If you only change the engine oil once a year, when is the best time to change it?

Friend; It doesn't matter what brand of oil you're using; It is no problem to change the engine oil regularly by looking at the number of kilometers; But; 1] Change once a year; Isn't it a bit long? Do you see the oil in the dipstick? Isn't it dark; There's still a certain amount of transparency; Three or four thousand kilometers should be replaced; There are also three filters; Whether it should be replaced or not will affect the life of the engine; 2] From a human point of view; It is still the best to change in spring and autumn; There is a gutter just right; There are no gutters; You need to drive the car to a broken road; or the front wheel is raised; The oil is clean; [including three filters]; Spring and autumn days will not be full of stinky sweat; In winter, it is not easy to clean up and freeze hands and feet; Wear a lot; It's not good to get off the tool; Isn't it; OK, did I understand; Don't be reluctant to change; You treat it well; It will treat you well, too; You know;

It is best to change the engine oil every six months, even if it runs very little, it has nothing to do with what oil is used, the engine oil is exposed to the air, and the performance has attenuation and oxidation, so even if it is not used, as long as it is opened, it cannot be stored for a long time.

Engine oil also has a shelf life (like food, unopened packaging may not be bad within 1 year, once opened 3 days to rot), although it is fully synthetic technology oil grid indicators to extend, but the internal working conditions of the engine are poor, long-term parking oil will also due to factors such as sourness and itching, performance decline, conditions allow it to be replaced for half a year.

Changing the petrol all depends on your driving habits. If you're driving no more than 10 miles or less in general, you should consider changing your oil more often, rather than every 3,000 miles.

Car oil should generally be changed after 5,000 kilometers. The worst of the engine oil has a greater impact on the working environment of the engine. The engine works in a high-temperature environment, and the mechanical friction movement is constantly repeated, and the engine oil plays a role in cooling, lubrication and cleaning in this project.

Over time, there are more impurities in the oil, and the performance decreases.

Combined with the quality of domestic oil products, the oil can be changed at about 8,000 kilometers, which is a more appropriate time. However, 8 thousand kilometers to change the oil, is not suitable for all cases. Depending on the quality of the engine oil and the different road conditions, the replacement time will fluctuate.

Fully synthetic engine oil has the longest service life, and it can generally be replaced in about 10,000 kilometers if fully synthetic is used. Semi-synthetic oil can be changed up to 8,000 km. Ordinary mineral oil is recommended in advance.

Mineral oil needs to be replaced in six months, maybe 5,000 kilometers, while semi-synthetic oil needs to be replaced in six to eight months.

Yes, the car oil should be changed about once in half a year or 5000 kilometers, and it can be changed every time these maintenance are carried out.

If you usually drive less, you will change it once every six months, ordinary oil will be changed once every 3-4 months for 5000 kilometers, and fully synthetic oil will be changed once for 7000 kilometers in 6-9 months. More according to the book, some brands require 2 months within 3000 kilometers, and some require 7500 kilometers within 6 months.

I think it should be changed once a year, if it is changed once every six months, it is not necessary, and it will damage the engine, so I think it should be changed once a year.

Hello, the engine needs to be guaranteed to change the oil at least once a year. If you travel a small number of kilometers, it is recommended to use semi-synthetic. The maintenance interval is 7500 kilometers or once a year, I wish you a happy car!

If the engine of this car is in good condition, yes. 1。Maintenance once a year should not be a big problem, first of all, to ensure that the mileage does not exceed 5000 kilometers, followed by the quality and grade of the oil you use, the highest level of which can of course extend the time of oil change; 2。

If you use general engine oil, then you should always check the quality of the engine oil, and poor oil lubrication will damage the vehicle; 3。If the car has been parked for 1 year and has not moved for a long time, the oil filter should be replaced in time when it is unsealed and used. Engine oil is a necessary lubricant to ensure the normal operation of the engine, its specific role is to lubricate metal parts, reduce the friction between parts, take away the huge heat generated by the engine when doing work, clean the fine metal chips produced after wear, as well as sealing, shock absorption, rust prevention and other functions, so choose a suitable oil for your car to directly know that it will affect the service life of the whole vehicle.

The oil change interval standards for different engine oils are as follows: mineral oil 5000km, semi-synthetic engine oil 7500km, fully synthetic engine oil 10000km; Or half a year. The above two conditions come first!

Engine oil is generally divided into three types: mineral oil, semi-synthetic engine oil, and fully synthetic engine oil, and its lubrication effect, thermal stability, oxidation resistance, wear resistance and other properties range from low to high.

The mileage and time are based on the first come, which means that if the engine is added with mineral oil, even if the engine has not been running for six months, then the oil should be changed, because the mineral oil has oxidized and deteriorated in six months, and has lost a lot of its due performance.

Why change engine oil?

As the powertrain of the car, the engine will produce friction when the piston movement is working, and the gasoline will deflagrate in the cylinder, and the temperature in the engine will be as high as 600, and it will also rub to produce waste such as metal particles.

When the engine works in this extremely harsh environment, the engine oil plays a role in lubricating, cooling, and cleaning the swag generated by the friction of the engine, ensuring the normal operation of the engine and prolonging the life of the engine. Therefore, the role of engine oil in the normal operation and prolongation of the service life of the engine is very important.

However, unlike blood, engine oil has a self-purifying effect, and over time, the oil will be mixed with various wastes, which need to be released, so it is necessary to replace the oil regularly.

Summary. Hello dear, it is good to change the engine oil once every 6 months. The reason is that the engine works in this extremely inferior environment, and the engine oil plays a role in lubricating, cooling, and cleaning the stolen goods generated by the friction of the engine, ensuring the normal operation of the engine and prolonging the service time of the engine.

Therefore, the role of engine oil in the normal operation of the engine and the extension of service life is very important. <>

It is best to change the oil <> every few months.

The reason is that the engine works in this extremely inferior environment, and the engine oil plays a role in lubricating, cooling, and cleaning the stolen goods generated by the friction of the engine, ensuring the normal operation of the engine and prolonging the service life of the engine. Therefore, oil cracking is very important for the normal operation of the engine and the prolongation of service life.

Singing the praises of the heart].

The functions of engine oil are: 1. Lubrication, 2. Auxiliary cooling and cooling, 3. Cleaning and cleaning, 4. Sealing and leakage-proof, 5. Anti-rust and anti-corrosion, 6. Shock absorption, buffering, and anti-wear. Engine oil, also known as engine lubrication oil, is composed of base oil and additives.

Engine oil is divided into 1, four-stroke oil, 2, two-stroke oil. <>

<> the maintenance of car oil is to change according to the mileage, you can also check the quality of the oil, if you use the general crack oil, then you must always check the quality of the oil, the oil lubrication is not good to the vehicle will be damaged. When the machine hole source Kai oil is used for half a year, check once a month or before going out of the car, take out some oil from the oil dipstick, look at the oil level and the quality of the oil, feel okay and continue to use, and replace it immediately if the quality is poor, so that the degree of damage to the car will be reduced. <>
