What is the difference between a fully synthetic motor oil and a semi synthetic motor oil?

First, base oils are different.

The base oil of a typical fully synthetic motor oil is one grade higher than that of a semi-synthetic motor oil.

The second point is that the applicable temperature is different.

Fully synthetic motor oil is suitable for a wider range of temperatures, just as in the same working environment, semi-synthetic motor oil can be used in higher conditions, while fully synthetic motor oil can achieve the purpose of protecting the engine with a lower viscosity.

Thirdly, the additives used are different.

Semi-synthetic motor oils use additives with low levels of TBN, which shortens the maintenance intervals of the oil. The additives used in fully synthetic motor oils have a high content of TBN, which can play a role in extending the life of the engine and have a certain cleaning effect.

Fourth, the replacement cycle is different.

Compared with semi-synthetic engine oil, synthetic engine oil has a longer replacement cycle, which can be changed once a year or 10,000 kilometers.

1. The grade of base oil is different.

Semi-synthetic motor oils use three types of base oils;

The base oil of the fully synthetic motor oil is made with four types of oil PAO+ additives (secret recipe).

2. The replacement cycle is different.

The oil change interval of semi-synthetic engine oil is short, and semi-synthetic is generally 8 months or 8000 kilometers, whichever comes first;

The cycle of changing the fully synthetic engine oil will also be longer, generally one year or 10,000 kilometers, whichever comes first.

3. **Different.

Semi-synthetic oils** are also less expensive than fully synthetic oils.

4. The performance of the engine oil is different.

Fully synthetic motor oils are more stable and resistant to sludge than semi-synthetic motor oils.

5. The applicable models are different.

Semi-synthetic motor oil is mostly used in economical cars; Fully synthetic motor oil is mostly used in luxury cars.

The difference between fully synthetic motor oil and semi-synthetic motor oil is:

Semi-synthetic motor oil contains certain minerals, while fully synthetic motor oil is completely mineral-free.

Semi-synthetic motor oils are more cost-effective, while fully synthetic motor oils perform better.

Comparatively speaking, fully synthetic motor oils can last longer than semi-synthetic motor oils.

Fully synthetic oils are used in a wider temperature range.

When it comes to changing the oil, the repair shop will give you two options, one is to use fully synthetic oil, and the other is to use semi-synthetic oil. So, do you know the difference between fully synthetic and semi-synthetic oil?

Fully synthetic motor oil

The manufacture of fully synthetic motor oil is made by chemically decomposing various natural substances and then synthesizing them with other substances. The advantages of fully synthetic engine oil are high cleanliness, strong fluidity, good cooling effect, excellent oxidation resistance, and long replacement cycle, which can generally reach about 1 year or 10,000 kilometers. Models with turbocharged engines are recommended to use fully synthetic motor oil.

Semi-synthetic motor oil

Semi-synthetic motor oil is made from a mixture of synthetic motor oil and mineral oil, with a ratio of 4:6 mineral oil to synthetic motor oil. Semi-synthetic motor oils are characterized by the advantages of both synthetic motor oils and their lower cost than fully synthetic motor oils.

However, the performance in all aspects is weaker than that of fully synthetic engine oil, but it has an advantage in **, and the replacement cycle is slightly shorter than that of fully synthetic engine oil, at 7000-8000 kilometers or about 8 months. Semi-synthetic motor oils are more suitable for naturally aspirated engines.
