How many miles per gallon does a 1998 Chevy Silverado extended cab get?
Most 1998 Chevy Silverado Extended Cab pickups achieve roughly 15–20 miles per gallon in combined driving, depending on the engine and drivetrain. In practice, you can expect around the mid-teens in city use and low-to-mid 20s on the highway for the better-performing 4.3L V6 or smaller configurations, with lower figures for V8s and four-wheel drive.
Mileage by engine and drivetrain
The following figures reflect typical EPA-era estimates for common 1998 Silverado Extended Cab configurations. Real-world mileage varies with load, tires, maintenance, and driving habits.
Overview of engine options
- 4.3L V6, 2WD, automatic: roughly 16–18 mpg city and 21–23 mpg highway; combined about 19–21 mpg.
- 5.0L V8, 2WD, automatic: around 15–16 mpg city and 19–21 mpg highway; combined ~17–19 mpg.
- 5.7L V8 (Vortec 5700), 2WD, automatic: roughly 14–15 mpg city and 18–20 mpg highway; combined ~16–18 mpg.
- 4WD variants (any engine): typically 1–2 mpg lower on highway and more in city; combined often in the 15–17 mpg range.
In short, mileage on a 1998 Silverado Extended Cab is highly configuration-dependent. The 4WD models and V8s consume more fuel, while the 4.3L V6 tends to be more economical. Real-world mileage will also be affected by vehicle condition and driving style.
Tips for improving fuel economy
These tips cover maintenance, driving technique, and minor load adjustments that can help improve efficiency on older pickups.
Practical steps to maximize MPG
- Keep tires properly inflated to the recommended pressures; underinflated tires increase rolling resistance.
- Lighten the load and remove roof racks or heavy accessories when not needed.
- Adopt a steady driving style: smooth accelerations, slower speeds, and minimal idling.
- Regular maintenance: replace the air filter, spark plugs, and use the recommended engine oil and grade; adhere to tune-up schedules.
- Avoid unnecessary high-speed driving and rapid maneuvering that raise fuel use.
- Plan routes to reduce stops and start-stop driving; cruise at moderate speeds when possible.
While you can improve efficiency with these steps, a 1998 Silverado’s mpg will still be largely dictated by its age, drivetrain, and overall condition. Routine maintenance often yields the biggest gains.
Summary
Bottom line: A 1998 Chevy Silverado Extended Cab typically achieves approximately 15–20 mpg combined, with higher numbers for the 4.3L V6 and 2WD configurations and lower figures for V8s and 4WD models. Real-world results vary based on engine choice, drivetrain, maintenance, and driving habits, but thoughtful upkeep and driving practices can noticeably improve fuel economy on an aging pickup.
