Difference Between Fully Synthetic and Synthetic Motor Oil, What is Fully Synthetic Motor Oil?

Semi-synthetic motor oil and fully synthetic motor oil are the two classifications of motor oil. The biggest difference between the two is that the 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.

Compared with semi-synthetic engine oil, fully synthetic engine oil has the following characteristics: 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.

It is mainly reflected in different viscosities, different service life, different production, etc.

The specific differences are:

1. ** Different, mineral engine oil comes from the refining of natural substances, and the general production cost is relatively low, while fully synthetic engine oil is chemically synthesized, and the production cost is relatively high, so there is naturally a big difference between the two.

2. The viscosity is different, and the mineral engine oil is greatly affected by temperature changes, and the fluidity is not good at low temperature. Fully synthetic motor oils, on the other hand, are less affected by temperature changes and can maintain good fluidity even at very low temperatures.

3. The service life is different, and in the same working environment, the service life of fully synthetic engine oil is much longer than that of mineral engine oil.

4. The production is different, the mineral engine oil is based on the mineral oil refined from petroleum, and some additives are added, while the fully synthetic engine oil is completely synthesized engine oil, which is essentially different from the mineral engine oil.

Fully synthetic engine oil, the oil only contains PAO or ester compounds, this kind of lubricant is called fully synthetic engine oil, which is the real chemical synthetic engine oil.

There are many so-called hydrofission oils (processed from mineral oil) labeled with EHVI and VHVI on the market, which are mostly labeled by engine oil manufacturers and original engine oils: synthetic technology engine oil, synthetic engine oil. This is just a synthetic motor oil with performance close to that of PAO fully synthetic oil, and it is not really a fully synthetic motor oil.

Engine oil can be divided into mineral oil and synthetic oil, and synthetic oil can be divided into semi-synthetic engine oil and fully synthetic engine oil. If you are accustomed to using minerals in 5000, you are used to semi-synthetic in 7500, and you are used to fully synthesized in 10,000.

Mineral engine oil: short mileage, frequent oil changes, cheap. Semi-synthetic engine oil, it is a mixture of mineral oil and fully synthetic engine oil in proportion, and then add additives to a mixed product, cost-effective, performance is much better than mineral oil, is a very balanced product, theoretically speaking, most models can be selected.

Compared with semi-synthetic oil, fully synthetic motor oil has the following characteristics: fully synthetic motor oil has better high and low temperature performance, longer oil change intervals, and is suitable for harsher vehicle conditions.

Whether it is fully synthetic mainly depends on the base oil. My Corolla used to use Jin Mobil 0w20 when the power within 5000 kilometers was OK, and then it was replaced by a better quality GT magic red engine oil when running at high speed, there is a one-to-one anti-counterfeiting code not worried about fakes, and it is also used 0w20 marking, but this is PAO fully synthetic engine oil power is more sufficient, and it is no problem to change it for 15000 kilometers of intense driving, and the floor oil is a low roar and there will be no noise.

Hello friends, the difference between pure synthetic motor oil and fully synthetic motor oil. 1. Suitable for different vehicle conditions, fully synthetic engine oil has very good high temperature resistance, low temperature resistance, and can also achieve a good cleaning effect, so it is very suitable for harsh driving environments. Synthetic motor oil does not provide better results for turbocharged vehicles.

2. The service life is different, and the TBN content in the fully synthetic engine oil is higher, so the service life will be longer, generally if the vehicle mileage reaches 10,000 kilometers or 1 year to replace. The service life of synthetic engine oil is short, and it is generally replaced after the vehicle has a mileage of 7,500 kilometers or 8 months. 3. Suitable for different temperatures, if the oil film is under the same conditions, the fully synthetic engine oil only uses a very low viscosity, which can bring protection to the engine, and for the synthetic engine oil, if a very thick viscosity is not used, it cannot bring better protection to the engine.

Fully synthetic motor oil refers to high-quality motor oil products that are 100% made of PAO (polya-olefin) or synthetic esters, and the word "synthetic" is marked on the oil drum.

In the classification, engine oil is mainly divided into mineral engine oil, semi-synthetic engine oil, and fully synthetic engine oil. Fully synthetic motor oil is the highest grade of motor oil, and the biggest difference between fully synthetic and semi-synthetic motor oil is that fully synthetic motor oil is used at a wider temperature and has a longer service life.

For the same oil film requirements, synthetic oil can be achieved with a lower viscosity and stuffiness, while semi-synthetic oil can be achieved with a thicker viscosity than synthetic oil.

Generated engine oil is not all fully synthetic engine oil, generated engine oil is a general term for semi-synthetic engine oil and fully synthetic engine oil. The generation of technical engine oil is classified as semi-synthetic engine oil, and we see the difference between semi-synthetic engine oil and fully synthetic engine oil below

1.The ingredients are not the same.

Fully synthetic motor oil contains 100% unconventional, high-performance fluids. This high-performance liquid in semi-synthetic motor oils, also known as "edible blends", has a smaller percentage and is infused with conventional mineral oils.

2.Performance characteristics are not the same.

