Hmm, good thread. I guess next time the oil change is due in my Z I should just go ahead and tell the dealer to change ALL fluids. It's got over 60K miles on it and I have no idea what the previous owner may have done. Better to assume the worst, I guess, rather then assume the best. From what I have seen of Champion Chevrolet in Tallahassee, if I bring my own fluids, they won't complain at all about using them for my vehicle. Just had the oil changed not that long ago, so I may be a couple of months.
Heck, I just remembered.... I didn't reset the oil life indicator last time...
