[s-cars] Diesel oil?

[Lee Levitt]

Here's what Mobil says about using Mobil 1 Delvac (which I ran in my
turbodiesel) in a gas engine:

Mobil Delvac 1, which is designed for heavy-duty diesels, meets most diesel
engine oil specifications, and also meets API SL certification. And because
Delvac 1 operates in a different environment - diesel engines run longer,
generate soot and run hotter, it contains different types and amounts of
additives than Mobil 1. Even so, Delvac 1 still meets API SL certification
for gasoline engines, and because of its high performance, we would expect
it to do a good job of protecting your gasoline engine. If you use your
gasoline vehicle in "heavy-duty" service, Delvac 1 will provide many
benefits compared to conventional oils. When compared to Mobil 1
performance, those benefits may not be as obvious, and in fact, Mobil 1
would be expected to outperform Delvac 1 in many gasoline applications.

I'll stick with Mobil 1 Extended (for gasoline engines).
