This is just a crazy opinion question - but what is the deal with that cheap Pep Boys Pro-Line oils?? Who makes them and how bad can they be? I, personally use Mobil 1 fluids in all my vehicles, but I have a cheap nieghbor who uses the Pro-Line and am wondering how it is. I guess I got a little alarmed when I saw cases of the stuff at a local garage too...guess that's how the low cost oil changes can be offered. I always explain to my friends (of which many have been converted) that for the price of an oil change you can do it yourself and use better products.
