i'm new to this forum. i'm from malaysia, driving a '04 rio 1.3 (A). this thread is interesting as FC is a big issue here in malaysia. my rio's FC is somewhat on the high side (averaging 8.8l/100km - mixed driving). this figure is ok for a 2.0 car but NOT for a 1.3, right? hmm... anyone can help me improve this situation?
when I changed my shifting habits and eased up on the gas pedal I'm getting 7l/100km most of the time and even less when I'm doing mostly hwy driving. I do use mostly ethanol blended premium gasoline...however, the mileage hasn't changed when I've gone with the cheap stuff (ethanol blended isn't available anywhere in the northwest USA....at least that I've found)
Check the owners manual, they list two sets of shift points. One for regular driving (which is what I used and got 9-10l/100km) and another for "fuel economy". Using the second set, and a light foot made all the difference.
Of course, if there is a mechanical problem....well, the lightest foot won't help you at all then
Have u change ur gaz filter?... it will give a big difference on the millage and also keep it clean once in a while by adding additif in ur gaz to clean ur injection. If u put bad gaz often ur engine will became dirty and ur car burn more gaz to do the same distance.
All highway driving. Being as soft on the gas pedal as possible. Keeping the air-conditioning off (except when going on hills and wanting to slow down). Keeping the speed at 90-100km/h whenever possible and not speeding anywhere. Avoiding the use of the brake wherever possible.
In general driving it as fuel efficiently as possible.
First: It was the most boring 450km I've ever driven. It was also hot and uncomfortable.
Second: I used 5.8l/100km (or about 17.2km per liter) so the fuel consumption was awesome.
However, when driving softly in town I usually get about 7l/100km on average mixed driving.
When I first got it and was shifting at 3,000 - 4,000rpm I was using 9-10L/100km
Driving with higher RPM, a/c on, and faster acceleration is way more fun. But driving like an old granny certainly can save you some fuel
hi guys, i've changed a few parts in my hope for a better fuel consumption. firstly i swapped the air filter with a drop-in K&N panel, super4 plugs, mobil1 (5W-50) and better tyres (falken ze512). the result is still the same, returning about 8.5 - 8.8l/100km. this is a little disappointing, guys... as for the earlier suggestion by one of our fellow forummer to change the fuel filter, i did that but did not get any significant result... hmm... any help that i can get from my fellow rio brothers & sisters out there?
Yeah, I don't have a rio but the general problem of FC is the same for all cars and it comes down to two major things. Octane and driving habitts.
If you realy wanna save fuel then don't push the peddal further than half way. Shift to upper at max 3000rpms, preferably even lower, and try to as much as possible to maintain the same speed all of the time (optimal speed for most moddern cars is around 90 km/h) above it the air resistance becomes realy high and below it the engine uses less fuel but it uses it for a longer time.
Older cars have optimum at around 70 km/h . And octane is very important cuz, higher octane fuel can give you the same power on a lower rpm rate so you can still drive your car at 90 with 1500 - 2500 rpms in 4th. in example 92 OCT fuel gives you the same power at 3500 rpms as 98 OCT fuel does at 3000rpms. so th FC goes down some ((3500-3000)/3500)*100= 15 % and the price is usualy 5 % higher
so you can save 10% of your money just by buying better (more expensive) fuel and besides that you've got the extra strength to push your car up the hill without slowing down wich can save some additional 1-2 %.
I have messured that i can get from place A to place B (some 120 km) in my pride 1.4 using from 6 l to 15 l dependant on the driving style and the fuel i used and the difference in time was 6 minutes.
thanks for the explanation & surprising comparison you did. problem is that no matter how i drive, half-pedal or not, my car still returns about the same FC to me. I did a highland tour (1800m, low atmospheric pressure, uphill climbing, etc...), i still get about 8.8l/100km. on another occasion, i drove for 3 hours non-stop on the expressway at aconstant 110km/h, the result showed that my car consumed about 8.2l/100km for the 300km trip. hmm... situation doesn't look too good here for me... for your information, the factory claim for this model is 28mpg (urban) & 35mpg(highway)...
My milage varies from 6.5l/100k - 8.0l/100k if it starts going higher, I change the air filter, oil filter and spark plugs.
It's happened twice since I bought the car that (other than driving hard) the milage has jumped, and I found the plugs are the best fix.
