For comparison, the Plus Four fuel gauge is fairly steady and I can get to Scarborough and back on half a tank. But on the same trip in the Aero, she likes a drink and on the return journey it was down to a quarter with thirty miles still to go and thought surely I can get to the friggin east coast and back on a full tank, but bottled it just past York due to the Geiger counter nerves and had to refill.
You know it makes sense!
