Mostly driving on flat 50 mph roads. It equates to just short of 50 mpg, too...!
Screaming motorway journeys, though, have meant that I've got a
lot, lot less than 300 to a tank (where the light doesn't just come on, going round corners: but
stays on...), on more than one occasion: so the 370 is the exception, rather than the rule....
I do tend to drive pretty smoothly, though; and at quiet times of day/night... -- and, like you, was interested to see just how far I could push a tankful. Overall, I get around 42 mpg.
