as you know, I just changed my PS pump and I want to refill some good fluid. what do you guys use?

I used to have the
Jaguar OEM Hydralic System Mineral Oil

but some say not necessary.



also found

PENTOSIN

 

I think most of us use dexron III atf.

 

I am about to put Mobil Dexron III ATF

 

Any good quality Dexron111 fluid is applicable.

On no account use the HSMO fluid in these, it's not compatible.
That fluid was for earlier XJ40/XJS cars.

I find that using a bottle of LUCAS PS Revival fluid goes well in these mixed with Dexron111
