2013 Infiniti JX35: Fuel Economy Update for May

June 3, 2013

2013 Infiniti JX35

Our long-term 2013 Infiniti JX35 left us early in the month of May. In that short time we added another 800 miles to the odometer. The majority of those miles were the result of a weekend trip to Mammoth Lakes.

No records were broken in May. It seems like our JX35 fell into a comfortable fuel economy groove, averaging 18.1 mpg. This was equal to EPA city estimations.

2013 Infiniti JX35: Fuel Economy Update for April

May 2, 2013

2013 Infiniti JX35

This month our long-term Infiniti JX35 took us on a trip to the desert in Borrego Springs, California where the heat soared up to 104 degrees. Even with the air conditioning on constant blast and continual hill climbs the JX was able to maintain close to its EPA rated combined 20 mpg in sport mode.

2013 Infiniti JX35: A Magical Family Vacation, Part 3 of 3

April 29, 2013

2013 Infiniti JX35

The last leg of our week-long adventure saw Santa Monica, CA as our starting point with many different daily destinations. This was the most intensive test for the Infiniti JX35 for we worked the automobile through all forms of beachfront, city, and freeway life on the road exploring the best L.A. had to offer.

The standard of family-sized vehicles used to mean a lot of space at the expense of low MPG and high fuel costs. We traveled more than 400 miles over the week and didn't have to worry about too many stops at a gas station. I filled up after the weekend at Disneyland and didn't need gasoline until the family departed LAX and returned back to the Midwest almost a week later. The average MPG matched the OEM claims exceeding 18 mpg for the trip. Do we want more? Of course.

2013 Infiniti JX35: Arizona Road Trip Fuel Economy

April 12, 2013

2013 Infiniti JX35

Last week I drove our long-term 2013 Infiniti JX35 about 1,500 miles including a road trip from the Pacific Ocean to Scottsdale, Arizona and back. The majority of the mileage was on the highway with four folks aboard, and all of it was covered with the JX drinking 87-octane fuel.

2013 Infiniti JX35: Fuel Economy Update For March

April 2, 2013

2013 Infiniti JX35

Our long-term Infiniti JX35 traveled 1,167 miles in the month of March. They must have been some pretty tough miles because over the course of five tanks of 91 octane gas, we only averaged 16.6 mpg this month, lower than our lifetime average of 18 mpg.

2013 Infiniti JX35: Fuel Economy Update for February

March 4, 2013

2013 Infiniti JX35

During the month of February our long-term 2013 Infiniti JX35 logged a mere 885 miles and we pumped in 50.842 gallons to get there. That figures to 17.4 mpg, which comes up a little short of the EPA estimate of 20 mpg.

2013 Infiniti JX35: Fuel Economy Update for January

February 4, 2013

2013 Infiniti JX35

We accumulated just over 1,100 miles on our 2013 Infiniti JX35 in January. It was a slow month considering our goal is 1,700 miles every 30 days. Fuel economy during this stretch averaged to 18.3 mpg. This was only a tick better than our lifetime average.

The only record set this month was for the fewest miles driven. It turns out that travel by airplane does little to put miles on cars. Our goal next month is to keep the JX35 away from airport parking lots and, instead, pointed at the open highway.

2013 Infinti JX35: Wyoming Adventures Part 1 -- Fuel Economy

August 16, 2012


First, the facts then the numbers. Similar to Oldham on his vacation, I used Sport Mode exclusively, but per Infiniti's recommendation, I filled the JX with 91 octane fuel every time.

My trip was 2,679 miles long and I averaged 20.8 miles per gallon -- 3.4 mpg better than Oldham, who makes no claims to be a hypermiler. Nor am I, of course, but this is a substantial difference which I can't easily explain.

I can't complain about the JX's range. My best tank was good for 401.6 miles during which the JX consumed 19.251 gallons from its 19.5-gallon tank. Six of the eight fill ups I recorded on this trip exceeded 300 miles. My best tank was 22.2 mpg and my worst was 19.3 mpg. Probably 95 percent of these miles passed on two- or four-lane roads and the trip included two trips across Utah, which has segments where the speed limit is 80 mph. I did very little city driving.

