Why not go with 75-90? You're in NY and it doesn't hurt to have the lower weight (cold) for the winter. Hot climate performance between the two is practically the same. Torsen type LSD like the one from the supra requires no special oil. Just the same fluid as the OEM GS unit. It's only when you get the clutch-type LSD (TRD) where you need a particular fluid with friction modifier in it.

BTW its royal purple, not blue

because the idiot at autozone told me 80-90 was the best option ..i now realize 75-90 is better .. and now the part is installed with this fliud.. last nite someone told me i needed royal purple because its needed for the lsd .. glad to hear its not

Never listen to the guys at autozone unless they specifically own a supra, and they work on their own cars. Unless you have a lot of power and your differential heats up very quickly, your application does not warrant the 80w-90 fluid.
Most people jump on the synthetic bandwagon because it's only a few bucks more than regular fluid.

I've been running the Valvoline 75W-90 synthetic for a year now in my 3.76 LSD. works very well. I changed the fluid after the first 1k mi. just as a precaution.

Where did you guys purchase the LSD? This is the final piece I'm missing.
