My car Toyota Avensis 2010 is making 9.3 km/l or 10.9 l/100km city.
I did the following but no improvement:
1) Oxygen sensor replaced
2) MAF and throttle body cleaned
3) Spark plugs changed
4) Air filter cleaned
5) Fuel filter cleaned
6) Brake pads changed
7) Fuel injectors cleaned
Ignition coil (1) replaced
9) Catalytic converter burnt/removed

Please advise what I should do next.

Check for codes, a lot.of issues can cause that
If no codes ,change ecu or some sensors might be misleading the ecu to dump more fuel and not enough to trigger a code, make sure u are using the right sensors using the part numbers

Oga nothing is wrong with your fuel consumption, the car consumes what it designs to take. I drive Camry am doing 9-10km so no complain. Stop wasting your money and time on what is not there

As the poster before me said, there is nothing wrong with your car


City driving burns more fuel than highway driving because of the stop-and-go nvolved in city driving and the fact that the engine hardly had time to warm up and enter closed loop. Try doing highway driving and watch your mpg substantially improve...


Also try not to drive aggressively, as excessive acceleration and braking can sometimes halve your fuel economy.

Also check your vehicle for binding brakes. As in check weda any of the brakes no dey release the tyre fully after release.

Lastly, the best fuel economy trick is to not drive the vehicle... Park am, cover am with tarpaulin, and watch your fuel consumption go down to zero.

So your car gives u about 10km/Litre, 100km/10L and u are still complaining!!!!!!
Nawa oo, u for kuku say make the car no consume anything at all naa!!
Oga stop being stingy. We Nigerians too like awoof. If u want a lesser mpg u can opt for a yaris or picanto!! That one, u can use the fuel for a whole month if u like...
I wish badly that my car could give me the mpg your avensis is currently giving u.

All the best..

I serviced all the calipers to be DOUBLE sure. Thanks sir, I appreciate.

So if you buy just 3liters of Petro, you car will move 30kilometers and you're complaining. Do you know how far 30km is? Oga you car dey manage fuel big time
My car only gives me around 5km per liter fah.

even 1.0 liter engine will struggle to get that.

Omo, me I've been using 2.5 litres for 12km to and from work daily on Corolla 06, i never knew I was wasting money till this fuel subsidy issue, and someone told me he uses 1 litre for almost same journey, ive gone for computer test and it says, it's has evaporative emission system malfunction (small leakage) and they changed one pipe, still no much different, i feel like crying seeing you complaining you use only one litre for same journey.

Pls can someone advice me o,

You have to do some check yourself.

1. Check the canister purge value to see if it is still functional

2. Check for vacuum leaks in your car. Those plastic hosts from the air intake

3. Check if your fuel tank is leaking

4. . Your car should be calibrated in miles. Could be 2.5l in 12miles=12*1.6=19.2km
19.2/2.5=

Thank you, i will, kindly explain that number 4 well for me, i was lost in there...

Your car speed/mileage is calibrated in miles not kilometers

Ok, but the odometer reading, is it miles or kilometer because that's where i read from, i check reading before leaving and reading when im back. See picture below

hello bro, the matter is till on ground, please help to , this is the scan result

Bro you car is misfiring heavily. All plugs or coil should be replaced.

Your car na misfire King. E go dey do par,poe,poe,kpar,kpor from exhaust for road. Sure banker

My brother o, i tire for all these mechanics,Only the evaporative emission system code and that crankshaft code were first seen on scan the last time, then this mechanic suggest we also change all four plugs and he cleaned the injector with that can cleaner after the evaporative pipes were changed.

Then i rescanned back today, this misfire then showed, because i wasn't feeling any misfiring before atal, the movement was ok, just the massive consumption.

Now today we changed the number 1, 2 and 4 cylinder coil according to the scan... Just bought another 10litres to test again, the last 10litrs covered about 40km

No bro, ive never experienced that, check my last reply

Why did you change plugs without scanning? Those guys will drill a big hole in your pocket. I don't even go to them for little works like coil and plug replacement. I do it myself after scan

How do you all calculate fuel consumption? I’ve always wanted to calculate mine but I do not know how.

I spend around 20k to 40k weekly on fueling only

Set your odometer A or B to 0. Drive with your 20/40k fuel. Then check the total liters consumed through the odometer distance.

My brother e do me like film sef, i felt changing plug was just for routine checks, those guys always think person carry money dey waka go everywhere. Na after changing of plugs and cleaning injector that this misfiring started