Also, all else being equal (which it never is, of course), no case can be made for saving money by using regular 87-octane fuel in the JX. Had I averaged the same fuel economy as Oldham did on his trip and used 87-octane fuel, I would have spent $67.76 more for fuel to complete this trip (using the U.S. Energy Information Administration fuel prices for August 13, 2012).

The EPA rates the JX at 18 mpg city, 23 mpg highway, 20 mpg combined so my highway number falls at about the EPA's combined rating.

2013 Infiniti JX35: Milestone

July 24, 2012

If you grab hold of this and drive north to Bend, Oregon, and then by a miracle find your way back again to Los Angeles. you are pretty well assured that the odometer will be registering some serious miles.

Thanks to Mr. Oldham's recent adventure, the 2013 Infiniti JX35 is showing some 5,166 miles. It's a fine and luxurious ride for a family. You'll be stopping at gas stations, though, as the trip computer suggests here. And then sure as heck someone will want an ice cream.

2013 Infiniti JX35: Not Much Range

July 23, 2012


I've already posted about the miles per gallon our long-term Infiniti JX35 recorded during the recent Oldham family 2,000 mile road trip. In that post I pointed out that I'm no hypermiler, used the JX's Sport mode exclusively and ran the crossover on 87 octane fuel (91 octane is recommended) for the entire trip. Ultimately I averaged 19.7 mpg with a mix of interstate, city and two-lane driving.

The Infiniti's fuel range, however, was far more disappointing than its mileage. The crossover has a 19.5 gallon fuel tank, yet it was difficult for me to drive it further than 300 miles on a tank of gas. In fact, I only managed that feat twice over 2,000 miles (324.3 miles and 307.6 miles).

I took the above photo immediately following a fill up, which followed two tankfuls of pure interstate travel. As you can see the Infiniti's computer says there is 355 miles worth of fuel on board.

On the open road that just isn't enough. Four hundred miles per tank should be the minimum for such a vehicle under such conditions.

And of course the JX's range is worse in the city, and that's going to drive moms crazy. Around town, during mommy duties like dropping the kids off here and there and visiting Target 10 times a week, the JX's fuel range per tank is far below 300 miles.

I predict that JX owners will find this to be an issue.

2013 Infiniti JX35: Enough Power For Most, But Not All

July 17, 2012

infiniti jx front.jpg

The lease on my brother's Acura MDX is about to expire. He loves his Acuras (he changes cars every three years and has had an MDX ever since I can remember), but he mentioned that he'd been intrigued by the JX35 when he first heard news of its arrival.

After taking a closer look at the Infiniti, he decided to stick with the MDX when his lease is over.

"What was it about the JX that turned you off?"I asked him.

He replied that it was all about horsepower and torque. With the MDX you get 300 hp and 270 pound-feet of torque. The JX35 comes up a bit short, with 265 hp and 248 lb-ft in its arsenal.

I reminded him that with the JX, you get a fuel economy advantage for the hp/torque deficit. The AWD MDX gets 16 mpg city/21 mpg highway and 18 mpg combined, while the AWD JX gets 18/23/20 mpg (although, as you've no doubt read, our observed mileage hasn't quite hit these numbers). I also pointed out that for most situations, the JX offers power that's perfectly adequate.

But he wasn't sold. While I wouldn't consider him a hardcore enthusiast, he was eager and willing to sacrifice a few mpg for quicker acceleration (at 8.3 seconds, the JX is a second slower from 0-60 mph than the MDX).

How about you? JX or MDX?

2013 Infiniti JX35: Road Trip Fuel Economy

July 17, 2012


Last week I drove our long-term 2012 Infiniti JX35 2,072.7 miles from Santa Monica to Sunriver, Oregon and back. To cover that distance, which included hundreds of miles of interstate mixed with quite a bit of two-lane and city driving, the crossover needed 119.2 gallons of 87 octane gasoline. That's an average of 17.4 mpg.

Now the EPA rates the JX at 18 mpg city, 23 hwy and 20 combined, which makes it as fuel efficent or better than its seven-passenger competition.

Obviously, I came nowhere near those numbers. The best I did, and I'm in no way a hypermiler, was 19.7 mpg on an all-interstate tank. And two other all-highway tankfuls averaged just 18.2 and 18.3 mpg. My worst tank during the trip was 16.0 mpg. That tank was at least half city driving.

Maybe I should have parked somewhere else.
