Well pleased to get 864.2 miles which is 69.36 MPGus (3.4 l/100km, 83.3 MPGuk) out of my last tank. I think this is pretty good considering I drive at 65mph average, I don't do P&G, and this includes 5% city driving and 3 hours stuck in stop-go traffic.
One day once I get cruise control installed, I will try commuting at 55mph, see what MPG I get.
Unfortunately, in the UK it's very difficult to P&G on our busy motorways and I don't really fancy the effort of P&G, but it'd be awesome to find out what MPG I can get out of my old car if I did P&G.
Shame my usual commute don't get this mileage, I think it's because my car takes at least 10 minutes to warm up to normal temperature and there's *lots* of traffic lights on the first 2 miles of the commute (something like 20) designed to waste fuel.
