Bought the car in December of 2007. This is a 2007 Nissan Versa and have been getting only about 22 to 24 miles per gallon in town. Sticker says the car gets 30 miles per gallon in town. I have never gotten close to that. Took car to dealer and they said the air intake temp was 165 degrees and they replaced the sensor. Gas mileage is still not what it should be.
