Curious, I went and filled up my tank today....(it holds 45 gallons). How much does diesel weigh per gallon? I know water is about 8 1/2 lbs a gallon, not sure about diesel but my guess is that it's heavier due to the additives and whatnot.

1 pint of water = 1 pound.

how do you get 8.5, when a gallon's 8 pints?

Jet fuel is 6.7 pounds per gallon so diesel should be close.

45 gallons of diesel fuel will weigh about 328 pounds. Depending on the season.

Diesel will weigh between 7 and 7.3 pounds per gallon.

Gasoline is about 6.6 lb per gallon.

The specific gravity of diesel is very close to that of water (1.0).

(Goggled at .80 to 1.08)

So, 8.5 X 45 = 382.5 pounds.

We just use 8 lbs per gallon -gas, diesel, or water- for rough estimates. We know it's going to be close but not exact, it does however give us a quick number to work with.

I have close to 400 pounds in my trunk! Dang.

Makes me wonder about the driving weight of my car...
