It's to me, really starting to sound like Amsoil thinks it knows better than those who design and build engines. And have been doing it for far longer than Amsoil has even exsisted.

And that just isn't so. synlube acts the same way.

See, this is why I won't use non approved oils. Any oil can claim anything they want. But unless they submit to the auto maker's testing and prove it, that's all it is. A claim.

When it comes to my car, I am the court that you appear before. And the court is not interested in what you think/know/claim, but what you can prove.

And unless you are on the mfg approval list, then you haven't proved anything, and your case is dismissed.
If the manufacture requires you to be on their "approved" list, then I would agree with you. But they don't.

Mobil 1 5w30 is on many manufacturers "approved" lists, but was shown by Valvoline and Ashland that it didn't even pass basic API tests for engine wear. No thanks.

There are motor oils that are API certified, that didn't pass API certification tests when API tested them off the shelf. No thanks.

I'd rather use something that has been proven to be much better by undisputed independent ASTM testing and backed by a much better warranty for much longer oil change intervals. More time and money saved, and better for the environment.

So I guess we will have to agree to disagree.
