Getting less than 380kms out of a full tank of gas. 60% city driving and 30% highway driving.. anyone know why i have terrible gas mileage?
Been driving my G6 for about 3 weeks on and off. A few days in the city and 10.7L/100 km in the city, and all highway is 8.5L/100km, then my DTE Says 705 km.

damn what sort of maintenance did you do to your car? my car reads 500km when i pump it with 87 but that thing is flimsy.. i only get around 350km a tank 60%city/40%highway which is terrible.. how much kms do you get out of a tank?
I have yet to drive long enough to actually see this, but filled up and went to go see my gauge, and this is what it showed. View attachment 5433

damn that is good..the highest my car recently got on the display was 600km but on a long road trip..but the tank i have now in my car only got 220kms from full to half tank which is pathetic for a 65L gas tank.. did you do anything to your car? what maintenance repairs have you done? let me know!!
i think that their is some problem with the fuel guages. It shows the fuel economy of 11Liters/ 100 km (9KMPL) .But in actual the car has consumed 60 litres and has covered 440Km (7KMPL).
yea probably, GM are known for the fuel gauge to fluctuate..im getting about the same gas mileage now (400 from full to quarter mostly hwy)..
a day ago in order to change front light. i open up front end and found that air intake is broken. I think by removing this part my Car fuel consumption decreased a little bit.
Have a look at broken parts and plz share ur views.
How does your car sound and feel like without it? Let me know.
i think the g6s just give bad gas mileage... im in toronto and im getting from full to quarter about 350kms which is lousy (65% city driving).. and i maintain my car good.. dont know if my cats or o2 sensors are fried.. what do you guys get???
As of now i am getting 400km (toronto/canada) from full (till the gas pump clicks) to quarter in this weather. does this sound reasonable guys? most of my driving consists of about 50% city / 50% hwy.. i think its low for a 60L tank?
