[QUOTE=rahula,Mar 9 2005, 12:08 PM] Right did a little more digging where to buy and what to buy for the rear diff and Castrol do indeed do two different synt oil. First is SAF-XJ but this is 75W140 but another one is SAF-XO and this is the right oil for us and is 75W90. Called my local BMW dealer and he does have the XJ in stock but no XO. Here is the link Castrol XO

Pain in the backside if you ask me trying to source these products unless I am doing something wrong. I just don't want to buy in bulk or pay

 

I'll go 50/50 for the XO stuff mate, just give me a shout. Who will you be buying from?

 

I'm going to try that number that Castrol gave to me. I'll give them a call and updtae this post later.

 

Wo-wo-wo lads.

Read the Castrol SAF-XO Link:
It states:
"Castrol SAF-XO is specially designed and fully approved by BMW for use in all BMW final drives fitted with conventional (non limited slip) differentials. Castrol SAF-XJ should be used for BMW final drives fitted with limited slip differentials."

Surely since the S2000 has a Limited Slip Differential then SAF-XO is not appropriate.

 

yes you are right but we don't have a BMW type clutch system LSD. It is a Torsen system and no need for friction modifiers. Therefore the XO is the right oil.

 

Update:

I phoned Castrol Classic Oils and they said they could supply SAF-XO in litre quantities. Its

We ought to do something in terms of an entry for the national lottery maybe (then we might be discussing which oils to use in red Italian cars instead)
