When changing the oil on your Cummins B series on the drive, do not lean the old filter against the garden wall intending to empty it later. You'll find that as you slide out from under your truck having torqued up the drain plug, you will have kicked over the filter spilling about two pints of old oil all over your drive just in front of your garage. On the positive side however, your vocabulary will have expanded slightly.
