Yes....I did it I got 309.6 miles with a gallon to spare (used 7.65 gallons). To top it all off I got 40.44 mpg, my first time over 40 mpg.
So I broke two records, for me anyway, on one fill up.
Now I did most of the miles on the highway doing 70-75 with slips to 78-82 once or twice. Man this car is fun.
