can diesel fuel go bad????

[bullydoller]

i have an 86 6.9 that i use to drive everyday until about 3 years ago, truck has been sitting with both tanks full for about three years, i start it maybe once a month and let it run so my question is with diesel being 4.00/gallon can i drain the fuel out of the old rig and burn it in my 6.0

[thbd77]

I wouldnt do it being that old. Fuel does get old

yeah it may pass through the ole 6.9 ok but the 6.0 is alot more complex and would most likely cause some problems

[bullydoller]

yeah thats what i was thinking thanks guys

Since diesel doesn't really "age" the way gasoline does, actually what I would be more concerned about is the growth of "biologics" in your old fuel. If you truly wanted to use it, you could have it tested and possibly treated, but that would be overkill for just a tank of fuel.

PS. It would certainly cause you problems by clogging your fuel filters and could cause injector problems.

We had a bad case of what ever grows in diesel fuel "biologic" and we have a irrigation company and have to blow all the water out of the systems in the fall. Well we use tow behind diesel powered air compressors and got bad fuel from the tank in them, it was a month long battle to get everything worked through! I made sure that wont happen again, we treat the fuel in the big tank, plus as we put it in something else and the fuel we got had just set over the summer in our own tank, bad fuel = bad headache!
