Really dont know how you guys are getting so much per tank...
The most ive ever had was 350 (round trip Silverstone) last year.
That was 98% motorway and 70mph.
Since that day i have never had anywhere near that.
Normal week which is ALL motorway (live 500yrs from the m/way and work 500yrs off the other end of the m/way) Petrol light comes on at around 260 miles, winter was more round 220/230 miles. Trip mpg has never shown more than 32mpg, most the time its in the 20's (21 to 26)
My 182 was far better on fuel and i drove the 182 twice as hard as i drive the 200.
Exactly the same for me Paul!! Was lucky with 300 a tank and felt like the queen when I got 350 on a long motorway run!! 182 was much better.
