Hi, I have a question about the JR supercharger setup on a d16y8 (Civic ex) engine:
I'm currently using Mobil-1 10W-30 engine oil. Is this grade ok, or should I switch to the 15W-50 instead?
I have the high output fuel pump and the boost upgrade kit (shows about 8.5 psi boost). I was wondering whether this 10W-30 oil is too thin for a boosted engine. Thanks for any help
