For get the heavier and lighter than water thing, I know it depends on the viscosity of the oil. I am thinking diesel grade 15w 40 to be at 8-9 pounds per gal...??? any one know for sure, I need to move some in drums and want to make sure truck can carry it, thank you all much, Steve

Specific gravity of petroleum oil is 0.82(Machinery's Handbook).
Therefore oil should weigh 51.1 lbs per cubic foot.
(62.355 x 0.82)
1 US gallon = 0.1336806 cubic foot
So 1 gallon = 51 x 0.134 = 6.8 lbs.

Density of 15W40 is 0.888 g/cm3
1 gallon = 3785.41 cm3
1 lb (avoirdupoids) = 16 ounce = 453.592 g
Therefore weight of 1 gallon of fluid:
(0.888 g/cm3) * (3785.41 cm3/gal) / (453.592 g/lb) = 7.4107 lb/gal
