80W-90 LS GEAR OILS PETROFLO SAE 80W-90 LS GL-5 GEAR OIL exceeds the latest requirements of gear manufacturers requiring API GL-5 lubricants. It is recommended for use in limited slip and conventional differentials of cars, pickup trucks and sports utility vehicles. It is designed to reduce or eliminate "chatter" that can sometimes occur in limited slip differentials. High-speed shock loads, higher torque requirements for extended periods of time and high operating temperatures call for heavy-duty quality lubricants of this caliber. PETROFLO SAE 80W-90 LS GL-5 GEAR OIL is fortified with extreme pressure additives for tough protection under severe operating conditions. It contains rust and corrosion inhibitors to protect against the effects of moisture from condensation. Effective foam inhibitors prevent foaming and aeration that can lead to premature wear. PETROFLO SAE 80W-90 LS GL-5 GEAR OIL is recommended for use in hypoid or spiral bevel gear differentials and manual transmissions where an GL-5 lubricant and an SAE 80W, 90 or 80W-90 viscosity grade is specified. In addition, PETROFLO SAE 80W-90 LS GL-5 GEAR OIL is fully formulated for all limited slip differentials. It may be used as a makeup or refill fluid, even for rebuilt limited slip units and is designed for all high performance hypoid axles of cars, pickup trucks, sports utility vehicles as well as sports, police and racing cars. It is also recommended for conventional differentials.
