Gear Oil/Tranny oil

[Steve8v92]

I have a 92 4 runner 3.0L 4x4
Need to change the transfer, diffs and tranny oil/filter
Can someone recommend a good brand of oil to use.
I planned on adding a 1/4 bottle of lucas oil additive to each diff.

Anyone recommend synthetic red line or any stuff like that?

I use motul. Its a performance oil.

Red Line, Motul, or Amsoil; depending on what you can get your hands on.

IMO they're all "more than good enough", if you stay on top of maintenance.

(check/replace if you do any forging, as well as periodically keep an eye on the levels and check for shavings)
