Drivers are struggling with the eternal problem: how to pay less for fuel? They tried dozens of different methods, new equipment, driving techniques, fuel additives, and equipment. Which of these things works and what does not?
If we are confident that we have bought something that will certainly reduce fuel consumption because this is confirmed by the research, let us ask ourselves an important question – does it work well enough to buy a given product to us a real financial benefit?
Fuer saver tires
A good example is tires advertised as lower rolling resistance tires or even referred to as fuel saver. Who pays to buy them? Let’s count. Low-resistance tires, according to their manufacturers, reduce fuel consumption by 3-5%. Sounds good, but let’s see what that means in reality. Of course, the data provided by tire companies cannot be questioned, especially as their tests have to tell the truth. However, they can be carried out under specific conditions. This means that the reduction in combustion is possible in certain situations – at a certain speed, temperature, surface, etc. Let’s assume that we can still save 3% of the fuel, ie 3 liters of 100 liters. to a hundred. It follows that we can run 1400 km and spend 450 pounds on the assumption that liter of fuel costs 4.5 pounds. If we save this 3 l of fuel, we will be 13.5 pounds forward. The same effect will reduce fuel prices by 13.5 gr per liter. At a distance of 10 thousand. We save about 100 pounds. A lot? Not necessarily. If the fuel save tires cost the same as we would normally spend – we save. If we drive a lot – we save. In no case else.
As for tires, even the best fuel savers will not do anything unless they are properly inflated. The most common mistake of Polish drivers is to drive with undue pressure in tires, generally too low. A simple tire – with a low tire pressure of 0.1 b, which means a 1% increase in fuel consumption. 0.2 bis 2% and so on. And that’s how we lose the whole effect we could get with fuel-efficient tires. Perhaps it would be better to invest in a good pressure gauge and compressor to keep the regular pressure on the tires.
Oil and spark plugs
Are you regularly replacing engine oil in your car? If so, the car burns normal fuel. But if you forget to replace or ignore it, burning can increase by 2-3%. The same is true with spark plugs – regular replacement is a guarantee of decent fuel economy. This also affects the air filter.
Many drivers like to install larger tires on their vehicles than recommended by the manufacturer, and nice design rims. Well, the wider the tire, the better the grip, but also the combustion. Nice rims have that to themselves that they often weigh more than serial, and by that … yes, you guessed – they increase fuel consumption.
You should throw away all the unnecessary things from the car. Many drivers carry unnecessary things in their luggage. Stocks of washer fluid, rectifiers, starter cables, etc. I know those who do not want to dismantle the roof rack and carry air in it. And such a box puts a lot of air resistance and significantly increases combustion. If we want to lower it, remember to use proper air conditioning and electrical appliances, such as heated seats. Let’s not turn them all at once. Then they consume the most electricity, and therefore the fuel.
Bet on eco-driving
At the end good news. Do you know that burning can be reduced by up to 40%? Just go quietly and follow the rules of eco-driving. Contrary to appearances it does not necessarily mean “boring and slow”. But definitely cheaper.
