Two
diesel 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.
