So i'm wondering if it will harm anything if i switch to synthetic after soooo many miles. If it wont harm it how would i go about doing this? any special ways? :confused:

^ Drain, New Filter, Refill. Done, shouldnt harm a thing... I have heard something about going from synthetic to conventional being bad, but I can not clarify more on that.

You'll probably kill your motor faster with the synthetic. It'll burn off quicker and therefore the likelyhood of the bearings sucking dry increasing a lot.

i had a bad experienced switching to synthetic with my high mileage wagon. i had to replace most of the oil gaskets to prevent those damn leaks. now i run synthetic and it runs smooth.
