Way back in December of 1987, I bought a brand new Mercury Cougar. The dealership threw in free oil changes every 3K miles for the life of the car. I tried to have them lower the price of the car if I had them ignore the oil changes, but it was the dealership's policy and they wouldn't budge.
Since I then lived in an apartment and working on your own car was prohibited, I took it to the dealership for the very first oil change. On the very first oil change, they stripped the oil drain plug. When I took it back for them to remedy their mistake, I watched them drain the oil in to a dirty oil catch can, replace the plug and then put the old oil back into my car.
I never went back to that dealership again and I then changed my oil in the parking lot of my apartment complex after that, usually at 2:00 AM where I had the least chance of getting caught. Yes, I did get caught once.
