How to Improve Gas Mileage in a Chevy Colorado in 4 Steps
Follow these truck maintenance tips to maximize fuel economy.
Step 1: Keep Front Air Dam Intact on Street Trims
Avoid removing the factory lower front bumper spoiler, which diverts wind around tires and adds 1 MPG on highways.
Step 2: Maintain 35 PSI Tire Pressure
Keep all four tires inflated to factory door placard specs to reduce rolling resistance.
Step 3: Install a Low-Profile Bed Tonneau Cover
A hard or soft tonneau bed cover smooths tailgate aerodynamic turbulence at highway speeds.
Step 4: Use Recommended 5W-30 Full Synthetic Oil
Use dexos1 Gen 3 certified full synthetic oil to protect the high-output twin-scroll turbocharger.
