Originally posted by HOndaGuy: if amsoil didn't change their formula to group 3, then i probably would have used it. Isn't it true that mobil 1 came out with 20 wts when they first came out? Anyways, i can't wait to see this oil on the shelves of walmart.
quote:Ted, where do you get the HTHS for the M1 0w-20? It's not published, and if you ask Mobil 1 for the spec they will tell you the minimum spec required for the SAE 20-weight designation--which just happens to be 2.6cP.
Originally posted by TooSlick: Honda Guy, The HT/HS of the Mobil 1, 0w-20 is 2.6 Cp, vs 2.9 Cp for the Amsoil 5w-20. So I would content that the Amsoil product is actually a bit thicker in the bearings of an engine.
quote:I agree, my car went through the 0w-30 very quickly. IMO, this is not a good oil unless you have a new engine. It's just not shear stable enough.
I'm interested in Mobil 1's 0w-20 is because it may offer the gas mileage and shear-stability benefits of M1 0w-30 without the volatility problems of that grade.
