Gear Oil is Lubricant that is made specifically for transmissions, transfer cases, and differentials in automobiles, trucks, and other machinery. Gars Lubricants provides a wide range of Gear Oil.

Introduction - Gear Oil

The purpose of Lubricating differentials, transmission, and transfer cases into machinery, automobiles, and trucks is fulfilled by Gear Oil.

The oil category known as gear oil has a high viscosity and mostly contains the chemical compound organosulfur. The 20% (percent) of the entire lubricant market is held by Gear Oils.

Gear oil is also known as gearbox oil sometimes, as the gearboxes which are industrially built and are expected to function in tough weather conditions of heat, pressure, water, dirt, etc. will wear and tear if not lubricated properly with gear oil to provide gears adequate protection.

Also, the hypoid bevel gears show a sliding action and so mostly all the lubricants for gears and gearboxes contain AW (Antiwear) Additives and EP (Extreme Pressure) Additives to cope up with such gears.

If not done properly or if oil is not changed on a timely basis, your equipment will face downtime and will also need to replace parts with more frequent oiling if the gear faces detrition.

To deal with such situations and to minimize negative chances of failure, Gars Lubricants offers a wide range of gear oils and lubricants specifically for each machinery/parts like gears and gearboxes to be specific.

Information about Gear Oil and Gearbox Oil:

Common additives include chemical compounds like sulfurized hydrocarbons and derivatives of dithiocarbamates.

Now, the EP (Extreme Pressure) Additives containing compounds of sulfur or phosphorus are bad and corrosive to yellow metals (copper, brass, etc) which are used in synchronizers and brushings where the GL-01 class of gear oil is applied and is used in which there is no EP Additive added in it.

The classification of gear oil or gearbox oil is done by the GL ratings given by API (American Petroleum Institute) and the more the GL rating, the less friction the gearbox suffers, or the more lubricant gears become with minimal contact between gear parts and more lubricity between them.

Currently, the modern and recent gearboxes mostly require a Gl rating of 04 (GL-04 Oil), and if there are separate differentials fitted then at that spot it requires oil with a rating of GL-05 because there is a high pressure between metal parts of separate differentials than gearboxes.

Viscosity is another important oil factor that is necessary to know about. The viscosity grades for engine oil and gear oil are different and the viscosity grades are different in scale for gear oils. The viscosity grade is also called viscometric and the gear oil viscometric is standardized by SAE (Society of Automotive Engineers) in SAE J306.

The greater the SAE number, the more vicious will be the oil. Now, it depends on your need for the viscosity to be higher or lower, which can benefit you, to know about it, kindly go through the next paragraph to get a clear perspective on it.

Higher Viscosity Gear Oils: Gearboxes that are slower in speed should use this type of gear oil because they will be able to resist intense pressure and the capacity of loads. It provides very well protection, from corrosion and wear and tear.

Lower Viscosity Gear Oils: Gearboxes that are higher in speed and with lower load comparatively, should use this type of gear oil because when the components are moving fast, it is capable to coat them much faster and better due to their thin films with a good cooling ability too.

SAE grade is used for automotive applications of gear oil and ISO grade is used for industrial applications of gear oil.

Also, multigrade gear oils are becoming more common because the gear oil does not reach the temperatures that of the motor oil but it gets heated up closely as when the car is driven, the reason being the shear friction experienced. Even better than mineral oils, synthetic gear oils are used which have a better capacity to tackle shear friction in vehicles.

What type of gear oil to choose and differences between gear oils?

While you are shopping and looking for gear oils in the market, you will see the conventional grades of gear oil after which you will purchase it.

Now, the most common grades for Gear Oil used are SAE Grades (for less-industrial or automotive) and ISO Grades (for industrial applications), these two are most common among all.

SAE Grade Gear Oils:

For all lubricants, SAE (Society of Automotive Engineers) Grades are used, but for gear oils, the SAE Grade numbered 60 or above 60 is only used. The greater the number, the more viscous property the oil holds.

ISO Grade Gear Oils:

Simply, the greater the grade will be, the more viscous the oil is. Its application is with industrial gear oils. Viscosity is measured in CentiStokes (cSt), and the ISO grades are given in such a way that it revolves much closely around the cSt number. For example, if the oil viscosity grade in cSt is 4.2, then the ISO Grade given to it is 4, likewise, for 320 cSt viscous oil, its ISO Grade is 320.

API Grade Gear Oil Categories:

Now, the GL rating by API (American Petroleum Institute) is how the underlying property or the base properties of the gear oil is measured. There is a GL rating from GL-1 to GL-6 given to the gear oil and API MT-1 grade of gear oil.

GL-1: Inactive or outdated oil rating category because they cannot cope up with extreme heat, pressure, or friction as they lack additives in it.

GL-2: Inactive or outdated oil rating category because they cannot cope up with extreme heat, pressure, or friction as they lack additives in it.

GL-3: Inactive or outdated oil rating category because they cannot cope up with extreme heat, pressure, or friction as they lack additives in it.

GL-4: Currently it's the most used oil category because they have a sufficient quantity of additives that can handle a good amount of pressure, load, and friction.

GL-5: This category of oil is capable of handling extreme load, pressure, and friction which protects even the hypoid gears. It contains even more additives than GL-4 grade gear oil has in it.

GL-6: This is an inactive category of gear oil currently. It was assigned for gears designed with a very high pinion offset and such designs mostly require an oil grade above GL-5 as it requires a grade score provided above that of Gl-5 and that is where GL-6 comes into place.

MT-1: This type of gear oil is used for devices/machines with "non-synchronized manual transmission" in it like heavy-duty trucks and buses are two of them. This category of gear oil protects from component wear, thermal degradation, and seal deterioration of oil which is not provided by gear oil with GL ratings of GL-4 and GL-5 and that is where the MT-1 category comes into place.

Now, the difference between gear oils provided by the company, is that of the quality of oil produced in an accurate proportion, which means to match the viscosity and other properties according to the rating label.

Q-3) How often will I need to change or apply the oiling inside the gearbox of the vehicle?

For Automatic gearboxes: Oil change range between 90,000 km to 150,000 km or 55,000 miles to 93,000 miles.

For Manual gearboxes: Oil change range between 40,000 km to 70,000 km or 25,000 miles to 43,000 miles.

Or after every gearbox repair or gearbox change.

Q-4) Why does my gearbox need gear oil lubrication?

Gearboxes are dependent on oil and lubrication for their proper functioning and to protect themselves.

The lubrication applied with oil provides them a cooling effect as the heat produced by friction is reduced at a huge scale and the wear and tear caused by friction is also reduced significantly by applying gear oil lubrication between gears.

This increases the lifespan and reduces the downtime of gearboxes drastically.

Q-5) Do gear oiling helps in increasing the efficiency of the work output of the machine?

Yes, the work loss caused due to friction and in heat is reduced a lot when lubrication is applied and therefore, increasing the work output for the input given, and the energy loss is reduced at a big scale. Also, the physical wear is reduced which in fact, reduces the downtime of the machine/gearbox.
