I had the oil changed in my 2014 Ram truck about 3 weeks ago. While I was checking out the manager told me that I had requested conventional oil and synthetic needed to be used. ($50.00 more). He told me that I was ruining my engine and the factory recommended synthetic. He went on to tell me the conventional oil would breakdown because of the heat generated from the top end of the engine since it was all aluminum. I have been using conventional oil since I purchased the truck and he is completely wrong. Mopar recommends conventional oil and recommended not using synthetic oil before 30, 000 miles.Then they said it was personal preference after 30, 000 miles. I am wondering how many other customers has he lied too?
Today, March 27, 2019, I had the oil changed in my 2013 Kia. I asked for a tire rotation also. I got the car to the shop 1/2 hour early. I asked the manager how long it would take and he responded 1hour. 3 hours later I called the manager and asked if the car was ready and he said yes. I went to the shop and the manager told me they hadn't rotated the tires. I asked why and he told me if you rotate your tires too often they will "cup" and ruin the tires and they looked ok to the technician. I almost laughed in his face but decided I needed to complain to someone to stop this lying! Thank you,
