I have found that 'around town' fuel consumption is about 260 miles per tankful.
BUT, on long high-speed trips on the continent, using the 95-E10 fuel, I am getting upwards of 350 miles per tankful (thank the Lord).
Oil usage - less than quarter of a litre per 5000 miles. (I use Castrol Magnatec, Edge, or other Castrol 5W/30).
