Such a stud oil I thought I'd post the pic again for those that ain't seen it
xxxDOHC VTECxxx ,
Don't be shy about asking questions .
One man's race oil is another mans junk .
I will not let too much info out here for a few reasons but..... as the engine gets larger IE cubic inch and the resultant larger crank pin , heavier rod , heavier piston usually depics larger clearances . Then and only then do you see these 40wt oils ran unless the engine is built for extremely high RPM and is a smaller engine .
It's funny when I hear a builder quoted as saying " I use this oil up to X HP , above that I use this oil "
Where you live there are a number of oils to take you back and forth from the track , to and from work ect w/o draining for a pretty long period .
If you want to use Redline , use the 5w-30 in that motor . Call Dave and he will say yep to the 5w-30 too
There is a relative large number of oils that would work for you and the Mobil , Redline , 76 Synthetic , Valvoline 5w-30 Race and the new Lucas Xw-30wt are but a few .
