Valvoline MaxLife Antifreeze/Coolant
The patented Alugard Plus technology used in Valvoline MaxLife allows this antifreeze to provide optimum engine cooling even when mixed with antifreeze of other colors. Instead of flushing all of the engine coolant, a car owner can top off their antifreeze with this formula and be confident that it wont cause excessive corrosion, which sometimes happens when mixing incompatible formulas. At a 50 percent dilution with water, Valvoline MaxLife has a boiling point of 265 degrees Fahrenheit and a freezing point of -34 degrees Fahrenheit. Valvoline uses yellow dye for this antifreeze, which they choose for color compatibility with other brands. Valvoline recommends this brand for use with both gasoline and diesel engines.
