Gas Saving tips


An estimated 93.5 percent of motorists in the EU are driving on under-inflated tyres and causing an additional 18 million tons of carbon dioxide to be released into the environment. These 18 million tons are the equivalent of 56 million tyres being wasted. To collect this data, Bridgestone conducted free check-ups at various shopping centers and public car parks throughout Europe. Based on 2006 data, Bridgestone also estimates 40 percent of vehicles absorb an additional 2.8 percent in fuel, due to their under-inflated tyres, wasting 8.1 billion liters of fuel every year. Bridgestone, in conjunction with the FIA Foundation (Fédération Internationale de l’Automobile) and national motoring clubs, is part of the “Think Before You Drive” campaign, established in 2005.

For the first time in more than 20 years, the U.S. Environmental Protection Agency (EPA) is changing the way it calculates fuel economy estimates — the city and highway miles-per-gallon calculations that are posted on the window stickers of new cars and trucks.

A vehicle is tipically the largest or second-largest purchase made during a lifetime. So it’s important to make informed decisions about car care, including what you buy at the pump. All gasoline brands contain the minimum level of detergents required by government standard, but that level is not enough to prevent the build-up of power-robbing carbon deposits in some engines.

The summer is close, so is your vacation. Are you ready for it? Is your car ready for the amount of driving? And most off all, do you have enough money to by gas?

Engine warm-up


1. Avoid prolonged warming up of engine, even on cold mornings - 30 to 45 seconds is plenty of time.

2. Be sure the automatic choke is disengaged after engine warm up... chokes often get stuck, resulting in bad gas/air mixture.

3. Don’t start and stop engine needlessly. Idling your engine for one minute consumes the gas amount equivalent to when you start the engine.

4. Avoid "reving" the engine, especially just before you switch the engine off; this wastes fuel needlessly and washes oil down from the inside cylinder walls, owing to loss of oil pressure.

5. Eliminate jack-rabbit starts. Accelerate slowly when starting from dead stop. Don’t push pedal down more than 1/4 of the total foot travel. This allows carburetor to function at peak efficiency.

How to buy gas


6. Buy gasoline during coolest time of day - early morning or late evening is best. During these times gasoline is densest. Keep in mind - gas pumps measure volumes of gasoline, not densities of fuel concentration. You are charged according to "volume of measurement".

7. Choose type and brand of gasoline carefully. Certain brands provide you with greater economy because of better quality. Use the brands which "seem" most beneficial.

8. Avoid filling gas tank to top. Overfilling results in sloshing over and out of tank. Never fill gas tank past the first "click" of fuel nozzle, if nozzle is automatic.

How to drive economically


9. Exceeding 40 mph forces your auto to overcome tremendous wind resistance.

10. Never exceed legal speed limit. Primarily they are set for your traveling safety, however better gas efficiency also occurs. Traveling at 55 mph give you up to 21% better mileage when compared to former legal speed limits of 65 mph and 70 mph.

11. Traveling at fast rates in low gears can consume up to 45% more fuel than is needed.

12. Manual shift driven cars allow you to change to highest gear as soon as possible, thereby letting you save gas if you "nurse it along". However, if you cause the engine to "bog down", premature wearing of engine parts occurs.

13. Keep windows closed when traveling at highway speeds. Open windows cause air drag, reducing your mileage by 10%.

14. Drive steadily. Slowing down or speeding up wastes fuel. Also avoid tailgating - the driver in front of you is unpredictable. Not only is it unsafe, but if affects your economy, if he slows down unexpectedly.

15.Think ahead when approaching hills. If you accelerate, do it before you reach the hill, not while you’re on it.

General advice


16. Do not rest left foot on floor board pedals while driving. The slightest pressure puts "mechanical drag" on components, wearing them down prematurely. This "dragging" also demands additional fuel usage.

17. Avoid rough roads whenever possible, because dirt or gravel rob you of up to 30% of your gas mileage.

18. Use alternate roads when safer, shorter, straighter. Compare traveling distance differences - remember that corners, curves and lane jumping requires extra gas. The shortest distance between two points is always straight.

19. Stoplights are usually timed for your motoring advantage. By traveling steadily at the legal speed limit you boost your chances of having the "green light" all the way.

20. Automatic transmissions should be allowed to cool down when your car is idling at a standstill, e.g. railroad crossings, long traffic lights, etc. Place gear into neutral position. This reduces transmission strain and allows transmission to cool.

21. Park car so that you can later begin to travel in forward gear; avoid reverse gear maneuvers to save gas.

22. Regular tune-ups ensure best economy; check owner’s manual for recommended maintenance intervals. Special attention should be given to maintaining clean air filters... diminished air flow increases gas waste.

23. Inspect suspension and chassis parts for occasional misalignment. Bent wheels, axles, bad shocks, broken springs, etc. create engine drag and are unsafe at high traveling speeds.

