MYTH:
You should break in your engine with
conventional oil, then switch to Mobil 1.

FACT:
The tighter tolerances and improved machining of
today's engines have reduced the significance of
the traditional engine break-in. Few manufacturers
call for any special consideration. Since Mobil 1 is
factory fill in Corvette, Viper, Porsche and other
high-performance vehicles, engine break-in is
obviously not an issue with current-generation
vehicles.

If your engine is an older model that has been
rebuilt, you may wish to follow the original engine
break-in schedule. In this case, where you may be
changing the oil after just a few hundred miles, you
might want to use a conventional oil initially and
switch to Mobil 1 once you have reached a
mileage that permits longer oil drain intervals.
