2008 Mazda CX-9: Sacramento Run Fuel Summary
April 08, 2008
No, the above photo does not represent a total systems failure of our 2008 Mazda CX-9. It's merely a snapshot of the 5-second bulb check that happens every time any of us starts our car. Here, near the Mazda CX-9 tach's numeral "2", you'll see a unique warning lamp that isn't common to all cars.
Check engine lights come on for a variety of reasons.
But the most common and mundane one is the missing or loose gas cap. Many a person has trudged to the dealer to figure out why the lamp is on, only to find out that their gas cap was loose or had a cut seal. The Mazda CX-9 is one of a few new cars that displays this specific and common trouble code with a dedicated lamp, avoiding unnecessary trips to the dealer.
Speaking of fuel, our 2008 two-wheel drive CX-9 is rated 16 city and 22 highway mpg. On the northern leg to Sacramento, we were in a mild hurry to make a dinner appointment, and we spent a lot of time on the freeway at just above 75 miles per hour. After 369.4 miles, we added 17.0 gallons for a 21.7 mpg average fuel economy.
On the return leg we had more time, so I set the cruise at 70 mph and left it there. After 444.0 miles long miles with a half-dozen potty and food stops, the low fuel warning finally came ablaze. It took 19.3 gallons of unleaded to fill the tank, which works out to an EPA rating-beating run of 23.0 mpg.
