Diesel Fuel?

Anonymous-0 · Feb 18, 2011

Does the volume of diesel fuel change with the temperature? I had my barrel filled just before the big snowstorm hit the midwest. Haven't used any out of it. I came home yesterday after work and walked past the barrel and diesel fuel was leaking on the stand and ground. I got a ladder and checked the fill cap, fuel was within 1" of the top, the vent in the top of the tank had fuel drips hanging on it and a trail down the side of the tank. I got the tractor out and filled it up. No more leaks today. Was in the 20's when filled and mid 40's today. Would the fuel expand that much with the temp change? I have never seen this happen before. Thanks, wouldn't want the epa out here sniffing around. Thanks, No Name

It certainly does expand with increasing temperature. Tanks should never be filled full especially in cold weather, unless you"re going to use the fuel as soon as the bulk truck leaves.

Yup fuel and all liquids expand when they get warm.

I have seen many fuel tanks overflow when they warm up.

Try pumping your car tank full out of a underground tank in the spring when the ground is cold and it is 70 degrees out.

It will over flow if you fill it full if you don't burn some out.

My fuel man never fills my tanks clear full.

Absolutely. Especially gasoline. Here where wild temp. swings are not that uncommon, we always leave a few inches air space.

The volume of just about any fluid changes with temperature changes, fuel included. That's how "mercury" thermometers work. That's why they only put 40 gallons in a 55 gallon drum for shipments. You can google more information about this than anyone would probably ever want to know.

9.50x10^-4 /K for diesel

My rich uncle now decesed owned Wilson oil in indianapolis said many times there is a lot of extra cash in buying fuel cold and selling warm.

You bet. had that happen 2x with my gas barrel over the years.

That is why motor fuel LP tanks are not to be filled to more than 80%.

A lot of people feel cheated at the pumps too. Pumps usually have a sticker on them saying, volume is corrected to 15C. Depending on the temperature you could easily be short changed if you purchased a lot of fuel. It would be better if the price was adjusted to the temperature of the fuel. Dave

Most underground fuel tanks stay close to 65°F all year round so what you buy at the pump may vary a few degrees butit"s not nearly as variable as the air temperture.

I never liked buying fuel at a station with tanks above ground in the summer time, but loved them in the dead of winter. Temperature correction is 60 degrees. On a tanker load of 8200 gallons the correction a lot of the times is over 100 gallons

Approx 9-1/2 gallons expansion with a 500 gallon tank over 20F.

Your vent pipe is screwed into the tank...probably more than an inch deep...
if the fill cap was tight, a change of temp or atmospheric pressure could cause a spill if filled above the bottom of the Vent pipe..
