True, but still doesn't mean it's necessary. You sound like Jiffy Lube and their 3,000 mile oil change commercials. Changing your oil every 3k is cheaper than a new engine. Once again, it's a true statement but that doesn't mean it's necessary.

Nothing worse than a hot transmaission. I lost a trans to heat with the Redline stuff back in 05. The oil had about 10,000 miles on it when I ran the 150 class in the Silver State. The trans was giving me problems during the run and once past the finish line and off the gas it spun a main shaft bearing during the coast down to the pit area. I was lucky to make the 300 mile drive home from Nevada

To do it all over again I would have installed fresh Castrol just before the run in 05. I don't know if it would have preserved the trans, but, I am sure it would not have hurt it either.

Like others have said, I would rather spend a little extra keeping everything above the acceptable standard of maintenance than risk the cost of a rebuild.

The castrol 10-60 from bmw seems to be the right stuff...
take it from another open road racer(me) and Bill.

redline is extremely iffy and as I've read it in the past. Bad or Wrong oil has cratered many ZF's if you don't get exactly the right stuff. Never heard of the Redline MTL whatever that stuff is but learn from the forum's experience...just get the castrol...oil and metallurgy...it's voodoo we've learned the hardway.
