Wayne and Richard, you're both correct. Richard I'm glad you had the
diesel polished, for peace of mind. That didn't hurt a thing.
Wayne, you're also correct that quality diesel fuel will last for years.
Where the problem lies is when operators will use 'bio-diesel' the mucky
algae loves that stuff! In a few months the junk starts growing and it
clogs filters and can foul the tank and fiel lines.

Engines run great on bio-fuel but it can't sit long. You find it mostly
sold at truck stops. marina's use the good stuff for that reason...

Regular diesel as well as kerosene will grow critters if water is present.
Alaska fishing boats have a, I think it is called, a day tank. The regular
tank feeds the day tank. Keeps you from having a huge mass of dirty fuel
feeding the engine. I think the day tank allows the stuff to,settle, as
to kerosene, they use to separate different products going down a delivery
pipeline with a water slug. They military had some jet crashes. Was
plugged filters from critters. The water slug allowed enough water in the
fuel tanks to grow the biological.

You have to consider how old the gas is that you are treating. The
clock starts ticking the minute you fill your tank. Fuel stabilizers
only stabilize, they can't help old gas.


How old is the gas by the time it's delivered to your local gas station?

Someone told me once that I should put an additive to the fuel in the
first diesel powered boat that I had (unless I was using it daily and
going through a lot of fuel quickly). Diesel fuel is a breeding ground
for "bugs" that can clog fuel filters if they get too bad. But I
mentioned it to the marina owner who sold diesel. He said the
recommended additive to prevent bug growth is put in the fuel by the
distributor, so don't waste my money on it.

Maybe gasoline is also stabilized at some point after refining but
before delivery to retailers.





The age of the fuel would have a lot to do with your distance from the
refinery. My point was that adding stabilizer early would yield the
best results. Adding it to stale gas is a waste of money.

Certainly don't disagree with you. I have a hunch though that gasoline
is probably several months old by the time you put it in your car.
It isn't stale, but it isn't exactly fresh.

There's no way to know for sure.
