EEK! They've taken the sulfur out of Marine Diesel!



I was talking with a marine diesel mechanic and he told me that they've now taken almost all the surfur out of marine diesel. I knew that the on-road stuff was low sulfur now but I thought us (off-road) boaters were still polluting. Apparently not!

He told me that since diesel fuel is the primary lubricant for the high pressure fuel pump and parts of the injectors that those are the parts wearing out rapidly now. He said that Seattle Injector has had to hire more staff to deal with the increased demand of suddenly worn out $3000 injector pumps.

His recommendation was to add a lubricant additive to the fuel. He likes the biobor brand but says many other brands work.
