Hypermiling

Core hypermiling techniques: (1) Smooth acceleration — accelerate gently and reach target speed gradually rather than pressing hard. (2) Anticipatory braking — read the road ahead and coast to decelerate rather than braking sharply, retaining kinetic energy. (3) Pulse and glide — in hybrids, this means accelerating to slightly above target speed under power, then coasting on electricity until speed drops, then repeating. (4) Optimal speed — most cars achieve best fuel economy at 45–55 mph; fuel consumption rises sharply above 60 mph as aerodynamic drag increases with the square of velocity. (5) Tyre pressure — running at or slightly above recommended pressure reduces rolling resistance. (6) Engine warm-up — avoid idling to warm up; drive gently until the temperature gauge rises. (7) A/C discipline — air conditioning can reduce MPG by 5–15% in city driving; use ventilation instead when possible.

For WorthThePump users, hypermiling has a direct impact on the detour calculation: the better your real-world MPG, the lower your detour cost, and the further you can profitably travel to a cheaper station. A hypermiler achieving 65 MPG in a car officially rated at 55 MPG will find that more stations show as 'Worth It' than the default calculation suggests.

Entering your actual observed MPG (rather than accepting the auto-derived estimate) gives the most accurate results.
