1
Check to make sure you're not carrying any extra weight or unneeded items in the trunk or backseat of your car.
-
2
Use cruise control (if you have it) on the highway.
-
3
Turn off the engine instead of idling when you plan to be waiting for more than 3 or 4 minutes.
-
4
Avoid jackrabbit starts and speeding from one stop sign to the next. Accelerate slowly.
-
5
Use only high-octane gasoline (the expensive one at the pump) if your engine is pinging. Pinging is a rattling-type noise from the engine, mostly heard on acceleration and when driving uphill.
-
6
Keep all the tires properly inflated. The recommended tire pressure is listed in the vehicle's manual, stamped on the side of the tire, and often on a sticker on the driver's-side doorjamb. When in doubt, 32 pounds per square inch (psi) is a good average until other sources can be consulted. Low air pressure will cause bad gas mileage.

7
Follow a maintenance schedule. Most cars need a tune-up every year or 30,000 miles, whichever comes first. Older cars need to be serviced more frequently. A car in need of a tune-up may exhibit poor gas mileage as a symptom.
-
8
Change the air filter every 15,000 miles.
-
9
Drive just 55 mph on the highway if traffic allows you to do this safely. The faster you drive, the more gas your car will use.
-
10
Shut off the air conditioner when you don't absolutely need it.
-
11
Keep the clutch properly adjusted. A slipping clutch uses extra fuel.

Tips & Warnings
Pay attention to how much gasoline your car is using. Some problems manifest only as poor gas mileage without any noticeable drivability symptoms. See your mechanic if you notice any big changes in gas mileage.

At high speeds, the coefficient of resistance significantly affects the gas mileage. High profiled vehicles such as rigs or those with flat backs (Element. Scion, SUVs) create a lot of drag particularly at high speeds. To reduce drag during long distance driving, I slightly open the back window of the cab in my P/U truck. My gas mileage improve noticeably. Airplanes are streamlined with this concept in mind. The same physical principle applies to automobiles. -

Engine Braking Car with advance engine management systems use little to no petrol when the engine is under full vacuum (engine braking). Not only does it save you some money compared to using free gear to roll down the street, it also prolongs your brake pad's life. Window up or down People argue that with the window down, air drag will cost you more petrol money. But in reality how much they will affect you pretty much depends on your car's aerodynamics. If you drive a sports car with a sleek body, it will affect you a lot, however, if you drives around in a box-on-4-wheels from the 70's, you might as well wind down the window as it won't affect too much. Automatic vs. manual Automatic tranny cars consume more fuel due to drive train loss. However, newer Toyota and Lexus cars with automatic transmissions are rated to have better fuel economy. The same goes for a lot of JDM cars with advance transmission systems and EMS that are rated to use less fuel than their manual counterpart. Fast or slow Driving fast certainly will cost you more petrol, but driving at 25 MPH isn't doing you any good either. What is the point of driving in 3rd gear all the time? Or accelerating so slow to get to the highest gear just because jack rabbit starts cost more petrol? The best way is to accelerate normally (follow traffic, so you won't hog the road) until you reach the highest gear and stay there. Most cars consume the less fuel in 1500-2500 RPM range. Big engine vs. small engine Certainly a Chevy small block will consume a lot more petrol than a 1 liter inline 4 engine. However, if you need to carry stuff or people, and drive in hilly terrain, you are better off with a higher capacity engine. It will cost you more petrol if you need to full throttle your poor little engine. Conclusion is to choose a car with an engine that suits your driving, you will save more that way. Turn off your engine I myself gained 20% more millage from a tank of fuel just by turning off the engine at every traffic light. My car had a 1.6 liter inline 4. Lighten your car Weight cost more petrol. So lighten your car. Get rid of everything that you don't need. If you can make do without seat cushions or leather wraps, then do without them. If you want to go to the extreme you can even start stripping all the carpets or sound insulation layer. Tire and wheels I know there are people who like big big wheels with low profile tires, sure, they look nice, but they are costing you a lot of petrol money. Bigger wheels are heavier, thus giving more rolling resistance. To save fuel, find the lightest set of rims that is big enough just to clear the rotors and calipers. Legal issue If you live in a place with little to no emission control laws and you don't care about the environment, then get rid of that catalytic converter. That thing is robbing power and adds restriction to the exhaust system. Same goes to air filter. You will gain more power or better fuel economy if you can reduce the air flow restriction of your engine.
