Abstract: A measuring, metering, and mixing can, particularly for gasoline and oil, including a gasoline container with filler cap and spout; and oil container with filler cap; visual type gauges for each container; and a plunger-cylinder metering unit for withdrawing a selected amount of oil from the oil container and injecting the same into the gasoline can for producing an oil-gasoline mixture. The visual gauge on the gasoline container and the visual gauge on the oil container permit the metering of an exact amount of oil, dependent upon the amount of gasoline within the gasoline container for a precise ratio of oil-gasoline in the mixture. A hinged cover on the can protects the metering equipment during periods of non-use.
