I average around 350 miles per tank, usually fill up right around 10 gallons per fill up.

If I really try to stretch it, run no AC, and keep my RPMS at the lowest point, drive around 60 on the freeway, and also try to never come to a stop I can get upwards of 375-400 miles.

When I took it down to florida (1070 miles one way) my best tank was 430 miles. This was achieved by doing all Freeway, no stopping, during the morning hours (was nice and cool around 50f) and driving around 60.
