Shouldn't be a problem. My understanding (coming out of personal research to figure out what oil is best for my diesel Jetta) is that oils formulated for diesel engines contain additives to maintain emission standards and deal with the heavy soot byproducts of diesel combustion. Gasoline engines don't benefit from these additives, and wouldn't be harmed by their presence in the oil.
