Default Oil suggestions ...

This was discussed before but I cannot find the thread ... just completed the break-in of a 454 with Comp Cam flat tappet hydraulic cam ... installed in a 71' Nova. What is this panels suggestion for oil to run in this motor? It presently has Driven BR 15W50 break-in oil and I need to change it soon. Thanks in advance!

Craig

All I use with flat tappet cams. Haven't lost one yet.

I understand the Gibb's Driven product is great as well. You may get as many opinions as there are active members here.

I've continued using conventional oil with ZDP additive. Just bought the Driven oil for the 496 in the Chevelle. I haven't changed it yet, so no opinion, but the Gibb's oil has a good reputation as well.

I use Brad Penn 15W-40 or 20W-50 in my Z/28 and SS nova.

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'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.

Anyone use the new Castrol GTX "Classic"? It's available cheap at WalMart and says it has increased zinc specifically engineered for classic cars... It's only available in 20W50, but is less than half the price of Penngrade.
