More tips for saving gas / petrol














1. Keep your tires properly inflated according to the manufacturer’s recommendations. Under inflated tires make the vehicle run less efficiently and waste gas.

2. Don’t be an aggressive driver. Sudden jerking starts, tire screeching stops and speeding can lower your gas mileage by 5% on city streets and as much as 33% on highways.

3. Avoid excessive idling. Idling your engine for 15 minutes wastes one gallon of gas. Whenever possible, time your traveling to avoid lingering at traffic lights and reduce the amount of time you let your car warm up. In warm weather, driving is actually the most efficient way to warm up a combustion engine.

4. Slow down. The faster you go, the less efficiently your vehicle uses gas. 55 is the most efficient mph on highways. Go above 60 and your fuel efficiency decreases rapidly.

5. Remove excess weight. If you’re used to driving around with your golf clubs and a chain saw in your trunk, you’re paying a heavy price for it. Removing an extra 100 pounds from your car will increase your fuel efficiency by as much as 2%.

6. Don’t use premium fuel unless your vehicle manufacturer requires it. Check with the manufacturing guidebook - to have the optimum type of fuel for your vehicle. High grade fuel costs much more.

7. Have a mechanic check your oxygen sensors. A faulty oxygen sensor will mistakenly send more gas to the engine then is needed. Replacing a faulty oxygen sensor can save you as many as six fill-ups a year.

8. Make sure your air filter is clean. A dirty air filter dramatically reduces fuel efficiency, so don’t just blindly follow some predetermined schedule for putting in a new one. Consider your actual driving conditions. Driving ondirt roads—or just plain dirty roads—or in heavily polluted cities will get your air filter filthy a lot faster than you might expect.

9. Check on your “forgotten filters.” Most motorists know to check the air filter when they do a tune-up, but not many think to check on the fuel filter, the PCV valve and the breather filter. Replacing these “forgotten” filters once a year or every 12,000 miles can help improve your gas mileage by up to 15 percent.

10. Get a new gas cap—and make it one with a lock. Old gas caps can get out of shape. As gas fumes expand in your tank, they can escape past a faulty seal and waste precious fuel. Some studies suggest you can save as much as 17 gallons of gas a year just by replacing an old gas cap. And consider making that new gas cap a locking model because sadly, as gas prices go up, so do gas thefts.
