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.
Does Mobil 1 gear oil have friction modifier?
Mobil 1 Synthetic Gear Lube 75W-140 LS contains special friction modifiers designed for limited slip type differentials. In most applications, the addition of special LS (limited slip) additives is not required.
Does Mobil 1 gear oil have limited slip additive?
Mobil Delvac™ 1 Gear Oil LS 75W-90 is a fully synthetic, limited-slip gear lubricant that been formulated from synthetic base oils and an advanced additive system.
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.
What are the disadvantages of synthetic oil?
| Advantages and Disadvantages of Synthetic Oil | |
|---|---|
| Advantages | Disadvantages |
| Resistant to oxidation and chemical degradation | More expensive |
| Withstands temperature extremes better (cold and hot) | Possible additive precipitation/separation |
| Flows better at cold temperatures | Slightly lower fuel economy at highway speed |
How long does synthetic gear oil last?
Another benefit of synthetic oils is that the range between oil changes can be extended (up to 30,000 miles for severe-duty applications, and 50,000 miles if the truck isn't used for off-roading or towing).
What is the difference between 75w90 and 75w140?
Both 75w90 and 75w140 have a similar density at lower temperatures. But 75w140 has a larger scale of viscosity – which implies that it works well in a wider temperature range. 75w140 is used for heavy towing because it is denser. 75w90 is used for occasional towing and normal use.
