    the engine I have is a 1973 351w. Someone was telling me to use Rotella diesel oil. I was wondering what you guys use and what weight. What oil additives do you guys use to get the zinc? looking forward to responses.

    The Rotella no longer has enough zinc to sustain life of a flat tappet cam. I prefer the Joe Gibbs Hot Rod Oil (now known as "Driven Oil") or the Valvoline VR1. The weight varies according to many variables.

    Do you use vr1. 20w-50 just seems like such a heavy weight

    Rotella doesn't have much zinc anymore? Then that has to be for any of the diesel oils. So I'll keep Valvo VR1 in mind.

    Yes, they took out a sizeable amount of additives when diesels started to need to use cats, I believe it was in late 2011.

    I like Castrol edge 5w 50 with a shot of Lucas Zinc additive. My 'chero seems to love that combo once a year.

    Schaeffer's semi synthetic or full synthetic, generally I run 10 / 30 weight but if I anticipate some severe duty I go with 10 / 50. Got plenty zinc and phosphorus for older engines and have yet to degrade a converter. I run it in all my engines from the lawn mowers up to the big diesels. I love that Schaeffer's will do a free analysis on any sample I send to them, wear metal analysis. Even the sample pee-bottles ship free.

    What weight oil do you guys use. I've been told anywhere from 10-30 to 20-50. I want to use something a little thicker than usual

    Depends on where you live. If you live in the cold, snowy northern areas I would stick with the 10w-30. 20w-50 might be a little heavy. I run the 20w-50 in my 57 & 38 Fords along with my 79 Ranchero but I live in Az. where it doesn't get too cold.

    Clearances have a lot to do with oil viscosity - but most people don't have the ability to check them. So the easiest way to check is to try a lighter grade of oil, say 10W30, and check your oil pressure after it's HOT, if it's acceptable then stay with what you have, if the pressure is too low at idle then try a heavier oil such as 20W50 and compare results.
