Not necessarily. Crude oil is the oil that comes from the reservoir. Usually there is some processing to remove water and gas from the oil before it is put in storage tanks. Heavy oil is generally black in color, but some of the lighter crudes can be the color of motor oil. Gas condensate (liquids coming from a rich gas) can be clear and be close to gasoline.

you do not have to mix your oil and gas in a metal can. the metal cans are generally a safety can designed for storage of fuel. try not to mix more fuel and oil than you can use in a 30 day period as the fuel starts to separate and will go bad

The process of natural gas is simple and similar to that of oil. Gas is extracted from the earth or the oceans by drilling from a well and then moved by pipeline or boats to a cleaning and processing plant and then to a gas grid or storage facility.
