Same bro, my friend mechanic at Nissan Tan Chong, but he bought Vios lol.. he recommend to change at 30k.
Don't want to risk it, haha.. just want to have a proper maintenance only.

around how much to change the cvt oil?

almost never seen any Vios J on the road, nobody is buying the J spec?

Full synthetic oil and using Techron Concentrate Plus??

My best is 485km..

100% city driving..

Pump caltex techron or Petronas or other ron 95?

Using full synthetic oil and additive?

Always long distance yeah?
Mine 3 years also but 38k 

I reflashed my ECU in Toyota SC for a better throttle response also good fc fortunately.

Just serviced my new vios 1000km.. saw this in the sheet.. Isn't it service aircon at 30k too soon? I heard it alone cost almost 300. Anyone skipped? Or if skip later if touch wood got problem, will kene "no service following their recommendation so no warranty" reason?

30k compulsory do aircon service feels like sangat cekik darah leh... I don't recall my Myvi doing this at all, 60k+ milage, just changing the cabin filter few times only...
O
Drag until 60k, then next service shall be 120k? Or follow same 90k? Lol

Anyone with 2019/2020 Vios G spec changed their tyres from the original size (195/50R16) to a slightly bigger  size but still use back the original 16inch rims?
what tyre size did you change to? does 205/50R16 fit?

Any owner here installed rear dash cam?
Compatible with our stock HU?
Car model 2017 E spec.

not sure though.. because SA quoted my next svc job included with fuel pump replacement, hence I am searching opinion here.
But replace fuel pump on the 4 years old car, is like, erm, that is new car, does the fuel pump need to be replaced so soon?
Any vios owner can provide some feedback or thought?

thanks.

wow bro.. yours 100k already? Mine only 52k, MCO time, the car very less driven. lol.. 
You mean those plastic joint like the door trim etc?
You sent car outside workshop to service already?
Haih, thats why, the SC quote fuel pump replacement for next svc, I was like, is it too soon to replace that part? maybe at least my mileage cecah 100k first? haha..

Hey guys, for those who buy the latest version vios (2019 to current), i am wondering what is your km per liter? so far my one is 12.6 km per liter now since just got the car.

You mean Denso Iridium IK20?  May I know how long have you been using IK20?  I only heard it might cause combustion deposit due to "too cold" but no sure IK20 will be consider as too cold or fine?  So far have you check your IK20 plug during service?
