Driving sensibly to/from work I can easily get 45 - 50 mpg out of mine (mixture of A roads and B roads using cruise control)
Get a little bored and it drops a little though...
AGP + TMC Box + Exhaust + Panel Filter.
Dont rely on the in car MPG computer... Highly innaccurate! Fiat (and many other car manufacturers) over estimate what MPG is being achieved in their cars.
Always best to calculate it yourself.
IE my grande punto says I get about 46 MPG on average. An independent MPG calculation by me reveals that the MPG is actually about 35-38
Highly inaccurate is an exaggeration. You're doing the maths wrong. The most mine has been out by is 3 MPG higher on the computer than actual. In fact, if you do 300+ miles, it's 90% accurate, basically the more miles you do, the more accurate the computer reading
