I'll stick with what the manual specifies rather than what some service advisor says. How many service advisors specified the wrong motor oil? Diesel fuel, for the colder months , at least around here is "winterized" to help prevent wax crystal formation (fuel filter plugging). Needlessly running excess crud through a high pressure fuel pump at over 29,000 psi just makes me cringe.
