With the temps rising and my pressure dropping a little I want to upgrade to 10w40

 

Amsoil premium sythetic 10w40 for sure.

 

castrol syntec 10w40

 

Royal Purple 10w40

 

royal purple... u serious? i hope u stop using that man,


motul 300v

 

I always thought it was better than mobile 1 and Castrol syntec?

 

supposed to be garbage when combined with turbos, apparantly it gets caked up with the extreme heat.

I went with Amsoil 10w-40 as well

 

Mobil 1 10w40

 

ok amsoil it is unless i can fin m1 thanks guys! BTW not to go there with another oil battle but have any of you seen this new Castrol Edge? Seems to be a lot of hype over it. They don't have a 10w40 yet, but maybe when they get one i'd try it out.

 

the only m1 i see in a 10w40 is the truck one or the 5000, what do you use?
