2014 Mazda CX-5: Fuel Economy Update For July

August 2, 2013

2014 Mazda CX-5

During the month of July, our long-term 2014 Mazda CX-5 Grand Touring AWD traveled 3,479 miles across California, Nevada, Arizona, Utah and Wyoming. In that time it used 153.9 gallons of gasoline including a mix of 91, 88 and 87 octane. Higher octane was used in hotter climates where temps were regularly above 100 degrees.

We averaged 24.4 mpg in that time, slightly lower than our overall lifetime average and below the EPA estimate for combined driving. Most of our miles this period were highway miles.

Worst Fill MPG: 20.0
Best Fill MPG: 29.9
Average Lifetime MPG: 24.6
EPA MPG Rating: 26 Combined (26 City / 30 Highway)
Best Range: 372.6
Current Odometer: 13,659

    Should that be 24 mpg city, not 26?

    3479 / 153.9 = 22.6. This is the second month in a row the stated total miles and fuel used doesn't calculate to the number stated in the update. I really like the CX-5 but I'm beginning to feel like it's real world fuel economy isn't that good. 22-24 mpg over mostly 3,000 highway miles? Please tell me they were uphill or something most of the way.

    I average 29-31 on my FWD GT whilst on fairly level highway miles. Faster speeds eat into it some, I'm assuming because of the boxy profile.

    My 2014 GT AWD with 3000 miles driven mostly around town always gets between 27.5 and 28.2 MPG. My one hiway trip 30.1. This long term CX5 has different drivers all the time perhaps that's part of the less than stellar MPG. Also a first oil change at 10,000 miles is just WRONG. I've always done my first oil and filter at 1000-1500 miles in every new car I've ever owned.

    @uthiker: I don't know about Mazda, but I know that Honda uses a kind of "break-in oil" which is supposed to allow piston rings to seat better/quicker, so it would benefit the car to maintain the first oil until its scheduled change. To be hones

    @duck87 - It always makes me laugh when I see someone ignore a manual written by the manufacturer's engineers, and the simple notion that times change and with it technology, to embrace something their father taught them on 60s-era machinery. But I know I

    Seems to me the bike wheels are out of the slip stream. The cross section of the tires along with the many spokes may be contributing to drag. Similar to the cargo net that some use in place of the tail gate on pick ups - the netting increases drag which lowers mpg. My guess is the bike rack is a Thule which secures the bikes via an adjustable arm. Wonder if the mileage will change if the bikes can be better centered into the aero dead zone behind the car.

  • You basically have a Parachute on the back of the CX5 with those bikes. Why not do a mileage test that is fair?
