You make good points. Truthfully, I only got back into doing it myself within the last 2 years. I haven’t done any vehicle more than twice. Somehow I always think I’m too good for the gloves and today will be the day I do it cleanly - only to use the same value in paper towels. Unfortunately, I know at least 3 filters are bottom-mount vertical. They have oil sitting in the galleys above it and spill more as they wobble off. I’ll have to check the drain plug sizes and see. I’m sure there’s repeat sizes, all being metric. I do use brake clean for the final spray since I’m not aware of any other nogrinse degreasers (also haven’t looked)

I do kind of enjoy my 300cc motorcycle. The drain plug is on the kickstand side (good with the lean) and the filter is a cartridge type that lives high on the block and on the not-kickstand side. Basically all the drip is from playing operation with the cartridge on the way out. And it only takes 1.4qt.
