6 banger mileage?

I'm sorry but I gotta call bs on the 28 highway. You sure the pump didn't just click off too early on accident or something? 28 highway would put you in the top 1% of slant sixers in the world.
300 some odd miles I think between Burke County NC and Morgantown WV. 80 mph, 75ish degrees. Freshman year of highschool, spring break. My first long haul drive comin in at about 6 hours. I thought it sounded wrong myself but I checked my math again and again. The only thing I could figure is my idea to put 40 psi in the tires for that trip, paid off...

btw, no pump accidents. I squeezed every bit in when I fill up, I even lift the hose up to get whats in there and than I shake the nozzel in the filler tube to get those last few drops in...
