: 540 vs 330 gas mileage observation

Boy, am I surprised. I've been cruising in a 330 Vert and averaging around 24MPG over the past 2 months. I changed cars to an E39 540 and I'm getting over 25MPG over the past 4 days driving on the same roads and the same conditions.

That's according to the computer, I'll have to double check it when I fill up again, but the 540 getting better (or at least equal) gas mileage is a big surprise.
