Hello all. I recently bought a 04 Optima LX V6 and have been wondering. After about 140 miles my fuel gauge is down to 1/4. When I to refuel I only add 10 gallons. Is anyone else having the same issue? So far I am only averaging 18 mpg in mixed driving.
I have a 04 Optima LX 2.4 (4 cylinder). I have got about 5,000 miles on it. I get 24 mpg mixed driving. You should get better gas milage the more you drive it. That doesnt sound right you were at a 1/4 of a tank and 10 gallons later it was full. If it continues to happen I would take it back to the dealer.
