- Hybrid Electric Vehicles (HEVs): Best for stop-and-go city traffic along West Morris Boulevard or US-11E, where regenerative braking boosts fuel economy.

How to Maximize Gas Mileage in a Used Vehicle
Even the most fuel-efficient car needs proper driving and maintenance habits to achieve its factory EPA ratings. Follow these 5 proven tips from our technicians at the Farris Motor Service Center:
- Maintain Tire Pressure: Underinflated tires increase rolling resistance, reducing fuel economy by up to 3%. Check tire pressure monthly.
- Replace Air & Fuel Filters: Clogged filters starve the engine of air, forcing it to burn more gasoline. Keep up with routine filter checks.
- Drive Smoothly: Rapid acceleration and hard braking drop highway gas mileage significantly. Use cruise control on flat stretches of highway.
- Remove Excess Cargo Weight: Carrying unnecessary heavy items in the trunk adds weight and drags down your miles per gallon.
- Use Recommended Engine Oil: Always use the viscosity grade of motor oil specified by the manufacturer to minimize engine friction.
