Reply to "Engine Oil Testing Results"

Lots of confusing technical info in this motor oil thread. I am getting my '72 Pre-L back on the road after a long sleep. Fluid changes are the first order of business. My 351C engine is bone stock with 40k on the clock and it's never been opened.

Is there a concensus for a recommended mineral (not synthetic or semi-synthetic) oil for 100% street use? Also what is the recommended viscosity and what is the current thinking on adding a ZDDP additive? I've used Valvoline 10W40 in the past, but can't recall if it was VR1.

Thanks very much.
