My gas gauge is weird supposedly the car holds 11 gallons. I filled up on Thursday night the needle rite above E and it only took 7 gallons before it was full. If I still had 4ish gallons why was the needle even close to E? Is this the “known” issue with these cars or is their a massive reserve tank? Or is The gauge just messed up? I have also noticed I can’t get more than 24mpg but my “best” is 38.. it’s funny and doesn’t seem accurate at all.. The last car I owned a 07 cobalt had fuel gauge issues also I would start the car and it would read empty until I drove 10-15 mins or turned the car off and back on then it would read properly.. Not really looking forward to these types of issues again.
