My GMC pickup - I had a coupon from my dealer for an oil change…It was real cheap. I dropped it off since it was about 100’ from where I worked and picked it up after work. I opened the hood and there was my bright Orange Fram filter. I pulled the dip-stick and the oil was NOT clean. I was furious. Service manager insisted that they did the oil change. I showed him my Fram Filter…He shut up and brought out a tech who drove car on lift as I watched and changed oil and filter in front of me. They probably could get away with that with their customers who only go to them for their service.
