Oil With Zinc

So, I was talking to the Agip oil guy at the Pittsburgh Vintage GP and he says what I want is their diesel oil! Whats that all about?

Does anybody use diesel oil in the gas motor?

Diesel oil was a good workaround until two or three years ago, when the amount of ZDDP was reduced in those, too. Diesel oil rated CI should have adequate levels, CJ probably does not.

I use Valvoline All Fleet 15W-40, which is a "universal" oil rated SL for gasoline engines and CI for diesel. It has something like 1200 ppm ZDDP, which is just fine for flat tappet cams. Most parts stores carry it.

No! Thinking with your dipstick would be Ginger. Thinking with the big head would be Mary Ann.
