old fuel
hey guys,
i recently inherited a 83 blazer, diesel (i know, chevy) anyway im trying to clean it up and sell it (dont want a chevy sitting in front of my house). the problem is its been sitting for 5 years and the previous owner left a full tank of diesel in it. so... when i drop the tank, what do i do with 20 gallons of diesel? a friend told me that using two bottles of diesel conditioner would make it useable, but i dont like the sound of that. any tips or advice would be great. thanks alot

so the 83's a diesul? being a Benz head, ive come to realize that diesul just doesnt expire like gasolien does... It shouldnt at least.
When storing a vehical, they did you a favor, because the full tank cannot rust, because theres no way for the water in the air to condence, because there is NO air in it...
My 76 benz sat for 7 years after my father passed away (may he rest in peace)... new batt, new oil... started up first try, with no ill effects from the 7+year old diesul...
So Id run it, mabey ad a can or two of SEAFOAM to it (great stuff... really cleans it out)
Before selling our 97 van that sat for 2 years, 2 years ago (sat from 01-03)... had half a tank of gas in it... filled it up and drove it for a while... ran like $#!^ for a tank, and then ran progressively better... Gas degrades, Diesul doesnt
~Nate (o, before u sell, do a full chassis lube for $30)
*EDIT*also, what makes you want to drop the tank?*EDIT*

The major issue with old diesel fuel is you have no idea if there was already moisture in it when it was parked. If there was, there WILL be algae in the fuel that grew at the seperation between the fuel and the water. It will incessantly plug fuel filters, and become a general pain to deal with. I had a boat with 800+ gallons of old fuel in it. I was changing Racor fuel filters about every 10 hours.
Dump the fuel, making sure you get all water out, fill it with fresh, and add a good biocide. You'll still probably end up changing filters a couple times, but it won't be nearly as bad.
