Love this car, first tank from dealer, got 401 miles, wasnt sure how many gal they had put in, but with a 11.1 gal tank I knew I was close to 40 mpg. Let the last bar start flashing before I filled tank, drove 5 miles while it flashed, stuffed 10.6 gal in the tank and took off, I work a midnight shift which is an advantage with traffic, as in I rarely have to stop. 100 mile round trip, lite traffic, and this tank I did not use this A.C. keep that in mind, kept it as close to speed limit as possible, very rare to go over 70 mph, this car love to go 60 mph, anyway I made one tire pressure adjustment from 29 lbs (dealer) to 35 lbs. Drove the 10.6 gals for 449 miles for 42.3 mpg. Love it!
Lighten the vehicle for even better mileage, but that is probably a safety issue
