how to mechanically reduce fuel consumption in cars

how to mechanically reduce fuel consumption in cars is a question that interests many drivers. Curiously, just 10 to 15 years ago, many drivers did not even think about how to save on gasoline. But earlier on the machines were much more powerful engines than modern small cars. In some cases, fuel consumption was as much as 20 liters per 100 km and no one was surprised at this. Previously, gasoline was cheap.

Now let’s move on to the topic of how to mechanically reduce fuel consumption in cars that will help save fuel.

ways to mechanically reduce fuel consumption in cars

Tires

The pressure in all tires should be checked regularly. First of all, it has to do with safety. But here it must be understood that even a slight decrease in pressure can significantly increase fuel consumption (a decrease by 0.5 atm. will increase consumption by 5-6 liters of fuel per year). And if the pressure in the wheel rim is uneven, then fuel consumption will increase by as much as 5%. The same applies if the tread on the tires is badly worn. The driver’s door indicates the optimum pressure for your car.

The lower the pressure in the tires, the more gasoline is spent. If the tires are inflated too much, then their wear will increase and stiffness will increase (you will feel all the delights of our roads more strongly).

Some manufacturers produce energy-efficient tires that cost more than regular tires. Tires have lower rolling resistance, which helps save up to 5% of fuel. For even more savings, you can install lightweight wheels.

To save fuel a little, you can slightly increase the tire pressure (by 0.2-0.3 atm.). This is especially true when the machine carries large loads.

Some people like to put on wide fashionable rims. But the wider the discs, the higher the aerodynamic drag and the higher fuel consumption.

Spark plug

Spark plugs affect the quality of fuel combustion. If it does not burn out completely, then power will drop and gas mileage will increase. Check the spark plugs periodically and change them beforehand. The longer the candles work, the worse the quality of the combustion of the fuel.

It is best to put platinum or iridium candles, the life of which is 4 times longer than conventional ones. They help increase discharge stability and spark gap. As a result, candles work more efficiently even with heavy pollution.

camber adjustment

Every 15-20 thousand kilometers, adjust the camber. On average, this will help save 60 liters of gasoline per year, as well as reduce rubber wear.

Filters

Change the air, cabin and oil filters once a year. If the air filter is not changed on time, the working mixture will be contaminated, which will reduce engine power. In order to somehow compensate for this, fuel consumption will increase. Change filters according to the manufacturer’s recommendations or twice as often when driving on dusty roads.

Engine oil

The better the motor lubricant, the more effectively the friction force is reduced, and this, in turn, reduces the “appetite” of the car. A great engine oil can help save up to 7.5% on fuel. It is best to take a synthetic oil with a reduced viscosity – it will help reduce friction.

check engine

If this indicator lights up on the instrument panel, then you can add up to 50% to fuel consumption. I note that when selling used cars, unscrupulous sellers make sure that it does not burn for some time before buying.

catalytic converter

If this important part fails due to engine failure or low-quality fuel, this will increase fuel consumption by up to 20%. Some simply remove it, especially on very old cars. This savings method will work, but you will be more gassy in the atmosphere.

Remember! If fuel consumption has increased sharply for no apparent reason, then you should immediately contact a specialist to check the important components of the car.

tuning

Chip tuning is designed to increase engine power, but at the same time, there will be rapid engine wear and a multiple increase in fuel consumption.

If you are planning to increase the clearance under shock absorbers or springs, then get ready to spend 8% more fuel.

oxygen sensor

This sensor is very important, it records the combustion efficiency of the fuel and determines how much oxygen remains in the exhaust gas. Over time, the oxygen sensor wears out, and when it breaks, Check Engine appears on the instrument panel. An incorrectly functioning sensor increases fuel consumption by 15%.

The sensor should be replaced on new cars after 150 thousand kilometers, and on old cars (until 1996) every 90 thousand kilometers.

Air duct modification

How to reduce fuel consumption in winter? It is necessary to make sure that the air intake is warm. To do this, you need to remove the air duct. The air will flow already heated (it is collected at the top under the hood). Or remove the pipe at the place of air intake and lower it as close as possible to the motor, where it is even warmer.

Here, the power drops slightly, so in the summer everything needs to be returned to its place. Fuel savings here will be as much as 20%!

ATW Impulse

Such a device is suitable for cars where 12-volt batteries are installed. It is attached to the battery terminals, which helps to speed up their charging. ATW Impulse is especially useful for old batteries, it can restore the plates and increase the service life by 2-3 times. According to the manufacturer, the device will help save 10-20% of fuel.

when to shift gears km/h?

The following gear shifting tips should be followed:

  • First gear pulling away;
  • The second is acceleration;
  • The third is overtaking vehicles;
  • Fourth driving in urban conditions;
  • Fifth (sixth) – driving on the highway.

On the “gears” choose the right gear. If you press the gas to the floor in high gear, then acceleration will be weak, and fuel consumption will be high.

At a speed of 60 km / h, shift to high gear. It also helps when there is almost no gasoline, and the gas station is far away.

Conclusion

Now you know all the existing ways to mechanically reduce fuel consumption in cars. If you follow all the tips together, you can reduce gasoline consumption by up to 30%! Start at least with speed excluding sharp maneuvers and you will notice that fuel consumption will become noticeably less.
