Terrible. I just went in for a quick oil change and check. Left with an overfilled oil pan that started to cause my engine to smoke.
It didn't smoke in all the years I had done my oil changing. But the week after I took it in to these clowns it starts smoking on startup. I went back to complain but all they did was replace the oil again, right up to the top fill mark, they said, then added some oil additive to top it off. The engine smoked off and on at startup for the next few years. I've never been back.
