honda city - fuel efficiency question
-
i am driving a relatively new (about 6 mths) honda city i-dsi
my car has been able to go 17+ km / litre. however there were 2 instances when the fuel efficiency fell to 15+ km / litre. (i remembered very clearly there were only 2 instances). one of them was only this sunday.
for those 2 instances, i was using the same type and grade of petrol, and i did not change my driving habits and locations drastically.
what could have led to the fall in the fuel efficiency, and why the fall to 15+ instead of a more moderate 16+?
thanks! -
I am driving the VTEC version and of cos mine FC is not as good as yours, but the last time my FC drop from 14/L to 12/L was because I was carrying alot of things in my car and also my tire pressure was damn low.....Originally posted by wuming78:i am driving a relatively new (about 6 mths) honda city i-dsi

Check it out....other things I haven check yet.... -
1. tyre pressure is lower than before.
2. driving against stronger head winds
3. something in the boot
4. maybe there's something different in the petrol -
ur tire pressure went down and maybe u are slightly more heavy footed than before.Originally posted by wuming78:i am driving a relatively new (about 6 mths) honda city i-dsi

and i'm envious you are getting more than 15km/liter.
mine is about 12 onli. -
tyre pressure... unlikely rite? if tts the case it should stay consistently low. and somemore its rather new leh.
nothing special in the boot...
but yah.. mabbe i was more heavy footed. i have to admit it grows into me - the more i drive the more i tend to accelerate and go faster!
-
ya.. 6mth is a new car.. agreed.. but u drive almost everyday (i assume).. ur tyres definitely lose air somehow this way or another..
b4 i pumped my tyres.. 1 full tank for my camry lasted me 420-430..
after i pumped my tyres.. 1 full tank lasts me for 480-500.. -
hm.. wat is the so-called norm before one needs to check on tyre pressure?
-
its best to check ur psi on ur tyres? i got a thread on tyre pressure before.. maybe u can do a search on it.
most of the tyres out there is 220. so go to the petrol station and turn the knob to 220 and pump till the bell stops ringing..
but just to be safe, check the sides of ur tyre or door sill for the suggested/intended air pressure before start pumping.
hope ur FC increases after pumping air.. cheers. -
i check every 2-3 tanks of petrol. thats about every 1.5 weeks.Originally posted by wuming78:hm.. wat is the so-called norm before one needs to check on tyre pressure?
coz i cover about 1k KM per week.
air pressure should be checked reguarly. else you may end up with uneven tire wear. which is not really a good thing besides affecting your FC. -
How you managed to do it?Originally posted by wuming78:i am driving a relatively new (about 6 mths) honda city i-dsi

Mine ride is about two months...best reading 13.5.... have been averaging 12. -
wah.. never expected this thread to be revived. u mean u r driving a new honda city idsi too?Originally posted by ewoodrovers:How you managed to do it? Mine ride is about two months...best reading 13.5.... have been averaging 12. -
ya.... i think the FC sucks...considered that 17km has been HIGHLIGHTED by the SEs..Originally posted by wuming78:wah.. never expected this thread to be revived. u mean u r driving a new honda city idsi too? -
but i have been able to achieve 16-17.Originally posted by ewoodrovers:ya.... i think the FC sucks...considered that 17km has been HIGHLIGHTED by the SEs..
of course, one's driving habits and patterns matter quite alot. -
yah..driving habits matters..or did you "open" your tiptronic very often?..
-
what's that?Originally posted by RooP:yah..driving habits matters..or did you "open" your tiptronic very often?.. -
Does "opening" of tiptronic matters at all?Originally posted by RooP:yah..driving habits matters..or did you "open" your tiptronic very often?..
By the way, i guess what is referred to as the 'opening' of the tiptronic is the to uses the button to select the gears.
Just that I can't see how it affects fc? Please enlighten. -
Could be the different between manual and auto car. Since "wuming78" doesn't know it, means he might be driving a manual car. Basically Auto car's FC is weaker than manual car, further more if you activate the "tiptronic"...... isn't it "steer-matic"?? Anyway, if you rev with an auto car, the FC will suffer much more.Originally posted by free4ever:Does "opening" of tiptronic matters at all?

Take out the spare tyre, see and feel the difference.

Accutually if u do a detailed research... i think Honda City Vtec is the fastest auto car from the 1.6 litre range and below without modification of any sort.

i seriously have no idea what a tiptronic is, but i am driving the auto version of honda city.Originally posted by wbucket:Could be the different between manual and auto car.

Tiptronic is a type of semi-automatic transmission developed by Porsche, which allows the driver to bypass the automatic mode by moving the lever into a second shift gate or gear. This is the same as downshifting to increase the braking effect of the engine or for more performance (for manual transmission vehicles).Originally posted by wuming78:i seriously have no idea what a tiptronic is, but i am driving the auto version of honda city.
By the way, your mileage impresses me. You must be really easy on your accelerator

anyway, yes, i dont rev normally. instead i choose to pick up speed gradually (or make use of slopes). normally drive 100+ on the expressway, which i spend most of my driving time on - i rarely drive in the city area. and in addition, due to my working habits and hours, i rarely need to drive when the sun is up, and that means i seldom need to hit the aircon. i guess that's how i achieve my fc. when i first got my car, it was even better - 17+ constantly, sometimes venturing close to 18! but now, its more of 16+. -
Well, I am sorry I don't know how to explain it any further. But think of it as if you are driving a manual transmissions car; when you are driving on expressway on 5th, you want to overtake a vehicle infront of you, so you'd shift one lever down (4th) for more power. This process is similar of to the Tiptronic.Originally posted by wuming78:hm.. still dont quite understand.

I didn't know Honda City also got Tiptronic, which is nice to have.
Your FC is consider very good already, considering yours an auto ride. My FC is around there also; my best was 18+ but average at around 16+ when I rev a bit plus air-con. Of course, mine is a manual ride, stock. -
Isn't Honda's control at the steering wheel? Usually you see it close beside the gear shift for auto cars, but I believe this City's is at the steering wheel. Or am I wrong?Originally posted by wuming78:hm.. still dont quite understand.
Offing air-con can result in about 1-2km/h FC improvement, interested party might want to test it out!!! -
steady bor....so hot you can tahan huh...check with other Idsi bros liao. Their FC also about the same as me ..... just have to live with it and enjoy the car lorOriginally posted by wbucket:Isn't Honda's control at the steering wheel?
