595 I never saw that mentioned. Only that they use group 3. Where can I find the info for Signature series diesel 5-40?
At 63, I now understand what my chemistry teacher was trying to teach me in HS. Chemistry made simple, in layman’s terms. I had to watch it twice though. Simply, an awesome education.
Thanks for watching, we love hearing from our fans! Stay tuned for more, we got a new episode coming next week.
I had a high school chemistry teacher that hated chemistry. Her idea of teaching was to read out of the textbook or to have us read out of the textbook. I think she was put in that position by an administrator as a punishment. I was able to drop out of that class.
22:58 Thank you Gale! Had some coworkers who bought into the stupid rolling coal image. In addition to what you're saying here about soot getting into the oil, they also couldn't comprehend that the black smoke from their diesels is actually unburned fuel, meaning their precious engines weren't actually running correctly, while also dumping expensive diesel straight out the exhaust.
Another great video with great information. I switched to amsoil about 5 years ago and have been really satisfied with their products!
What a great video. Banks is here asking all the questions I am wondering myself. Thank you for such a great video, Gale.
This is fascinating! Thanks for working with AMSOIL to show us all this information.
Thanks so much for this series! It’s at the right level of detail for my interest.
Awesome video and can't wait for more. I had a 94 ram 2500 with the 5.9 12v. I did some work to it to increase power. I have to throw this out there. I used the banks twin ram intake. Massive improvement on how the truck performed. And also at that time I didn't have knowledge of synthetic oils. I used Mobile 15w40 diesel oil in that truck and in my 99 7.3 f250. In both of those trucks I noticed the slobber tube always was steaming away. More so in the ram. Come time to change the oil at the 3k their was considerably less drained out than I put in. The oil just vaporized. Since then I quit using the Mobil diesel oil and moved to Amsoil OE diesel oil when I bought the Nissan titan diesel. Don't have that truck anymore but I use Amsoil in every thing I have. Trucks, tractor , mower, my echo equipment.
This is the most useful episode by far! Thank you Mr. Banks for your efforts.
Glad you think so! Thanks for watching, we love hearing from our fans! Stay tuned for more, we got a new episode coming next week.
It is nice he is explaining things at a middle school level so more people will understand it. Thanks for the education.
This is absolutely fantastic content. Thank you so much for this video series! I have always wanted to know this stuff.
*Thank you Gale and AMSOIL for making this excellent, informative video.*
Our pleasure! Stay tuned for more, we got a new episode coming next week.
The Amsoil PR team has done a wonderful job taking us through the creation of their product.
Gale is just a wealth of information and he clearly knows a lot of this information. I quickly Googled his name for a detail to send to a friend along with this video and was shocked to see he is 79! He does not seem like he is nearly an octogenarian. If there is anyone with more knowledge on diesel on this planet I would be shocked, Rudolf Diesel would probably be shocked at where Gale has taken this engine type.
Wow I would have never guessed his age.
This is hands down the best "what's in motor oil" video series out of any of the other guys who have done it
Wow, I will never look at engine oil the same way again. Thank you AMSOIL team and Gale for the education.
Thanks for watching, we love hearing that folks are learning with this series! Stay tuned for more, we got a new episode coming next week.
As one manufacturer says...oils ain't oils.
I love these educational videos. Thanks, Mr Banks. 👍🏻👍🏻
I love these episodes! I never was interested in science. It wasn't brought to me as a practical application. This keeps me interested. Thank you Gale Banks!
Great to hear! It's awesome when fans are learning. Stay tuned for more, we got a new episode coming next week.
Love this series so far, was able to identify most of the chemical reactions and their ability to react for most of what was presented and enjoyed the Aha moments.
This is awesome information. It clears up a lot of misinformation about synthetic and conventional oils. I have seen first hand the performance difference in running a conventional oil vs a synthetic oil in my vehicle. When I run synthetic oil in it the engine is a lot more responsive and accelerates noticeably quicker than when I had conventional grade oil in it.
