Annoying dealers? Never experienced that.

Despite many of their annoying dealers, they make top notch oil. The oxidation readings for Amsoil are in the 50-65 range. So they're using substantial V.

The dealers ain’t too bad. It’s the guys that use Amsoil in everything, tell everyone else to do the same and won’t even entertain the thought that there might be something more suitable for a certain application. Don’t get me wrong, I use some Amsoil but their true believer fan base is a little nuts at times.

Not if you seen the results like I’ve had. Even at that I don’t use it in everything anymore. If I drove the miles I used to I would go extended and use it. My Avalanche transmission and 373 limited slip rear end has it. The newer vehicles I would research to see if it’s compatible. As far as dealers I’ve seen signs in parts stores that sell it. In my travels I’ve seen garages advertised it for oil change service. People are passionate about lots of things. Being passionate about Amsoil isn’t nuts. I believe oils aren’t as far apart in quality as they use to be. For the average driver oil changes are more important than the name brand synthetic they use. If I was working in the extreme like I used to then Amsoil would be my choice.

I was talking to a guy who swears Amsoil in his transmission stopped the slip yoke on the driveshaft from binding and thumping. The slip yoke is bolted to a flange on the back of the transfer case so that’s not even possible. Next thing you know he’ll say Amsoil helped him regrow his hair and lose 20 pounds too. Passion is great, but the fanatical brand loyalty crap loses me.

Had to do it.

I think it's almost always aimed at Amsoil's pamphlet regurgitation association. Despite the MLM, their products are truly excellent. We have some of the best blenders in the world IMO. Amsoil, HPL, Red Line, Torco. All USA based.

Amsoil is using a good dose of some exotic group V too.

I invite all to read the sample blends on page 9. Note the viscosities of the various oils. Note the notes. Pretty low.

Then scroll down to page 23 and read the heading FILM STENGTH. Let is set on the gray cells awhile. Then compare to what we have talked about concerning Stribeck. Consider that the discussion on film strength is the very definition of Stribeck.

Now go to page 21 and read EHL and take note of film thickness, asperity height and the discussion on what is happening to the metal.

Scroll down to page 36 and read the box "Lubricating Regimes". And again, same page Lubewear. Notes on particle size and 'abnormal' wear".

Okay, got all that? Good. VISCOSITY is PRIMARY.

Go to NITRATION. Read OXIDATION. Read FUEL DILUTION. Note the comments on OIL CHANGES when faced with dilution. It's worse with gas than with diesel fuel.

Ask yourself if anything you've read in this article is anything different than what I've expounded to death?

How do you suppose a SAE 40 is made if no VM is used? By using a base in the 100C viscosity range to begin with!

Now, and finally, I pound on Ester bearing oils not just for solvency but for REDUCTION OF VM's required. Sometimes NONE and if none they do not deplete and if they don't deplete there is no viscosity loss due to shear, only dilution. 5W20, 10W30 and 15W40 CAN be made without VM's. Note that even 5W30 using current base tech only uses 3% so a PAO/POE needs next to nothing. It's a barbell blend.

@MaverickZ71 THANK YOU.

Stole this from Bobistheoilguy.

Amsoil subjected to the Kurth Orbahn shear stability test. Excellent results after 90 cycles. Viscosity loss of only 2.6% after 90 cycles.

......but WHY?

Because the second you start the motor oil starts to change and that change is never for the better.

When I started this post, I had an idea that quickly evaporated as I started pulling my thoughts together. There is no consensus even among the most educated and most experienced. None! But they all will fight to the death to be right. Right down to Joe Average.

31 pages of thread and what do we AGREE on. That a driveline has a finite life. That oil has a finite life. Agreement stops there.

There is just too much information NOISE, information ENTORPY (yea, look that up), for facts to be heard or seen clearly. Too many willing to get as close to the edge as possible and as it seems with enough personal wealth to not really care if they fall over it a few times during their lives. "I don't care" can trump a fact fast enough to drown it before it takes a breath.

Below is part of a study showing the random nature of elemental results over time. [Quote]

Lubricants | Free Full-Text | Prediction of RUL of Lubricating Oil Based on Information Entropy and SVM (mdpi.com)

As can be seen from Figure 5, with the change of time, wear metal elements mostly show an upward trend, additive elements mostly show a downward trend, and the changing trend of comprehensive elements is uncertain. [end quote]

Information ENTROPY. This entire study was to find a method to filter that noise to a high probability. Think about that the next time your lab says 1 ppm of X element is crossing the line and he knows what is causing it.

FYI, as of last week, select Walmart stores are now carrying the new Valvoline Restore & Protect motor oil in stock (formerly was shipping only) at the reduced price of $29.97 for a 5-quart jug and $10.77 each for individual quarts.

Valvoline states that this oil uses a specific new additive technology. It's not done through the use of esters like their Premium Restore Cummins product. They also said that anything the oil comes in contact with it will clean. My thinking this oil could theoretically clean intake valves. I called them this morning. Who knows this could be a sleeper.

See the photos of the Toyota and borescope images in the reviews below. Not sure if it's real or not. Appears to be.

If it gets to the valves it sounds like it could. If you mean as a spray or short residence time use it might or it might not depending on the chemistry. If has a heat activated synthetic chemistry that mimics more expensive esterified stuff it may be too slow on cold intake cleaning etc.

I made no sense. Brain bag is defective unless I go slow.
