Can I change to semi synthetic motor oil if I use a fully synthetic motor oil?

The YACCO engine oil brand believes that there is no big problem in general, and the oil selection should be purchased from a big brand as soon as possible

Synthetic motor oil is a kind of artificially manufactured motor oil, in the production process, a variety of natural substances are selected for chemical decomposition, and then synthesized with various other substances, and finally synthetic motor oil is produced.

The synthetic motor oil is of better quality and will be noticeably felt in the following aspects: the cold start is smoother, especially in the Northeast; More fuel savings; The oil change interval is longer, which is equivalent to times or longer than ordinary lubricating oil; Extend engine life and reduce maintenance; Due to the superior cleanliness of synthetic oil, the engine block is much cleaner.

Semi-synthetic engine oil and fully synthetic engine oil are two classifications of engine oil, the biggest difference between the two is that fully synthetic oil is used at a wider temperature and has a longer service life; The same oil film requirements can be achieved with a lower viscosity of synthetic oils, while semi-synthetic oils need to use a higher viscosity than synthetic oils to achieve such requirements. In other words, in the same operating environment, a fully synthetic oil can protect the engine with a lower viscosity. Similarly, in the same working environment, fully synthetic oil has a much longer service life than semi-synthetic oil, so although the cost is higher, it is not much higher than mineral oil after comparing the number of oil changes.

Synthetic motor oil features:

1. Fully synthetic engine oil has better high and low temperature performance.

2. There is a longer oil change interval.

3. Suitable for worse vehicle conditions.

Generally speaking, you can choose according to the requirements on the maintenance manual, which can meet the needs of the car, if the budget allows, it is recommended to use semi-synthetic engine oil, if you want to spend money on upgrades, the difference you need to remember is that the maintenance cycle.

In general, mineral oil is changed every 5,000 km, semi-synthetic oil is changed every 7,500 km, and fully synthetic oil is changed every 10,000 km.

Hope it helps, hope!

Let's talk about buying a car, using a car, maintaining a car, and repairing a car.

It is possible to change to semi-synthetic oil, but it is not recommended.

Because fully synthetic motor oil lubricates better than fully synthetic motor oil, if you change fully synthetic motor oil to semi-synthetic motor oil, it will affect the wear and tear of the internal parts of the engine. Because semi-synthetic oil is not as good as fully synthetic lubricating oil, it is not recommended to change it in this way.

If you want to change it, you need to clean the oil inside the engine from the previous one.

Hope it helps, hope, thank you!

Hello, the current number of people consulted may not reply in a timely manner, if it is a vehicle failure problem, it is recommended to use the computer to detect the specific cause of the failure, search for "car master" can consult car problems at any time, 24 hours ** answer.

What car? It is best not to use semi-synthetic oil for supercharged engines, and it is best not to use semi-synthetic oil for supercharged engines, because semi-synthetic oil decays quickly, which is not good for turbochargers and is easy to damage.

Self-priming engines can be run with semi-synthetic oil.

Yes, try to synthesize it as much as possible, and if you use it, it doesn't matter.

Yes. The maintenance interval is 5000km once for half a year, and the full synthesis can be a little longer.

Dear, this question is up to me, it takes a little time to type, please be patient, thank you!

Hello, Happy New Year, dear, the car master for your service, attentive, careful, attentive to answer your car questions, for you to find the corresponding problem solutions and solutions, will provide you with a satisfactory answer! We hope you find this answer helpful. Happy Chinese New Year, Happy Year of the Tiger Hello, car engine oil fully synthetic and semi-synthetic engine oil can be replaced with use, there is no problem first, this depends on what engine, if the engine requires the use of fully synthetic engine oil, this is best to use fully synthetic engine oil Second, there is a certain difference between the additive composition of fully synthetic engine oil and semi-synthetic engine oil, and the replacement cycle is not the same Third, the replacement cycle of fully synthetic engine oil is one year or 10,000 and a half kilometers, The synthetic oil change interval is 7,500 km, or eight months.

Semi-synthetic motor oil can be replaced with fully synthetic because:

1. Due to the essential difference between fully synthetic engine oil and semi-synthetic engine oil, after replacing semi-synthetic engine oil, the number of kilometers of oil maintenance should be appropriately adjusted according to driving habits and actual road conditions. Under normal circumstances, the replacement cycle of fully synthetic engine oil is about 10,000 kilometers, and the replacement cycle of semi-synthetic engine oil is about 7,000 kilometers;

2. Because of the different engine manufacturing processes, they are different in terms of internal structure and quality precision. Especially like some high-end models, the more sophisticated the inside of the engine, it needs better fully synthetic oil for lubrication. Therefore, we should check whether it is suitable for semi-synthetic engine oil according to the instructions in the car instruction manual;

3. Although you can change back to semi-synthetic engine oil after using fully synthetic engine oil, it is still recommended that you use fully synthetic engine oil. Because compared with semi-synthetic engine oil, fully synthetic engine oil is better in terms of high and low temperature fluidity, replacement cycle and adaptation to harsh vehicle conditions, etc., and even combined with the best factors and replacement cycle, fully synthetic engine oil will be more cost-effective.

