Has anyone used Mitsubishi DiaQueen SPIII auto transmission fluid in their third gen? It's $115 for 4 litres at my local dealer and I was wondering if it's worth using as it's much more expensive than the usual Mitsubishi brand SPIII ATF.

That seems a bit funny, because as far as I can tell, DiaQueen is mitsubishi. Just search google images for it and you'll see what I mean.

i just got quoted $41 buck for 50 liters at Kelly's Mitsubishi next to Cardiff Toyota were i work,my question is im doing a flush next week how much of this stuff i am i gonna need
Thanks in advance.

:ninja:Sorry about my grammar my boss was in the office

You got quoted $41 for 5l or 50l. If you got quoted $41 for 50l then I am driving up there on a regular basis to by it as the 60l drums, which I go through about 2 or 3 a month are just over $400 each

As for the OP question, just use the std SPIII, there is no advantage in the transmission with the DiaQueen, in the trans case and diff by all means use the proper DiaQueen or even in just the diff as that is an LSD and is what DiaQueen is made for, but in the trans IMO is a waste of money given to do a proper flush you wont get much change out of 12l of fluid if done properly. The std dump and refill is 5.5l and then flush and top up post dumping and refilling

lol sorry i meant 5L so 12L should do me right for the flush.

Thanks again :) i love this Forum member's are very helpfully, glad to be a part of this Club people always ask me what the meaning of that AMC on your car
i just say oh its the Australian Magna Club. :)

Went back to the Mitsubishi dealer today to ask why the Diaqueen was so expensive. It turns out it's not Diaqueen SPIII after all. They mistakenly quoted for the ATF for the 6-speed auto Outlander!!!
