The weight of a gallon of water is about 8.34 pounds at 17 degrees Celsius. At different temperatures, the weight will be different. This is in Imperial measurements, where an Imperial gallon is equal to 4.54609 liters.
4.2 pounds at 60 degrees F. 4.2 pounds at 60 degrees F.

The weight can vary. Heavy oil weighs more than light oil. To determine the weight, we need to know the density of the oil, which is given as degrees API. Density in pounds per gallon = 141.5/(131.5 + API) *62.4 So a heavy oil. (10 degrees API for example) , has a density of 62.4 pounds per gallon, and one gallon weighs 62.4 pounds. A medium weight oil (30 degrees API for example) has a density of 54.7 pounds per gallon and one gallon weights 54.7 pounds. A light weight oil (50 degrees API for example) has a density of 48.6 pounds per gallon and one gallon weights 48.6 pounds. The density units of API stand for the American Petroleum Institute. I note that a density of 10 deg API is the same as the density of water, below 10 degrees, the oil will sink. I also note that if double the API density, I do not double the density of the oil as measured in pounds per gallon.
The weight of fresh water is largely dependent on its temperature. A US gallon of fresh water weighs about 8.328676 pounds at 70 degrees F.