Awesome organic chemistry review. I got a B in organic chemistry at university 35 years ago. Very interesting chemistry of motor oil. Thanks guys!
That was so very informative. Thank you, Banks & Amsoil teams!
Love to hear this. Thanks for watching. Stay tuned for more.
Thank you for doing this & posting. I wish there was more educational material like this available done by people who know what they're talking about. So much that's out there is either marketing nonsense or from people who don't really know what they're talking about.
I like the series! Uncle Tony's Garage is doing something similar, he's explaining fuel economy and fuel combustion in older classic engines. School is in.
"Professor Banks" ... what a joyful ride into this subject. Retired (40 years) Lockheed Martin Engineer here ... knew a lot, learned MUCH MORE with this in-depth look at lubricants ... and just how important it is to pay attention to the OEM Engineers "Vision" on interaction of metals and oils. Growing up as a kid and "Dad" religiously following the "warm up" (every start) now makes sense given 50% of wear is at the beginning of start up ... there was no "Film" on the bearing/cylinder walls and a "metal to metal" contact point. Key points I enjoyed ... the eddy formation if you don't use the correct viscosity oil and "moisture barriers" ... the latter I can't tell you how much "raw material" I've had Subcontractors scrap when I caught them with "Surface Corrosion" on sheet/plate stock ... "intergranular corrosion" is real and over the "Life Cycle" of metal components, must be stopped up front. And just an FYI: "Between 9,000 and 12,000 metres (30,000 and 40,000 feet), the cruising altitude of most jet aircraft, air temperatures range from −40 to −70 °F (−40 to −57 °C).". And as you made a side note on "Diesel Fuel Waxing" ... learned the trick of that over here in the French/Swiss Alps in a rented Diesel Motorhome ... a bit of "gasoline" will get you home ... LOL. If you're ever in the French Riviera on Vaca, do let me know ... I think we could have some fun conversations over a Coffee !!!
This is why modern oil so well-made today even within the last 10 years I would say our technology and knowledge base it’s awesome!
I love all of Banks Power's video series, however, THIS is the kind of content I subscribed for!
😁🤘🏻
I had a basic understanding of oils but this video gave me a lot more info about the chemistry and all the technical terms. Never tried Amsoil but I know it is absolute top notch. I usually help my dad put Rotella 5w40 diesel oil or Valvoline 5w40 Premium Blue in his 2020 6.7 Powerstroke. I bought a gallon of Motorcraft 10w30 diesel oil to use in all of my small engine power equipment because of the 1000 ppm zinc levels.
i have never enjoyed nerding out so much! this series is awesome!
Thanks for watching, we love hearing from the nerds! Stay tuned for more, we got a new episode coming next week.
I’m loving these episodes! I only use Amsoil in my vehicles and lawn equipment and I’m more resolved in my choice to stick with the best!
Me, too! I'm thrilled with how well it works!
I’m a recent convert to Amsoil and it’s a choice il never regret. Excellent stuff much better than other brands and I mean MUCH BETTER. All engines are smoother, which is the biggest change after changing and the fuel economy is slightly better but different engines vary.
I still have a hard time feeling ok with running a motor oil long term like they claim can be done. If I only put 10k miles on my truck every year, I'd be fine with that, but last year I drove over 110k miles and this oil gets pretty spendy
@@goodmanboattransport3441 If you combine AmsOil engine oil with their bypass filtration, you can do regular, oil analyses and keep your oil in service for a very long time! I have around 10,000 miles on my oil, and the truck still runs silky smooth! I'm trying to get it to a yearly oil change. So far, it seems to be working great!
@@goodmanboattransport3441 well, if you spred oil cost over miles instead of an engine replacement or rebuilt, I would guess its not that expensive at all.
Mr Banks is a Legend. His knowledge and personality makes for a truly remarkable individual. Every piece of content I watch in him makes me want to be better at my trade.
Another great episode. Thank you. This is even better than the differential cover series!
Thanks for watching, we love hearing from our fans! Stay tuned for more, we got a new episode coming next week.
