aa. Trust. Last time at Jiffy lube(MANY years ago) i left and got on I5 to visit family. LUCKILY i had an oil pressure gage and saw my oil pressure drop. Got to the side and had to be towed. Turns out they hadn’t tightened the nut on the pan. It had come off and drained all my oil on the freeway. Went back the next day and spoke to the manager. He basically accused me of trying to get a “freebe”. Won’t EVER go there again. There are a lot of good auto repair businesses and YES trust is important even for an oil change.
