Glad to hear you got a handle on it, and by way, congrats on last meet's
record.

Soooooooo........ Here's a question pertaining to diesel tow  
vehicles. Diesel
internet groups rave about fuel additives such as Diesel Kleen and  
Stanadyne.
I have believed in additives, but this is my first diesel (Duramax)  
and as I
understand it, there is merit in these additives, especially since the
long-term effects of low-sulphur fuel are unknown as yet. Anybody  
care to
comment on whether this is snake-oil or a good thing?

I haven't run any additives in my Duramax-by-Isuzu 6.6L -- and at  
135,000 miles it's apparently doing fine.  No issues of any kind - so  
far.  I do fill at the off-road pump now and then -- that's high- 
sulfur, and also not quite within the rules (no road taxes) -- so my  
engine gets some sulfur.

Our road trucks are both Caterpillar 3126 engines -- and we don't put  
additives in those tanks except for the occasional anti-gel during  
the coldest weather.  I don't use it at all in my pickup -- but I  
keep the p/u in the garage at home, so the temps don't get much below  
zero.

Yes, there's a chance that the diesel, when stored for a long time --  
will develop some algae in the tanks, so consider putting something  
in there to retard the growth.  I know there's something -- I don't  
know the name of it.

I doubt that gelling is a problem for those of you in the warm  
climates, but to help reduce it up here I wrap a layer of fiberglas  
insulation around the fuel filter during the winter, to keep that  
device from getting too cold.   We haven't had an ice up for a couple  
of years.