Great video Gale!...a lot of great information in these videos and nothing better than coming from my favorite lubrication company!
Our pleasure! Stay tuned for more, we got a new episode coming next week.
This is absolutely the best info on oil I've seen in 20 years.
Wow, thank you! Thanks for watching, we love hearing from our fans! Stay tuned for more, we got a new episode coming next week.
This is some AMAZING information! Thank you for bringing us this info!
Good episode. I do wish they would've covered the other additives like friction modifiers, extreme pressure, anti-foaming / anti-aeration, and viscosity index improvers. I could see it being too much to pack into one episode though. The differences, in structure and performance, between star polymers and OCPs is good stuff, as well as performance aspects of group V base oils like polyol and adipate ester, trimethylolpropane, and alkylated naphthalene.
this dudes science break downs are epic is amazing how simply breaking down exactly what's taking place and why instantly makes understanding what's taking place under the hood so much easier... it's crazy how long the engine has been around yet since the carb has gone the way side its just thought that engines are to technical so people simply rather stay ignorant then just try to learn
huge props to amsoil for doing this, I love it!!
Great display & explanation of this complex subject. One question I didn’t hear asked, however, Gale asked a lot of great questions. What is the process for using a synthetic after a rebuild or new engine? Is it essentially to use a “break in oil” for a set amount of time then use a conventional oil then use synthetic? Thanks again for making this visit to Amsoil. Very good to bring up the SOOT & use of additional additives in an already remarkable product.
Keep the videos coming I love learning from Banks :)
Will do! Tune next week for a new episode on Motor oil chemical lab testing.
Amazing explanation !!!kudos to both of you 🎉
This is really great well broken down and high level
A very, very good and informative presentation. 👍
Great series! I had a Banks Turbo Tube header on my 2nd Grand Cherokee 4.0. Been shopping Banks products ever since 👍🏼
Thanks Dan, great explanation! !
Well done!! I appreciate all the info packed in here! 👍😎
Glad to hear it! Thanks for watching, we love hearing from our fans! Stay tuned for more, we got a new episode coming next week.
28:40 is the best thing I've heard in a video about engines in a long time. Companies full of awesome employees spend tons of time optimizing materials and oils to make it work the best. It's amazing people think they can outsmart the millions/billions of dollars of research when working on their own engines.
Yeah! And I'm sure they wouldn't spend money trying to convince us otherwise!
You mean like the first gen Dodge take a 325 horsepower Cummins over a 5year period , pare it down to 160 so that the 30 yr old torque flight 727 could survive it. Your telling me there's nothing left on the table beyond 160 if you solve the week Link in the chain of failure. ( Yes you would just keep moving down the line to the next weak link. Till you have 1000fttq monster of a 2020 raped in 1991 clothes.) Allison will hold .
God Damn it Uncle Gale. You throw so much knowledge at me at one time I have to watch your videos at least two or three times.
This is an excellent explanation of intricate chemistry. Glad that both of them dove into it enthusiastically and without apology for enjoying the molecular details. Amsoil's process looks similar to that of a blender of fine Scotch whiskey.
Glad you enjoyed it!
I cant wait for the next segment!!!!
If there was a Banks school I would go to it. I have learned so much about specific and detailed information on diesels than I ever would have thought. I’m sold on Banks and Amsoil for life. And coming from an aviation background this leaves so much to be desired in my field.
I am guessing that the curriculum of that school would be heavy on marketing.
Wow, what an amazing and informative video! Congratulations Banks and Amsoil!
Thank you, glad you enjoyed it! Make sure you check out these other videos. Ep3 👉🏻 kzhead.info/sun/gdmRYdiPrn6grHA/bejne.html Ep4 👉🏻 kzhead.info/sun/oNKslamce4WMd4U/bejne.html
@@bankspowero Mobile one synthetic is no where near as. Good as amsoil am I hearing they correctly
An impressive operation to be sure…. Wow…..very nice 👍
School indeed. Great info, thank you 👍🙂
My father, who was a professional mechanical engineer, taught me that it is good practice to put an engine to bed hot. Getting the oil hot helps condensation (moisture) evaporate from the crankcase. That said, it drives me crazy when people will occasionally start a (long term stored) vehicle for a short period thinking its goid for it.
