So, Its time for my oil change, and I feel completly comfortable doing it except, I dont have a torque wrench so I wont know how many footpounds of pressure im putting on the drain bolt. A buddy said just do it then putt it down to the stealership and have them tighten it. Should I break down and buy one or do you guys have a better solution. Sorry if this is a dumb question im new to doing my own mechanics.
