Diff Oil

Hi All,

After plenty of reading, I'm under the impression I need EP90 GL4 oil for the diffs on my TD5 90, and not GL5. Is this correct? Any local motor shops and Land Rover places only seem to stock GL5...

I've found a few on t'internet in 5L, does anyone know if they will be suitable and if they are any good?

Thanks!

GL5 will go in your diff's. Its the transfer box you don't want to put GL5 into.

Cheers Discomania... Should it be GL4 in the transfer box?

I remember a while back the Landy garage near me sent me away with some TRX stuff (not sure what it was) but then a guy in the garage I used to use told me it was the wrong stuff and that's why the transfer box died... (admitedly it was a second-hand disco box which went in, so could have been on it's way out)

The GL thing isnt so much of a rating, its the advances in technology (I believe) GL5 superseeded GL4.

EP90 is EP90.

The reason you dont want the GL5 in your Tbox is due to something in it damaging the brass bits. GL4 doesnt have this something.

If your only doing Diffs, stick with GL5, its easier to get your hands on.

Why does the landrover handbook say api gl5 for the transfer box then?

Later versions are OK with GL5 but I dunno when they changed the bushes away from phosphor-bronze.
You're safe with GL4 anyway.
Any decent motor factor (i.e. not Halfords) should stock it or be able to get it. I paid £14 for the last 5L can I bought.

mole valley farmers have it... if you live in the south west

I'm in YorkshireLand so will have to find someone a little more local!
