Tips to Reduce Fuel Consumption & Increase Efficiency

Use your gears wisely.
Driving in the highest gear possible without labouring the engine is a fuel-efficient way of driving. A vehicle travelling at 60kmph in third gear uses 25 percent more fuel than at the same speed in fifth gear
Drive smoothlyThink ahead!
By applying light throttle and avoiding heavy braking, you can reduce both fuel consumption and wear and tear. Try to predict traffic at junctions and when in queuing to avoid accelerating and then braking. Research suggests driving techniques can influence car fuel efficiency by as much as 30 percent.
Switch off your engine
There are two schools of thought on this one. Switching your engine off for short periods of time can actually increase fuel consumption, as it requires more fuel to get the engine started. Also your catalytic converter will no longer be running at full temperature and so your car will be less efficient, increasing the amount of pollution you cause. However if you are stopped for more than a few minutes then your car will simply burn less fuel with the engine stopped.
Drive off promptly to prevent wasting fuelDon't leave your engine running when you first start up. Drive off straight away if you can, but drive gently until the engine has reached its normal operating temperature. This doesn't increase fuel efficiency as such, but it does mean your engine is switched on for less time.
Lighten your loadThink
with your windows open drastically reduces your fuel efficiency, far more so than putting the air conditioning on when motorway driving. So in those hot summers(?) preferably keep the windows shut, and the air conditioning on if you want to keep cool. Of course the air conditioning decreases fuel efficiency too, so try not to over use it.
Invest in a new fuel efficient carNew cars come in all shapes and sizes, but it is possible to pick a new car that can greatly reduce your fuel bill, and your fuel emissions.
Size matters. Choose an economical car - small cars use far more fuel efficient and produce lower emissions than large cars.
Drive the most fuel-efficient car that meets your needs.
One of the most common reasons for a drop in fuel efficiency is a dirty intake filter. This will decrease the amount of air entering the cylinders of the engine resulting in incomplete combustion. Check the filter regularly to ensure that it is clean.
Spark PlugsEnsure your spark plugs are in good condition. Renew the plugs and wires at intervals specified by the owners manual. This will keep all cylinders firing properly resulting in higher efficiency.
Lube Oil:
Change the lube oil at intervals specified by the owners manual. Use the recommended oil only especially in newer cars. Use of an engine flush before changing the oil will help to get rid of a lot of the dirt that collects in the engine that a normal oil change will not remove. On older engines it is advisable to use an oil treatment agent. This basically thickens the oil which creates a better seal between the piston and the liner, preventing blow past and consequent loss of combustion pressure, resulting in higher fuel efficiency.
Exhausts alter fuel efficiencyMost cars have special sizes for the exhaust. When cars are reasonably old the silences has to be changed. The garage people always try to fit a size that they have in the garage it self. Which might not be the exact size recommended for the car. The wrong size a bigger or smaller silencer size effects on the MPG of the car and the HP of the car.
It may be cheaper to put another size than your recommended size for your car but on the long run it will cost you in many ways, especially on fuel consumption. Always put the recommended size of the exhaust that is indicated in your car manual because the car company knows how to optimize the performance of your car.
