Low Density Means Lower Operating Costs

Aircraft hydraulic systems are filled to a specific volume level.
The weight of the fluid to achieve this volume is directly proportional to its density. A lower density fluid results in less weight carried by the aircraft.
Airlines can save money from lower fuel burn by using lower density fluids. The amount of money saved depends on the type and number of aircraft, number of flights, and the cost of fuel. Exxon HyJet IV-Aplus is the lowest density Type IV fluid commercially available.

Using HyJet IV-Aplus Results in Jet Fuel Savings Over Competitive Low and High Density Type IV Fluids