In terms of overall performance, fully synthetic engine oil is better than semi-synthetic engine oil, whether it is moisturizing performance, oxidation resistance, corrosion resistance, etc., fully synthetic engine oil needs to be slightly better, that is, it has stronger high and low temperature test performance, which can be applied to more extreme vehicle conditions.

3.The teardown cycle time is not the same.

The replacement time for fully synthetic motor oil is 10,000 km or less than a year, while the replacement time for semi-synthetic motor oil is 7,000 km or 6-8 months, but the exact time depends on the specific situation.

4.Prices are not the same.

Comparatively speaking, semi-synthetic motor oil is cheaper, while fully synthetic motor oil, which is the best performance, is slightly more expensive.

If the budget is insufficient, they can choose the oil with a higher price, and if the budget is more abundant, they can take into account the three well-known brands of Castrol, Shell and Castrol, which account for the vast majority of customers in the domestic market.

Synthetic motor oil generally refers to semi-synthetic motor oil.

Semi-synthetic motor oil is a mixture of a certain amount of fully synthetic motor oil and a certain proportion of mineral motor oil. The main purpose is to reduce costs, and at the same time to obtain better lubrication effect and service cycle.

Fully Synthetic Motor Oil Synthetic motor oil is a motor oil that is synthesized and manufactured using chemical methods, and the synthetic motor oil can change various compositions depending on the purpose of use.

Fully synthetic motor oil without added mineral oil.

Fully synthetic engine oil has a longer service life than semi-synthetic engine oil, has a wider adaptability, and is more beneficial to the operation of the engine.

What is the difference between synthetic motor oil and fully synthetic motor oilWhat is the difference between synthetic motor oil and fully synthetic motor oil Synthetic motor oil and fully synthetic motor oil are not the same. There is a difference between synthetic engine oil and semi-synthetic engine oil: 1. The base oil is different, and the semi-synthetic engine oil uses the third type of base oil; Fully synthetic motor oil is made from the use of the first.

Class III, IV and V base oils are blended. Fully synthetic motor oils are one grade higher than semi-synthetic motor oils in the choice of base oils; 2. The applicable temperature is different, the use temperature of fully synthetic engine oil is wider, in the same working environment, the purpose of protecting the engine can be achieved with a lower viscosity of fully synthetic oil, while the use of semi-synthetic engine oil has relatively high requirements; 3. The conditions of the car are also different, and the semi-synthetic engine oil is more economical, small displacement, and smooth driving models; Fully synthetic motor oil can be used in a variety of harsh conditions, with good resistance to high and low temperatures. Fully synthetic motor oil is more used in turbocharged engines and high-end luxury cars.

The differences between synthetic and fully synthetic motor oils are as follows:

1. The base oil is different: the semi-synthetic engine oil uses the third type of base oil, and the fully synthetic engine oil is the first.

Class III, IV and V base oils are blended.

2. The replacement cycle is different: the semi-slip flushing and closing engine oil is replaced once every six months or 7,500 kilometers during use, and the fully synthetic engine oil is replaced once a year or 10,000 kilometers during use;

3. Different applicable temperatures: fully synthetic engine oil can be used at a wider temperature, and in the same working environment, the purpose of protecting the engine can be achieved with a lower viscosity of fully synthetic oil, while the use of semi-synthetic engine oil requires relatively high cracking;

4. The applicable vehicle conditions are also different: semi-synthetic engine oil is more economical, small displacement, and smooth driving models; Fully synthetic motor oil can be used in a variety of harsh conditions, or in pursuit of engine maintenance.

Synthetic motor oil is not all synthetic motor oil, synthetic motor oil is a collective term for semi-synthetic motor oil and fully synthetic motor oil. The synthetic technology engine oil is a semi-synthetic engine oil, let's take a look at the difference between semi-synthetic engine oil and fully synthetic engine oil:

1.The ingredients are different

Fully synthetic motor oil contains 100% unconventional, high-performance fluids. Semi-synthetic oils, also known as blended oils, contain a smaller percentage of these high-performance fluids and contain conventional mineral oils.

2.Performance characteristics are different

In terms of overall performance, fully synthetic engine oil is better than semi-synthetic engine oil, whether it is lubrication performance, oxidation resistance, corrosion resistance, etc., fully synthetic engine oil is slightly better, that is, it has better high and low temperature performance, and can adapt to harsher vehicle conditions.

3.The replacement cycle is different

The replacement cycle of fully synthetic engine oil is 10,000 km or less than 1 year, while the replacement cycle of semi-synthetic engine oil is 7,000 km or less than 6-8 months, but the specific time depends on the actual situation.

4.Different

Comparatively speaking, semi-synthetic motor oil is cheaper, while fully synthetic motor oil, which is the best performing motor oil, is slightly more expensive.

Car owners can combine the performance characteristics of the best and various engine oils to compare, if the budget is limited, you can choose the more cost-effective engine oil, and if the budget is more sufficient, you can consider Mobil, Shell, Castrol these three major brands of engine oil, these three brands occupy most of the consumers in the Chinese market.
