>higher pressure should be used to maximize fuel efficiency. Deflated tires

>prematurely, affect the vehicles adversely, and hurt the fuel economy by
>increasing the rolling resistance. Tires lose about 1 psi pressure per
>month due to air loss caused by the tire hitting holes, bumps and curbs.
>Therefore, the tires should be checked at least once a month. Just 1 tire
>deflated by 2 psi will result in a 1% increase in fuel consumption.
>
>2) Drive at moderate speed Avoiding high speeds on open roads results in
>safer driving and better fuel economy. In highway driving, over 50% of the
>power produced by the engine is used to overcome aerodynamic drag. Drag
>and thus fuel consumption increases rapidly at speeds above 90km/h. On the
>average, a car uses about 15% more fuel at 100km/h, and 25% more fuel at
>110km/h compared to when it is doing only 90km/h. However, this should not
>lead one to conclude that the lower the speed, the better the fuel economy
>- because it is not. The fuel consumption of an average car increases
>sharply at speeds below 50km/h.
>
>3) Clean the air-filter regularly Clogged air filters increase fuel
>consumption by restricting airflow to the engine, and thus should be
>cleaned/replaced when necessary. Clogged air filters can increase fuel
>consumption by up to 10%.
>
>4) Use thinner tires Tires with thick width will improve the handling of
>your car. However, it will also increase your car's fuel consumption.
>Thicker tires mean more rolling resistance! , and thus will consume more fuel.
>
>5) Start up the car properly With today's cars, it is not necessary to
>prime the engine first by pumping the accelerator pedal repeatedly.Do not
>crank the engine excessively This only wastes fuel.When starting the
>engine, idle it no more than 30 seconds to warm it up. An engine will warm
>up faster on the road. However, avoid sudden acceleration before the
>engine has warmed up sufficiently.
>
>6) Drive in high gear (overdrive) The engine runs most efficiently between
>around 1,500 and 2,500 rpm. To maintain these low revs you should change
>up through the gears as soon as practical and before the revs reach 2500
>rpm. For automatic transmission cars, you should always switch on your
>overdrive to help save fuel. Overdrive will allow your engine to change
>gears at lower revs. It also puts your transmission into an "economy" mode
>and lets it engage the final "overdrive" gear when cruising to ! keep the
>rpms extra low, thereby increasing fuel economy.
>
>7) Travel light Avoid carrying any unnecessary weight in your car. On the
>average, every 50kg added load in your car will increase fuel consumption
>by 2%.
>
>8) Anticipate traffic ahead A driver can reduce fuel consumption by up to
>10% by anticipating traffic conditions ahead and adjusting the speed
>accordingly, and avoiding tailgating and thus unnecessary braking and
>acceleration. Accelerations and decelerations waste fuel. Braking and
>abrupt stops can be minimized by not following too closely and slowing
>down gradually when approaching a red light. It takes up to six times as
>much fuel to move a car from a dead stop than it does for one moving at
>just a few km/h.
>
>9) Avoid strong acceleration The fuel consumption remains at a minimum
>during steady driving at a moderate speed of about 90km/h. Keep in mind
>that every time the accelerator is hard pressed, the engine goes into a
>"fuel-enrichment" mode of operation that wastes fuel.The vehicle should
>always be gradually and smoothly accelerated. Using cruise control on
>highways can help maintain a constant speed and reduce fuel consumption.
>
>10) Minimise aerodynamic drag Additional parts on the exterior of a
>vehicle such as roof racks and spoilers, or having the window open, Roof
>racks are bad for fuel economy increases air resistance and fuel
>consumption, in some cases by over 20%.
>
>11) Don't let your engine idle Minimize fuel wasted in idling by stopping
>the engine whenever your car is stopped or held up for an extended period
>of time. Idling more than a minute consumes much more fuel than restarting
>the engine. By having the engine switched off, you will save more fuel
>than is lost from the burst of fuel involved in restarting the engine. The
>net increased wear and tear from this practice is negligible.
>
>12) Use the air-con sparingly Air conditioners can use about 10 per cent
>extra fuel when operating. However, at speeds of over 80 km/h, use of air
>conditioning is better for fuel economy than an open window.
