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.
What can I use instead of gear oil?
Substitutes for Gear Oil

What is the difference between gear oil and hypoid gear oil?
The term “hypoid” has more to do with the construction of engine gears than it does with oil. … Due to the higher pressure on gears as a result, the lubrication needed has to include ingredients to provide more protection for the gears. This special gear oil is designed not to deconstruct under higher pressure.

Which is better 75W90 or 80W90?
Ans: 75W90 is artificial and mostly better than 80W90, but it costs more. 75W90 has a better low-temperature viscosity and is good to run all over. If you’re in a warmer zone, using 75w90 will be more suitable than 80w90 for you.
Which is thicker 75W90 or 80W90?
SAE 75W-90 maintains a more consistent thickness, or viscosity, across a wide temperature range. It’s thicker when exposed to high heat and thinner under colder, wintry conditions than 80W-90.
What is SAE 80W90?
SAE class 80W90 transmission oils consist of high-quality base oils combined with an effective phosphorus-sulphur additive package. … 80W90 transmission oils are characterized by a high load carrying capacity, which enables them to be used in heavy machinery.
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.
What does GL-5 mean in gear oil?
A GL-5 grade oil has a very high rating for EP (Extreme Pressure) protection. EP gear oils contain additives that prevent metal surfaces from cold welding under the extreme pressure conditions found in situations where boundary lubrication prevails. … This is normal and acceptable in all steel gears.
Can I use hypoid gear oil?
Yes, as long as it meets the specification in the owner’s manual. However, for the best protection, it is best to use a gear oil specifically formulated for marine lower unit applications.
Can an axle leak grease?
Symptoms of a Bad CV Axle
A bad CV axle boot can loosen or tear, leaking grease onto the ground or the nearby parts like the tie rods, control arms, or ball joints.

Is hypoid gear oil the same as GL-5?
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 is Honda hypoid gear oil?
Honda Hypoid Gear Oil contains special shear-resistant additives that maintain viscosity under the most severe operating conditions. These and other special additives allow Honda Hypoid Gear Oil to meet the demanding requirements of the Honda Gold Wing and other shaft driven motorcycles and ATVs.
What is gl4 gear oil?
Phillips 66® Automotive Gear Oil GL-4 is a multipurpose, extreme-pressure, API GL-4 automotive gear lubricant specifically designed for use in select manual transmissions and in drive axles with spiral bevel gears or with hypoid gears operating under moderate speeds and loads.
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.
Is SAE 80 the same as 80w90?
Yes it is the same… close enough anyway. SAE 90 gear oil is equivalent to 50wt engine oil (SAE 80 = 30wt), so you could always dump that in instead if you want.
