You will not make it. It's about 30 miles, give or take, to the Chevron station. Another 10 to 15 + to the Flats. You could have Kathy drive the pickup to the Chevron station, and re fuel. Drive to the flats and re-fuel again on the way back.
Having 800 HP and 13.1 ratio is nice but you can't go any where.
