Listed for sure Hello top 10, most common reasons for hi. I am dr. Cool autofix in this brief but yet most comprehensive video. I will be teaching you top 10 most common cause of high fuel consumption in your car and how to fix it.
needless to tell you to subscribe to my channel like or share, cause it makes no sense if I am actually teaching human on how to fix their car problems. If you try to group all possible causes of increased fuel consumption, then there will be only two of them. First, the engine is running inefficiently due to Mechanical or electrical electronics factors. Simply put some of the gasoline diesel or gas is wasted. The second Global reason is, when something interferes with the movement of the car, that is, there is some harmful resistance to overcome which the engine Burns additional fuel. But there is also one unique reason that does not belong to any of the group's described. Let's start with her,
1. low-quality fuel, the lower the quality of the gasoline, the Higher consumption, a very common cause of increased fuel consumption at all times of the existence of the car. Poor-quality fuel is sometimes filled. Even at the most trusted gas stations that you visit regularly at random gas stations, the come across on the highway during long trips. Oops, stumbling upon pulley, burning gasoline or diesel fuel turning into jelly is generally a common thing. The biggest problem with this cause is that it is almost never noticed, immediately after refueling as a rule, if the fuel is not of completely disgusting quality, the overrun is noticed after many kilometers sometimes low quality gasoline makes itself felt at all on the second day. In such cases, few people begin to sin at the gas station. Blaming the car or secondary factors for the increased consumption. This reason also has an advantage, The increased consumption disappears when low quality fuel is produced or its concentration in the tank decreases due to refueling with a new portion. That is why only with regular accounting can you start to panic about overspending you know exactly what the average fuel consumption should be under certain circumstances and if the numbers increase between You will immediately understand what is the reason in addition to the quality of the fuel, its consumption is also affected by the octane number, if it is gasoline. For example, if the engine of your car is designed for the 95th and you decide to save money. They 92nd you are guaranteed, an increased consumption as a rule. The problem is accompanied by a decrease in throttle response and other signs of unsuitable fuel.
2. Aggressive driving. One of the most common causes of increased fuel consumption is aggressive driving, Driving aggressively and calm driving are teo distinctive different thing, driving are understood by many in different ways. The Border looks like this, an aggressive driver starts. Bristly from a standstill turns the engine up to four to five thousand revolutions to switch to the next gear, Maintains a high speed to the last and then intensively works out the brakes. The other driver starts to drive smoothly does not press his foot hard flooring the gas shifts gears at the lowest possible speed sees the stopping place in advance. Releases the gas in a timely manner uses engine braking more than the main breaks at the same time. The second fuel consumption per 100 kilometers is 7 meters and the first has 15 liters and kept driving is a separate topic which cannot be studied within the framework of this video.
It'e best to leave only a few of this infos, relying on which those who are curios will expand their knowledge.
3. overload by using system features like AC or Towing trailers. Your things will not move from point A to point B for free, an increase in the mass of the car directly affects the increase in fuel consumption. Everything is extremely simple here to move any load, you need to spend energy and the heavier this, Slowed, the more energy is needed. Only fuel consumption increases. It is believed that every additional 100 kilograms of weight. Carried, increases gasoline, consumption by 10%, That is the four people are sitting in the cabin accept you as the driver. Plus, the trunk is loaded with some things. Then fuel consumption can easily increase one and a half times from the nominal.
