Response to Re: what kind of oil should I use in my 390 FE |
| If it has a flat tappet cam, one must use a high ZDDP content oil like the Shell Rotella oil mentioned in a post above. Although I am not familiar with Royal Purple's current blends, if it has a ZDDP level of 850-1,000 ppm+, I'd use it. That or a high ZDDP oil along with G.M.'s E.O.S. supplement.
If your running a roller cam (hydro or solid) pretty much any old oil will work fine!
