I search So i purchased some gear oil 75w 90 severe gear but I have VLSD so do i need any special additive to include as well as the oil or is it the same as having a no VLSD?

 

No additives needed.

 

Yep... what he said.. no additives. The part of the differential that uses the viscous fluid is a sealed unit called the viscous coupling. It resides inside the differential and the fluid inside does not mix with the gear oil that you fill your differential with. The gear oil in the differential just lubricates all the gears and moving parts inside the differential housing.

I run that same Amsoil in my rear diff and haven't had any problems with it yet.... knock on wood.

 

The Severe Gear is one of the best gear oils available for the diff. It's fine on its own.

 

Thank you gents

 

where is the cheapest place to buy the amsoil for trans and diff??

 

From an Amsoil dealer who hooks up his Driver brothers. (and sisters)
