How to reduce the amount of fuel consumption ?
Economical engine is yet not everything. It occurs, that the way in which we drive our car can have a considerable impact on the fuel consumption. The difference can achieve even as much as 40 per cent! A modern car of a middle class uses about 9l/100km. The same car during spendthrift driving can use up to 12l/100km or even more. But, if the driver prefers peaceful way of driving, the engine will repay with the fuel consumption
which equals 7l/100km. What can we name as a peaceful driving? It is first of all driving evenly and foreseeing, driving on the green signs, while the speed should be adjusted to other road users and the accelerator pedal should be used with deliberation.
Savings even at the beginning
Even during starting an engine you can save recently so expensive fuel. While starting a modern engine you do not have to press the accelerator pedal because the amount of fuel which is necessary for the start is regulated automatically. Not everybody knows that after the start of an engine it is better to start driving slowly than to warm up an engine in place. If we start driving just after starting an engine, the engine and catalyst are
going to reach proper temperature a lot faster.
Turning off the engine during stops
It is cost-effective to turn off the engine even during very short stops. In a modern car, turning an engine off when you stop for longer than ten seconds starts to benefit! If the car is an older one, this time prolongs to twenty seconds.
Slowing down with the engine in modern cars is very effective the fuel consumption reaches 0l/100km. Therefore it is really efficient when you are approaching a crossroads to slow down with the engine without using an accelerator pedal, you gradually change gears to the lowest one, using of course a clutch pedal as usual. The same rule is also profitable while driving a lot of older cars.
Appropriately early changing gears to higher is the next step which helps to reduce the amount of money spent for fuel. The first gear should be used only to start from a place, above 30km/h a very thrifty driver uses third gear, and so above 60 km per hour it is usual to use the fifth gear. It occurs that while driving on a higher gear and using an accelerator pedal just slightly we will spent less fuel than during driving on a lower gear with an accelerator
pedal pressed strongly.
While driving for a longer distances, the optimum speed is 110km/h. Such a speed is the best for a middle class car. Even if you are in a hurry, try not to exceed 80 per cent of a maximum speed of your car. Fast driving creates a considerable risk for the other road users, as well as the fuel consumption is disproportionately increasing .
It is better to driver with a constant speed, than to drive a part of road a lot slower and another part a lot faster. For example, if you have to drive a 130 km distance, you can drive it with a constant speed of 130 km/h and complete a distance within one hour. The other way in which you can make this distance is to drive half an hour with a speed of 100 km/h and the other half driving as much as 160 km/h in both cases it takes you one hour to complete the distance,
although in the first case the fuel consumption is considerably lower, so your savings can stay in your pocket.
Sparking plugs, filters and the other stuff
Old sparking plugs, and dirty filters can make the car fuel consumption to raise about 10 per cent. Also a heavier car is using more fuel, than a lighter one. The difference is considerable throwing about 20kg from your car, you automatically reduce fuel consumption about 0,2l/100km. The same negative effect as heavy unnecessary things have roof luggage racks. They spoil aerodynamics of a car and therefore the fuel consumption is
increasing. Open windows or sunroofs can also contribute to higher expenses at the petrol stations. Especially during fast driving when you have noticeably high speed it is advised to close all windows and vents.
Heated seats and other accessories
The current made in a vehicle is not really free Heated seats or windows are a relatively big fuel consumers. As far as the seats are concerned, the real amount of additional fuel necessary for heating them to the comfortable temperature is 0,25l/100km. We should not forget about the other fuel consumer air conditioning, which contributes to the use of even 2l/100km! Although of course if you have an air conditioning in your car it is good
to use it driving in high temperatures is almost as dangerous as drunk driving.
I'm going for newspapers
Avoiding short distances you can save a lot of money. After starting the engine it uses about 40l/100km! It is not until 4km when the usage of fuel normalizes. That's why it is better to go on foot to the newsagent's around the corner instead of driving better not only for the car, of course!
The one who do not pay any attention to the pressure in tires, not only decreases the abilities of a car or the level of safety, but also increases the fuel consumption. The pressure which is just 0,5 Bar lower from the producer's recommended can lead to five per cent higher usage of fuel or even more! If you want to save fuel and keep the safety of driving on the proper level, you definitely ought to systematically control the pressure in wheels.
