What gear oil do I use in a limited slip differential?
Differential Oil By The Numbers Yukon recommends non-synthetic 80W-90 GL-5 gear oil in all differentials.
What kind of differential fluid do I need?
Use the highest-quality gear oil you can afford to fill the differential. The weight and capacity will be listed in your owner’s manual; your differential will usually hold as much as 3 quarts. Be sure to read that manual, though, because some limited-slip differentials require a secondary friction-modifying additive.
Do I need limited-slip additive?
Limited-Slip Differentials The MOPAR Limited Slip Additive should be added to the gear lubricant whenever a fluid change is made to an axle equipped with a Limited Slip Differential. 2500/3500 Model axles DO NOT REQUIRE any limited slip oil additive (friction modifiers).
What does Positraction additive do?
It’s only used on clutch type limited slip differentials. Posi additive is to make posis quiet. It actually helps them slip, so it won’t help a worn out posi & will probably hasten its demise.
Which grade of oil is used in differential?
Automotive differential uses hypoid gears exposed to severe operating conditions and it is applied with impact load in driving. Therefore, API GL-4 or 5 single-grade gear oil designed to maintain high viscosity at extreme pressure is used.
Is transmission fluid the same as differential fluid?
Differential oil contained in its own housing is sometimes referred to as gear oil. It is thicker than engine and transmission oil and designed to perform under the high pressure of gears mashing together. The gear oil splashes throughout the housing, lubricating gears, bearings, and clutch packs.
Do I need additive in my differential?
As long as you are running a full synthetic gear oil that the bottle says it has the friction modifier in it, then you don’t need to add anything else.
What does diff friction modifier do?
Friction modifiers are deployed to prevent wear on metal surfaces. Mostly used in transmission fluids and engine oils, these additives help slow down wear and increase fuel economy.
