Grade Of Oil For The X4 Transfer Box?

[Guest Spike]

Simple question really... need to top the the transfer box on a mates M16x4 I have no idea what grade of oil to use as it's not covered in the Haynes manual and he doesn't have a handbook... What's recommended?

 

Cheers

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.
