While I was sitting in a Pep Boys waiting room a few weeks ago while having tires installed, a younger guy came in for an oil change. He was quoted $117.00 for a Pennzoil synthetic oil and filter change. He had a coupon so he ended up paying $87.75 plus tax plus a disposal fee so it came to slightly less than $100.00
While not denying that Pep Boys has a right to make money, when I change my own oil, it costs me between $35-$40 (for synthetic) and my time.
