I love Fumoto oil drain valves and have bought them since they first appeared a couple of decades ago. They recently sent me an email about becoming a product tester, which I declined. I don't want to graph out drain times etc for a free valve or two....I already have what I need, but.... Apparently they are launching a whole new "thang." Might be worth a look if you have ever thought about one.... Introducing New Valves & Faster Oil Changes! You asked for it, and we heard you! Fumoto presents a new set of valves for thread sizes M12-1.25, M12-1.5, M12-1.75. The new valve body is 29% larger and the oil outlet size is nearly 60% larger than before, with a wider drain diameter allowing for a quicker rate of flow for faster oil changes. Available now! We tested the valve using water on a demonstration oil pan. The rate of oil flow from an actual engine will vary.
