took truck in for oil change. Serviceman was going to air in my tires before I stopped him. I told him I have nitrogen in the tires(per green stems). They charged me three times the amount to top off my tires that I paid to get them done. I bought the truck there but I don’t have to get it serviced there. Mechanics are not experienced, did not let me know the charges for the nitrogen before they put it in. I believe in supporting the local economy by using business in my city but I am making an exception with harbin’s dealership! I will not use them again nor will I recommend then to anyone else!
