diff oil

[sookie]

Hey

What diff oils are you guys using in your gt4/caldina? how many L do I need?

the rear diff uses EP90 or 80w-90. 1.25 litres from memory

the front diff is part of the gearbox. use gear oil 75. 2.8 litres from memory

Should I be using regular mineral for the rear diff?

Front diff being combined with box. Same principle applies for automatic? so toyota dex 4 fluid?

No idea on model specific, so this is general info ONLY. Look up Mobil.com.au and check out lubematch, or Penrite.com.au and look for lube recommendations.

Whatever you use for the diff, ensure it is rated EP- or Extreme Pressure. This is an actual rating, first achieved by Mobil themselves in the 90's. Look out also if it is an LSD, as additive packages are altered to suit the metals found in LSD.

my comment refers to a manual gearbox and its integrated front diff. if you have an auto, then you need to check its model code and go from there.look on Toyota build plate. it will be A390 or something like that

the rear diffs are all the same and in any case the optional factory LSD uses the same EP oil as its a helical LSD which does not require the special LSD additives, as these are made for plate or cone type LSD's
