lucas oils response to gear lube question.

I asked Lucas oils about adding friction modifiers to their dino 80/90 gear oil for a limited slip diff. This was their response ...what do you think?

Our 80w/90 has a friction modifier package already in the formula. I would
also use some of the Heavy Duty Oil Stabilizer in with the gear oil around
10% of the capacity. The Oil Stabilizer will keep the oil climbing up the
gear and keeping the oil temperature down in the differential.

 

Like the majority of the people with the mechanical LSD.... You can use whatever oil you want (recommended via manual) and it could already have the friction modifier in it....But until you put it in there and drive it around - chances are, you'll have to add more friction modifier especially if you run synthetics.

It's a *wait and see what happens* kinda deal.

 

There's a pretty long thread on here about the experiences people have had with various kinds (brands and syn/dino) of gear oils in their LSD. A good rule is to use dino with friction modifier. Although some have had success with synthetics, for most it's temporary and they end up chattering. I think one member was using Mobil 1 Delvac without issues. Can't remember if he added any friction modifier though. If I find the thread I'll post a link.
