Dear forumer.

I stopped going to Proton service center after ,my 2008 persona Auto warranty expired to save cost. I didn't care much to read what is good or bad for my car regarding motor oil and ATF oil before.
Recently, I started to do more research(because no more warranty hehe ) and I have read somewhere that for ATF oil, Persona must use SP III and not Dextron 3 which my current non proton SC is using.
I have used it for 10k kilometer already since April 2012. I am wondering if the above info regarding dextron 3 is correct. If it is, I'm planning to use Mitsubishi DiaQueen SP III. How many liter would I need? One spare part shop near my house selling 4 liter DiaQueen SP III for RM105. Is 4 liter enough? I'm worried now and requesting for advice from persona expert.
For motor oil I have stopped using semi-synthetic to Full synthetic 5w40 Eonos.

TQVM.
I'll buy 2 tin tomorrow and change. Anyone have experience with diaqueen sp III, I saw that their cap is a bit different. looks like once you open cannot close back. is it correct?
