Description
Hi-Tec Gear Oil 75W/90 GL-5 is a superior API GL-5 gear oil designed to provide:
- Excellent thermal stability
- Much Improved oil seal life
- Much Improved durability (gear surface life)
- Much Improved corrosion protection to yellow metals under both wet and dry conditions.
All of these improvements overcome the growing concerns of the gear manufacturers (OEMs – Original Equipment Manufacturers), vehicle and fleet owners relative to these performance areas when operating with the former generation of conventional hypoid extreme pressure drive train lubricants.
Hi-Tec Gear Oil 75W/90 GL-5 is specified for the lubrication of car, truck and tractor differentials and other final drives, transfer and steering gearboxes and manual transmissions. Special oxidation resistant paraffinic-base oils combined with high performance extreme pressure (EP) additives are formulated in Hi-Tec Gear Oil 75W/90 GL-5 to ensure long service life to transmission drive lines.
BENEFITS
Hi-Tec Gear Oil 75W/90 GL-5 avoids lubricant-related high temperature degradation problems of “cooked” transmission synchronisers and reduced oil flow to gear and bearings (due to obstructed oil passageways or filters) so that costly transmission failures associated with lubricant do not occur.
Hi-Tec Gear Oil 75W/90 GL-5 provides excellent long term protection against pitting fatigue, which is the life-limiting variable of a gear set. OEM’s recognise that lubricant protection against pitting is a very important design variable for long transmission life.
Corrosion protection is afforded by Hi-Tec Gear Oil 75W/90 GL-5 to copper alloys under both wet and dry conditions. The ‘stay-on’ properties of the high film strength Hi-Tec Gear Oil 75W/90 GL-5 effectively quietens transmission drive-line noise tendencies under conditions of low speed high torque, high speed low torque and shock loading.
Hi-Tec Gear Oil 75W/90 GL-5 avoids the natural development of foam in transmission service. Foam is undesirable because it promotes ineffective gear lubrication with resultant premature wear.
