    Default weight of 1 gallon of diesel

    anybody know this. I always guess at 7 pounds/gallon. I was very close on weight the other day and almost out of fuel. Just wondering if anybody knows the accurate weight of diesel.

    The rule of thumb is 8# / gallon.

    #2 fuel oil (which I deliver) weighs approximately 7.2 pounds per gallon. Red dyed diesel fuel sometimes is rebranded as #2 fuel oil (heating oil) because the specs overlap. I assume the weight is very close.

    I was told 7.2 lbs. I know it's under 8 but figure on 8 lbs per gallon to be safe as Ridge said because the weight can change between summer and winter months and other factors that are above my head.

    Twi, water is 8.3 lbs :wink:

    During the summer, diesel will weigh between 6.951 (API 38) and 7.076 (API 35) pounds per gallon. Last winter, the diesel weighed around 7.206 (API 32) pounds per gallon.
    1 gallon of water equals 8.33 lbs.
    1 gallon of gasoline equals 5.8 to 6.5 lbs.
    1 gallon of ethanol equals 6.59 lbs.

    8 pounds as a general rule.. keeps the safety zone in there. If you are worrying about .2 pounds per gallon, you may want to load a tad less freight! :P

    I can hook up my BlueBerry to the newer meters. By knowing the temperature of the fuel, my BlueBerry calculates the API (specific gravity) and gives me the weight of the product with an accuracy of 5 milligrams.

    :P


    Then I come to find out that there can be a couple ton discrepancy between the documented unladen weight and the actual weight of a vehicle! :shock:

    If water weighs 8.2 lbs/gal, and oil floats on water, it has to be somewhere between 7-8.

    Thats my .02, which coincides with the general consesus here :lol:

    Ask and ye shall receive: 1 liter of air weighs about 1.3 grams. That's some light stuff.
