One Premix bottle (premix NOT included). Each bottle is 16oz. Makes it easier to measure what you are putting in the gas tank.
We recommend about 1/2 ounce per gallon of gas for cars with the oil metering system working, about 1 ounce per gallon if you do not have a metering system, and maybe 2 ounces per gallon for boosted engines.
