How to Increase fuel efficiency

Hi friends.........
You aware and affected by high price rise in automobile fuel .
So today I am going to tell you that how to increase fuel efficiency of your Car or Bikes.
For doing so You have to follow the steps that mention below.

Don't idle : Idling a 1,200 cc engine consumes about one litre of petrol an hour. So, if you need to stop for       more than a minute, shut off the engine. However, don't opt for this if the stoppage time is lesser since it requires more fuel to restart the engine.  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.

Check the oil : Only use the recommended viscosity of engine oil as oil that is more viscous can increase fuel consumption by 2%. Also, premium fuels don't enhance the performance or mileage of the car, so stay away from these.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.

Tyre effect fuel efficiency : It is estimated that about 50% of tyres on the road are under inflated.Aside from increasing the rate of wear, this wastes fuel and decreased your fuel efficiency. Check your tyre pressures every fortnight. Worn tyres will also decrease fuel efficiency (and your safety!), so check the tread regularly. If you are replacing tyres then consider some of the newer 'Eco' tyres that are designed specifically to increase fuel efficiency.Keep your tyres properly inflated since one psi drop in pressure in all four tyres can increase fuel consumption by 0.3%.

Clean the air filter regularly : Clogged air filters reduce fuel efficiency by 3-5%, while spark plugs in a poor condition reduce the mileage by up to 3%.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.

Use only when needed : If you keep your foot pressed to the clutch pedal while driving, you'll consume 4-5% more fuel. Switch on the air conditioner only when you require it since this increases fuel consumption by about 20%. However, this holds true for city driving. On the highway, it's better to roll up the windows as this reduces aerodynamic drag on the car, lowering fuel consumption by 5%.Driving 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.Diesel Engines: If your going to buy a diesel, ensure it is a new 'common rail' type, as these are approximately 10% more efficient than older diesels. also replace (or clean if applicable) air cleaner elements as often as is required by your vehicles servicing schedule . Regular Maintenance maintains fuel 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 smoothly : Think 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.

Spark Plugs : Ensure 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.

Exhausts alter fuel efficiency : Most 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.
