The 1000mi mark is not arbitrary at all. After having built both high
performance motorcycle and automobile engines for over 20 years. For both
street and racing. As well as countless hours dyno testing said
combinations. I have discovered , and been backed up by a number of
others, that the two most important times an engine is run is the first 30
minutes for the cam bearings or any other style of shell or babbit style
bearing. At which time the engine should never go under 1500rpm, this is
so adequate oil pressure is maintained. This should hopefully done at the
factory. The second interval is for the seating of rings and roller
bearings. This is usually accomplished within the first 400 or 500 miles.
Though it is usually suggested to go further just in case. The other
reason to change the oil at the first 1000mi is the assembly lubes that
are used to assemble and ship engines. The specs that usually come from
the factory are usually set very much on the safe side. Next thing you'll
be telling me is front wheel drive is an advantage. The only advantage is
it cost them less to make your car, they can make the entire drivetrain in
one piece.
