Megaflow®AW HVI Hydraulic Oil

High VI Anti-wear HydraulicOil for Wide Temperature Ranges

Phillips 66®Megaflow AW HVI Hydraulic Oil is a high-quality, high viscosity index anti-wear hydraulic oil developed for use in industrial and mobile equipment operating in cold climates or in locations subject to wide variations in ambient temperatures. It meets the performance requirements of all major hydraulic pump manufacturers, and is recommended for use in all types of high-pressure, high-speed hydraulic pumps. It is particularly recommended for year-round use in mobile equipment such as bucket trucks, cranes and aerial lifts.
