My sister took her car for an oil change at the local gas station/mechanic. She was getting an inspection done and I was too busy to change her oil this week so she asked for an oil change. Her car takes 2.8 quarts of oil and a tiny filter. They charged her $37 for a standard oil change not including a $2.50 disposal fee. Seems pretty steep for some Formula Shell bulk oil. They raised it $10 over the past few months....from now on, if I am too busy I will have her take it to the local tire and brake place...they charge $24.99 for a standard oil change. Is $37 a lot, or am I just too used to the DIY price?
