What is the gas mileage on a 2018 Chevy?
There isn’t a single gas-mileage figure for all 2018 Chevrolet models—the fuel economy depends on the specific model, engine, drivetrain, and transmission. In general, passenger cars tend to be in the high 20s to mid-30s mpg combined, crossovers in the mid-20s to low 30s, trucks in the teens to low 20s, and electric models use MPGe rather than gallons per mile. For a precise rating, check the EPA label on the exact vehicle or use fueleconomy.gov.
What drives the variation in mileage across the 2018 lineup
Fuel economy varies with engine size and type (for example, turbocharged four-cylinders versus larger V8s), whether the vehicle is front-wheel drive or all-wheel drive, the transmission choice, tires, and how heavy the vehicle is loaded. Even within a model line, trims with different engines or configurations can show noticeable mpg differences.
Representative ranges by vehicle type
Below are ballpark EPA ranges to illustrate the spread you might encounter in 2018 Chevrolet models. Exact numbers depend on trim and drivetrain; use the EPA data or fueleconomy.gov for your specific configuration.
- Sedans and light-duty cars (examples include Cruze and Malibu): roughly 28–37 mpg combined depending on engine and transmission.
- Crossovers and midsize SUVs (examples include Equinox): typically in the mid-20s to low 30s mpg combined with the 1.5–2.0L engines; larger configurations and all-wheel drive can lower the number.
- Pickup trucks (Silverado 1500 and similar): generally in the high teens to mid-20s mpg combined, with V8 models leaning toward the lower end and diesel variants delivering higher mpg in some configurations.
- Sports cars (Camaro): roughly in the low to mid-20s mpg combined for the base four-cylinder and mid-20s to low-30s for higher-performance variants, depending on drivetrain.
- Electric model (Bolt EV): uses MPGe rather than gallons per mile; roughly around the high 100s MPGe combined, depending on test cycle and year.
Note: The Bolt EV is electric and does not use gasoline. MPGe is the metric used to compare its efficiency against gasoline-powered cars.
How to find the exact figure for your 2018 Chevy
To know the precise fuel economy for a particular 2018 Chevrolet model and trim, take these steps:
- Visit fueleconomy.gov and enter the exact year, model, and trim to view the official EPA ratings for your configuration.
- Check the certified fuel-economy label on the driver’s door jamb of a new or remaining-new vehicle for the exact city/highway/combined numbers.
- When shopping used, request or review the window sticker or the vehicle history report for the specific MPG values of that car.
Real-world mileage can differ from EPA estimates due to driving style, terrain, climate, tire choice, and payload.
Tips to maximize gas mileage on a 2018 Chevy
Small adjustments can add up over time. Consider these practical steps to improve efficiency.
- Keep tires inflated to the recommended pressure; underinflation reduces efficiency and increases wear.
- Follow the maintenance schedule, use the recommended fuel grade, and keep the engine tuned.
- Practice smooth driving: gradual accelerations, steady speeds, and using cruise control on highways when appropriate.
- Lighten the load and minimize roof racks when not in use, as extra weight and aero drag reduce mpg.
- Plan trips to reduce idle time and combine errands to avoid unnecessary driving.
Bottom line: gas mileage for a 2018 Chevy varies widely by model and configuration. For the most accurate figure, reference the EPA label for the exact vehicle or check fueleconomy.gov for the specific trim and drivetrain.
Summary
The 2018 Chevrolet lineup covers a broad range of fuel economies. Sedans and small cars typically fall in the high 20s to mid-30s mpg combined, crossovers in the mid-20s to low 30s, pickups in the teens to low 20s, and electric Bolt EV uses MPGe (not gallons per mile). To get the precise mpg for a particular 2018 Chevy, consult the EPA data on fueleconomy.gov or the vehicle’s label. Real-world mileage will vary with driving conditions and configuration.
How many miles per gallon does a 2018 5.3 get?
The 5.3L engine gives the 2018 Silverado 1500 a max towing capacity of 11,100 pounds and a fuel economy of 16 mpg in the city and 22 mpg on the highway.
How many miles per gallon does a 2018 Chevy 1500 get?
The 2018 Chevy 1500 MPG varies by engine, but the EPA estimates are around 16-18 city / 22-24 highway MPG for the popular 5.3L V8. With the eAssist powertrain, estimates are about 18 city / 24 highway MPG, while the 6.2L V8 is rated at 15 city / 21 highway MPG.
EPA Estimated MPG by engine
- 5.3L V8: Approximately 16-18 MPG city and 22-24 MPG highway.
- 6.2L V8: Around 15 MPG city and 21 MPG highway.
- 5.3L V8 with eAssist: Up to 18 MPG city and 24 MPG highway.
Real-world factors
- Towing and heavy loads: Expect lower mileage when towing, as shown by one user getting around 15 MPG while towing a trailer.
- Driving conditions: Urban driving will result in lower MPG compared to highway driving.
- Modifications: Aftermarket parts, such as lift kits or larger tires, can negatively impact fuel economy.
- Vehicle maintenance: Regular maintenance, such as tune-ups and ensuring sensors are clean, can help maintain optimal MPG.
