I watch for the sales from the National chains that I think try to do it as an introduction. I recently got a 12 dollar oil and filter change from Pep Boys and the oil and filter would have cost me more than that (forget the labor and yuck factor). I saw it on an A-frame sign for a recently opened store but my friend saw it on line and did the same. My only caveat is look for fine print. Some shops have surcharges for Vans or trucks, or they try to "up sell" other products. What is your opinion on oil change deals and do you have any you know of running now?
