Jeff [and all]:

As regards the comment you made below that the generators get exercised =
30 minutes a week: Please keep in mind that its sounds like you meant to =
say the diesel engines get exercised [as opposed to the generators].=20
=20
The difference is the generator set also includes the transfer switch, =
wiring and other components. I had one client that fired up the diesel =
weekly, but when a wind storm blew down the power lines, the facility =
was down for a week while they tried to locate a new transfer switch. It =
turned out the building housed a lot more people and equipment than when =
the generator set was first specified and the switch set =
couldn=E2=80=99t support the load. It was very frustrating to have a =
working diesel generator, but unable to power the building!
=20
As a validation person, our motto is if it needs to work, it needs to be =
tested ahead of time =E2=80=93 in the same way you would use it.

We have two 500kW generators at work. Each has a 1400 gallon tank; we =
go through about 500-800 gallons per year. I expect that, despite the =
fact that these generators are having their 21st birthday this year, =
there is still some portion of fuel in the tank that is 21 years old. =
This bothers me a little bit, but it keeps working. We did throw a jug =
of biocide in one year with the fresh fuel.
=20
Having said that, we have a service guy come in twice a year to check =
fluids and change filters, and they get exercised 30 minutes a week just =
to make sure they will run when we need them. =20
=20
Do like the others have said: check filters, check a fuel sample from =
the tank, and let us know what you find.
=20
There exist people who do fuel polishing - they come to your large ship =
or tank farm and run an extra fuel cleaning and refreshing for your =
stored diesel fuel. Might be a bit of overkill on the farm.

Does anyone know of a way to tell if diesel fuel has gone bad?=20
Here is my situation. I have a large diesel fuel tank for my tractors =
on my property (so I don't have to buy 'over the road' diesel.) The =
fuel in there has been there a few years.=20
My newest tractor (a small 25hp subcompact) started acting funny. At =
full throttle, it seems to sputter a little.=20
Could be a fuel problem, but I would love to test the diesel somehow. Or =
is there a way of looking at the filter on the tractor? Or another test =
to do?=20
Related follow up, if the fuel is bad, and I have about 50 gals in a 250 =
tank. Can I just add fresh fuel to it, or do I need to drain out all =
the bad first? What would be a good bad/good ratio to dilute the bad =
fuel?=20
Thanks!=20
