There's really no "best" per se. You just need to make sure either what you use has an additive in it, which most synthetics these days will, or to use an additive for the LSD.

Ok, thanks. Reason I was asking is because my rear axle seals and both pinion seals blew out within two years of the gear swap. The shop that did the job replaced the seals under warranty, but offered no clue as to what might have caused the seals to fail. I just want to make sure Iím using the correct oil. Iíve had a really bad experience with this shop, and I have no faith in what they tell me. The front pinion is leaking again after only about three weeks.

I recall that some diff lockers specifically recommend against synthetic fluid. Maybe someone on here can add the details I am missing.
