Wal-Mart Informative - Price changes
Wal Mart actually didn't change any policies reguarding using your own oil, the thing you gotta remember is, oil changes are a package deal. Oil changes consist of 5 qts oil, a oil filter, fill washer fluid, Transmission fluid fill, power steering fluid fill, etc. Now add all quart prices together and see what the price comes to, kinda close to the price of the oil change, and remember they do vaccum your cars out. I have seen some cars come in with ALOT of gross things on the floors, this also includes finger nails as well... so next time when you complain about prices, think about the condition of your car.
