Well, I guess I am lucky as part of my car deal, I got 3 years (4 X per year) mobil 1 oil changes from my 5-Star Chrysler dealer. I didn't realize the value of this until now. I have bought 3 other vehicles from this dealer, they also wash and vacuum your car with the oil change that is free. I know I have to schedule it, but I am in and out in about an hour.
