Bride and I had an out of body experience, today. Changed the filter on the Cummins 5.9, and never spilled a drop. She plucks the old from above after I loosen from the bottom. She fills the new with oil, lowers it to my hand from underside, and I screw it on. Not a Drop! Of course, we're married 53 years, so this could be dangerous grounds for newlyweds.
