Has anyone run Sea Foam motor treatment in a Kubota diesel? I live in Northern Ontario and the winters get pretty cold up here. I received my new BX 1870 last week and it would run for a bit and then quit. Dealership sent one of their techs down and he removed and replaced the fuel and both fuel filters. Runs like a top now. Turns out the dealership has water or bad fuel in their tank. The tech recommended running Sea Foam in the fuel. Any advice, this is my 1st Kubota.
