Why is the fuel consumption of cars getting higher and higher?

The car is newly bought and it is very refreshing to drive. The main reason for driving smoothly is to save fuel. But after three or two years of use, the fuel consumption of the car will increase and the power will get worse and worse. Many people can't stand it and directly consider selling it for a new car. This is actually caused by two things we didn't do well in the process of using the car. As long as I do the two points I want to tell you below, the above problems will basically be much better, so that we can maintain the ideal car condition for a long time.

The reason why cars consume a lot of fuel.

Whether the fuel consumption of a car is large or small depends on the displacement of the engine and the training of the engine by the car brand. The displacement of the engine has been determined at the factory, so every new car will be accompanied by a fuel label when it leaves the factory, indicating how many liters the car consumes per 100 kilometers. In general, the smaller the displacement, the lower the fuel consumption of the car, but this is not absolute. For example, the fuel consumption of Japanese cars 1.5L is lower than that of American cars 1.0L, which is mainly due to the different emphasis of various automobile manufacturers on vehicles. Japanese cars pay more attention to the fuel economy of vehicles, so the fuel consumption is lower among their peers.

In the process of daily car use, your car consumes more fuel than other cars in the same car, which is mainly caused by different car habits and engine maintenance. There must be a difference in fuel consumption between violent car owners and slow car owners. It is normal for violent cars to have high fuel consumption. In addition, our engine is an internal combustion engine, and sometimes there is insufficient combustion in the process of burning gasoline. Insufficient combustion will cause carbon deposition inside the engine and affect the fuel consumption of the car. Many car owners are used to heating their cars in situ or using inferior gasoline for a long time. These behaviors will seriously increase the carbon deposition of the engine, and eventually the carbon deposition will make these car owners drive more and more fuel-efficient.

Engine oil has a great influence on fuel consumption.

In addition to carbon deposition, engine oil also has a great influence on fuel consumption. Its impact is mainly long-term, and there is no problem in the short term, but the problem of the influence of engine oil on fuel consumption will appear after driving for three to five years. Many cheap engine oils on the market contain a lot of impurities. The impurities in these engine oils will gradually become sticky sludge inside the engine and attach to various parts of the engine, which will increase the resistance when the engine is running, and then lead to an increase in fuel consumption. This is actually one of the main reasons why many people have been driving for several years and their fuel consumption is getting bigger and bigger.

Two things make fuel consumption more ideal.

First of all, we must pay attention to the maintenance of the engine during the daily use of the car. When I say pay attention to engine maintenance, I don't just mean changing the oil on time. More importantly, try to choose better quality oil. As long as the current car owners know to change the oil on time, the problem of increased fuel consumption will still occur after several years of use, even accompanied by poor engine power. This is mainly because the oil you chose is not good, it is too bad.

The function of engine oil is to lubricate and clean the engine. It is generally believed that tens of thousands of scooters can use more than 100 engine oil casually, and the engine is not that expensive. I didn't know that even the cheapest car, its engine is a precision part. Although cheap engine oil can be used, the above-mentioned sludge problem will occur in long-term use. This cheap engine oil only plays the role of lubrication, but it can't clean the engine. Expensive engine oil is expensive, but it can lubricate the engine and take away the sludge impurities attached to various parts during oil change, thus keeping the engine relatively clean. So whether the car is expensive or cheap, choosing a good engine oil can make your car's fuel consumption and power more ideal.

The second thing is to clean the throttle regularly. Although we disapprove of running to clean the throttle after 10 to 20,000 kilometers, if the throttle is dirty, it will really affect fuel consumption and power. Dirty throttle will cause the computer to be slow and stuck when controlling air intake, which will eventually affect the power and fuel consumption of the engine. Therefore, when there is inexplicable fuel consumption increase and idling jitter, you must first check the throttle and clean it if necessary. I bought a used car. At first, the fuel consumption was high. The urban area is about 13, and even the suburban expressway needs 8 gasoline. But now it's back to normal, with 8 oil in the urban area and 6.5 in the suburbs. I cleaned the accelerator in the process of using the car for 4 months, changed the oil twice and returned to this state. At that time, the throttle was too dirty, and I cleaned it after a thick circle of carbon deposit. I also use SP grade all-synthetic engine oil engine oil.

Avoid pits when buying engine oil.

Many semi-synthetic engine oil in the market are used as the whole of synthetic engine oil. Generally, synthetic engine oil is written on the oil bottle of semi-synthesizer. Many novices don't understand that this kind of engine oil is synthetic engine oil, and they are cheated as a result. The grade of semi-synthetic engine oil is SN, which is better than mineral oil. As long as there is no word "all synthetic" on the bottle of engine oil, it is definitely not all of synthetic engine oil. The real synthetic engine oil is SP grade, and its name is Quansynthetic engine oil directly, which is generally more expensive than semi-synthetic engine oil. Everyone must pay attention to avoiding pits when changing oil.
