You sure can. That and Rotella. As for the question is there a better choice, I won't open up that can of worms...........again. But you're good to go.

It appears that the ford diesel oil has more ZDDP in it than the new formulas of rotella do. It even has more ZDDP than even the old higher ZDDP rotella before they lowered the amounts recently.

so the ford oil is a go. it does not matter that it is a diesel oil?

I thought rotella was velveta and salsa mixed?

Nope.

I use the Motorcraft 15W40 oil in the 5 quart jugs from Walmart in my SAN, 6.0 PSD Excursion and my old Landcruiser.

It is just marketed as a diesel oil because it is the viscosity that most light duty diesel pickup engines use. Read the back....there is an API gasoline engine rating just like all the others. The others probably have a diesel engine rating as well.
