High Mileage Motor oil?

You make good points, and like you said most everyone has already made up their minds, and if you were running a drag motor with a blower and nitrious, synthetic would be good.

I run synthetic in mine, mostly because I get an extra sense of security about the insides of my motor.

Thanx Vonski

What about the synthetic properties that allow it to handle higher opperating temperatures? Would it be benificial to run synth motor oil in motors that run at higher temps and have tighter tolerances? I am pretty sure that BMW requires synth in all of their motors, but they also recommend something like 10K oil change intervals. Toyota also runs synth in their car V-6's and recommends 7500 oil change intervals. I also think that Land Rover uses synthetic in all of their vehicles, the new Range Rover for sure uses synthetic.

Is there something to using synthetic in new motors?

I don't know about BMW in general but BMW of murray tells me that they use Valvoline Durablend in their service dept. The service intervals are about 7,000 miles but they claim that the computers take in to account driving conditions and adjust the interval accordingly. The oil and filter in my wifes gets changed every 3,000 with full syn I don't care what they say.
