Another reason NOT to go to Jiffy Lube

Oil changes are easy. We should all be doing them! I think slick-50 is cheating, something to do with it not allowing the oil to cling to surfaces or something. I saw a cool demo of a slant six with no oil pan treated with slick 50 idling all day on propane at a car show/swap meet. Just churning away at about 500 RPM, rods visible under the pan rail

What they didn’t tell you and what you didn’t see in that demo was the grease fittings on the mains. They did that by pumping grease into the crank and rod bearings. If I remember what I read correctly, DuPont refused to sell their Teflon to Slick 50 so Slick 50 took them to court and won. DuPont knew Teflon wasn’t developed for use in engine oils but they had to sell it anyway. That stuff plugged filters and what didn’t get to the filter laid in the bottom of the oil pan.
