Why does the average fuel consumption of Toyota Corolla sedan increase after changing the engine oil

It is normal for fuel consumption to increase after an oil change.

Most of the new cars of Toyota Corolla are replaced by default Toyota pure brand 0w-20 fully synthetic engine oil, which only needs to be replaced once a year or 10,000 kilometers. Synthetic oils have a wider temperature range, longer service life, and higher costs. With the same oil film requirements, synthetic oils can achieve lower viscosity.

Toyota Corolla uses the official recommended oil of 0w w w w-30, and 0w in 20w-0 indicates the cold cranking performance of this oil. It is easier to start the engine in cold weather with a lower w-20 oil, the w in 0w-20 indicates the viscosity characteristics of the oil at high temperatures, and a high viscosity (higher value) oil may be more suitable for high-speed or heavy-duty vehicles.

Choose the viscosity label, generally in winter, most areas can use 5W, and some areas in the north (such as Harbin) are best to use 0W, low temperature mobility is stronger, adapt to the driving environment temperature. For high temperature viscosity, the viscosity of lubricating oil is generally 20. However, if the vehicle is often driven on congested roads, the vehicle is relatively old, and the heavy vehicle is transported for long distances, the viscosity of the lubricating oil can be appropriately increased, such as using 0w30 engine oil.

The oil used in self-priming engines is of average quality and can be used with mineral oil and semi-synthetic oil. If you have a big budget, you can use a fully synthetic motor oil. Compared with self-priming engines, turbocharged engines have more precise engines, more demanding operating conditions, more advanced lubricants, better oil fluidity, and the best performance among synthetic oils.

For the choice of engine oil brand, if you need to use engine oil for a long time, you can choose Mobil oil. Pay attention to the cleanliness of the oil, you can use Shell oil; If you need an oil with strong film toughness, you can choose Castrol. For example, turbocharged engines are prone to carbon deposits at high speeds, so you can choose Shell synthetic engine oil with strong cleaning performance.

Most of the old and new cars of the Corolla Pi are the default settings to replace the pure brand 0w-20 full-generation engine oil of Toyota cars, which must only be replaced once a year or 10,000 kilometers. Synthetic motor oil is used at a wider temperature, has a longer application time, and has a higher cost; The same oil slick stipulates that synthetic motor oil can be achieved with a lower viscosity.

Corolla with the official website strongly recommends the application of 0w-20, 5w-20, 5w-30 and 10w-30 model oil, 0w in 0w-20 indicates the performance of oil cold start. The use of a motor oil with a lower front value can make it easier to start the car engine in severe cold climates. 20 in 0w-20 indicates the viscosity characteristics of the engine oil at continuous high temperatures, and the high viscosity oil (with higher values) is likely to be more suitable for cars or lightly loaded cars.

The selection of viscosity models, generally in the case of the winter dust season, the vast majority of regions can apply 5W, while some regions in the northern region (such as Harbin City) try to apply 0W, which has stronger low-temperature circulation to integrate into the working temperature of safe driving. For high temperature viscosity, the viscosity value of grease is generally 20, but if it is often driven safely on congested roads, the car is very old, and the long-distance freight is light-loaded vehicles, etc., the viscosity of grease can be reasonably improved, such as the application of 0w30 engine oil.

The self-priming module uses a mediocre oil and can be used with mineral oil, semi-synthetic oil, and if the cost budget is large, it can be used with full generation oil. Turbocharger automobile engine is relatively self-priming, its automobile engine is more precise, the working standards are more stringent, the applied grease refined oil is more advanced, must have good flow of oil, and it is best to generate all engine oil.

For the selection of well-known brands of engine oil, it is necessary to have a high-efficiency engine oil, which can be selected Castrol engine oil; Pay attention to the cleaning of engine oil to the automobile engine, and choose Shell engine oil; If you need to choose a motor oil with strong slick ductility, you can choose Castrol. For example, the turbocharger module, which is prone to carbon deposits at high speeds, allows for the selection of Shell oil full generation oil with strong cleaning performance.

Summary. Hello, the new car is in the run-in period. None of the fuel consumption is at its minimum.

