zinc oil useage?

Again, more zinc, less power. That’s a FACT.

Not sure on what is used for base oils for diesel oil but it could be Group III, IV or V base oils or any blend of those three depending what the intended use of the oil is. And the decision on what base oil(s) to use and in what ratios dictates what the additive pack will look like.

If diesel oil was the **** it would be in every Pro Stocker and Comp car running. It ain’t.

Companies like LAT and Torco make 20 plus engine oils. That’s not counting the various grades of oil.

They don’t do that because it’s a better business plan. It’s not. Each oil fits a specific application and then you narrow down the grade.
I don’t disagree, but what is more? What’s the PPM is your favorite gas oil vs my choice of diesel oil(test at ~1100 ppm)

Your answer on the base oil doesn’t support your claim that it is different from a gas engine. Those are the same base oils that a gas engine use. What make the difference is conventional vs synthetic or blend.

A 10w30 that’s rated for gas and diesel, with a similar PPM of ZDDP will have no ill effect on a gas engine.

I ain’t saying diesel oil is going to suck your knee caps through your pee hole, but given the right viscosity and ZDDP content, it’s going to get the job done.
