First two fill-ups have given me 55mpg and 58 mpg (UK) - both are short on the 61.8mpg combined that the factory suggests. I've been carrying a fair bit of weight around but as it's mostly long motorway journeys I'm surprised it isn't higher.
I wonder if I ought to reconnect my cold-air feed to see if the engine is starved of oxygen. I have a feeling I'm having to work the engine quite hard to get it to climb hills etc and the cold air feed might help with that.
