Tires are perfect, got them check, they performed a complete tune-up, it was needed, they even plugged it into a computer, didnt find nothing wrong... but my wife gave me an idea... Why am I putting only 32 litres of gas everytime it shows me empty if the tank is supposed to hold 47 litres ? I think is the gas meter, I'm gonna get it check out... This is my first car ever, that's why I'm so ignorant about cars...lol

 

if im doing my math right you should get about 37 liters on a fully empty tank seeing that it is a 10 gallon tank. if ur only getting 250km(around 170ish miles ?) for 37 liters(about 10 gallons) liters thats rediculous. correct me if im wrong just doing some math off the top of my head from what i think i remember lol

 

Wild guess, but I think that's why he's asking how to improve it.

 

Same problem for me... I have a 2004 dodge sx 2.0. I get only 250-270 km's driving in city and highway until my light for gas comes on.