Yes, the difference between fully synthetic and semi-synthetic oil is the difference in kilometers, as long as you don't buy fake oil.

In China, fully synthetic engine oil can generally run up to 10,000 kilometers, semi-synthetic engine oil can run up to 7,000 kilometers, and ordinary engine oil can run up to 5,000 kilometers. This is a standard for the number of oil roads, if in the city with a small amount of clean dust can exceed 1000-1500 kilometers, the oil change is to say the purity and viscosity of the oil, in the dirtier city you have to change the oil regularly according to the above standards.

The difference between fully synthetic and semi-synthetic motor oil is:Base oilsDifferent, different replacement cycles, different applicable temperatures, different applicable vehicle conditions, different use of slow additives, and different protection of the engine.

1. The base oil is different

Semi-synthetic motor oils use Group 3 base oils; Fully synthetic motor oil is used.

Class III, IV and V base oils are blended. Fully synthetic motor oils are one grade higher than semi-synthetic motor oils in the selection and sale of base oils.

2. The replacement cycle is different

Semi-synthetic engine oil should be replaced once every six months or 7,500 kilometers during use; Fully synthetic engine oil is changed once a year or 10,000 kilometers during use. Of course, the specific engine oil should be changed according to the specific replacement cycle.

3. The applicable temperature is different

Fully synthetic engine oil can be used at a wider temperature, and in the same working environment, fully synthetic oil can achieve the purpose of protecting the engine with a lower viscosity, while semi-synthetic engine oil has relatively high requirements.

4. The applicable vehicle conditions are different

Semi-synthetic engine oil is more suitable for economical, small displacement and smooth driving models; Fully synthetic engine oil can be used in a variety of harsh and harsh conditions, with better resistance to high temperature and low temperature, and is more used in turbocharged engine models and high-end models.

5. Different additives used

The additives used in fully synthetic motor oils have a high content of TBN, which makes the oil last longer and cleans the engine; Semi-synthetic motor oils use additives with low levels of TBN and shortened oil maintenance intervals, resulting in sulfide salt ash.

6. The protection of the engine is different

Fully synthetic motor oil is better than semi-synthetic motor oil in terms of performance, so fully synthetic motor oil is better than semi-synthetic motor oil in protecting the engine and cleaning the inside of the engine closure.

Car oil change fully synthetic engine oil is better.

1. Automobile engine lubricants are simply divided into mineral oil, semi-synthetic engine oil, and fully synthetic engine oil, and the base oil, raw materials, and additives of engine lubricating oil are not the same.

2. How to save money and be more assured when replacing automobile engine lubricating oil, automobile engine lubricating oil selection is in accordance with the vehicle maintenance and repair manual for reference, automobile engine lubricant selection is not the more expensive the better, but the more suitable the better, not necessarily the most expensive "local tyrant friends at will", choose the right oil at the right price.

3. Mineral oil for naturally aspirated engines is generally 5000 kilometers and 180 days "once every six months", semi-synthetic engine oil for naturally aspirated engines is generally 7500 kilometers and 180 days "once a half year", fully synthetic engine oil for naturally aspirated engines is generally maintained once a year for 10000 kilometers, turbocharged engines have stricter requirements for engine lubricating oil performance, and turbocharged engines are generally recommended to be maintained once every 180 days for 5000 kilometers.

4. Semi-synthetic engine oil and fully synthetic engine oil additives and additive types are different, base oil composition is also different, fully synthetic engine oil has better wear resistance than semi-synthetic oil and stronger oxidation resistance, fully synthetic engine oil performance is better than semi-synthetic, of course, fully synthetic engine oil is more expensive than semi-synthetic engine oil. The best choice of car engine lubricant is not the most expensive, the best "local tyrant exception".

Personally, I think that if you change the engine oil, it is better to choose fully synthetic engine oil, and the density of fully synthetic engine oil is better, so it is better for engine maintenance.

If you change the engine oil, of course, it is better to choose a fully synthetic engine oil, because the oil is changed once a year or once every 10,000 kilometers, and the viscosity of the fully synthetic engine oil is relatively high, which can enhance the power of the engine and reduce wear.

The oil change should be more fully synthetic, I think fully synthetic oil. It should be better and more conducive to the model.

Change the oil grid continuously to change the fully synthetic engine oil, and the corresponding ** of the fully synthetic engine oil should be higher, but he runs more mileage, and it is clean, and it is also very protective of the car.

Semi-synthetic engine oil can be used for daily maintenance, Mobil and Shell engine oil are good, and the car maintenance cost is lower, of course, it will be better to use fully synthetic engine oil.

