    actually i agreed with RON definition. but the reality is, lower RON tend to reduce car performance. i tested out last time with my company's CRV. it's first gen of CRV and with 33.33 liters, i can clocked at least 350km mileage on RON97. then i test with RON92 and i manage to clocked at least 350km also with RON92 but it takes 35.29 liters. i usually pump RM 60 bucks. this time with tezza, i think it might be the same case as well.

    Just finished my altezza with esso ron95... Now just fill with primax.. So far the car works fine.. Didn't notice hard knocks.. Milleage wise.. Almost the same for city driving.. Performance wise, fell some lost torque on he lower rpm.. The other thing, i seem to find my car running quiter.. Lower sound on he exhaust note.. Anther tips that i got was try to reset the car ecu first, than he ecu will calibrate back with the new fuel.. Overall, ron95 is ok for me..

    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

    im currently running with primax95. previously used primax97. not a really petronas supporter but prefer petronas because the station is everywhere! :P

    btw, cannot detect any major effect on my ride. engine feel smoother and less noise. but not test for mileage yet.

    i think i will just stick to primax95.

    Hmm...seems to be more bad feedbacks on Ron95 instead. I guess i wont dare to use it actually, but might as well try out and see the outcome.

    All this while I have been using either Shell RON97 or Shell V-Power. I realise fuel consumption for V-Power tend to be slightly better than RON97. Tested with hard driving from morning till night, V-Power FC is better for Altis 1.8G 2004 Model. Since now RON97 at the price of RM2.05 and V-power is at the price of RM2.15, i guess i'll rather pump in V-Power since is only RM3.00+ extra. Well thats my point of view lar...

    Anyhow, still uncomfortable with RON95 though..scared lost of power and damage engine like u guys said. It is true that i felt the engine performs smoother and better compare to RON97. I won't really say it does increase its power but performance wise, is much better.

    Hi
    I have tried ron95 and I find in terms of power I cant feel significant difference. Maybe top RPM
    then again it could be physiological. But I did notice fuel consumption is worse with ron95.
    I decided to stick to ron97.

    the low-end felt heavy... high-end not test yet cos my tire now are 'Semi-slick' :P

    i pumped 2nd round of esso ron95. so far , like i said, just lack of pwer only. no other prob so far with ron95. mileage, a bit less for 33.33 liters with ron95. roughly about 320km only which is about 30km lesser if using ron97. anyway, try again on esso ron95. i wan to get a firm constant mileage before deciding on which ron to use.

    haha... bro... it's about control ur foot. :P hehe... anyway, i drive 80% highway and 20% city. i hardly get stuck in jam due to my working hour. but i also believe in foot control. the more u floor it, the more it consume. like this morning, i sped to office. it consumes about 3 bar for 50km travel. normally it takes about 1 or 2 bar of fuel gauge only. :) just my 2 cents.

    i reset the ecu yesterday to find out if there were any effects by changing to Primax95.

    the 1st engine start, a bit semput. after a while, it become smoother. then take it for a test drive around pasir gudang... the result, smoother ride, better respods, quite engine, but took longer 'zero-to-hundred'.
    overall, good.

    will test the mileage this evening, jb-kl. holiday!!!

    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.
