Full Version: Grade Of Oil For The X4 Transfer Box?
very special stuff. I'll have to look it up. I have some in the shed.
hmm i thought i had repied to this already 
.
anyway, you need 80W90 differential oil, syntethic would be good as it
absorbs the heat better and gives a little bit less transmission losses
than mineral oil.
or better yet, 75W140 - i use Castrol SAF-X.

p.s. don't mix the oils (if you meant that with "top it up"), but replace it
completely - you'll need a bit under 2 liters - 1.8 iirc.
hope this helps.

Don't fill the transfer box above the lower level mark on the dip stick.
Anymore than this and it can blow oil out the dipstick tube which then runs down onto the exhaust...and can catch fire.
