It's not as funny if they over or under torque the drain plug. My first and last ever oil change "at the certified GM Hummer dealership" they left out a bolt on the skid and soaked everything with oil which immediately sucked all the dirt to it like a magnet.
Next time I tried to remove the plug and filter they had rounded the plug and mega tightened the filter but they only charged me $50.
I get $9.95 oil changes at the GMC dealership so I don't have to dispose of the oil and they even have a funnel adapter on the oil drain stand for H3's and there is a dedicated torque wrench in the change bay.