What conditions are you driving your Corolla now, which should be about 6 gases at high speeds? There will be 8 commutes in urban areas, and 8 or even 9 commutes will be driven for long and short distances. Could you please give me a rough description of the working conditions you are using?

It's how you're using the car.

Fuel consumption 8-9, what's going on?

Hello, the new car is in the run-in period. Fuel consumption has not reached the lowest level. What conditions are you driving your Corolla now, which should be about 6 gases at high speeds?

There are 8 commutes in urban areas and 8 or even 9 commutes in long-term short distances. Could you please give me a rough description of the working conditions you use? It's how you're using the car.

And one more important point. You're talking about about 9 oils. You saw it on the gauge, because he was a new car.

100 kilometers of fuel consumption is a need to be corrected by non-stop driving. It is recommended that you do not pay attention to the problem of fuel consumption before you have done the first insurance. After the first insurance, you can go for a run, crack the high speed.

Used in the city without congestion, one kilometer piece, is a new Corolla car. It is just 8,000 kilometers, which is twice the fuel consumption of Tianlai.

I'm driving a Carlo Elimination Pull, too. It is the owner of the first batch. Driving in the suburbs, it is now about 7.

You should now go to a 4S shop to check the high-pressure oil pump. Corolla has a common problem of leaking large high-pressure oil pumps from Shenqiao. Some of the gasoline is not burned, but goes directly into the engine oil.

Summary. This possibility leads to a lot of things, you look at the vehicle for a long time has not replaced the air filter, gasoline filter, oil and oil filter, tire pressure is abnormal, the oil is not filled according to the specified number or the fuel is not filled according to the specified number, the throttle has not been cleaned for a long time or the spark plug is replaced according to the maintenance interval, etc.

This possibility leads to more, you look at the vehicle long which time has not replaced the air filter closed, gasoline filter, oil and oil filter, wheel and plum tire pressure is abnormal, the oil is not filled according to the specified number or the fuel is not filled according to the specified number, the throttle has not been cleaned for a long time or the spark plug is replaced according to the maintenance cycle, etc.

The oil filter was changed, but the air filter was not.

It is only more than 7,000 kilometers away.

Now the fuel consumption is as high as.

The main thing is that the air joint door needs to be cleaned.

Last year, the car oil was scraped by the paint of the year, and I went to the repair shop to repair the buried thoughts, when my car bent the button seemed to be moved by the repair shop, and the fuel consumption slowly increased after the car came back, from now on.

I wonder if it's the ghost of the repair shop?

This is indeed very possible, and it is impossible to increase it so much.

What should I do?

Go directly to the 4S store to check and open a report.

Toyota Corolla engine oil can choose the original ** brand engine oil: 0w-20 fully synthetic engine oil 4L 400 yuan, 5w-30 fully synthetic engine oil more than 200, Toyota Corolla uses the most recommended 0w w w w-30 and other brands of engine oil, in addition to the original engine oil, you can also choose Shell, Mobil, Castrol and other brands.

In addition to genuine engine oil, Corolla can also choose from engine oil brands such as Shell, Mobil, Castrol, etc. If you use SAE10W-30 or higher viscosity oil in cold weather, it may be difficult for the engine to start, because the SAE0W W20 or 5W30 machine is recommended in the northern region. The use of 0w-20 engine oil can maximize fuel savings.

When choosing an engine oil, it is necessary to strictly follow the level of engine oil specified in the instruction manual of the car in Togaso. If you don't have the same level of oil, you can use a higher grade of oil, but never use a lower one. At present, the engine oil on the market, simply put, can be divided into mineral oil and synthetic oil because of the different base oils.

Synthetic oils are divided into fully synthetic oils and semi-synthetic oils. Synthetic motor oil is of the highest grade.

Millions of car purchase subsidies.

In most cases, the oil change of the family car is about 4L each time, so a barrel of oil is also the most common with a capacity of 4L, and the car oil is not changed by how many percent, but the oil needs to be changed according to the mileage, generally 5000 kilometers to change once.

Generally, there are 3 types of engine oils, fully synthetic, semi-synthetic, and mineral engine oils. Generally, fully synthetic engine oil is changed every 10,000 km or 1 year. Generally, semi-synthetic engine oil is changed every 7500 km or 7-8 months.

The general mineral oil is changed every 5000 km or 6 months.
