Fuel tank range

[TheBuell]

I filled up the tank when I purchased it. I came home yesterday with the fuel gauge resting on the mark where reserve kicks in.  the trip computer shows 350 miles have passed. Roads have been 60% mix between motorways and 40% on small roads. Is that normal?

I'll fill up again soon and reset the trip computer and see what happens.

Thanks.

Hello Alex,

So have you filled up again to know how many gallons you have used to cover your 350 miles, and work out your mpg? 
Kind regards,

Gareth.

Yep filled up this morning. 35 litres (7.5 gallons), and as the gauge was just at the reserve mark, that's 10 litres in reserve so the average is 46 mpg. Or 10 miles / litre. Why does the specs say 577 miles per tank though.

Hello Alex,

Manufacturers claimed figures are notoriously optimistic. 
Kind regards,
