Unlike many oil applications, where slippery tends to be better, gears have different requirements depending on the system in question. What gets my goat is many of the motor factors where I am carry the Carlube range these days. I'm going to guess that GL stands for "gear lube" knowing the creativity of the oil industry Remember Shell advertising its SU gasoline? Eventually, the synchronizers will wear to the point that they no longer make contact with the other half of the cone, bottoming out before stopping the opposing gear. So while an API GL-5 gear oil can be utilized in an application where manual transmission fluid is recommended, there will be a tradeoff. I was concerned because a shop changed the gear oil while doing some other work, and gave me the extra oil, it was Valvoline GL-5 gear oil. By holding to the metal of the gears, it provides a thin foam which helps to prevent metal-on-metal contact. Dedicated gear oils on the other hand, are tailored specifically for industrial processes and contain a different set of additives and protectant compounds. Namespaces Article Talk.
Gear oil is a lubricant made specifically for transmissions, transfer cases, and differentials in Gearbox oils are classified by the American Petroleum Institute using GL ratings.
The higher an oil's For example, most modern gearboxes require a GL-4 oil, and separate differentials (where fitted) require a GL-5 oil.

While they. Synthetic transmission oil formulated with high-quality base oils and special additives package, provides good performance in a wide range of temperatures.
Sorry for yelling but elsewhere in these message boards, recommendations are made to use GL-5 gear oil instead of the VW specified GL
In doing some more research this afternoon, I've come across some owners who believe that their transmissions were ruined by use of GL-5!

Rust protection keeps the gears and other pieces of machinery from corroding as the oil goes through the system and also provide some protection from moisture which can make its way into the machinery. Fully synthetic gear oils are also used in many vehicles, and have a greater resistance to shear breakdown than mineral oils. But, the only thing that I would trust is if the Mfr.
common, or normal, for all GL-5 oils to claim they cover the API GL-4 requirements for gear oils. This is a true statement. Does that make them satisfactory for.
Of course you are not going to use straight weight. In many cases, there are also drawbacks to the additives, which means that making sure the correct additive package is used in the right situation is of paramount importance.
What happens if one uses a GL-4 oil in a GL-5 application? When a GL-5 gear oil is used in a manual transmission that contains synchronizers, you can expect to find two to four times as much copper in the used oil analysis report in comparison to a GL-4 oil.
Gl-5 or gl-4 gear oil
|All times are GMT It states in the specification of that oil it covers both GL-4 and GL-5, but I was under the impression that the two were completely separate and, whilst GL-4 can be used in a GL-5 box, it doesn't work the other way around?
The gears and synchronizers have seemingly conflicting requirements. Faster gears tend to heat up more than slower ones, but slower gears are often under higher loads which leads to more pressure and heat so remaining stable is extremely important. There are oils available for even the most extreme situations, so proper choice of lubricants in machinery is just a matter of finding the right oil for the system in question.
ISO grades are internationally agreed upon standards for oils used in industry.

Viscosity and Gears Unlike many oil applications, where slippery tends to be better, gears have different requirements depending on the system in question.
By holding to the metal of the gears, it provides a thin foam which helps to prevent metal-on-metal contact. Gear oils have a base grade which determines most of their qualities.

By supporting a circular economy of oil, that is to say a world where oil can be used again and again with minimal loss, it would seem that the old methods of dumping oil may soon be a thing of the past.
Foam Inhibition Because of the way that gear drives work, serious foam formation is a very real probability while things are in motion. Tweet 0. Can a GL-5 oil be used in a GL-4 application?
