Old fuel

Bus Driver · Aug 17, 2011

Often people here ask how to use old Diesel fuel. And some of the suggestions say to throw it out and get fresh.
Today I did some heavy duty rough mowing. Trees up to 2" diameter. Tractor is 1977 Long rated 36 PTO HP and the mower is old 6' Howse. The fuel is over 20 years old. It passes through a 5 micron filter on the hose as it goes into the tractor tank. The tractor ran perfectly.
The oil man owed me a favor at the time he filled my tank all those years ago and sold me the oil at $.43 per gallon. I still do not waste it as buying more will be expensive.
But today's gasoline often does go stale quickly.

How big is your tank? I barely put any hours on my equipment and still use 150-200 gallons a year.

Diesel ages well, if the tank is at a more or less constant temp, with not a lot of early morning or late evening pumping, to draw in moist air. Even then, all you have to do is use a good filter and fuel drier. I saw a bulldozer that sat for 40+ years start right up on the old fuel. Also, the old gas lasts a lot longer than the new alky-hol gas, of today!

Your fuel is still good because it is not bio fuel. The bio fuel will not last like that, you can get all kinds of things "growing" in bio fuels

I love my night job! We have a build'n that the city didn't want to run 220 to so we heat it in the winter with a torpedo syle "ready heater". Our old heater was older than dirt they found some where and started have'n problems several years ago. Our great maintenence man said that the kerosene was old, he found some where online that it would only keep a year. They have it delivered 300 gallons at a time. My boss was freak'n out becasue there was no way to legally get rid of 100+ gallons of kerosene every spring and it would "go bad" over the summer. I told her if she wanted it gone it would be gone, that's my job, do what she wants. I always wanted a 150 gallon pickup tank and pump but just didn't have a reason to spend the money. She gets the kerosene "gone" and I had a reason to buy the tank I wanted.

Accually, what I see on here, people say run old diesel, drain and repalce old gas. Maybe that has changed on here to like everything else does!!

Algae infections happened in old diesel too. Its mostly if the tank is warm and has had contact with an infected fuel source.