24. Remove snow tires during good weather seasons; traveling on deep tire tread really robs fuel!

25. Inflate all tires to maximum limit. Each tire should be periodically spun, balanced and checked for out-of-round. When shopping for new tires, get large diameter tires for rear wheels. Radial designs are the recognized fuel-savers; check manufacturer’s specifications for maximum tire pressures.

26. Remove vinyl tops - they cause air drag. Rough surfaces disturb otherwise smooth air flow around a car’s body. Bear in mind when buying new cars that a fancy sun roof helps disturb smooth air flow (and mileage).

27. Auto air conditioners can reduce fuel economy by 10% to 20%. Heater fan, power windows and seats increase engine load; the more load on your engine, the less miles per gallon.

28. Remove excess weight from trunk or inside of car - extra tires, back seats, unnecessary heavy parts. Extra weight reduces mileage, especially when driving up inclines.

29. Car pools reduce travel monotony and gas expense - all riders chip in to help you buy. Conversation helps to keep the driver alert. Pooling also reduces traffic congestion, gives the driver easier maneuverability and greater "steady speed" economy. For best results, distribute passenger weight evenly throughout car.

30. During cold weather watch for icicles frozen to car frame. Up to 100 lbs. can be quickly accumulated! Unremoved snow and ice cause tremendous wind resistance. Warm water thrown on (or hosed on) will eliminate it fast.

Extra tips


Install pressure regulator valve (sold in auto parts stores)... Use graphite motor oil... Beware of oil additives, regardless of advertising claims... Add Marvel Mystery Oil into gas fill-ups... Investigate fuel/water injection methods and products... combine short errands into one trip... Use special gas additives to prevent winter freezing of gas lines... convert your V8 engine over to a V4.


Tips to improve your gas mileage


Drive Sensibly: Aggressive driving (speeding, rapid acceleration and braking) wastes gas. It can lower your gas mileage by 33 percent at highway speeds and by 5 percent around town. Sensible driving is also safer for you and others, so you may save more than gas money.

Fuel Economy Benefit: 5-33%
Equivalent Gasoline Savings: $0.15-$0.96/gallon

Observe the Speed Limit


While each vehicle reaches its optimal fuel economy at a different speed (or range of speeds), gas mileage usually decreases rapidly at speeds above 60 mph.

As a rule of thumb, you can assume that each 5 mph you drive over 60 mph is like paying an additional $0.20 per gallon for gas.

Observing the speed limit is also safer.

Fuel Economy Benefit: 7-23%
Equivalent Gasoline Savings: $0.20-$0.67/gallon

Remove Excess Weight


Avoid keeping unnecessary items in your vehicle, especially heavy ones. An extra 100 pounds in your vehicle could reduce your MPG by up to 2%. The reduction is based on the percentage of extra weight relative to the vehicle’s weight and affects smaller vehicles more than larger ones.

Fuel Economy Benefit: 1-2%/100 lbs
Equivalent Gasoline Savings: $0.03-$0.06/gallon

Keep your car in shape


1. Keep Your Engine Properly Tuned

Fixing a car that is noticeably out of tune or has failed an emissions test can improve its gas mileage by an average of 4 percent, though results vary based on the kind of repair and how well it is done. Fixing a serious maintenance problem, such as a faulty oxygen sensor, can improve your mileage by as much as 40 percent.

Fuel Economy Benefit: 4%
Equivalent Gasoline Savings: $0.12/gallon

2. Check & Replace Air Filters Regularly

Replacing a clogged air filter can improve your car’s gas mileage by as much as 10 percent. Your car’s air filter keeps impurities from damaging the inside of your engine. Not only will replacing a dirty air filter save gas, it will protect your engine.

Fuel Economy Benefit: up to 10%
Equivalent Gasoline Savings: up to $0.29/gallon

3. Keep Tires Properly Inflated

You can improve your gas mileage by around 3.3 percent by keeping your tires inflated to the proper pressure. Under-inflated tires can lower gas mileage by 0.4 percent for every 1 psi drop in pressure of all four tires. Properly inflated tires are safer and last longer.

Fuel Economy Benefit: up to 3%
Equivalent Gasoline Savings: up to $0.09/gallon

Choose a more efficient vehicle

Selecting which vehicle to purchase is the most important fuel economy decision you’ll make. The difference between a car that gets 20 MPG and one that gets 30 MPG amounts to $550 per year (assuming 15,000 miles of driving annually and a fuel cost of $2.20). That’s $2,200 extra in fuel costs in just four years!


Memorial Day Weekend brings the start of summer driving season, a time when Americans traditionally increase the number of miles they drive with visits to the beach, long weekends and road trips. This year, with the average price of regular gasoline at $2.928 in the United States and climbing, many families are reconsidering travel plans. While it seems that fuel prices will continue to remain at a record high, there are many simple and inexpensive ways to maximize miles per gallon and (...)
