I do every time. I already paid for it, and there's no incremental cost to use it more, and I like knowing it's torqued properly. I was very surprised to learn in one of Project Farm's videos how small changes in torque make a massive difference in the clamp load. For example, going from 40 to 50 ft-lb, it increases the clamp load by 1500 lbs. Enough for me to care enough to take the torque wrench out and do it right each time. I don't torque the filter though like some do. I just do it by hand, and I can loosen it by hand when I drain it.how many others here are actually using a torque wrench on the drain plug.
