Has anyone been able to get their cars serviced at somewhere other than the dealer? I've got nothing against my dealer except that it's not the most convenient place to go to. There's a garage I take my Chrysler T&C to around the corner; I could also go to Walmart to get the oil changed there if I wanted to while I killed time there (or the Costco next door). I asked the Walmart guy today if they used 0W-20; he seemed kinda puzzled as to what that was.
