We added just over 1,300 miles to our 2013 Porsche 911 convertible in November.
Our best and worst fill numbers haven't changed since last month but our overall fuel economy dropped slightly to 21.0 mpg. We're running slightly behind the EPA combined estimates.

We added about 1,200 miles to our 2013 Porsche 911 Carrera convertible during October. It didn't make any big road trips, so that mileage was largely racked up by our typical commuting within Southern California.
For the month, we averaged 20.9 mpg. That's close to our lifetime average since we started the test back in January.

Our 2013 Porsche 911 Carrera Cabriolet has performed relatively the same as last month. We're averaging a little below the EPA combined estimate, as we have all along.
In August we drove our Porsche 1,170 miles, using about 64 gallons of 91-octane fuel.

Our 2013 Porsche 911 Carrera Cabriolet is running just below the EPA expectations for combined city/highway driving.
I've been driving it for the past few days and I can tell you I've been cranking the A/C in our 911 because of the late summer heat wave we've been having.

Now that our Porsche 911 has settled back into daily driver duty after its cross country trip, its mileage has suffered a bit. Its overall mileage number dropped from 22.8 to 22.4 after several tanks of, uh, let's call it aggressive driving.

With the last few tanks of our cross-country road trip figured in, our 2013 Porsche 911 has now bumped its lifetime fuel economy number up another notch. Unlike last month, however, this time it was a mere tenth of a mile per gallon, from 22.7 to 22.8.

To be fair, I didn't know we were competing on fuel economy until I read Erin's post after I'd gotten home. I didn't know I was supposed to be trying for fuel economy.
I just knew this was a Porsche and that, after the first day's error, my radar detector was working very well.

So our long-term 2012 Porsche 911 Carrera Cabriolet made it from L.A. to New York. But that was only the first half of the road trip. I've turned the keys over to Mike Magrath for a second half. He's not taking the same route, of course. And he'll probably put the top down no matter how cold it is.
It goes without saying that we're competing on fuel economy. It's not just about logging the highest overall average mpg, either. It's about who gets the best mpg on a single tank, worst mpg on a single tank, and the most miles on a single tank. There's also the matter of who spends the most money on premium fuel.
Check my totals after the jump. These are the numbers Magrath has to beat.

Our Porsche 911 Carrera Cabriolet packed on 6,225 miles in the month of March. A cross-country road trip helped its fuel economy numbers significantly.

During the month of February we drove our 2013 Porsche 911 Carrera Cabriolet about 940 miles. During those almost-four weeks the sedan averaged 15.4 miles per gallon of 91 octane premium.
That's quite a bit lower than the 16.7 mpg that we've averaged over the car's 2,214 miles and the Porsche's 21.5 mpg combined EPA rating. The reason? Hard driving. The Porsche saw particularly spirited use this month and was also track-tested, where the throttle is used with impunity, eroding its fuel economy.

The 2013 Porsche 911 Carrera Cabriolet has been with us since the beginning of January, and we've burned just six tanks of 91 octane fuel so far.
