Can anybody tell me if Diamond SP 111 and diaQueen SP 111 are interchangeable. My Hyundai specifies Diamond SP 111 but I can only source diaQueen SP 111.
They're just brand names. DiaQueen used to be Mitsubishi's OE fluid in Japan, and Diamond used to be their OE fluid in export markets. Not much of a difference now.
You can use a multi-vehicle ATF meeting the SP-III requirement as well, if you have a hard time finding the stuff from Mitsu, or if it's ridiculously priced. Good luck!
Thanks for all the input. So far the only ATF that I could find in Johannesburg to meet the SP 111 requirements is the DiaQueen from Mitsubishi. So guess I will just go with it. Even Hyundai dont have SP111 they use Transmax Z.
