This is a first. Mobil 1 has always recommended "follow your owner's manual" which is usually 6000, 7500, or 10000 miles maximum.
But now they've released this "extended performance" oil that they say can go 15,000 miles! "Guaranteed." I wonder how well it will sell? Anyone on this forum plan to try it?
I'm already running Mobil Delvac 1 (truckers oil) in both my diesel & gasoline cars, so I doubt I'll switch, unless someone can give me a good reason to do so?
