wah pk47.how can ur car get better fuel consumption ah?mine become worse.engine sound also get noisier.more "garang" lh!(dunno good thing or bad thing..ha3).but performance i think quite ok.i m using mobil esso 5000.
I not very sure how come is work for my ride, maybe my car still new cos i brought it last year dec, a 2003 altezza. :)
This morning try to pump back ron97, RM60 bucks less than 30 litter of fuel. :( Very big different compare with ron95. Please see my 'feel' below. :)
Ron97 - Ron95
1) Better power on low rpm - Smooth, when vvti kick-in can feel more power
2) Can't feel any more 'toque' when high rmp - Getting more 'toque' and power keep going
3) Engine more quite - Engine sound more 'garang'
4) high fuel consumption - Low fuel consumption
5) fuel not fully burn, can smell petrol - No petrol smell
pls remember to provide ur review here... :)i pumped 60 bucks of RON95 this morning from esso. so far, my tezza is fine with it. just a bit sluggish and lack of power when i push the car with 3rd gear at 6k rpm. engine noise, not much difference. overall, not much difference except power. fuel consumption not yet test. need to wait till i finish this tank first. normally, i get 330km - 360km for 33.33 Liters on RON97. This morning, i also pump in 33.33 Liters. Hope the mileage will be better or not, same with RON97.
Uh you sure?I not very sure how come is work for my ride, maybe my car still new cos i brought it last year dec, a 2003 altezza. :)

weird.. ain't it suposed to be the opposite ... does SXE10's ecu smart enuf to self-adjust itself to adapt to the new RON value ??
Yes! u r right. SXE10's ecu will automatic adjust the fuel and airflow output and input to keep the engine performance, because the throtlet body is electronic control. :)

Uh you sure?
It's actually the reverse for my car, especially on number 5. My car especially engine bay smells of petrol when I'm on ron95.
Maybe i change alot of electronic devices and air filter kua.... :)
bro, normally the autobox cannot change to 2nd gear in manual mode if the car is not in its optimal tempreture.. summore in genting :rolleyes:This is my experience 1st time climbing up genting with a tank of ron95:
on the way getting up genting, everything looks ok. no significant power lost. But the 2nd day when i plan to back home, after i started the engine and drive towards carpark exit. I feel my car was seriously underpower, and it not allowed me to change to 2nd gear when i use manual mode. After a few minutes, the car only back to normal.
As for the last time i went genting and still using ron97, underpower also happened when the engine still cold. But not as serious as this...
Btw, i'm using SHELL ron95
no bro, i get bad FC on ron97! after used 3 tanks ron95...:stupid:i also get a bad FC and lack of power with RON95. 33.33L RON95 = 320km, 33.33L RON97 = 350km. but i'm sticking to RON95 for a while. maybe in oct will decide which RON to use.
seems getting better after the 3rd tank of ron97 now..I just pumped back 3/4 tank of ron97, feeling nice....
:hmmmm: huh ??? ....seems getting better after the 3rd tank of ron97 now..
me too sticking with ron97.i pump ron97 esso today cos going up genting. darn... it feel good. the car pickup is great. darn... looks like i wanna stick to Ron97 now.
It is advisable not to use RON 95 for Altezza at all..any problem running long term wit ron 95?
Zeus83,im using 3SGTE, i feel no power diff with RON95:hmmmm:
You are right on the nose Mike...I would have ask the same question like you too. Why spend money on an ECU management system and pump low grade petrol in my car. The reason I spend money on mods like electronic management system, headers, air filters etc... is too extract more torque and increase bhp on my car. Why would I defeat all this by pumping in lower grade petrol.Yong_5290,
u were saying perhaps can use management to retard timing.
i'd say the 'idea' is a bit naive. yes, of course u can use management to control that, BUT
i don't think that even worth the management. if i were to have management in my car,
i'd use it for other better purpose, NOT just for using it to compensate the timing because of using
ron95. and one fine day if u decided to use back ron97 (IF later gov down the prices.. * in all's dream * ), u gonna go set the timing again ? why the hassle ?
if one can spent few hundreds/thousands bucks in upgrades of his/her car, and yet want to save
the tiny-winny $ to use ron95, then i dono what to say already... hahaha
maybe one word 'Bengong"
Yong_5290..I see you are a very senior zth member with around 2,582 posts and I should call you taikor already. So in that sense I believe you are a very knowledgeable car enthusiast and becos of that I believe wfhan is a little rile by your question here..actually i juz asking for fun as i would like to know from those running ron95
i presonally will run on ron97 if i get altezza coz of the engine's natural high compression
