Poor MPG
Depends how you drive it. This is a mainly British site, we use petrol and our gallons are different from yours as I'm guessing you are in the states.
Abstinence is fine, in moderation.

Poor MPG
In general, a normally-driven 3.0 litre should get over 400 miles to a tank (even an ///M can get over 300 miles) on a run.
However, short trips when cold will give you considerably less MPG as will doing the traffic light grand prix at every opportunity (i.e. my M can get 30 UK mpg on a run, or 17 UK MPG in stop-start traffic around town).
Automatics will also deliver slightly less MPG than manuals.

Poor MPG
I used a 3.0si Coupe as a daily for almost 2yrs. Generally speaking I got the following as my fuel economy:
- Normal motorway journeys sitting at a steady 70mph - 38-41mpg.
- Optimal conditions and being economical on the motorway - 48mpg.
- Combined - 30mpg
- Weekend trips (120miles of motorway and 80 miles or so of hooning) - 23-25mpg
- Hoons - 17mpg.
- Town only - 23mpg (plenty of unnecessary acceleration and rev matching because cool sounds).
Imperial mpg, obviously.

As others have said you should get at least 300 miles from a tank in a 3.0Si.
From tine to time both mine would show a range of 400 miles after filling up, but I never managed as many as that!

Poor MPG
Pure highway, 70 MPH with cruise control, 6SPD, ~32-34 MPG (US gallons) on 93 octane fuel . I drove the car across several states when I first got it so I had opportunity to see what the car does MPG-wise on a long, uninterrupted trip.
I get less fuel economy with 91 octane (thanks California) and city / start-stop driving.
But the fuel tank seems very small, I could almost see the fuel needle move as I was driving, very odd. Amusingly Jeremy Clarkson mentioned the small fuel tank in the Top Gear review of the S2000(Clarkson) / Z4(Hammond) / Cayman(May).

2.5si roadster 6 sp auto 33-35 mpg long term average, according to the dash display, I’ve never cross checked that with actual miles driven but it always seems pretty economical to me.

could be all sorts of reasons, read codes for obvious faults. Carry out a fuel consumption run - you should be able to see instantaneous consumtion as well as trip consumption. Check / change the aircleaner? Put some injector cleaner through it?

Poor MPG
2007 3.0si coupe. Over 1700 miles I've averaged 32.5mpg. My last tank was 36mpg.
Lots of variables to consider such as weather, tyre pressure, even tyre brand/type.

I don't drive my car everyday or do many long drives in it. I usually pop to the gym in it after a work or grab groceries. 3-4 mile round trip most evenings. My average MPG is low 20's. On a weekend I might go for a hoon, or the odd 50 mile round trip or so on the motorway to the office. etc
Not sure that's good or bad?! I feel like even on the motorway I probably get 25-30. A full tank probably says about 300miles on my dash

That's equivalent to around 38-40 mpg in UK gallons which seems pretty good!
But you're right about the tank being small. It's only 55 litres compared to the 63 litre tank in my 3 Series. It's even more annoying since I bought my MC, because it likes a drink!

Poor MPG
I have a 2005 2.5i and I'm getting about 21 mpg in the city and maybe 27/28 on the highway. I've felt that's pretty low, but my mechanic says it's about right. Mine's a 5-speed auto and I drive it moderately conservatively. I'm in the US and using 91 octane.
