Abstract: A fluid container for transporting, diluting, and dispensing a motor vehicle fluid, comprising an outer wall and a fluid chamber disposed within the outer wall adapted to hold liquids. The fluid container contains an additive concentrate stored within the fluid chamber which is adapted to be mixed with water to produce the motor vehicle fluid. The fluid container further has a selectively sealable opening which facilitates the delivery of water into the fluid chamber for mixing with the additive concentrate, and the dispensing of the resultant motor vehicle fluid. The outer wall has a transparent portion providing visibility into the fluid chamber and a calibrated dilution scale which allows a user to control the freezing point of the motor vehicle fluid by precisely diluting the motor vehicle fluid according to a plurality of dilution markers each representing a dilution level.