No, there is no mineral oil in the fully synthetic engine oil, there is generally a small amount of mineral oil in the semi-synthetic engine oil, the temperature of the fully synthetic oil is wider, the service life is longer, if it is mixed together, it will reduce the service life, and the viscosity of these two types of engine oil is also different, and the protective effect of the machine is also different.

The same oil film requirements, synthetic oil can be achieved with a lower viscosity, and semi-synthetic oil needs to be used relative to the synthetic oil to achieve such a requirement, fully synthetic oil compared with semi-synthetic oil: fully synthetic oil has better high and low temperature performance, longer oil change cycle, suitable for worse car conditions, if mixed together will pull down the efficiency of the limbs.

It's not the same, fully synthetic engine oil is changed once a year for 10,000 kilometers, and semi-synthetic engine oil is changed for 7,000 kilometers or once every six months.

Fully synthetic engine oil is generally 10,000 to 12,000 kilometers and then replaced, semi-synthetic engine oil is 7,000 to 8,000, the difference is still quite big, but fully synthetic engine oil is more expensive than semi-synthetic engine oil, good cars are recommended to add full synthesis, but local tyrants are different!

Many novice drivers don't know how often to change the fully synthetic engine oil, in fact, the oil change cycle of the fully synthetic oil and the semi-synthetic oil is not the same, it is longer than the semi-synthetic oil, the general recommendation is 8000-10000 kilometers to change once, if you drive less to change once a year. In addition, how often to change the fully synthetic engine oil has a certain relationship with the environment, if the long-term dust is large, often run short distances, it is recommended to shorten the replacement cycle. I myself use Shell Helix Ultra, which is often referred to as gray shell, this oil is made using PurePlus natural gas-to-oil technology, the stability is particularly good, even if the environment is not good, 10,000 kilometers of oil change is not a big problem, you can also try.

<> fully synthetic motor oil may not be suitable for changing to semi-synthetic:

1. Semi-synthetic engine oil, it is.

The second and third types of base oil are blended in proportion, and then additives are added to a mixed product, which is more expensive than mineral engine oil, and the performance is not as good as fully synthetic engine oil.

2. The biggest difference between the two is that the temperature of fully synthetic oil is wider and the service life is longer; For the same oil film requirements, synthetic oil can be achieved with a lower viscosity, while semi-synthetic Buqiao oil needs to use a thicker viscosity than synthetic oil to achieve this requirement;

3. In other words, in the working environment of the same Kaimeng, the purpose of protecting the engine can be achieved with a lower viscosity of the fully synthetic oil. Similarly, in the same working environment, fully synthetic oil has a much longer service life than semi-synthetic oil, so although the cost is higher, it is not much higher than mineral oil after comparing the number of oil changes.

First, we need to give an answer. After using all the synthetic oil, we can still switch back to semi-synthetic oil. However, it has been suggested that switching back to semi-synthetic oil will lead to increased engine wear and accelerated aging.

However, it is well known that the role of motor oil is to reduce wear between parts, increase lubrication, and extend the life of the engine. Therefore, this statement is inevitably an exaggeration. In fact, switching back to semi-synthetic motor oil is not a problem, just a few things to keep in mind.

First of all, try to use the same brand and model of engine oil, because different brands or models of engine oil viscosity and quality grades are different, mixing will affect the viscosity of the oil, cause oil deterioration, accelerate engine wear, lack of ballast to reduce the service life. Of course, if you want to change the brand, be sure to clean up the residual oil and avoid mixing. In addition, we need to adjust the oil maintenance mileage appropriately.

Due to the essential difference between synthetic engine oil and semi-synthetic engine oil, after replacing synthetic engine oil, the oil maintenance mileage should be appropriately adjusted according to driving habits and actual road conditions. In general, the replacement cycle of synthetic engine oil is about 10,000 km, while the replacement cycle of semi-synthetic engine oil is about 7,000 km. However, it is possible that switching from a fully synthetic to a semi-synthetic oil is not suitable.

On the one hand, semi-synthetic motor oil is made by mixing two or three base oils in proportion with the addition of additives, which is more expensive than mineral motor oil and does not perform as well as fully synthetic motor oil. Obviously, semi-synthetic motor oil is the product of mineral oil to full synthesis. On the other hand, the biggest sail difference between the two is that the fully synthetic oil has a wider temperature range and a longer lifespan; Synthetic oil can be achieved with a lower viscosity with the same oil film requirement, while semi-synthetic oil requires a thicker viscosity than synthetic oil to meet this requirement.

In other words, in a similar working environment, the use of low-viscosity fully synthetic oils can achieve the purpose of ensuring the engine. Similarly, under similar operating conditions, fully synthetic oils have a much longer service life than semi-synthetic oils. Therefore, although the cost is high, the number of oil changes is not much higher than that of mineral oil.
