 Time to switch oil?So when I got my engine rebuilt, the engine builder recommended VR1 10w-50 Racing Oil because of the zinc content. I have since changed the cam from a flat tappet to a roller cam with a roller lifter kit.
So should I change to standard motor oil now? I've got about 5000 miles on the engine since the rebuild. What should I be using? For what it's worth, I've been using the Baldwin filters. _________________ 69 Wagon, 351W, Explorer EFI & Serpentine, ZF5, 35" tires, 3.5 SL, 2 BL, WARN 8274 |

Re: Time to switch oil? I'd stick with an oil with a high zinc content. It can't hurt. My machine shop recommended Rotella T after I have used up all my racing oil.
The alternative is to use an additive. BG MOA for instance. _________________ 1973 Bronco, 351 SEFI, Locked, discs, 35's ZF-5spd and Atlas 4spd. 235:1 Crawl Ratio. It may be ugly, but it's slow. http://www.ucora.org |

Re: Time to switch oil? Rotella changed their formula and cut back on the zinc a lot. I used to run just regular Valvoline. Now I run Amsoil ZRod oil. Flat tappet or not high zinc is good to have.

Re: Time to switch oil? Right or wrong I'm running plain ole Valvoline 5W-30 with a 1994 block and roller cam.

Re: Time to switch oil? I run 10w -40 Lucas Hot Rod and classic oil. High zinc content only reason not to use high zinc oil is if you have a catalictic convertor. Shell has changed formula on Rotella less zinc .
