What do you think for a Chevy 350 V8 4 bolt main with about 400 hp. Cam, high compression, ect., no smog, 7 qt pan, in a 43 Willy's. Should I use 10w 40 Mobil 1 or the 15w 40 Shell Rotella (has the anti-wear additives still in it)? Just thought I would ask, I am interested in the responses.

Rotella is designed for diesel engines. Use the Mobil 1.

If those were my only two options, I would choose Mobil 1... Why? Because Amsoil makes the additive package for the Mobil 1, so most of its protecting/cleaning factors are attributed to Amsoil. However, if available, I would just simply get and use Amsoil, it blows the rest away.

mobil 1 10W40 is thinner than 15W40 the w stands for winter in that equation so it will start easier on cool summer mornings when you want to........
just go for a ride

10W40. It will get flowing faster in the cold and get in the tighter spaces better.
