How do I fix my fuel consumption problem

There are many things that can affect fuel consumption from incorrect tyre pressures or bad wheel alignment to problems with the engine.

Checking for and rectifying problems to achieve the best fuel consumption can be a rather protracted process and should always begin with an accurate fuel consumption figure. Poor fuel consumption is a common complaint but is often associated with people becoming used to a car they haven't owned for very long - driving it harder and loading it with "junk".

Winter too can adversely affect fuel consumption, especially when used for short commutes.
Another factor could be the way fuel is bought - often by a fixed amount of cash. When there is a price rise then less fuel is obtained for the money but is often perceived as an increased consumption.

Have a dealer check you computer. That controls the fuel regulation

IN order to improve fuel consumption you must make the engine run more efficiently. here are the most important ways.
typical maintenance. (check the manual)

1. check air in tires
2. oil and oil filter change
3. spark plugs change (TUNE UP)
4. air filter change


you personally can do most of these things. go to local walmart and get most of these items. very easy.

good luck.

might try changing fuel filter first...this may fix it.....

the factory mileage for fuel should be 7.2 litres per 100km but the fuel consumption will change as the car gets older so its only normal but you could improve on your fuel consumption by tuning the car

hope this helps XD

I'd be looking at a partially clogged fuel filter first choice. Also check for a possible small fuel line leak. Question for you- when was last "healthy" tune up? A plugged air filter, worn spark plugs and colder weather all contribute to a "high fuel consumption"

Last month, my wife complained of high gas usage as well. I suddenly remembered that I had forgotten to change the air filter the last time I did the oil change. It had been over 5 months since I'd put a new one in. So, we got a new air filter, and monitored the usage, and it was back to normal again. Maybe try this?

an air leak would weaken the mix of fuel to air so giving you better fuel efficiency but a poor power output.
was my last answer not to your liking, re **** fuel consumption on all fiat/alpha cars.but it is true, ask any owner........14.7 average mpg.......£205 road tax.....(tax it for a year and quadruple its value...)

it has gotta be the o2 sensor, map sensor, or the mass air flow meter.............. these are the main inputs to the computer that controls the fuel control....let me know how that works out please

the lancer get's about 23-26 miles per gallon it is a low maintenance vehicle and as long as you change the oil and do regular maintenance on it the vehicl will last a long time... please rate this
