I'm a renegade, I guess - or maybe a maverick? :-)
I don't subscribe to the change early and often mantra, I go usually
10-15k/oil change in my vehicles.
I've done this with:
a 2002 Pontiac Grand Prix GTP (supercharged), no problems
a 2007 Jeep Wrangler - 30k miles so far, no problems
a 1999 BMW 323i - 142k miles, no problems
a 1988 BMW 528e - 250k miles, no problems
a 2001 Dodge Ram 1500
a 1996 Land Rover Discovery
and many other vehicles I've owned. Some dino, some synthetic (old mobil 1
formula).
On another note - be aware, there is a new mobil 1 formula, which may not
protect like the mobil 1 of old. Saw that on the net - maybe from some SCCA
racers.
