The 2020 Chevrolet Blazer FWD with the 3.6L V6 achieves 21 MPG combined. It’s a figure that won’t win any economy contests, but it’s a trade-off accepted by buyers who prioritize the Blazer’s bold styling, comfortable ride, and ample passenger space over ultimate fuel efficiency. This Blazer isn’t about hypermiling; it’s about a specific aesthetic and driving experience that some mid-size SUV shoppers find irresistible.

City and highway performance

The EPA estimates the 2020 Chevrolet Blazer FWD 3.6L at 19 MPG in the city and 26 MPG on the highway. The city figure reflects the engine’s tendency to use more fuel when accelerating from stops and idling in traffic. The 26 MPG highway rating is more palatable, and achievable on longer road trips when the 9-speed automatic transmission can settle into its higher gears. These numbers reflect how the Blazer is being used; more stop/start city driving than steady-state highway cruising affects the running costs.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 Chevrolet Blazer FWD 3.6L at exactly $2,100. This figure is based on driving 15,000 miles per year and using the national average fuel price. Individual fuel costs could be higher or lower based on local fuel prices, driving habits, and the percentage of city versus highway miles driven. It’s a useful figure for comparison, but remember that your personal expenses may vary.

Real-world expectations

While the EPA estimates provide a benchmark, real-world fuel economy often differs. Expect that aggressive driving, frequent short trips, and carrying heavy loads will decrease fuel economy below the EPA estimates. Conversely, gentle acceleration, consistent highway speeds, and proper tire inflation can help you approach or even slightly exceed the EPA highway rating. Keep in mind that climate and terrain also affect MPG.

How it compares

Within the crowded mid-size SUV segment, the 2020 Blazer’s fuel economy lands somewhere in the middle. For example, the Honda Passport manages around 22 MPG combined with its standard V6, and the Nissan Murano lands closer to 23 MPG combined. A Subaru Outback with the 2.5L engine achieves closer to 29 MPG combined, but that vehicle lacks the V6 punch and striking design of the Blazer. Even considering a smaller engine still puts the Blazer behind. Many people see the Blazer is a fashion statement and that’s why they are willing to deal with the average fuel economy.

Tips to maximize efficiency

The 3.6L V6 in the Blazer responds well to smooth, deliberate acceleration. Avoid stomping on the gas pedal unless truly necessary. A gentle application of the accelerator will keep the engine in its most efficient range, and that will maximize fuel economy.

Ensure your tires are properly inflated to the recommended pressure. Underinflated tires create more rolling resistance, forcing the engine to work harder and use more fuel. Plus, it will make the vehicle less safe on the road. Consult the tire placard on the driver’s side doorjamb for the correct pressure.

Minimize idling. If you’re stopped for more than a minute, turn off the engine. Modern engines can be restarted quickly and efficiently and the gas savings from avoiding prolonged idling can quickly add up. This is especially important in city driving.

Use cruise control on the highway to maintain a steady speed. This helps prevent sudden acceleration and deceleration, which can waste fuel. Also consider that the design of the Blazer includes more drag than a typical sedan and cruise will help deal with this.

Regular maintenance, including oil changes and air filter replacements, ensures your Blazer’s engine is running efficiently. Follow the manufacturer’s recommended service schedule to keep your Blazer in top condition. Use our site to research the BLAZER MPG across all years.
