How to Improve An Audi A3#039;s Gas Mileage

1. Stick to the speed limit. If you go above 60mph, the A3 will use more fuel.
2. Use your cruise control on the highway. All Audi A3 models are fitted with the cruise control feature. It helps you maintain a consistent speed, which saves on fuel consumption caused by constant acceleration and deceleration.
3. Use the Audi A3's special tools. Newer models like the A3 TDI feature a special Driver Information System to help you monitor your gas mileage. The vehicle also features two average fuel economy displays, along with a real-time MPG gauge, to inform you of the car's fuel consumption. Drive with the real-time gauge active to help you develop more efficient driving habits.
4. Turn your air conditioner off when you don't need it. Air conditioners add extra strain on the engine, causing higher fuel consumption.
5. Avoid hauling unnecessary heavy items in your A3. Unnecessary loads create more drag on the vehicle, which hurts gas mileage.
6. Keep your tires inflated at the proper pressures to increase gas mileage. See 'Resources' for a link to recommended tire pressures for all Audi A3 models.
7. Use the recommended type of motor oil for your model. Most Audi A3s use oil with a 5W-40 or 5W-30 viscosity rating, but check your manual to make sure. Using the wrong grade of oil can decrease your fuel consumption by up to two percent.
