OVERVIEW

SUNOCO CHALLENGE PAO-EP SYNTHETIC GEAR LUBRICANTS are formulated with synthetic base stocks and fortified with select additive systems to enhance their exceptional performance. The PAO (Polyalphaolefin) base fluid used has outstanding oxidation and thermal stability, naturally high viscosity index and excellent low temperature pumpability and fluidity. The unique additive system used provides increased oxidation stability, extreme pressure properties, and maximum protection against wear, rust, corrosion and foaming.

FEATURES & BENEFITS

SUNOCO CHALLENGE PAO-EP SYNTHETIC GEAR LUBRICANTS are formulated with 100% synthetic base stocks and fortified with select additive systems to enhance their exceptional performance.  The synthetic base fluid used has outstanding oxidation and thermal stability, naturally high viscosity index and excellent low temperature pumpability and fluidity.  The unique additive system used provides increased oxidation stability, extreme-pressure properties, and maximum protection against wear, rust, corrosion, and foaming.

APPLICATIONS

SUNOCO CHALLENGE PAO-EP SYNTHETIC GEAR LUBRICANTS are recommended for use in all types of enclosed gearing as well as plain and rolling element bearings. These lubricants are ideal for heavily loaded low speed gears and bearings such as mine hoist gear reducers. They are particularly recommended for gearboxes which operate under excessively high temperatures where good quality conventional oils rapidly oxidize.  SUNOCO CHALLENGE PAO-EP SYNTHETIC GEAR LUBRICANTS are compatible with most seal materials, paints and plastics, including nitrile Buna N, neoprene, viton, teflon, polyethylene, polyurethane ether, fluorocarbon, polyacrylate, polysulfide, ethylene acrylic, epoxy, plastisol, PVC, acrylic paint and lacquer.
