Default Free Diesel

Hi there,

I have some old diesel fuel that has been sitting in my slip tank for about 2 years and I need to get rid of it. There is about 60 to 80 litres.

I'm in NE Calgary and if anyone could use it I would be happy to drive over and give it to you free of charge. It's likely not good anymore but I know some people still use it for an oil burning furnace and things like that.

Cheers.

Diesel does not go bad quick like gas. If there is no water or rust in it then its fine. I have bought old trucks that had 20 year old diesel in them and the still ran.
Gasoline starts getting bad about 6 months with no additive.

Nice offere, but W921 is right. Their is a reason the preppers all run diesel generators, trucks etc. You can store diesel for 10 years and it will be exactly the same as the day you put it in the tank. Even gasoline, if it has no ethanol in it, will easily last a few years.

I'm mostly worried about some moisture that would have accumulated. I don't want to run it in my truck.

If I'm remembering right the water should be on top. So if your pump feeds from the bottom of the tank you should get no water until the last bit.
Maybe someone else can chime in on this in case I got it backwards?
Always better to store a fuel tank full. Get less condensation that way if stored outside.

Diesel is an oil, and floats on top of the water, I would run it through a filter or a chamie in a funnel, used to do that all the time refueling aircraft out of barrels.

Skim it for water, or run a filter, and, if you are still nervous add a little Hydroquinone (stabilizer) to treat it.

You cant skim the water off as it will be at the bottom of the tank.On our sailboat we have the diesel tank filtered and cleaned ever 2 years because we use so little fuel when sailing i can get more than 2 years on a full tank.

If there is ANY Bio Diesel in it , it will have separated long ago (as little as 30 days).

If filtered it will be fine to use.

Do you remember when it was bought ? Summer ? Winter ? etc

Ya if it's bio diesel the tank could be full of moss by now. Toss a few goldfish in there

Good Tidy tanks have a large water and particulate filter on them for a very good reason. All vehicles that run diesel should also have water and particulate filters on them. With proper filtration and keeping the tanks full, not using Bio-diesel in stuff that will sit for long periods, you should have zero issues with keeping diesel for decades. It does not break down.
