Seems to me that yes indeed, something is "way off".
I haven't seen any published figures for the fuel remaining in the tank when the you hit reserve but as you can see from the replies there is probably somewhere around 1 US gallon or just under 4 litres left when the main supply fails.
If you pull the tap off the tank, a relatively simple procedure, you'll see two pipes projecting vertically , both with fine mesh filters.
The taller of the two is your 'main supply', once the fuel drops below this level you're on reserve. I'm starting to think you may have some gunk in your tank that is blocking those fine mesh filters and causing the main supply to stop early.
Definitely worth pulling the tank off and having a look.
FWIW my '08 will go about 380 klm (236 miles) before reserve.
I have a policy of always filling the tank and always resetting the trip meter so I know exactly how my consumption is going.
I generally get about 21.5 klm/litre (50mpg) around town, and better, up to 24 klm/litre (56.5 mpg), on the highway.
