Is Thicker gear oil better?

Higher-viscosity gear oils offer thick films, better wear resistance and protection from corrosion, making them suited to slower gearboxes that operate under more intense pressures and loads. They also seal components better, affording longer change intervals.

What is SAE viscosity grade of oil?

What are the two SAE viscosity grades?

Two series of viscosity grades are defined in SAE J300: (a) those that contain the letter W and those that do not contain the letter W. Single-viscosity-grade oils (“single-grades”) with the letter W are defined by maximum low-temperature cranking and pumping viscosities and a minimum kinematic viscosity at 100°C.

What’s the difference between SAE and regular oil?

5. Is SAE The Same As Regular Oil? An SAE oil can be regular oil (conventional oil) or other types of engine oil (like synthetic motor oil). An SAE prefix simply means that the oil meets the SAE standard.

What is the viscosity of 5W oil?

Notice the different numbers in the viscosity ratings: “5W” and either “20” or “30”. The first number (5W) refers to the oil’s viscosity when cold, measured at 40°C (104°F). “5W” refers to the oil’s viscosity when cold, measured at 40°C (104°F).

What is the difference between 10W and 40?

Can you use thicker oil in hot weather?

In very cold weather, you may want to use a thinner hydraulic oil, because the cold thickens your oil. However, even if it is extremely hot, you should not use a thicker oil.

Can ISO 46 replace SAE oil?

You may notice that ISO 46 can replace both 15W and 20W SAE oils. This is because the ISO specifications are broad, and they overlap with SAE weights in some cases. If your tractor or truck calls for 20W hydraulic oil, it may be best to use the thicker ISO 68 in hot temperatures and thinner ISO 46 in cold weather.

What type of oil is used in a manual shift truck?

Universal Tractor Fluids are also used in transmissions and hydraulics in many brands of equipment. SAE 50 Engine Oil – While not strictly a “gear oil,” this type of lubricant is often the recommended lubricant for some manual-shift truck transmissions.

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.