Great video Gail thank you, my theory is when you jump to a thicker oil you also create more heat in the bearings because my theory is reducing your flow your resistance to flow therefore your flow is reduced through the bearing and that flows not able to dissipate heat as rapidly!
This is an incredible series and definitively answers questions I had years ago where I actually called several motor oil companies and was unable to get a definitive answer. I'd like to know what oil change interval Dan Peterson uses in his cars.
Thanks Gale what a wonderful Video Thanks Again
This video series is very well-balanced between scientific technobabble (which 99% of viewers wouldn't understand) and comprehensive physics/chemistry for the layman. And since Amsoil allocated manpower and time, it's perfectly fine for them to promote their own products. And their products are top-notch, so it's not plain marketing mumbo-jumbo.
This was so informative, thank you
Great explanatio. Reminded me a chemist class
Yippee. Was waiting all day for this!!
Very educational and informative, thank you very much
Ya this series is great!
Thanks Gale good deep dive.
Forty two minutes on synthetic motor oil chemistry? Yes please!
🤓🔬🧪
Very interesting. Oil oxidation causes engine sludge, 38:54. Lots of good information here and worth watching. Of course this does not show which chemicals fully make up synthetic oil, trade secrets. Thanks for sharing
Very educational with awesome folks in the industry
🤘🏻😁
I love how much banks hates rolling coal haha.. I wish everyone with a diesel would listen to him.
I mean he’s definitely not a subhuman so…
@@Polyalp ya I just don't get how the most known tuner in diesel screams about it constantly but yet it's basically a signature of diesel..I dunno, sucks
@@forbiddenera I mean man, anyone who has any common sense would realize that rolling coal is a bad thing. Fuck them.
@@Polyalp you'd hope so but so many people are like "diesel has to be super rich to make power hence the smoke"
@@forbiddenera I do understand the dilemma, but rolling coal is way beyond a effective ratio. Anyway, great video.
Thank you for making this video ..
Thank YOU Gale !!
Our pleasure! Thanks for watching.
For the 5 years my 1ZZ-FE (Corolla) engine was under warranty I used Amsoil Signature Series but followed shorter drain intervals to maintain my warranty. I am now in year 12 of once-a-year oil changes with Amsoil Signature Series 0W30 and EA Long life oil filters. The engine is running as smoothly as the day it left the factory. I have saved a fortune in oil change expenses and generated far less waste oil than I would have done with conventional or lower grade synthetic oil.
I have a 1ZZ- FE also! Bought the car brand new on Saturday Jan 1st '05 with 000,037 miles on it. On Wednesday the '5th it got Mobil 1. I still have it with a lil over 670,000 miles on it! Yep 670! How do I know it has 670??...cuz after 299,999 the odometers stop going any higher. After that I keep track on my trip meter in a notepad. My oil change intervals are ALWAYS between 22‐2700 miles. I did discard using the factory oil filter and put a much larger filter on since day 1 ! PN 1516WIX..twice the pleating surface area.
@@vannorman1116 If the odometer has six digits it's a million mile odometer. It shouldn't stop at 300,000, it goes to 1,000,000, Well actually 999,999. It's broken! ok?
Watching this after finishing organic chemistry gives me such a better understanding
Love the effort in the video & the explanation. 37:19 The data appears incomplete as the time (hours) is not given. So we do not know if this is after the normal suggested change interval. Engine oil blending was part of my interest years ago. But a big Thankyou to Mr Banks & teams for presenting this video.
In regards to the hours, this is a lab test AMSOIL uses to improve motor oil formulations that run in severe conditions in the field. The test length represented in the graph is in hours. Both competitors' useful life ended after day 10 or 240 hours. The AMSOIL Signature Series product had end of life happen after day 13 or 312 hours.
