Review on RuggedMade 12mm Engine Drain Port Hose for Easy Oil Changing by Ahmed Rowe

Great product. I have a home build log splitter that I upgraded with a 16hp Duromax XP16HPE engine. The upgrade worked very well but the oil change was an absolute nightmare. I installed a Drainzit HON1012 12mm oil changer and now I can change the oil without getting a drip anywhere but the drain bucket. I would suggest the website (and DrainZit) list the PITCH distance for adapters. Drain plugs are usually installed in sheet metal oil pans and therefore have a fine thread. However, most 12mm bolts are spaced 1.75mm (roughly) while my drain bolt on the Duromax was 1.5mm spaced. The Drainzit website only lists Honda applications and drain pipe diameters. I had to download a parts list for one of the Honda models listed for the DrainZit 12mm adapter to find that the Honda drain plug spacing is 1.5mm and therefore matches my engine. The adapter fitted perfectly, installation took less than a minute. Before changing the oil, bring the engine up to normal operating temperature.
