30 MPG combined is exactly what the 2016 Mazda 6 2.5L 4-cyl needs to be. This isn’t a hybrid, nor is it some hyper-efficient econobox sacrificing driving pleasure to save fuel. It’s a stylish, engaging mid-size sedan, and that 30 MPG figure proves you *can* have your cake and eat it too. Buyers of the Mazda 6 typically appreciate a well-balanced car, one that offers both practicality and driving enjoyment often absent in its rivals. They’re willing to prioritize a responsive engine and sharp handling, but they still need reasonable fuel consumption for daily driving, and this Mazda delivers.

City and highway performance

Breaking down the 30 MPG combined figure, the 2016 Mazda 6 achieves 26 MPG in the city and a respectable 37 MPG on the highway. That city figure is where some competitors might gain a slight edge, especially those with hybrid variants or smaller, turbocharged engines tuned for low-end torque. But the Mazda 6’s naturally aspirated 2.5L engine offers a linear power delivery that many drivers prefer over the sometimes quirky responsiveness of smaller turbo motors. The 37 MPG highway figure is very competitive and speaks to Mazda’s engineering focus on efficiency, including aerodynamic design and lightweight construction. These features allow longer commutes and family road trips to be handled with both comfort and reasonable fuel consumption.

Annual fuel cost

Based on EPA estimates, the annual fuel cost for the 2016 Mazda 6 2.5L 4-cyl is $1,450. This figure is calculated assuming 15,000 miles of driving per year, with an equal mix of city and highway miles, using the national average fuel price at the time of testing. Your actual fuel costs will vary depending on your driving habits, the type of fuel you buy, and how many miles you drive annually. Someone who primarily drives short distances in the city will likely spend more than $1,450, while a driver who frequently takes long highway trips might spend less. However, the EPA estimate provides a useful benchmark for comparing fuel costs across different vehicles. You can find all Mazda fuel economy data on this site.

Real-world expectations

While EPA estimates provide a good baseline, real-world fuel economy can vary. Drivers who frequently accelerate hard, brake aggressively, or carry heavy loads will likely see lower numbers than the EPA estimates. Similarly, factors like weather conditions (extreme heat or cold, strong headwinds) and terrain (hilly or mountainous areas) can also impact fuel consumption. Mazda 6 owners report that the EPA estimates are relatively accurate, with many achieving numbers close to, or even slightly above, the advertised figures in mixed driving conditions, due to the car’s responsive engine and balanced transmission.

How it compares

In the mid-size sedan segment, the 2016 Mazda 6 2.5L occupies a good position in terms of fuel economy and driving dynamics. The Honda Accord, for example, achieves similar fuel economy figures, with the 2.4L non-hybrid variant offering around 27 MPG combined. The Toyota Camry, another popular choice, also delivers comparable numbers in its non-hybrid trims. The Ford Fusion offered hybrid models with significantly better fuel economy, but the Fusion’s non-hybrid engines weren’t as efficient. However, those seeking maximum fuel efficiency could opt for a hybrid variant of some of these competitors, sacrificing some driving characteristics. If you want decent MPG and don’t want a hybrid, the Mazda 6’s figure of 30 MPG makes it a good choice, particularly when you consider its superior handling and stylish design. Compare the 6 MPG across all years to see if previous or later models align better with your priorities.

Tips to maximize efficiency

The Mazda 6’s Skyactiv engine rewards smooth driving. Avoid aggressive acceleration and hard braking, as these habits consume significantly more fuel. Instead, anticipate traffic flow and maintain a steady speed whenever possible. The Mazda 6’s responsive throttle can make it tempting to accelerate quickly, but gentle inputs will yield better fuel economy.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder and reducing fuel efficiency. Check your tire pressure regularly, ideally every few weeks, and inflate them to the recommended pressure listed on the sticker inside the driver’s side door. This simple step can noticeably improve your gas mileage.

Reduce unnecessary weight. Carrying extra cargo in your trunk adds weight to the vehicle, which negatively affects fuel economy. Remove any items you don’t need on a regular basis, such as sports equipment or tools. Every pound counts, and reducing weight is an easy way to improve your MPG.

Use cruise control on the highway. Cruise control helps maintain a consistent speed, minimizing unnecessary acceleration and braking. This is especially effective on long highway drives, where variations in speed can significantly impact fuel consumption. Use this feature to maximize your highway MPG.

Consider using a lighter-weight synthetic motor oil. While not required, switching to a high-quality synthetic oil with a lower viscosity grade (check your owner’s manual for the recommended grade) can slightly reduce friction inside the engine, leading to improved fuel economy. This is a small change, but it can contribute to overall efficiency gains.
