Oil vs. Water Density. Pure water is the reference point, so it has a specific gravity of 1.000. Salt is more dense than water, so seawater has a specific gravity of about 1.025, depending on the location. Crude oil density varies by location; light crude, such as that from Texas, measures at about 0.876, and heavier oils check in at 0.918.
