You guys are starting to worry me. What's wrong with Rotella T5 10W30 and a bottle of ZDDP Plus?

P.S.
Found this pretty interesting.

Thank you for the link, I found it interesting. I have run T4 in my 99 Cummins since new.

I use Valvoline 15W-40 conventional and add Zinc.

I wouldn't recommend diesel oil to anyone with a gasoline engine especially if the engine is of the high-performance variety. Diesel oils are not formulated for rpm's of any significance as diesel engines rarely see 4000 or so.
