Need opinion on Rear Diff. oil

[Datsrboi]

Need opinion on Rear Differential oil. My friend recommended LE (Lubrication Engineers)' Duolec 1605 Gear Lubricant. I have been searching but no one seem to be using this on here. I was told some oil company that did the study said when compared to amsoil and other junk, LE was like taffy almost..

Was wondering if anyone use this stuff? I need to change mine. Its a NA LSD rear with 260K miles.... Never changed by the last owner and I just did a 1JZ swap.

Try to find some posts made by jdub. He has all kinds of knowledge on this subject. He may even have threads started about it if you'll look at his public profile, you can see if he does or not.

I use RedLine and it's always worked perfectly.

That's because Jay is a smart hillbilly

Ford 75W-90 (you have to add Ford friction modifier) or the Red Line 75W-90 (already contains the modifier) Jay is using above.

Ford non synthetic 75w-90 and the ford friction modifier xl3. The label on the ford non-synthetic lube even tells you to add the modifier. Did mine about 3000 miles ago and no issues. The job including a pump cost me about $20.. Damn cheap for a supra.
