Has anyone ever used the mobil one 15,000 mile motor oil in their cars? I was thinking about trying it but I am leary of not changing my oil for that many miles.
I have, and I changed the oil after 7,500 miles.............. waste of money I know but I was to much of a pu$$y to let it go that long. My father runs regular Mobil One synthetic in all four of his vehicles at 10,000 mile service intervals and has never had a motor problem, he doesn't race though.
