I just run the Driven 10-30 Hotrod oil for the last flat solid I had. Before that I was a Brad Penn guy and it was very good too. No failures with either oil and no additive. Gus

10w30 VR-1 in my current 540" Hemi for 5 years now. And in my 500" wedge for a decade before that.
No additives, no problems.

Once it's broken in the need for additives is less important. Too much of some types of oil additives, like zddp, can supposedly lead to the metal corrosion as it alters the oil composition. Bob is the Oil Guy is a good site to read up on different types of oil and additives. Some real chemist geeks on there that deep dive into things way over the average person's head. Found this too while reading about camshafts and oil. https://www.nonlintec.com/sprite/oil_myths.pdf

This is a testament that once broken in a higher zinc content is not needed.

I used the Driven Hot Rod oil on my last SFT, and Brad Penn on the previous two HFT's. The new SFT that is in there now will also be Driven HOT ROD with no additives after the initial break in.
