Whats The Best Gearbox And Diff Oil To Use ?

Whats the best gearbox and diff oil to use in my 1996 R33 25t

I just got some Motul Gear 300 for GB & Gear FF for Diff...have not put it in yet but i heard its good & cheaper than Redline which is very good but very pricy

^^ I put Gear 300 in my gbox and diff. If you have an A-LSD then Gear 300 will wear your diff out, because it doesn't have friction modifiers for clutch type LSD.

However, the standard viscous LSD is a sealed unit and thus the diff oil does not need to be rated for LSD action.. hence I used Gear 300 throughout and can highly recommend it (anything that improves shift feel on a car with only 38000km on it has gotta be good!!)

im in the same boat, i have a 96 gtst with a lsd but dont know what oil to use in it.

The diff has no ovious markings or anything on it to identify it either, only that it is painted black.

yeah i only ever put motul into my cars

There is no best oil but any of the top brands would be fine (Redline,Motul,Castrol)

i once got told that if you have an active lsd you will have a liitle red light on your dash somewhere with A-LSD next to it?

yep, ALSD cars have a light in the middle of the tacho. if you don't have that it's fairly safe that you'll have a viscous LSD, unless the previous owner changed it.

for the LSD I'm not sure...

but for more my std rb25 box I just used Redline MT90...but the Motul would be my next choice. The Castrol SynTrans is also the goods.
