Joe has been known to occasionally make a mistake. Look to the right of the drain plug on the
oil plan, clean it off maybe, and see if he inscribed a part number, like 820 or such. If it is indeed a Canton 15-820, and remembering that a dipstick only measures what's in the
oil pan, not the system, then only 7 quarts should be put in the
oil pan -- regardless of what the stick says.
