 ```Hello, iamreallybusy-ga! Some excellent tips can be found on the FuelEconomy.gov website. See the site for Data Source information. See "Driving More Efficiently." http://www.fueleconomy.gov/feg/driveHabits.shtml 1. 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: \$0.13-\$0.88/gallon 2. 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 \$0.19 per gallon for gas." Fuel Economy Benefit: 7-23% Equivalent Gasoline Savings: \$0.19-\$0.62/gallon 3. Remove Excess Weight ======================== "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-\$0.05/gallon 4. Avoid Excessive Idling ========================== "Idling gets 0 miles per gallon. Cars with larger engines typically waste more gas at idle than do cars with smaller engines." 5. Use Cruise Control ====================== "Using cruise control on the highway helps you maintain a constant speed and, in most cases, will save gas." 6. Use Overdrive Gears ======================= "When you use overdrive gearing, your car's engine speed goes down. This saves gas and reduces engine wear." Also See "Keeping Your Car in Shape." http://www.fueleconomy.gov/feg/maintain.shtml 7. 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." Fuel Economy Benefit: 4% Equivalent Gasoline Savings: \$0.11/gallon 8. Check & Replace Air Filters Regularly ========================================= "Replacing a clogged air filter can improve your car's gas mileage by as much as 10 percent." Fuel Economy Benefit: up to 10% Equivalent Gasoline Savings: up to \$0.27/gallon 9. 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." Fuel Economy Benefit: up to 3% Equivalent Gasoline Savings: up to \$0.08/gallon 10. Use the Recommended Grade of Motor Oil ============================================= "You can improve your gas mileage by 1-2 percent by using the manufacturer's recommended grade of motor oil...." Fuel Economy Benefit: 1-2% Equivalent Gasoline Savings: \$0.03-\$0.05/gallon Additional Resources ===================== "Get Better Gas Mileage."

 ```1) Use the brakes less... Every time you touch the brakes, you are wasting momentum that you gained by wasting gas (and you're also wearing out your brakes) This sounds overly simple sometimes or impossible others, but it is a simple matter of strategic driving. Don't tailgate, let off the gas early before sharp turns, let off the gas in plenty of time before stoplights (if you think it will be red as you approach it)... use common sense while driving to avoid wasting brakes (and gas). 2) Don't accellerate quickly. A slower gradual accelleration uses less gas to go the same distance. 3) Use regular grade gas. Most cars actually perform better on the lower grade of gas than the higher grades. They are designed this way. Unless your car manual specifically says to use plus or premium gas, then use regular for best performance. 4) Sell your gas guzzler and buy a car that gets 35+ mpg. By far the biggest factor in your miles per gallon is the type of car you are driving. Everything else you do will only change your gas mileage by 10% or so. 5) Drive a manual car rather than automatic. Better mileage, cheaper maintenance, cheaper purchase price, more control, more power... all around a better deal. 6) Maintain proper tire pressure. 7) Draft behind big trucks. Many people say that this is dangerous... but keep in mind that a truck can't decellerate nearly as quickly as a car. Keep a 1.5 second distance between you and the truck and pay attention... I find this safer than a 2 second distance behind a car (car drivers are much more prone and able to slam on the brakes)```

 ```Fill your tires up with helium or hydrogen, less curb weight = better mileage. Get a car that has better mileage! Hybrid's will use less gas but cost the same when price/repair is included. It's not the question but the most viable solution. Use Acetone additive to your gasoline. There are also many other additives that may or may not increase mileage.```

 ```Uhh. helium and hydrogen are highly flammable so I don't think that's the best idea lol! Use biofuels or fuels with less harmful effects on the envronment to save the planet..not the original question as the previous commentor said but everyone has to do their bit```

 ```I have never heard of filling automotive tires with hydrogen or helium. I can't imagine it would make an appreciable difference in tire weight. The tires would also lose air faster than if they were filled with regular air. One more thing. Only hydrogen is flammable. Helium is not.```

 ```Introduce water to the fuel intake system. It must be totally misted, virtually like steam, with so ' solid' water in it. I have seen a working model but the carby had to be about twenty feet [ through 4 inch pvc pipe] from the intake manifold to give the water time to turn to mist. Economy went from 20 miles per gallon to fifty on a standard 6 cylinder [ in line] motor.```
