).On petrol alone, I was averaging 23.6mpg. Very little motorway driving, so mostly stop-start urban and country roads (and boy-racer accelerating!).
My first LPG run on financial comparison has got me up to 36.5mpg, so as I say, nowhere near to Mark's fuel economy, but still a marked improvement. I'll have to try as best I can to start driving more sedately and see if I can get any better.
