Anyone familiar with this stuff? www.zddplus.com

Great. And it's ONLY $10/4 Oz bottle. Since a 292 uses a 6 quart oil sump, not 5 quarts [like V8s] do I need to add 5 Ounces?

Hello,
If you want some more info concerning ZZDP levels in oils check out this post by SWHEATON on Team Chevelle. He spends a good portion of his time researching the subject for flat tappet users.

From the information these guys have provided, I've started adding the STP 4 cylinder treatment (Red Bottle) to my crankcase in an atttempt to buffer the ZDDP levels.

Cheers,
