API Category GL-3 (inactive) designates the type of service characteristic of manual transmissions and spiral-bevel axles operating under mild to moderate to severe conditions of speed and load. These oils may be used in selected manual transmission and transaxle applications.
What is MIL PRF 2105E?
MIL-PRF-2105E this specification released in 1995 combines the performance requirements of its predecessor (MIL-L-2105D) and API MT-1. It also adds the stringent oil seal compatibility and thermal durability test requirements under API MT-1. MIL-PRF-2105E has been re-written as SAE Standard J2360.
How do I choose a lubricating oil for my gearbox?
- Gearbox type: dimensions, the metal from which the teeth are made, sliding properties and gear ratio, open or closed casing, etc.
- Operating conditions: depending on the load, vibration and shock levels, anti-wear and extreme pressure properties determine the choice of lubricant.
What is gear oil used for?
Gear oil is a lubricant designed for use in transmissions, manual gearboxes, differentials, transaxles and transfer cases in your car or truck. Gear oil helps your transmission run smoothly. More importantly, it helps protect critical internal components in your car's gear systems from wear and heat damage.
Can you use GL-5 gear oil instead of GL4?
Yes, you can use GL-5 gear oil instead of GL-4. The most important fact here is the API GL rating.
What does GL-4 mean in gear oil?
hypoid
Can you mix GL4 and GL5?
No, GL-4 and GL-5 are designed for different uses. GL-5 does NOT replace GL-4.
What is a GL-5 gear oil?
DESCRIPTION. GL-5 Heavy Duty Gear Oil is an extreme pressure, multi-purpose, automotive gear lubricant. Excellent performance for differentials operating under high speed, low torque; and low speed, high torque conditions. It meets SAE, military and commercial specs.
What is 80w140 gear oil used for?
Q8 Synthetic Gear Oil 80W-140 is a heavy duty driveline product that can be used in manual transmissions, axles and final drives or differentials, especially those having hypoid gears.
What is 80w140?
The 80W90 and 80W140 are high performance SEMI-SYNTHETIC GEAR OILS with ANTI- FRICTION TREATMENT. They provide superior lubricity which means less wear caused by friction and improved gear protection at extreme temperatures.
Is 80w90 thicker than 80w140?
The higher the number, the thicker the oil. First number is cold and the second number is hot. Since 140 is higher than 90 its also thicker when hot.
