But when it comes to pumping new oil from a gallon container into the SM420, I need to first pour the new oil into a smaller bottle that has a pumper on top. I believe that if I attach a pumper to the top of a gallon jug, it will not fit under the truck. Do some just remove the stick shift and pour the oil down into the stick shift hole?
Hope all are being safe.

Thanks Jerry. I've always wanted to try that method and now since my body is starting to fight me in crawling under the turd as often as I am use to doing,,,,,
