Just a general question to all out there, how many miles per gallon are you getting from your Europa?
Please reply stating type of engine (Lotus 1558 TC or what type of Renault engine), whether it is a US gallon or a UK gallon, and for those driving where it is measured in kilometres, KPG or KPL depending how you measure it.
I have just done a simple country journey with little traffic in a mildly tuned 1558 TC and cruising at 60 mph in 5th, and only got 21 mpg UK. I think there is something wrong, I was expecting 32-35 mpg UK.
