A lot of people I trust have told me that. Is it the same for evey part of the car(diff, tranny etc.)?bjgt2 said:my car has been using synthetic since it had 25000 miles on it, which is a little late for a car. at over 100k on the car all the synthetic will do is clean out the groves and make the engine lose compression. that is what i have heard anyway. feel free to correct me if I am wrong
