Increasing gas prices are causing many drivers to focus on fuel efficiency. However, purchasing a new vehicle with better gas mileage isn’t always possible. If you can’t make a large investment right now, keeping up with regular auto maintenance and changing your driving habits can make your vehicle more efficient. Here's how you can improve the car's gas mileage. 

How to Get Better Gas Mileage

1. Maintain Steady Speeds

Your engine requires extra fuel to accelerate quickly, and that fuel doesn’t get you as far if you brake suddenly. Instead, speed up gradually and maintain a consistent speed while driving so your engine has time to warm up. Leave at least a car length in front of your vehicle so you have space to stop without slamming on the brakes. 

2. Check Tire Pressure

Under-inflated tires increase resistance on the road, requiring extra rotations to travel the same distance as properly inflated tires. The recommended tire pressure level for your vehicle should be outlined on your driver's side doorwall or in the owner’s manual. Use a tire pressure gauge to check about once a month. Your dashboard may also alert you when the pressure drops. 

3. Use the Right Type of Fuel

Some drivers think that premium fuel is always better for performance and efficiency. Others with engines that require premium fuel may be tempted to save money on a lower octane. However, engines are tested to maintain optimal levels of performance and efficiency based on the octane level of specific fuels. If your engine is optimized for 89 or 91 octane fuel and you fill it with 93 octane, the engine won’t compress at the most efficient rate. Consult your owner's manual or mechanic to find the optimal fuel for your vehicle.
