The torque for oil drain plug varies depending on the make and model of your vehicle. However, in general, it should be between 15 and 30 ft-lbs. Be sure to consult your owner’s manual for the specific torque rating for your car.
If you are changing your own oil, it is important to properly torque the oil drain plug so that it does not leak. An over tightened plug can strip the threads, making it difficult to remove next time. An under tightened plug can vibrate loose and cause an oil leak.
