Oil suggestions ...

I use 10-30 dyno oil with a 1/2 bottle of GM EOS and 1/2 bottle of STP after break in.Tom

Driven, Brad Penn (or Penngrade) is all good stuff, I don't think you could go wrong with any of those choices. The green stuff is popular.

I use Amsoil Z-rod myself as it's easily available to me.

It's all comparable stuff.

I use Valvoline VR1 10w30 & a Wix 1st line oil filter. The VR1 is high in ZDDP....Joe

I've used Brad Penn and Joe Gibb's Hot Rod Driven in the past but now use Valvoline VR1 10w-30 conventional oil, not the full synthetic that I've heard is available now. It's cheaper than the other two and my local auto parts store carries it, but not Penn or Driven.

I also use the Valvoline VR1 line, and they have a 20W-50 viscosity if you choose, too. I can't speak to using synthetic in a recent rebuild, but I tried synthetic in two of my older cars years back and neither liked it much. Same viscosity as dino oil, but both vehicles started burning oil with the Castrol Syntech I used, so I suspended use. Other folks may have different experiences, but I'll stick with with VR1.
