[C320-list] Fuel treatments (BioBor/Cetane booster)

[Jeffrey Hare]

Even though marine diesel is supposed to have a biocide added, adding a
small amount of BioBor at fillups should be considered just about mandatory.
I've been doing this since the boat was new. Last spring we did a sludge
test when checking the fuel sender unit by putting a tube down to the bottom
of the tank and sucking out a cup or two of fuel and letting it settle in a
clear jar.  It was just as clear as the fuel/water separator bowl with only
the slightest hint of sediment after letting it stand for several days.

Also, we typically add a small amount of cetane booster / fuel conditioner.
Smoothes out the idle and operation.  Depending on what you buy, it also
adds to the lubricity (is that a word?)..

Lower sulpher does reduce the lubricating properties, and also, the cetane
levels generally seem to be dropping in diesel, so we just try to keep
ahead.  It's quite easy.

Local service stations, as well as the big truck stops (where I buy my
diesel), have started converting from Low Sulfur Diesel (500 parts per
million)  to 
Ultra Low Sulfur Diesel (15 ppm).  Does this affect our Yanmars?   Do we
need 
an additive to increase the fuel's ability to lubricate the  engine?
