Dear Sir
My wife just bought a Kia Canival 2004 model (auto). The petrol consumption level is a lot higher than expected. It is around 16 litre/100 km even if 30% of the journey was made on highway (tested over 2 weeks).
Testing method used: Fill up the tank and reset the trip meter. Then the next time, fill up to the tank again, and record the amount of petrol filled and the km on the trip metre. The readings are:
1st round: 227.5 km, consuming 36.52 litre, consumption level 16.1 litres/100 km.
2nd round: 257.7 km, consuming 40.68 litres, consumption level 15.8 litres/100 km (90 km on highway).
Kia's reported petrol consumption levels for this model are: 11 litre/100km in urban environment, and 8-9litres/100km on highway.
Would appreciate your kind assistance on what could have gone wrong.
Many thanks

PS: The tyres are nearly new, and the air pressure is normal.

You didn't mention where you are - under good conditions you should expect around 35 miles per US gallon for highway driving and around 24 in town. A US gallon is smaller than the Imperial gallon.
If you are principally highway driving, your car is probably using double the fuel it should and if it isn't leaking somewhere, the engine must be running so rich it could hardly be running smoothly and that must be causing damage - increasing engine wear and damaging the O2 sensors and the CAT and possibly fouling the spark plugs...
I expect the performance is also way down...
The most surprising thing is you aren't also complaining the check engine or other light is on - you aren't so maybe it isn't? You didn't mention any of this sort of stuff so maybe it is running ok?
I suggest you check your fuel system for leaks as a matter of urgency and then perform an accurate fuel consumption check and post again.
best at 10 liters per 100 klms , average around 12 liters /100 klms
fuel consumption depends largely on load , speed , operating conditions , towing, highway/city, off road so an exacting answer is not possible as it all depends on the operator and the driving skills
why what is the car doing few tips get it serviced and tuned make sure tyres are correct presurse dont drive like an ideot haha lots of stop starting uses a lot of fuel not a lot to go on
That 6km/L is about 17mpg in Canadian imperial gallons. You'll only achieve the 'optimal' 26 mpg (~9.1km/L) figure IF:
1) your car is well tuned/maintained, and
2) you're mostly cruising at around 80 kmph on a level highway with no headwind, and
3) you drive VERY 'conservatively' when in city traffic
As far as tuning/maintenance you'll want to ensure that your air filter isn't dirty and your plugs, emission & ignition systems (including sensors) are all functioning properly. You should also use the 'regular' grade of gas as recommended by the manufacturer. Using a higher grade ('hi-octane') or ethanol blended fuel will reduce both performance and mileage. Adding a premium aftermarket lubricant (like DuraLube, Slick 50, or a similar product) to the oil at each oil change will also help increase your mileage, reduce engine wear, and make for easier cold-weather starts.
When driving exclusively in stop-and-go city traffic you can expect to achieve a MUCH lower than that optimal 'dealer' figure.. perhaps in the vicinity of 20 mpg. Fuel consumption also depends to a large extent on how fast you accelerate. Keeping a 'light foot' on the gas pedal while avoiding too many unnecessary stops or rapid energy-robbing decelerations will also get you a lot farther for your dollar.
15000kms is a lot of mileage and i would expect it to burn some oil in this period ,i would suggest that oil is changed every 6000kms with a oil filter every third oil change ,use the cheapest oil you can buy from supermarket for a petrol/turbo diesel engine and you will never have problems with the internal workings of the engine caused by clagging up of black hard carbon
I would not really recommend buying a petrol engined Isuzu if you are thinking about fuel consumption.I think you will be lucky to get 8km/l and thats being generous.Rather go for a turbo diesel with around the same capacity and you should get between 12-14km/L.
Hi, its time for a ring set job in this vehicle. the blue smoke is a sign of major oil consumption due to bad piston rings. you also have faulty valve seals as well. this is deep engine repair and it will be costly.
If you cant do this job soon, be sure to watch the oil consumption by checking the level regularly and, monitor the oil pressure as well.
