Gas Saving Tips by Ernest Miles

The surest way you can improve your fuel cost problem is to change your motoring habits. Listed below under four categories are 30 effective methods of doing so... no need to buy expensive add-on equipment.


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.


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.


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


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.

Gas Savings Tips

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:
Equivalent Gasoline Savings:
Observe the Speed Limit
(New Information)

While each vehicle reaches its optimal fuel economy at a different speed (or range of speeds), gas mileage usually decreases rapidly at speeds above 50 mph.
You can assume that each 5 mph you drive over 50 mph is like paying an additional $0.26 per gallon for gas.
Observing the speed limit is also safer.
Fuel Economy Benefit:
Equivalent Gasoline Savings:
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 percent. 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:
Avoid Excessive Idling

Idling can use a quarter to a half gallon of fuel per hour, depending on engine size and air conditioner (AC) use. Turn off your engine when your vehicle is parked. It only takes a few seconds worth of fuel to restart your vehicle. Turning your engine on and off excessively, however, may increase starter wear.
Fuel Cost Savings:
$0.01–$0.03/min. (AC off)
$0.02–$0.04/min. (AC on)
Use Cruise Control

Using cruise control on the highway helps you maintain a constant speed and, in most cases, will save gas.
Use Overdrive Gears
When you use overdrive gearing, your car's engine speed goes down. This saves gas and reduces engine wear.

Fuel Efficent tires review by Consumer Reports Gene Petersen

Fuel-efficient tire test: Michelin Energy Saver A/S and Cooper GFE
May 18, 2010 2:20 PM
Michelin Energy Saver A/S
Photo: Consumer Reports subscribers may have noticed that we recently added two new tire models, the Michelin Energy Saver A/S and Cooper GFE, to the T- speed rated all-season tire chart. Both are marketed as fuel-efficient tires with good all-season grip.
It used to be if you wanted a fuel-efficient tire, your choices were limited to original equipment tires; automobile manufacturers often request fuel-efficient tires to bolster fuel mileage ratings. But times are changing as there is increased interest in fuel economy, and clearly tires are where the rubber meets the road.
Last year Goodyear introduced the Assurance Fuel Max, marketing it as a fuel-efficient replacement tire. On Goodyear's heels, Michelin and Cooper introduced two new competing models. Also, Continental recently introduced the ProContact EcoPlus+, which we're testing now for a future report. (See our complete tire ratings and buying advice.)
Cooper GFE

What did we find? 
Both the Michelin Energy Saver A/S and Cooper GFE performed well. The Michelin garnered an excellent overall score, second only to its sibling the long- wearing Michelin HydroEdge. The Energy Saver has exceptionally low rolling resistance and rated Good or better in nearly every test category, except for snow traction where it achieved only a Fair relative rating -- same as the HydroEdge. But where the HydroEdge excels in tread life, the Energy Saver A/S was just average achieving a Good rating.
The Cooper GFE is a very good choice overall, suitable for all-weather conditions and low-rolling resistance, but not as low as the Michelin Energy Saver A/S. Tread life is just Fair based on our test assessment, but Cooper does offer a 60,000-mile treadwear warranty, whereas the Michelin has none.
Buying tiresYou might be tempted to buy a tire solely based on fuel efficiency, but keep in mind the savings are relatively small. A 10 or 20 percent difference in rolling resistance between two tires might just mean only a one or two percent improvement in fuel economy.
No matter of what tire you buy, check the inflation pressure routinely, since underinflated tires have higher rolling resistance and will cost you miles per gallon.
When considering what tire to buy, we suggest looking at a model in our ratings with a high overall score that has good braking, handling, and hydroplaning resistance. Then, from a short list, consider a tire that suits your needs including winter grip, comfort, and tread life, and then use rolling resistance as a tiebreaker.

Great gas saving tips From Consumer Reports

A dirty air filter drops gas mileage

Our tests show that driving with a dirty air filter no longer has an impact on fuel economy, as it did with older engines. That's because modern engines use computers to precisely control the air/fuel ratio, depending on the amount of air coming in through the filter. Reducing airflow causes the engine to automatically reduce the amount of fuel being used. Fuel economy didn't change in the family sedan we tested, but it accelerated much more slowly with a dirty filter.

Warming up before driving is necessary

That was true back in the days of carburetors and chokes, but it isn’t the case with modern fuel-injected, electronically controlled drivetrains. Engines are most efficient when they’re at regular operating temperature, and the fastest way to reach that point is to drive right after starting the car.

Filling up when the air is cool gets you more gas

A common tip is to buy gasoline in the morning, when the air is cool, rather than in the heat of the day. The theory is that the cooler gasoline will be denser, so you will get more for your money. But most stations store the gasoline underground, so its temperature changes very little, if at all, during a 24-hour stretch. Any extra gas you get will be negligible.

No-name gas stations offer lower-quality fuel

Independent stations usually buy their fuel from larger, name-brand oil companies, so it’s not much different from what you’d get for a higher price down the road. Off-brand gasoline is sometimes formulated without additives designed to clean the engine, but your car should run fine on that gas.

Premium gas is always best

When it comes to regular, midgrade, and premium gasoline, oil corporations have worked overtime to drill the “good, better, best” concept into our collective driver psyche.

Premium gas has a higher octane rating, usually 91 or above, making it more resistant to pre­ignition, a condition in which fuel burns uncontrollably in the engine. Higher-performing engines are the most susceptible to preignition because they tend to run hotter, which is why premium is often recommended or required for sports and luxury vehicles.

Premium also helps maximize power in high-performance engines. With those engines, if you don't use premium, you might not get full power when, say, accelerating or climbing hills. Most drivers will probably never notice the difference.

The vast majority of cars are designed to run fine on regular. And premium won’t improve performance or fuel economy for those cars, but it will cost you about 20 cents more per gallon.

Our advice: The best gas for your car depends on the vehicle you drive. If the owner’s manual or the sticker on the fuel-filler door says that premium gas is recommended or uses similar wording, you can probably use regular. If it says premium is required, play it safe with the right octane.

Driving with windows open hurts fuel economy

Some people advise you not to run the air conditioner because it puts more of a load on the engine, which can decrease fuel economy. But others say that opening the windows at highway speeds can affect gas mileage even more by disrupting the vehicle's aerodynamics. In our tests of a Honda Accord, using air conditioning while driving at 65 mph reduced the vehicle's gas mileage by more than 3 mpg. The effect of opening the windows at 65 mph was not measurable.

Tires with low rolling resistance are always a smart choice

A lot of attention is paid to a tire’s rolling resistance, which is how much energy it takes to roll along. The lower the rolling resistance, the better your fuel economy will be. Maintaining the proper tire pressure will optimize the rolling resistance and real-world performance. Some tires gain low rolling resistance at the expense of wet-braking performance and tread life—a poor trade-off.

It’s better to look first for a tire that provides good all-around performance in important safety areas such as braking, handling, and hydroplaning resistance. Then use rolling resistance as the tiebreaker.

In our testing, we’ve found two all-season passenger-­car tires that deliver very good performance and low rolling resistance: the Continental ProContact EcoPlus+ and the Michelin Energy Saver A/S.
