1.5 usually...but also depends on ur right legs...

what if i do constant acceleration in city, with maximum speed of 90km/h in highway? which one do you prefer?

i managed to get rm10/100km on a myvi...what did i do?..rev not more than 3krpm...never full throttle...just step 20-40% on ur throttle...i doing 90-100km/h...

Sepang F1 Circuit - Sitiawan...

then i refill to full...rm25...13.02 liter manage to get 245km... 245km/13.02=18.82 km/liter...hows that?..using ultra fuel saver...

I think ur test is running on highway ler bro. Most of us to/fro home/work in KL city where can manage such good FC! Anyway, i'm monitoring my FC after today 1st service....and later add a RM99 magnet to see if it can work...LOL.

sepang to kapar on highway spedding 140km/h...Kapar-Kuala Selangor-Sabak Bernam-Teluk Intan-Sitiawan on normal road...have oncoming traffic and traffic light...

Constant acceleration meant you keep increase the speed == rate of increment of speed remain constant.

I'll be lucky i can do 60km/h constantly in KL...100km/h last maybe 5 seconds before hitting another jam.


Wanna test speed my car after 1600km also no chance...

bro
that works out to 14.21km/L
what setup are u using?
is everything stock or did u add in some mods?
i have the same car but the best i get is like 12.8km/L

mainly because different driving style and trafik condition ..

When it was RM1.62/L I managed to get 16.2km/L. And that is pure city driving with moderate traffic.

can say my driving is very conservative
i have a vacuum gauge so can monitor how hard im pressing the accelerator n so on (i try not to go less than 5mmHg)
lastime managed to get 12+km/L from my 33year old renault 1.3 (and this is using a standard butterfly valve carb while the iswara uses a linear valve)
thats y i was quite peeved when my 'new' proton got about the same milage
as for driving conditions, the time i got 12.8 was when i was doing practically all highway
when got mix of town n highway i get like on the low 12s
my tuning n tappets are all tip top (i can vouch for it as i do it all myself)
thats y wondering what he did with his car

n how does fuel cost effect efficiency?....im really confused on that part

Kancil FC depends a lot on the air filter. For optimum performance and FC, tune it on ron97 and change air filter every 5000km. The kancil FC is cheap enough to run ron97

i think the mythbusters did a take on these magnet things
the result was 'no effect' and therefore 'busted' (imagine them throwing that rusty welded metal plate with the words 'busted' onto a dusty floor )

i suggest u do wut other ppl r suggesting
fill full tank....drive from seremban to melaka and back again...n if can once again
then fill full tank again n c how much petrol u used (i.e. how much u filled the second time around)
then divide the total km traveled by the amount u filled the second time
then u can get an accurate fc
and if you still get 22.53km/L, i'm sure every single person on this forum will want to come and c ur car and copy your engine's config (including me! )
coz that kinda milage cant even be achieved by the new 'green' cars
only the new diesel cars can hit that kinda milage

Added on October 1, 2007, 11:22 pmerm...from what i heard u shouldnt use a 92 on a 97 engine
diff octane means diff combustion characteristics
u might get pinging or premature combustions which will damage your crankshaft bearings and piston rings and generally wear out/ damage/screw up your engine faster than its suppose to

Added on October 1, 2007, 11:23 pmya wor....21+km/L?....geng man that driver!

Added on October 2, 2007, 1:04 amdepends on the engine design
more powerful engines can run at lower rpms n still be able to pull
but smaller engines generally have their max torque at a higher rpms
an extreme example are super bikes
iinm, their rpm can go up to 15k+rpm or more
their cc is small...so to get the required power output, they increase the rpm
its the same concept that is being used in f1
the federation limited their cc
so to get more power, they r pushing for higher rpms

[offtopic]
wish they would make groundforce, cvt n turbo legal once again
then we'd see some really phenomenal speeds
iinm, even until today no1 can beat the cornering speeds from the groundforce era

Added on October 2, 2007, 1:12 amerm...just curious...when u say engine output 90% efficiency, what exactly do you mean?
coz iinm, an IC engine is basically a heat engine...which is quite inefficient since most energy is lost through heat...then once we factor in the mechanical losses through the transmission, we are usually looking at about 20% overall efficiency or less
only full electric cars like the tesla can get 90+% efficiency as the electric motor is very efficient
but if we talk about well to wheel efficiency, its definitely not 90%...
and lets not even talk about an IC engine's well to wheel efficiency....its just so depressing
