What is the best oil for gears?
As a general rule high viscosity oils are best for low speed, loaded gears with a rough surface. Higher viscosity provides a thicker film, higher wear resistance, and less deformation of the gears as time goes on.
What is gear oil?
Gear oils are a complex subject, but their varied uses are one of the driving forces of modern industry and infrastructure. Gears make the world go round, but without lubricants they’d exist only in passing.
Why do oil emulsions need to be removed from gears?
Low emulsion formation. Gear oils, more than almost any other commonly used oil, need to emulsify water in order for it to be removed from the gears. This means that oils which easily emulsify with water, as opposed to separating from it, are highly undesirable.
What is universal gear oil?
These are usually termed as “universal” gear oils and while they can be used for industrial processes they often contain additives which can be detrimental to machinery.
Why is it important to separate oil from water?
By separating from water, instead of allowing the liquid to emulsify within it, gear oils can rapidly address the problem to keep corrosion and oil oxidation to a minimum. This is much more important for industrial applications than in automotive ones for obvious reasons.
How many grading systems are there for gear oil?
There are two separate grading systems for gear oils. For universal, or automotive, gear oils there are two sets of standards. Those which are destined for use in transmissions are graded according to SAE standards. You might, for instance, see 80W-90 gear oil or 75W-140 gear oils on the shelves.
Why is oil needed in gears?
Gears produce quite a bit of heat and friction as they work against each other, which means that an oil is pretty much necessary to avoid abrasive damage between the gears which will lead to the eventual degradation of a system.

What is the difference between GL-4 and GL-5 gear oil?
The main difference between GL-4 and GL-5 gear oils is the amount of EP additives. Sulphur/Phosphorus containing products are used as EP-additive. This additive has the purpose to prevent the occurrence of micro-welds on the gear flanks at the local high temperatures which prevail in EP circumstances (temperatures well in excess of 800℃!) GL-5 has roughly twice the amount of EP additives compared to GL-4, which is why it is often used in high-pressure circumstances such as in a front axle and rear axle differential.

Can you use GL-5 in a gearbox?
Therefore it is not recommended to use GL-5 in a gearbox unless the manufacturer allows this.

GL-5 is suitable for hypoid gear service under severe service and shock loads and not for use in a gearbox.
What is API GL-5?
API GL-5 – Intended for heavily loaded gear sets with high sliding forces such as hypoid differentials. GL-5 lubricants contain high levels of extreme-pressure additives to provide protection under boundary lubrication conditions. Common heavy duty applications include differentials in on-road and off-road trucks, differentials, final drives in Caterpillar scrapers, and differentials and planetaries in Euclid haul trucks. Some manual-shift transmissions can use GL-5, but typically should not be used in synchromesh-type transmissions, as the EP additives can be corrosive to yellow metals found in those transmission types. Limited-slip differentials also typically require a specific lubricant with a limited-slip additive.

What is universal tractor fluid?
Universal Tractor Fluids – This category goes by many specifications, such as John Deere J20C, Volvo WB-101, Case (IH) Hy-tran, Ford M2C-134A (and others), and is intended for axles and differentials in certain equipment that contain wet brakes. These fluids contain friction modifiers to reduce chatter in wet brakes, but should not be used in equipment that is designed for TO-4 fluids, as the friction modifiers that are used may negatively affect braking performance. Universal Tractor Fluids are also used in transmissions and hydraulics in many brands of equipment.
Can you substitute gear oil for another?
Different industry associations and different equipment manufacturers issue unique specifications. Most of the time, these specifications are not interchangeable. Substitutions of one type of gear oil for another can sometimes be done, but these substitutions can be tricky and you should use the guidance of a lubrication specialist to help you make the right decision.
Is gear oil the same as lubricant?
All gear lubricants are definitely not the same. There are differences in the additive technology used for lubricants for each specification, and just because one type of gear oil works well for one type of gear application, that doesn’t mean it will work well for all.
Can you use gear lubricant interchangeably?
Well, yes, they are all gear lubricants, but no, you can’t just use them interchangeably. Axles, differentials, final drives and other gear sets used in mobile equipment applications all require specific lubricants designed for the heavy loads and the sliding and rolling forces associated with the operation of gears.
