Hi, just wondered what the concensus was on using any 75w90 synthetic gear oil in the diffs as castrol saf xo is very hard to get here in oz.
also any ideas on an alternative to castrol botfmb1 in the transfer box?

any help would be great

cheers

i have just (this weekend) changed all my dirveline oils, having looked around i opted to purchase from the deailer, with postage etc factored in there was very little proce difference. It may be worth ringing a uk dealer and asking them to post to you

thanks again

Just buy any quality 75/90 . If you can get Red Line brand thats more than a great gear oil for our RR.

I had to buy some transfer case oil as the dealer is the only source for it, I asked them what brand they use for gear oil.
Answer, they just buy whatever castrol, penzoil ect... by the drum , nothing fancy.

Thanks for that, I spoke to the dealer today, they had no diff oil in stock and told me the transfer is sealed for life ( we all know what that means ) and even the exchange transfers they fit come filled with oil??
spoke to castrol australia and they say that saf xo is made under licence to land rover and bmw and only delivered to them.

penrite is a good brand over here and they list a semi-synthetic 75w90 for the diff and a 75-80 for the transfer, I suppose a semi-synthetic will do as long as its all changed.

my rangey is at the age now where it needs good regular services and TLC so doing all the oils is no problem, been using penrite hpr 5-40 in the engine during summer and reckon its very good.

will check out the red line out.

cheers

hi again,

as i said previously i purchsed the oil form my local dealer (matfords of exeter on 01392 823923) only a couple of weeks ago, it was off the shelf. I changed the diff and transfer box fluids at the weekend and the stuff that came out of the transfer box was horrid!

Give them a call and im sure they will be happy to help you. If i can be of any further assitance let me know.

Hi tom, have you noticed a marked change in your gearbox since? I am thinking about having my gearbox oil changed - coming up to 90,000 miles now. Still runs fine with no probs, but pre-emptive strike now may avoid later costly damage methinks.

Thanks tom, could you tell me what the uk price was so I can gauge the shipping?

thanks

Is it safe to use compatible oils in the diff/transfer? If affirmative, what are the types and quantities?

For the differentials just use ANY good quality 75/90.

For the transfer case, ONLY use the correct oil specific to the transfer case, available only at the dealer.
Part#STC 4861 Its been a while but should still be the correct part #. It only takes 1 litre so not worth messing around with other stuff.

I just had my transfer case taking apart last week ( trying to track down a grinding noise) . There is synchromesh, clutches for the synchromesh and oil pump for the planetary gear set. For that reason the mechanic suggested only putting factory oil in it but mostly its because of the clutches for the synchromesh. You dont want a oil that that messes with the clutches.

I am sure you could find a transfer case that uses similar synchromesh/clutches and use that oil.... maybe the porsche cayenne .

Price wise. diff oil was £9.92 inc vat per litre and the transfer box oil was £9.20 inc vat per litre ( i bought 2 and used 1 and a bit to do a change) I do get some discount as my father in law is in the trade so may be slightly more!

Thanks for the help guys, will use penrite in the diffs and get the transfer oil from the dealers.

thanks again for all the great advice.

@ dolphinboy, yes it certainly seems smoother on th change, not sure the transefer box/diff oils made much differenc ebut the stuff that came out was not nice! cvar has covered 82k so plenty long enough on the oil in my opinion, when you consider on the 90's etc they get changed every 24k or so ( or yearly on mine) and they are far less complex.Well worth doing as preventitive maintenance.

Just changed diff and transfer case oils, the front diff takes about 0.9 litres, the transfer box 1 litre (phew!) but the rear diff swallowed more than 1.4 litres, not just one as stated! The diff oils were ok, yellow and clean, but the transfer case oil was very dirty! The 75W90 diff oil is 7EUR/l, but the transfer one is 26EUR/l!
