    oil change

    I'm changing my oil this weekend and recently saw a commercial for high milage synthetic oil...

    my 2003 has 166,254 i was planning on moving to synthetic but recently heard that i should just stick with the regular motor oil. anybody swear by synthetic or otherwise, and any advice on going with the high milage oil or sticking with regular 5w-30 would help

    the big stigma about synthetic oil is that it "creates" leaks.. it doesn't, but what it does do is a combination of things.

    1 it washes the miles of built up sludge away from the inside of old seals.

    2 when that happens the smaller and more uniform molecules that make up synthetic oil will "find" leaks that irregular shaped dino oil did not.

    It never hurts to run a synthetic, but beware that it may make leaky seals worse or current damp seals start to leak.

    What you want to do though, is stay away from the "high mileage" formulas, these are designed to get seals to swell supposedly cleaning up leaks. Well after they swell like that you really cant go back to a normal oil. Your then stuck on the high mileage stuff.

    my personal, and I'm sure others will touch on this.. I have a preference toward a synthetic blend in older engines. It lubes well and holds together better than straight dino oil.
