Well I get 240 miles out of 44 litres.

Fill the tank up when the orange fuel light is pretty much on solid to full, which is 44 litres for my Rev 3 Tubby.

If I drive keeping car between 50

- 60 MPH with the odd heavy right foot action to blast round slow cars I avearge just under 6 miles a litre.

I tend to not do too much slow

/ town driving due to location of house and work, all roads near me are national speed limit except the ind estate i work on and my locak town, so even with the air con on I don't notice much of a differance in mileage per litre when driving and that's on the cheep Shell petrol, also still doing the same journeys I did not find the expencive Shell V Power stuff any better in fact the only differance I found was in my back pocket
