Volume Correction Factor (VCF): The volume correction factor is the factor used to convert the volume at observed temperature to obtain the volume of the cargo at standard temperature.

To comply with ASTM D5002, light crudes can be readily measured without heating treatment directly on a density meter; measurements can be undertaken between 15 and 35 °C, and the integrated temperature compensation ing to API tables transforms the density or specific gravity to either 15 °C or 60 °F.

The density of all oils decreased as temperatures increased. There was some variation between oils in the temperature coefficients of the change in density. The density differentials between oil and water and their temperature coefficients varied markedly between the different oils.

Density is directly proportional to pressure because high pressure results in compression of a gas, meaning that you have a chunk of gas in a less amount of space, meaning higher density. Density is inversely proportional to temperature because increasing temperature always causes the decompression of particles.

The density of fuel should be corrected using an appropriate temperature correction factor obtained from ASTM Petroleum Table 54B or equivalent or computer software incorporating these tables or the formula: Corrected density = Density (in the air) at 150C X [1- {(T0C – 150C) X 0.00065}], where T0C is the temperature ...

What you can do is mix the oil with something else. A solution (two or more things mixed together) of oil plus another ingredient would increase the density of the oil. This is the same reason that salt water is heavier than fresh water, the weight of the salt is added to that of the water, making it more dense.

Volume Correction Factor or "VCF" means the coefficient of expansion for petroleum liquids at a given temperature and density. The product of the petroleum liquid volume, and the volume correction factor, equals the liquid volume at a standard temperature of either 60 degrees F or 15 degrees C.
