Their oil changes are worth the trip. I had around 3 oil changes without any trouble. I did however, go in one day with a "check engine light" and the tech's diagnosis was loose spark plugs. The compression within the cylinders turned out to be okay. His proof that everything was okay was the lack of the check engine light being on during his test drive. Well durr, I can make the check engine light disappear by disconnecting the battery for a few minutes. I left and the next day the check engine light turned on again and I failed my smog check. *sigh* This cost over $200, so for doing nothing, that's a bad deal.
