Ok...i just did my CVT oils, feels great after the change but a few things to take note :
1) I went to a few service center....apparently they are unaware our Proton Inspira uses Mitsubishi Diaqueen CVT Fluid-J1 4 Liter Can (P/N: S0001401), some service center I went show me a Proton CVT Fluid in 1 liter packaging with different part number. Of course i went away and consulted my mechanic about this.
2) Some of you starts to thing....is it 4 liter or 6 liter?
According to mechanic, if you just unplug the bolt and
DRAIN the used oil out from the bottom of your gearbox, you will need a 4 liter can...which my mechanic show me by draining my used CVT fluid to an empty engine oil bottle which is 4 liter.
More CVT fluid is needed if you were to
FLUSH... it means they will use some machine to circulate the used oil and replace it with new oil therefore need almost double the amount because the CVT Fluid in your CVT Radiator will be flushed out and refilled with new ones too therefore you need more.
I dunno what method will the service center "flush" your CVT....so be careful of it's just draining then make sure they charge you the drain price not the flush price.
Therefore...if flush means 99% new fluid and drain means you still have some old fluid remaining .
3) The Mitsubishi Diaqueen CVT Fluid J1 is roughly around RM220 on the market out there...but in proton's list(based on proton-edar.com.my) it's around RM177.40 for 4 liters. So double confirm on the fluid they use...no harm asking right?
This is the one...the 4 liter can that i use to drain and change my CVT fluid :

The one some service center show me is as below (picture googled from internet)...
