I heard that AMS oil is 100% synthetic whereas Mobil 1 is not (full synthetic). Motul also has 100% synthetic engine oil. I have been using Mobil 1. Wondering if I should switch to AMS? I suspect that this would clean the engine better than full synthetic? Is AMS oil available at Autozone or pla…

OK by not request here is Scottie. @asemaster [The Best Engine Oil in the World and Why You Don’t Need it]

I could have gone the rest of the weekend without seeing that video.

I think I appreciate him more than you. It is sunday by the way :wink:

[image] sciconf: Why oil pressure drops : one culprit is gunk build up. Not for a racer. Extremely hot oil gets real thin. It flows easily past bearings which often have larger clearances than street car bearings. A winning race engine strikes a delicate balance, on the edge of destruction. …

Apparently youtubes by ‘randos’ are more to be believed.

I reject your source.

I am an automotive engineer, racer, DIY mechanic, engine builder and I understand how oil systems work. And I don’t work for Amsoil nor any other oil companies…
