You better check. Like I said there are some engines manufacturers that want you to run this in your car from the get go. But for the most part syn. is so slick that it will not allow your rings to break in properly. Bad news there. As for why does everyone trust the dealer? No one trusts a car salesman, the same people run the shop as run the salesman. I just don't get it. Most of the dealers here is Portland are more crooked then any of the independent shops, less Goodyear or Firestone I suppose. Those two seem to be the worst.
