Back to the viscosity and the question of whether the manufacturers vary visc. for CAFE numbers. Yesterday I saw the owners manual for a 2002 Chevy Blazer for export. Recommends 15w40 or 20w50 oils in all engines. Anyone have a book for the U.S.?

I think that is a given. Trucks fall under a different (or non-existant???) CAFE. Hmmmmm... the same engine in a truck calls for a higher viscosity than the same engine in a car.... Hmmmm what could this mean??? Mayber an oil heavier than 30 wt is good?? [Eek!]

Trucks do indeed come under CAFE. They have a lower figure to meet. I think it is 22.5, or close to that. A bill was voted down, that would have combined cars and trucks at the 27 car level.

I didn't check the book to see which engines are offered. Should have. It was a customer's Blazer, so if I am in the office 4,000 miles from now I will ask to see the book again. Maybe he will be in for a wash before that.

Blazer would be the old 190 hp 4.3L V6 Trailblazer would be the all alloy, 270hp 4.2L I6. Both are available for 2002.

[Off Topic!] Is'nt that 4.2L having major issues? Also, I hear it uses a panel filter. Maybe someone can confirm this [I dont know]
