It works out around 500miles to the tank if your sitting around 70mph thats with a bit of stop starting but i went down to london last night and it works out 430mls to a tank sitting at a constant 80mph which i dont thnk is to bad plus my van has only the 80litre tank as opposed to the 100litre tank you can order them with. Its not a gutsy van to run about with it works out better than my 100 t280 swb l/r van that i had before. The only downside is they need a bit of wieght in the back off them cause they spin the rear wheels easy
