Here is the fuel economy update for our long-term 2012 Jaguar XF during the month of June. Its final day in our fleet was June 3. So we accumulated just 216 miles during the month of June. A summary of its lifetime fuel economy follows.
June 4, 2013
Our long-term 2012 Jaguar XF Supercharged, in its last month in our fleet, didn't rack up that many miles in May. A total of 1,144 miles is all we tallied last month.
May 2, 2013
Compared to its road-trip-latent history, our 2012 Jaguar XF Supercharged didn't go too far in the month of April: just shy of 1,200 miles. The Jag got plenty of use over the last four weeks and over its lifetime with us, it continues to beat EPA-combined mileage estimates.

Our long-term 2012 Jaguar XF Supercharged didn't rack up that many miles in March. A steady diet of commuting in Southern California held it to 1,353 miles. Our 470-horsepower luxury sedan broke 20,000 miles this month, though, and it might surprise you to learn that its lifetime average exactly matches its EPA combined fuel economy rating.

We put 1,602 miles on our 2012 Jaguar XF in the month of February, mostly during Carroll's road trip to Phoenix. She earned an average of 17.6 mpg in February which exactly matches our average for the lifetime of this XF Supercharged. And is slightly better than the EPA estimate of 17 mpg for this car.

If you're not careful when you put your foot down on the accelerator in our long-term Jaguar XF you can take off like a jackrabbit. Its 5.0-liter supercharged V8 is always ready even when you're not.
It packs 470 horsepower @ 6,000 rpm and 424 pound-feet of torque at 2,500 rpm. There's also a lot of midrange muscle on standby for passing and merging onto highways. It's a pleasure to drive when you get a bit of open road. I think I'm obsessed. So much so that I've chosen it from our list of cars for more than a week now. I can't get enough of its smooth power delivery and luxuriously elegant interior.

The fuel door on the right side of the Jaguar XF is one of those push-it-to-pop-it-open types. But it won't open if the car is locked. It only pops open if you have pressed the unlock button on the keyfob.
I only notice these types of security issues because I grew up in a neighborhood where people fought over parking spots as if the sidewalk was their personal property. Some of the crazies would actually put sugar in your gas tank if you parked in front of their house.

We put 1,548 miles on our 2012 Jaguar XF in the month of January. That supercharger can really takes its toll on fuel economy if you let it. But it sure makes the car fun to drive.
Our month with the XF was trouble free as it ran its usual commuting duties. The XF averaged 16.45 mpg during January and drank 94.454 gallons of 91 octane premium.
January's numbers are a little short of the 17.6 mpg we've averaged over the car's 17,791 miles and the Jaguar's 17 mpg combined EPA rating. But after all of those miles our XF is still slightly ahead of the EPA estimate as you will see below.
Donna DeRosa, Managing Editor @ 17,791 miles
Worst Fill MPG: 9.2 mpg
Best Fill MPG: 28.5
Average Lifetime MPG: 17.6
EPA MPG Rating (City/Highway Combined): 15 city/21 highway/17 combined
Best Range: 375.9 miles
Current Odometer: 17,191 miles

During the month of December we drove our supercharged 2012 Jaguar XF about 1,500 trouble-free, very enjoyable miles. During those four weeks the sedan averaged 16.7 miles per gallon of 91 octane premium.
That's right in line with the 17.5 mpg we've averaged over the car's 16,447 miles and with the Jag's 17 mpg combined EPA rating.

Our 2012 Jaguar XF runs on premium gas and has an 18.4-gallon fuel tank capacity. The EPA estimates the car should be good for 282 miles per tank.
When driving the XF, the fuel gauge seems like it moves down very quickly. But according to our fill-up records, we're getting slightly better fuel economy than the EPA ratings for the supercharged model.

The first real leg of our trip to Alaska just so happens to be one of the more boring portions of the drive. After Death Valley you just hop right back onto the 15 at Baker and drive North until Canada.
This is not an exciting drive. You go through Vegas, a chunk of Arizona, Salt Lake City and skirt Zion National Park. While there are some nice rock formations and vistas, really, this is a drive we've done before and on this trip those spots were simply dots that flew by on the nav. (I will take this opportunity to tell everyone to go to Zion National Park if you haven't done so. Spectacular.)
Two things made those dots fly by quicker...

One of the main concerns we had with taking our 2012 Jag XF Supercharged on a 7,000+ mile road trip, was the range. The EPA says that our Jag has a max range of 282 and the furthest we'd ever managed on a tank was 265.2. During that 265.2 mile tank, the driver said that he'd driven it as gently as possible had filled up when the needle read nearly zero. Still, he only managed to put 12.575 gallons of fuel in for an overall fuel economy rating of 21.1 mpg.
12.575 gallons in an 18.4 gallon tank? And it read empty? What gives?
Well, for starters, the Jag is a bit of a wuss.

Quick: What do you think of when you think of Alaska?
Bears? Russia? Seaplanes? Snow? Mountains?
All good options. If you thought "Death Valley!" then, well, sorry to break the news to you, but you may just fit in with us. Death Valley, and Badwater in particular, is the polar opposite of Alaska. Alaska is lush and verdant with abundant springs and glacial lakes. Alaska is the home of Mount McKinley (or Denali if you're into that kind of naming convention) which is the highest mountain the the U.S. Prospect Creek, Alaska is also the home of the lowest-ever temperature in the U.S at -79.8 F.
Death Valley, on the other hand, is home to the highest temperature ever recorded on the planet (take that, Libya!), 134 degrees. Badwater Basin is also, at 282 feet below sea level, the lowest point in the U.S.
This was also our last chance to have some fun with the Jag as the roads getting into/out of Death Valley are a BLAST.

Today I drove our supercharged Jaguar XF until its trip computer told me it had zero miles of fuel range. I then immediately pulled into a gas station and filled the tank. It took 16.680 gallons of premium. Jag says the XF has a 18.4 gallon fuel tank. In other words, I theoretically could have driven another 30 or so miles until the sedan would have run dry. That's a pretty big cushion Jag has built into the system.
I also want to thank Jag's engineering team for allowing the range to count all the way down to zero. Too many cars default to a useless message of "low fuel range" at somepoint, which of course defeats the purpose of the range display. If it's going to do that, a needle pointing to an E serves the same purpose.

I drove our longterm 2012 Jaguar XF over the weekend, no trips out of the ordinary, staying fairly local and driving in a normal manner -- no top speed runs or canyon strafings -- over a distance totaling 88.2 miles, to be exact.
So imagine my surprise when I fueled it up on Monday (as per Edmunds' usual practice) and calculated that the fuel economy associated with this driving was 11.1 mpg. Granted this is a one-fill result and not the consequence of an extended scientific study, but even if it was off by ten percent, it's still pretty dismal fuel economy. Especially considering I wasn't mashing the throttle at every opportunity. Just a few of them.
Our monthly fuel economy roundups have the Jag at a running average of 12.4 mpg. Plus, Jordan mentioned this, uh, trait of the XF earlier too. You've been warned...
