Can you use motor oil for gear oil?

You can put engine oil in the engine and gear oil in the gearbox. But do not mix them or use one in place of the other. Unless of course, your gearbox uses the same oil as the engine, then no problem. Many cars use the same type of oil for both applications.

Can engine oil be used as gear oil?

Gearbox oil has a higher viscosity than engine oil and this is because it better protects the gears, ensuring you have a smooth transition between them. … Therefore, you cannot use engine oil in your gearbox.

What can you use as a substitute for gear oil?

Substitutes for Gear Oil

  • Manual Transmission Fluid (MTF) An obvious substitute for the American Petroleum Industry Gear Lubricant (API GL-4 or GL-5) typically used in your vehicle is an appropriate MTF for your make and model. …
  • Automatic Transmission Fluid (ATF) …
  • Motor Oil.

Is gear oil and engine oil Same for bike?

No, gear oil is a 90 mono grade oil, while motor cycles use multi grade oil for engines, which is also a gear oil in smaller engines. Use your discretion.

How do I choose a lubricating oil for my gearbox?

After selecting the viscosity grade, the basic type of lubricant must be chosen. While there are many variations, gear lubricants can generally be placed into three categories: R & O, antiscuff and compounded. The gear lubricant type that best fits a given application will be determined by the operating conditions.

Is engine oil same as lubricant oil?

Motor oil, engine oil, or engine lubricant is any one of various substances that consist of base oils enhanced with various additives, particularly antiwear additives, detergents, dispersants, and, for multi-grade oils, viscosity index improvers. Motor oil is used for lubrication of internal combustion engines.

Can you use grease instead of gear oil?

Some amount of grease can be added to an oil-lubricated gearbox to reduce lubricant leakage or noise. … With this in mind, it would be acceptable to use an NLGI #00 grease in the application. Just be sure to check the operating temperature after the change, since it may increase a few degrees.

What is gear oil made of?

Transmission fluid, also called gear oil, ensures smooth functioning and extended life of transmissions, transfer cases and differentials in cars, trucks and other machinery. Like motor oil, they are composed of base oil (mineral, semi- or fully synthetic) and additives.

What can I substitute for power steering fluid?

Power Steering Substitutes

You can use your transmission oil, engine oil, axle oil, or hydraulic fluid as a replacement for power steering lubricant in an emergency. But remember that these substitutes can end up causing damage to your power steering system if they are used in high amounts.

How is gear oil different than motor oil?

Gear oil differs from motor oil. While many motorists may assume SAE 90 gear oil is thicker than SAE 40 or 50 motor oil, they are actually the same viscosity; the difference is in the additives. … To combat this extreme environment, extreme-pressure additives are incorporated into the oil.

Is gear oil thicker than engine oil?

The main thing you’ll notice about gear oil is its viscosity. It’s much thicker than motor oil, with an average motor oil being 5W/30 and the average gear oil being 75/90 (see this article for in depth explanation of oil viscosity index).

What kind of oil goes in a gearbox?

For example, most modern gearboxes require a GL-4 oil, and separate differentials (where fitted) require a GL-5 oil. While they take the same form, the viscosity grades for gear oils are on a different scale than the viscosity grades for an engine oil.

Does it matter what gearbox oil I use?

Higher viscosity provides a thicker film, higher wear resistance, and less deformation of the gears as time goes on. Low viscosity oils, on the other hand, are best for high speed systems with lower load. They provide a thinner film and better cooling to match the higher speed of the gearbox in question.

What is the thickest gear oil available?

Short answer: 85W140 is thicker.