4. clogged air filter, if the engine does not have enough air, It runs on a rich mixture, The condition of the air filter effects, how much air will flow into the fuel mixture preparation system. If the air filter is clogged with dust, dirt, leaves, insects and has not changed for several tens of thousands of kilometers, fuel consumption can increase up to 50%. Meanwhile, many motorists. Do not even know where this filter is or simply. Forget about its existence under the hood under normal vehicle. Operating conditions, it is Amended to change the air filter to a new one, every 20,000 kilometers. If the car is often in Dusty, areas used to drive through forests, dirt roads. And so on, replacement may be required every 5,000 kilometers. Fortunately, it costs a penny. Therefore, do not neglect these recommendations. Moreover, you will then save the money. Spent on the filter on fuel
5. driving on low tire pressure, the lower the presure in the tires, the harder it is for the engine to push the car and the more it consumes fuel. When the air pressure in the wheels of a car is below normal. The contact patch changes significantly, this is the area where the tire is constantly in contact with the road surface. The larger, the area of this same contact patch, the higher the resistance of the rolling friction force. And this in turn means that it is harder for the engine to push the car forward accordingly, more fuel is required for a particular mileage. Normal tire pressure for each vehicle is indicated in the owners manual. Many people intentionally inflate their tires with high pressure, which of course allows you to save a little on fuel. However, such savings are not worthwhile since over inflated tires wear out Faster. In addition, it should be remembered. The two smaller. Contact patch adversely affects the Chuckles handling in particular, the braking distance increases as well, as the risk of drift or skidding. When maneuvering
6. bad coolant temperature sensor or driving on a cold engine, if we take the increased fuel consumption into mind, then driving on an unheated engine can be neglected today driving a cold engine and driving with a bad coolant temperature. Have nearly similar fuel consumption only that, there are often opinions that modern engines, do not need warming. And this does not affect fuel consumption in any way which is not true. Over the past 20 years, Technology has changed remarkably, Motors are made not from cast iron, but from aluminum, the thickness of the parts has decreased and they warm up much faster than before. But even the most modern engine, is not able to reach operating temperature Instantly, it takes at least five minutes, even in the summer, in the meantime. The engine is cold it consumes, more fuel than is written by the manufacturer in the technical specifications. If the car is evolved years of production, and it's not yet, some are outside, then, reaching the operating temperature and the most economical consumption takes more than 15 minutes. This is a proven fact, which is simply useless to dispute. Quite visual tests have recently appeared on the web proving that an unheated engine is a good reason for increased fuel. Consumption. If your car is having a bad coolant temperature sensor, that will be worst of all.
7. driving on winter tires. In summer winter, tires are softer and therefore create additional resistance either in pursuit of dubious savings or simply because of a lack of money for the roads are full of cars. Shot in winter tires, in summer, however, tires for winter user made of soft rubber and also have a higher tread with a fine detail. Latin all this impaired. Rolling on hard surfaces respectively, resists movement, as a result fuel consumption Goes Up In fairness, it should be said that driving in the summer on winter tires. Does not increase fuel consumption, very much approximately, three to five percent but here we must also take into account that winter tires, become too soft in summer, which increases the braking distance and worsens. The cars handling that is it is also unsafe that why Why in some Western countries, it's an offence to Cross Drive tires for regardless of it primary objective.
8. defective turbo. If your car is not natural, aspirated engine, it's turbocharged. Turbo is used to engine the engine power and improve fuel economy, when your turbo lag or failed, lots of things kicked in and one of those is a poor gas mileage due to that fact, the engine will lost 40% if it Powerhouse critical components that improved it power output. The replacement of the turbo will be best fix under this condition worn out, clutch and warming. The car in the morning.
9. problems with the ignition system. If gasoline, ignites, early late or every other time, some of it simply flies out into the pipe. This reason applies only to gasoline engines, including those who work together with HBO, there may be several problems too, early or late ignition large or small gap between the electrode. So the spark plugs incorrectly timed engine exhaust leaks. Defective catalytic converter, failed or triggered candles every other time. Punched high-voltage, wires failures in the computer. Bad spark, plug bad ignition, coil resulting into engine misfire in order for a gasoline engine to operate at maximum efficiency and consume a minimum of fuel. The spark must be timely and powerful enough. And in each of the cylinders, if one of the conditions is not met fuel consumption, increases.
10. problems with the air fuel system, air fuel mixture, preparation is a critical process for its work. Any internal combustion engine uses. Not only fuel, but also are. And now the consumption directly depends on the proportions and quantities in which the air-fuel mixture is supplied to the cylinders.
It can be called Baretta or injection for diesels. This is done by the injection pump. In modern engines, electronics are responsible for the operation of the fuel system. The ECM in turn focuses on the signals of a dozen sensors. Failure of any of them can cause increased fuel consumption. Such as MAF sensor oxygen sensor, intake air temperature, sensor, bad or clogged injectors, bad fuel pump or clogged Fuel filter, but throttle position sensor, throttle body or bad carburetor in carbureted engines, everything is much simpler and clearer unlike computerized system. That is non carburetted in carburetor systems. The main thing there is to properly adjust the preparation of the air-fuel mixture before it hits the combustion chamber, as well as keep the Jets clean, if your car is from 1996 to date. You can hook up a scan tool with your car to pull out trouble codes Stored in your ECM, This are the most commonly cause of higher fuel consumption in your car and didn't get out the above listed factors.
