2004 Mazda 3 Fuel Economy

My wife and I purchased a 2004 Mazda 3 around a month ago. I have to say we have been very pleasantly surprised. It runs quite smooth and gets very reasonable gas mileage. Here are the specs and my mileage results.


  • Year: 2004
  • Model: Mazda 3
  • Engine: 2.0L
  • Transmission: Automatic (triptonic)
  • Mileage: 50,000 mi or 80,000km
  • Highway speed: 80 miles/h or 130 km/h

Based on that I took my highway mileage going both directions to a location and found that I hit 38 mpg (6.2 L/100km) and 41 mpg (5.74 L/100km) respectively. Our city driving so far has been around 35 mpg (6.7 L/100km).

I will be slapping winter tires on soon, so I will do a comparison then as well. I also want to drive a slower speed and do a comparison.

Some Recent Comparisons

The last weekend in August of 2009 I drove from Calgary to Edmonton and back with some city driving while I was in Edmonton. I put on 567.3 km for the stretch I checked and used 36.04 litres of fuel. This is equivalent to 352.52 miles and 9.52 US gallons. That is a fuel economy of 6.35 L/100km or 37 miles per gallon. I drove around 115 km/h to 120 km/h on Highway 2.