Brilliant, just waiting the next one.
Tune in next Tuesday, more is on the way!
This video gave me so much more respect for my oils.
Wow! This was some great information. 👍😎
Glad you enjoyed it, thanks for watching.
I have met and spoke to the two engineers at GM who plotted the oil change graft. Short trips, oil temp, coolant, long trips and even calculated engine loads. They pointed out the was based on recommended synthetic oil values as recognized by ASTM and they can't control what brand of synthetic is used, only how it reacts in the engine under a huge number of factors. Concluding they kept it on the conservative side to attempt to get the best results of least wear to testing for metals known in the engine, but the oil itself. Not all synthetics are created equal as some use cheaper additives to reduce POS and maintain a market share. One admitted he bought one the last GM "F" body's and used Amsoil in his vehicle. The other had no comment but admitted he changed his oil more frequently instead of waiting for 10% oil life, changed his at 30% oil life. ACDelco MASM, retired ASE master tech.
Very Informative informative! Much appreciated.
Thanks for watching!
I apologize if this has been covered previously. I just recently purchased a 2021 392 Dodge Challenger Scat Pack 392 T/A. Oil recommended is Pennzoil SRT 0W40. In April or May 2022, 60 days 6000 miles, it's due to be changed to keep it under warranty. It may have 200 to 300 miles on it then. I live in northern Indiana near Notre Dame, so it will probably stay garaged the vast majority of the time. So, the question is, stay with Pennzoil or go with Amsoil 0W40 Signature Series? Not a question of money, rather protection and possibly performance. Maybe too soon to switch? Need 500 miles, I believe, to break in engine. What should I expect by switching brands? Love your videos, great detail and educational. Happy Birthday Gale on your birthday coming up soon!
I had a ford 7.3 diesel years ago. I ran 15w40 year around. Didn't realize the top end wasn't getting oil during winter start up. Wore the valve guides and cam bearings out.
I've been running Mobil 1 for years. I might switch over to amsoil for a couple of my vehicles
Very educational! Hopefully the “rolling coal” folks pay attention! I remember Gale saying long ago that soot is horsepower you’re leaving on the table
“If you roll coal, that’s horsepower going out the exhaust pipe
And I, doubt that The coal rollers pay attention, they Long ago flunked out of their ability to so do. And they fell for The Flat back rear diff covers are more better!
What he said about deleted the truck makes no sense tho because the egr is putting your exhaust back through the motor exposing your motor to even more soot, even a stock truck makes soot the dpf filter just catches it so it’s still getting some soot in your oil no matter what.
"anyting you see coming out of the tailpipe is lost power" Gale Banks
@@offroadcanadian807 I think that is more down to Auto Manufacturers making inefficient intakes and manifolds for diesel engines instead of controlling fuel flow
Im old, so I loved my dinosaur juice. loved my 20/50 motor oil. You just showed me the light, I'm switching to synthetic oil and proper oil viscosity , although I still go up a little on high mileage cars, like from 5w30 to 10w30. I was driving an s10 chevy that had a slight rod knock for weeks, called for 5w30. so to get home I changed the oil and put 20w50 in it. drove a mile and the rod came through the block.
Pretty good text book stuff. LIke to see the oil hit the metal.
Very educational!
This is a really good video
Awesome video!
The explanation of oil viscosity does explain parasitic power losses & rotating shafts, but it doesn't mention sliding surfaces… Piston ring to cylinder wall surface is the largest in an engine, add in valve to guides and those are responsible for any/all oil consumption (+turbochargers). A rotating shaft also has a journal surrounding the shaft, except valves/tappets/rockers sliding on camshafts.
How many hours of a test on the oils for that graph? I feel like it was conveniently left out. Great tidbits of information that the layman could understand surrounded by physicist speak! Thanks Gale! Looking forward to the next video!
I wondered the same thing. It looks like the test runs way out to failure. While a typical oil interval might be 200-500 hours, I wonder if this is 1k-2k hours.
