I change my own oil , rotate my own tires , flush my own trans fluid .. only beacause i don’t trust the goons at the oil change places who try to put the drain plug back in with a impact gun .my buddy works at a ford dealer , and they have sent 2 cars down the road with no oil in them after oil changes and seized the engine .... Plus the knuckle heads who do oil changes at the dealships are entry level guys ... they don’t know shit about cars !
