Its very easy to improve the fuel efficiency of your car as much as 30 % by simple vehicle maintenance and driving behavior. Here are some simple tips that will not only reduce the greenhouse gases but also save some money for you.
Don’t be aggressive driver on road
Rapid acceleration and hard braking can increase fuel consumption by as much as 40%. Tests show that Rapid acceleration and hard braking reduces travel time by only four percent, while toxic emissions were more than five times higher. The proper way is to accelerate slowly and smoothly, then get into high gear as quickly as possible. In city driving, nearly 50% of the energy needed to power your car goes to acceleration.
Try to maintain constant speed while driving
Increasing your highway cruising speed from 90km/h to 120km/h can raise fuel consumption as much as 20%. You can improve your gas mileage 10 – 15% by driving at 90 kmph rather than 100 km/h.
Note how quickly efficiency drops after 100 kph.
Switch off the vehicle when on idling
In both summer and winter. Idling wastes fuel, gets you nowhere and produces unnecessary greenhouse gases. If you’re going to be stopped for more than 30 seconds, except in traffic, turn off the engine. In winter, don’t idle a cold engine for more than 30 seconds before driving away. (Older vehicles, however, may need more idling time when first started. In cold, winter conditions all vehicles may need more idling time to warm up and ensure the windshield is fully defogged. Be sure your vehicle is warmed enough to prevent stalling when you pull out.)
Do regular maintenance of your car
According to the manufacturer’s instructions. A poorly tuned engine can use up to 50% more fuel and produces up to 50% more emissions than one that is running properly.
Air filters: Dirty air filters can also cause your engine to run at less than peak efficiency Regular visual checks of the air filter will tell you if it needs replacing and your owner’s manual will also recommend appropriate replacement intervals. Clogged filters can cause up to a 10% increase in fuel consumption.
Oil: Using the correct viscosity oil is important because higher viscosity oils have greater resistance to the moving parts of the engine, and therefore use more gas. Clean oil also contributes to better gas mileage. It is usually recommended that engine oil be changed every three to five thousand miles.
