[QUOTE="Cobra'03, post: 516248, member: 3013"] Mobil's 0w20 is on the low side of viscosity specs for this grade class - which is too low to begin with in my opinion. I previously posted on why Ford recommends 5w20, and why they say "the engine is not designed for it". One is a flat out lie, the other takes a perspective that does not look out for the owner, but for the Green party. A 5w20 usually specs in the 8.6/48.0 centistokes range for low and hi temp viscosity. Mobil 0w20 specs at 8.4/43.0 - that is five points lower in the high temp range. There is little margin of safety in a high temp, high stress enigne like ours. I prefer vis closer to 60 cST in the 100degC range - that is closer to a 30wt spec - which is why i use Amsoil 0w30. I would prefer to use Pennzoil 5w30 or 10w30 over any 0w20. I want to see the long term engineering studies in real-world before I expose my engine to sewing machine oils. [/QUOTE]
