Mine is defo square drive, I'll double check tonight if it's the right one and take a pic

 

For the diff oil, I used Ravenol MDL from Blauparts.com. Works great and no more shuddering. It is Jaguar approved. In fact, I buy oil for my Porsche, Range Rover and Jag there. Great service, prices and shipping..

What good oil for my 2007 car ?

 

Ford spec MC2 192a.

 

Thank's but is M2C not MC2 ? I don't have e-diff on xkr 2007 ?
This oil is correct ,

 

Interesting 75-90w was intinally recommended on the ls Lincoln Gen 2 diff (which is the xk/r 4.2 open diff) then somewhere along the way they changed their recommendation to a 75-140w so obviously it's applicable to our own jaguar diff .

 

Yes it's curious, XKR 2007 don't have DSL no? 75-90W is for not DSL and 75-140 is for DSL. I don't understand why the spec are changed. It's difficult have information.

 

Neither the xk or xkr have limited slip differential your correct it's confusing as 75-140w is recommended for LSD .

It was believed that switching from 75-90w to a 75-140w would extend the life of the differential so I guess thats why there was a change to the recommendations .

On a side note I'm currently running a 2005 ford thunderbird 3.58 diff and upon installation I filled it with a 75-140w however on two occasiond I have topped it up with a 75-90w .

 

i don't know what the good oil can i put in my xkr ?

 

apologies... a dyslexic moment without my glasses... please see

I believe either is fine one is going to be a lower friction and the revised recommendation 75-140w is meant to prolong the life of the differential.

 

Thank's for all. I go buying Motorcraft oil 75-140.

 

it's difficult buying Motorcraft from France because there is big shipping!!
i've buying Liqui Moly (GL5) LS SAE 75W-140 VS Hypoid is ok to Ford WSL M2C-192A.
Thank's
