What is hypoid grease?

A hypoid gear oil is a lubricant that is designed to operate effectively with hypoid gear designs. Most gearboxes and differentials use hypoid gear designs and the lubricant must contain EP (extreme pressure) additives to prevent wear between the sliding surfaces of a hypoid gear mesh.

Is hypoid oil the same as gear oil?

Hypoid Oil Differences It’s a gearbox oil, just like others, but the ingredients are different. This type of gear oil is mixed with additives designed to increase its resistance to breakdown under high temperature and mechanical pressure produced by hypoid gearboxes.

What is hypoid gear oil SAE 90?

GEAR OIL HYPOID SAE 80W/90 is a high-pressure gear oil that can be used wherever very high levels of stress occur, such as in cardan joints, hypoid gears etc. GEAR OIL HYPOID SAE 80W/90 is used in motorbikes for which GL-5 gear oil is specified by the manufacturer.

What is 80W90 hypoid gear oil?

Gear Oil Hypoid 80W90 is a API GL-5 Gear Oil is designed to increase resistance to breakdown under high temperature and the mechanical pressure produced by hypoid gear boxes and universal joints.

Is hypoid gear oil the same as GL-5?

The main difference between GL-4 and GL-5 gear oils is the amount of EP additives. GL-4 is suitable for hypoid gear service when they are under severe service but are without shock loading. GL-5 is suitable for hypoid gear service under severe service and shock loads and not for use in a gearbox.

What can I use instead of 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.

Can you put grease in a rear end?

A rear differential transmits power from the transmission or transfer case to the wheels. Most differentials call for SAE 75w90 gear oil, however some heavy-duty and limited-slip differentials need SAE 75w140 gear oil. Consult your owner’s manual for the proper weight oil to use.

What is a hypoid rear axle?

Hypoid gearboxes are a type of spiral bevel gearbox, with the difference that hypoid gears have axes that are non-intersecting and not parallel. In other words, the axes of hypoid gears are offset from one another. In hypoid gears, the distance between the axes of the crown and pinion is known as the offset.

Is hypoid gear oil the same as GL 5?

What is a hypoid gear set?

A hypoid gear is a style of spiral bevel gear whose main variance is that the mating gears’ axes do not intersect. The hypoid gear is offset from the gear center, allowing unique configurations and a large diameter shaft. The teeth on a hypoid gear are helical, and the pitch surface is best described as a hyperboloid.

Which of the following gear lubricants is typically recommended for differentials that use hypoid type gears?

In differential applications that use hypoid gears, AMSOIL typically recommends one of the following: Severe Gear® 75W- 90 Synthetic Gear Lube (SVG), Severe Gear 75W-110 Synthetic Gear Lube (SVT), Severe Gear 75W-140 Synthetic Gear Lube (SVO), 80W-90 Synthetic Gear Lube (AGL), 75W-90 Long Life Synthetic Gear Lube (FGR) …

What kind of oil do you use in a hypoid differential?

This design is much more efficient, quieter, and allows for a higher torque pressure. However, this type of differential requires an oil (hypoid oil) that will withstand the higher pressures. When I asked my dealership about the Hypoid oil, they told me any 90 wt gear oil would be fine and that was all they had.

What is the difference between hypoid gear oil and synthetic oil?

The Hypoid gear oil comes with appearances like75W-90, 80W-90, 85W-140, etc. whereas synthetic oil comes as 5W-30, 10W-40, OW-20, etc. The Hypoid gear oil can run up to 50000 miles on average. On the other hand, synthetic oil can help to run the vehicle a maximum of 15000 miles on average.

What type of oil do you use in your differential?

However, this type of differential requires an oil (hypoid oil) that will withstand the higher pressures. When I asked my dealership about the Hypoid oil, they told me any 90 wt gear oil would be fine and that was all they had.

Is there a difference between hypoid gear oil and limslip?

This is likely not the case on your differential but I’d suggest talking to some enthusiasts of your specific vehicle to find out for sure. From what I can tell, Limslip oil is designed for vehicles with limited slip differentials, and thus has extra additives over a normal hypoid gear oil.
