We have a SnapLube up the street from us (Citgo). They do general maintenance (oil changes, belts, transmission flush, coolant flush) as well as inspections. Years ago, they were decent kids working there...but now those same kids seem to be under the pressure to make some money.
We take all of our cars there for inspection only. We used to be able to get in, drop off some used oil, get inspected and leave. When I went this past year, they started fiddling under the hood and looking around. They found that the belt on my Taurus was frayed and they "couldn't pass me on the safety inspection". I thought it was [censored], but I let them change it because I was aware it was about 10 years old.
The next time, my wife took our Forester in for inspection. This time, they would not pass her on inspection because the year old windshield wiper had a crack in it. She had them change it, but NC inspection says it only has to "clear debris". This was a crack in the rubber.
Lastly, I took my Maxima in to be inspected. I *meticulously* maintain and clean the engine of this car. They spent a good ten minutes...when I saw them poking and pulling I went out and asked what they were doing (inspection on the engine should be through the computer port alone). He said the give a "complementary safety inspection that our customers appreciate". I told them I didn't and they should stick to the inspection and finish. He said my car was in good shape but I should get the engine oil cleaner treatment they offer. I told them that was not recommended by the manufacturer and that several Jiffy Lubes had been sued for engine damage on poorly maintained cars that went through the treatment. One of the other techs came over and asked "then why does the Nissan dealer offer the service?". I had to explain to him that the dealer operates independent of the manufacturer and it is the manufacturer who does not recommend it.
Ugh! Never again.
