mechanics in our area (one of them does my tractor repair) both suggest that modern diesel
(low sulphur) has pretty poor lubrication qualities compared with the old 500 ppm sulphur stuff. I had a tractor engine
the other day with a sticky injector and the recommendation was to throw a couple of quarts of transmission
fluid into the 20 gallons of diesel in the tank. I did this with the troublesome tractor (85 HP Perkins
4-cylinder diesel) and it has run perfectly ever since. Once in awhile I use injector cleaner in a car, tractor or truck engine
but I understand this stuff can be hard on injectors if over used. But lubrication is important, too.
Does anyone used additives in the fuel
for their boat engine? I'd never heard of transmission
fluid as a lubricant, but it seems to work well, burns fine, causes zero smoke, and results in no loss in power.
