Yes, Mobil 1's first oil was a 5w20.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.quote:

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.
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.quote:
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.
If this guy knew much of anything, would he be working at WallyMart?quote:
