Subaru is the worst in my personal experience. Several years ago I had gone ahead and changed the air filter since it was filthy and because I knew they would want to do it on the oil change that was scheduled in a week or so. $15 instead of their $70. At the oil change appointment the service advisor brought a filthy filter to me and said they were going to change it and they could give me $10 off as part of the appointment. I said “I don’t know where you got that but if you look at my filter you’ll see it’s clean since I just changed it. How about I show your manager my receipt for it?”
He looked like someone walked on his grave, apologized, and gave me 10% off the oil change. I never went back to that dealer, and my wife kept that car in the divorce so I don’t know who she goes to now, but definitely not them.
Learn to change your own oil people. You literally only need a socket wrench and and a drain pan. You don’t even need to jack a lot of cars up if you don’t mind squeezing under.
And a filter wrench, and a way to dispose of the oil and filter, and a place you’re allowed to work on your vehicle (many apartments disallow it) and I don’t think it’s fair handwave the jack and jackstands and possibly wheel chocks that most cars need to safely and comfortably get to the drain plug, plus gloves and safety glasses. I have all those things so I do my own oil changes but I’m not pretending it isn’t a hassle and it’s barely a cost savings. I think people should learn basic car maintenance because it’s outrageous to be completely ignorant of something so important and expensive in your life, not because paying for someone else’s time and experience is a bad thing.
