Honestly, I have been taking my cars to Wal-Mart for 90% of my oil changes in the past 7 or 8 years and have never had a problem. The last time I had any mechanical work done, it was done by my boyfriend and before that, my friend (who is a mechanic at Ed Voyles Honda) and I did it together. Girl power! lol
FWIW, the pay scheme (hourly + commission of some sort) is pretty much the same at all these places IME. The ex worked at a Tires Plus, Deana works at a dealership. The more they sell ya, the more they make. Nothing really wrong with that in theory. *shrug* The thing is, some will sell you only stuff you need anyway, some, stuff you might need or will eventually, and some are just out-and-out unscrupulous bastards. Learn a little about your car and be prepared. I have had people try to sell me stuff that was utter bullshit, and it feels really good to be able to call them on it. ALWAYS have them show you what they're talking about, too. If you go to one of these oil change places that tell you they need to do something else that would make your car "unsafe" to drive even to your regular mechanic or dealership, that should raise a serious red flag. Call your regular guy and see what he says. If you don't have a regular guy, drive it somewhere else and get a second opinion.
And whoever said it was absolutely right--stick to your guns: "I need an oil change, and nothing else." Specials on oil changes are supposed to draw you in to get other work done.
Btw, places that do emissions inspections do this bullshit, too.
