Typically, a conventional gear oil will have a friction modifier added to it. This modification alters the properties of the fluid, which helps to increase the lubricity and prevent wear. However, some specialty gear oils do not contain this type of additive.

If you are using a conventional gear oil, you may be wondering if it can be used without friction modifiers. There are actually a few ways to do this. You can reduce the amount of additives in the oil, or you can use an alternative additive.

The first way to do this is to reduce the viscosity of the oil. This will reduce wear and allow the gears to run cooler. You can also add an anti-wear additive, such as ZDDP. This will reduce friction and provide a more aggressive level of protection. You can also use an iron sulfide barrier coating, which helps to protect the gears from corrosion and micro-welding.

Another way to eliminate chatter in a limited slip differential is to use a gear lube with a friction modifier. You can find friction modifier additives at most stores that sell gear lubes. It's important to make sure that you buy the right type of lube for the application. You should also consider how much friction you have to overcome to get the right friction coefficient. You will also need to adjust the temperature and load to keep the friction modifier from damaging the axle.

Using a limited slip gear lube with a friction modifier will help your car to run smoother and faster. You will also notice that your tires will last longer. You can also get better fuel economy with a high-performance gear lube.
