When I ran Amsoil I used 0-30 exclusively, both SHOs
What I'm running now is a custom 7.5w-35
I did not switch due to any real or perceived issues with Amsoil.
We shall see how the oil analysis bears out.
If it was my car in a cold climate I'd run 0-30 Signature.moem1090 said:FoMoCoSHO said:SHOdded said:Panther is the only other person I know of considering 5w40. Should not use above 5w30, I think, or you could end up jamming the phasers and possibly the turbo oil feed lines.

Think I should switch grades?

ZSHO said:Amsoil is certainly a great oil indeed and that cannot be disputed,but using a different grade than specified on the owners manuel or oil cap can ultimately have a negative effect on the cam phasers and lifters especially if a thicker oil is being used. Z
Wouldnt dirty oil being changed in longer intervals play a role.ajpturbo said:ZSHO said:Amsoil is certainly a great oil indeed and that cannot be disputed,but using a different grade than specified on the owners manuel or oil cap can ultimately have a negative effect on the cam phasers and lifters especially if a thicker oil is being used.

Not if you are running the car so hard that the oil thins causing the oil pressure to drop.....the mfg is anticipating normal operation in which case they can properly recommend the viscosity....
You have to first understand what happens to viscosity when temperatures change.....the mfg recommended viscosity may become a problem if you are operating the car in extreme conditions
