LSD Oil

[HMNGSupraMKIII]

What kind of oil do you guys recommend for my car, It's a 1989 Supra Turbo with lsd. What kind and how much do i need. This is my first time changing the differential oil so kind of nooby. THanks

75w or 80w90 and ford friction modifier.

What is a ford friction modifier?

 

[jdub]

Hvyman is referring to LSD oil made by Ford...it is a good choice for a LSD with a lot of miles on it. It is straight differential oil - an LSD requires some slip to function correctly. Ford sells a friction modifier for that purpose. Some LSD oils already have the modifier included in the formula...Redline comes to mind

Oh, and just in case you hadn't already done this, my best two pieces of advice here:

-Remove the "fill" bolt first, and...
-Use a 6-point socket.

Trust me on this. Nobody likes to nearly strip the head on the fill bolt, with an empty diff.

Ok thanks. I will be doing my lsd oil change within the next couple of days.
