guys RON97 price up again tomorrow, btw wanna ask you guys using RON95 or 97? Iswara year 1993 1.5 can use or not? i heard will make the carb dirty and will cause noticeable power loss. true?

i usually pump RON97, but recent hike may cause me to change to RON95.
i usually travel karak highway (up and down) will it affect my performance?

i thought carb need some carb tuning before can pump fuel with lower octane number....
Mine's tuned for 97 from factory, i scare if i pump 95 will cause engine knock, so till now still pump 97....

means RPM will be lower then usual and cause the engine to vibrate?

can cause breakdown or not?

12.5km per liter is REALLY GOOD biggrin.gif

Just wondering why you need to use RON97. There is not much difference as our ignition timing still can set to advance on RON95 provided you are using stock cam + neutral settings.

Average FC for carbie 4G1s engine are 10-11km / liter...

*
my parents got another 1.5 iswara too, they use ron95 and the FC is like 8-9km/L

retard ignition timing=loss power, and i wanna take care the car also (plan to use for at least 3 more years)

using the 3 puck exedy clutch above, the clutch pedal isn't as stiff as ppl think it is

it is moderately stiffer only, definitely can live with it

no putus cable, no other problems

as for 4g13 vs. 4g15, i fuel consumption between the 2 for me was negligible, however power difference between the 2 is very obvious

for rm1k-ish only, u get approx. 20hp instantly, where else to find such bang-for-your-buck

depends leh, carby 4g15p has quite high fc for my case, power confirm got la, but will drink more petrol also
i got not 1 but 2 saga at home, both also drink fuel 1
