Well about to do my first ever oil change and a bit nervous. I have read a couple of threads of people stripping the drain bolt when putting back in. The manual says to have set torque wrench to 18 lbs per inch (units might be wrong). I have heard at this rate it can strip. Should I go less, say 14? The store did give me a crush plug and I assume when I tighten bolt when it closes it should be enough. Any suggestions?
