Hello I just recently bought a cooper s 2002 and have been checking some parts of the car. I came to the power steering oil reservoir and noticed that there is no fluid in it at all... So I went only checking what it needed and found CHF11s oil, however my cap said ATF oil only. On yt saw a guy renewing his power steering oil and exact same car and build year with the cap of the reservoir saying CHF11s only. SO what should I do now refill with the CHF11s oil?