The scale on those graphs is generally misleading. Engine oil failure tests generally aren't run in real world conditions, because they would take way too long. To get them done in a reasonable amount of time, the oil companies usually do stress testing - so they'll run the test at higher temperatures, reduce the oil volume to make it work harder, etc. Once you've done that, the test hours bear no resemblance to real world performance so they just show the relative performance between the oils.
This is a lab test AMSOIL uses to improve motor oil formulations that run in severe conditions in the field. The test length represented in the graph is in hours. Both competitors' useful life ended after day 10 or 240 hours. The AMSOIL Signature Series product had end of life happen after day 13 or 312 hours.
@@bankspower Thanks for the info! It would have been useful to have had that on the graph itself. God bless and Merry Christmas!
@@bankspower it would be cool to see the log(hours) time scale. Betting it would make the curves piecewise-linear...
A little information is a wonderful thing. When I started riding Harleys in the 70s, everyone ran 60wt in the summer and 50wt in the winter. Sometimes even 70wt if it was a hot summer and ya had to sit in traffic a lot. But it made cold starting a pain! When multi-grades started catching on, I started running 20W-50, everyone said I'd ruin my motor in no time.
Good video, I worked in an oil plant and worked in the hydroprocessing unit. Was good to see process involved after the synthetic crude left our plant. You made a mistake on Sulfur, its removed for environmental reasons but its actually desirable in a diesel.
Sulfur is NOT desirable in any engine. The process of removing it removes lubrication properties,
As a Q(uantum)Chemist and a serious gear-head, I love thinking about this stuff. I can hands down say this is the best video on the subject on youtube. Well done! "This does not come out of the ground!" Well said! For anybody curious, too much (S)ulfur would basically screw-up any important reaction with catalysts and really just broadly anything not related to sulfur chemistry at the temperatures required for manufacturing lubricants. Not to mention consumers can't seem to stand the smell!
Very nice explanations with a lot of info. Take away for me is, just change your oil at the OEM recommended intervals using the recommended OEM viscosity oils, and you'll be OK.
My take away here is I got ripped off paying double to triple price of conventional oil for "FULL" synthetic oil product that was made with conventional oil. Now I know why my engine and transmission would wear out by or before 200,000 miles. I will never buy another bottle of a lying ass "FULL" synthetic. Amsoil for me because I know what I'm getting from here on out.
very interesting. I take from this that if I use castol synthetic in my ordinary gas engine and change it early enough. I should see little or no difference. but don't push things performance wise or oil change schedule.
I was hoping to see a conventional oil plotted against those synthetic examples in the final graph.
Many years ago I did a comparison of used conventional oil versus used synthetic (Mobil One) as I was curious about the heat threshold of both oils. I put both oils in separate metal containers, heated them up with a torch flame on the bottom sides of the containers, and noticed that when both got critically hot, the conventional oil was boiling and emitting smoke, while the synthetic boiled without smoke. Keeping up the heat, the conventional oil ignited with a dirty flame; while the synthetic kept boiling. After another 30 seconds of applied heat, the synthetic did ignite, but its flame was nearly as clean as kerosene. After that test, I was a confirmed believer and user of synthetic oil for internal combustion engines.
@@bloqk16 I suppose if you engine gets hot enough for the oil to boil, and you keep driving, it's worth it...
@@Cheepchipsable in high performance Diesel typical failure mode is the aluminum getting soft(~1200°f) and allowing the rings to move out of place I'd say that's hot enough to boil oils especially when you have a continuous stream of oil spraying the bottom side of the Piston to keep it cool and it still melts. Also with this failure mode it is typically witnessed heavy coking on the bottom side of the piston from the oil Boiling off and leaving the solids behind.
High heat resistance is super important for turbo engines. The turbo shaft gets stupid hot and actually burns the oil badly, and can even coke up if it heats up too much.
I'm curious about the lack of units for time in the last graph. At what point does the oil start to oxidize and sludge up? It's not clear
