The person behind it
"I built FuelSmarter out of frustration — and a lot of time on the M4."
I found myself making regular trips up and down the M4, increasingly curious about how much my speed was actually costing me. I'd watch the fuel gauge drop faster when I pushed on — but had no way of quantifying it. Was driving at 80mph instead of 70mph costing me an extra £2? £5? More?
So I looked for a tool that could tell me. I couldn't find one. Every fuel calculator I tried just asked for distance and MPG and spat out a single number. None of them accounted for speed, road type, or the difference between a motorway cruise and stop-start city driving.
So I built one.
The same frustration came up on longer trips. You're on the motorway, you need a break, and you're squinting at those blue service station signs trying to work out if there's a Costa or a Greggs before you've already committed to the slip road. Half the time the signs are wrong, out of date, or just don't tell you what you actually want to know. So you pull in hoping for a flat white and a sausage roll, and find yourself staring at a Starbucks and a Upper Crust. Not ideal.
What started as a personal project to answer my own question has grown into something much bigger — a one-stop journey planner for any driver who wants to spend less, stress less, and arrive having actually thought their trip through.
