How does Royal Purple HPS 10w-30 compare to Amsoil? Amazon pricing on RP is considerably less than Amsoil.
I use 30 weight Rotella Diesel oil with my 331 stroker. It has a large amount of detergent in it which keeps the internal parts clean. Everytime you go for a re-build you can notice who uses the detergent oil because the parts will be relatively clean compared to conventional oil.
It's what most engine builders recommend.
