How to Improve the Gas Mileage on a Saab 9-3 Aero

Updated March 23, 2017

Improving the gas mileage on a Saab 9-3 Aero can help save you time and money at the pump. The 9-3 Aero features a powerful V6, but frequently making use of all of the horsepower can result in lower fuel economy. Despite the performance nature of the 9-3 Aero, there are some practical tips you can use to improve fuel economy in all driving conditions. Whether you have a manual transmission or one of Saab's automatics with manual mode, you can use these tips to improve fuel economy.

Start in a lower gear. By starting your 9-3 Aero in a lower gear, you can save fuel by avoiding first gear, which is the least fuel efficient. If you have a manual transmission or the shiftable automatic, simply start in second gear. This does take some practice, however, so try it in a car park before applying this tip on a busy road.

Use premium fuel. While using a high-octane premium fuel is not beneficial on all cars, it is recommended to run the 9-3 Aero on premium fuel for maximum performance and fuel economy. Although this can cost you more money at the pump, the improved fuel economy and performance is worth it for most drivers.

Keep the 9-3 Aero tuned up. Simply replacing spark plugs and adjusting the idle speed of an engine can improve fuel economy significantly. As states, fixing a major problem like a troublesome oxygen sensor can improve fuel economy by up to 40 per cent.

Inflate tires to the recommended pressure. When temperatures drop, tire pressures also drop. Not only can this lead to premature tire wear, it can also result in lower fuel economy, as too much of the underinflated tire is making contact with the road. You can find the recommended tire pressures for your car or truck in the owner's manual or in the driver's door jamb.

Avoid idling. Although keeping your 9-3 Aero running as you wait for a friend or co-worker seems trivial, it actually can decrease your fuel economy up to 19 per cent, depending on how long you idle and what accessories you use.

Accelerate slower. Although using all of the horsepower offered by your 9-3 Aero's V6 engine is exciting, it does use more fuel. Depending on your driving conditions, accelerating slower and shifting earlier can improve your economy. Even if you have an automatic transmission, lighter acceleration will result in the automatic transmission shifting earlier, which will not only save gas but also wear on your transmission.
