2013 Infiniti JX35 Long-Term Road Test


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.

The luxury crossover averaged 18.6 mpg during the week. The worst tank average was 17.2 mpg and included over 100 miles of city driving. The best tank averaged 20.1 mpg and covered only open road through the California desert.

Remember, the EPA estimates the Infiniti JX35 at 18 mpg city and 23 mpg hwy.

    Hasn't it already been determined that this vehicle recommends 91 octane and gets better mpg on 91? Thought so.

    Scott Oldham, Editor in Chief, always uses the wrong gas in 91 octane cars. His online reports on gas mileage in these vehicles are worth the paper they are written on. Oh, wait...

    i doubt that premium fuel would not increase the mpg. i GUESS this is not bad considering that it is AWD but i still think it is on the low side considering the competitors. i think that the buick encore would do better in the fuel economy department. the VQ engine familly is known to be exceptionally thirsty.

    If they keep driving the vehicle in sport mode, which hangs the CVT at higher revs, of course they will get lower mileage than is expected.

    My 2011 AWD Highlander gets about 22 on the highway and 18 in town. The JX seems like a nice enough SUV, but mileage really is poor.....likely due to the design of the VQ motor.

    My personal experience with a Infiniti G35 and VQ35: 87 oct = 15mpg mixed driving with substantially less power above 6k rpms. 91 oct = 19mpg with clean power all the way to 7.5k. Doing some quick math, that's about 27% better fuel economy AND more power. And at current fuel prices here in Cali, it's about a 5% difference between 91 and 87. So by using 87, you are in fact burning more money. If you go buy the EPA rating of 23hwy and your actual of 20hwy with 87 octane, that's still 15% difference which means that you are in fact spending more money by using 87 octane instead of the recommended 91 oct. And you can't make as much power.
