GEARPLUS® SAE 80W-90 GL-4 Important .pdf file click to download

WARNING:
All modern gear oil available today in local retail outlets is GL-5 grade. GL-5 grade gear oil contains sulphur compounds that attack brass and bronze. BMW transmissions and final drives made before 1992 contain bushings and thrust washers made of these metals. Any brand of gear oil that is GL-5 rated will attack bushings and thrust washers. At Bench Mark Works, I use only GL-4 gear oil and we have it available for sale to our customers at the online parts store.

Pennzoil Specialty Gear Oil For Applications Requiring GL-4 Performance:

PENNZOIL® GEARPLUS® SAE 80W-90 GL-4 GEAR LUBRICANT is specially formulated to meet the unique requirements of API GL-4 service in manual transmissions and transaxles of passenger cars, light trucks and SUV’s. PENNZOIL® GEARPLUS® SAE 80W-90 GL-4 GEAR LUBRICANT is blended from select base stocks and additives that yield a lubricant of exacting quality. This product is compounded utilizing specialized extreme pressure chemistry that provides protection of gears and bearings without being corrosive to bronze components. It contains foam suppressants to prevent wear, which can be caused by lubricant foaming and aeration. Effective rust and corrosion inhibitors protect metal surfaces from the effects of water contamination from condensation and the operating environment. PENNZOIL® GEARPLUS® SAE 80W-90 GL-4 GEAR LUBRICANT resists the formation of varnish deposits on synchronizer components, thus assuring long, trouble-free operation.

PENNZOIL® GEARPLUS® SAE 80W-90 GL-4 gives the full protection of an SAE 90 under hard driving conditions while providing the flow characteristics of SAE 80W that are necessary during cold weather start-ups. This offers maximum lubrication and gear protection over a wide temperature range.

PENNZOIL® GEARPLUS® SAE 80W-90 GL-4 GEAR LUBRICANT is designed for manual transmissions and transaxles of both American and import vehicles. It is formulated to be compatible with “yellow metals”, such as bronze, found in synchronizers and other transmission componenets.

BENEFITS:

• Meets the performance requirements of API GL-4 Service
• Will not cause glazing of synchronizer components
• Excellent thermal stability
• Outstanding extreme pressure and antiwear protection
• Prevents rust and corrosion
• Inhibits foaming and aeration
