Is synthetic gear oil better than regular gear oil?
Synthetic lubricants have a lower friction coefficient in a gearbox, better film strength and a better relationship between viscosity and temperature (viscosity index, VI). This indicates synthetic lubricants can be used at lower viscosity grades and lower temperatures.
What is 75w90 gear oil used for?
The 75W-90 gear oil is used under extreme pressure conditions and is recommended for limited-slip differentials and for use in colder climates. Used in heavy duty manual transmissions, final drives and axles, high temperatures will not effect the heavy film left by this oil.
Does synthetic gear oil last longer?
Synthetic oils have better resistance to aging and high temperatures and a longer service life than mineral oils.
Is there a difference in gear 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.
Can I use 75w90 synthetic instead of 80w90?
Ans: Yes, you can mix 75w90 with 80w90.
Can I use 80W-90 instead of 75w85?
Very close viscosity. Most diffs were designed with 75W-90 in mind. Going to 75W-85 was a fuel-economy-boosting endeavor. AMSOIL Severe Gear 75W-90 is designed to replace, 75W-90, 75W-85, 80W-90, SAE 80 or SAE 90 gear oils. It can replace any of these with no worries or risk.
What is synthetic gear oil?
Synthetic gear oils Created from polyalphaolefin and additives, these oils are primarily used for extreme machine conditions. Whether it’s super low or super high temperatures, synthetic gear oils are the best choice when you’re looking at conditions which other oils simply won’t function in.
Is 75W90 better than 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.

What is 90W gear oil?
90W Gear Oil, 5 Gallons Recommended for any application that requires straight mineral oil, such as universal joints, closed gears, steering gears, and more, this 90W gear oil can handle it all. With no excessive additives, this oil includes an anti-foaming agent to keep it lasting longer while in storage.
What do the numbers in gear oil mean?
The number indicates a level of the oil viscosity at a particular temperature. The higher the grade number, the higher the oil viscosity. Viscosity of gear oils designated with a number only without the letter “W” (SAE 80, SAE 90, SAE 140 etc.) was specified at the temperature 212°F (100°C).
