Is anyone concerned with the use of the new Ultra Low Sulfur Diesel in our mowers? Supposedly the new diesel lacks the lubrication of the old diesel and is hard on injector pumps and cylinder wear, etc. I was reading on a diesel truck site about using TCW-3 spec 2 cycle marine oil mixed at a ratio of 100:1 to 200:1 in the ULSD fuel. The TCW-3 is an ashless formula and should actually help clean the engine in these low concentrations. Just wanted to hear peoples thoughts on this.
