In order to answer this question, let us compare them with synthetic oils. But to better understand the differences between fully synthetic and semi-synthetic, we first need to take a look at how completely synthetic differs from traditional mineral oil.
Fully synthetic and mineral oil
The names of the two oils tell most of the story. The former is a more natural form of oil, while the other is artificial. Just like diesel fuel, mineral oil is obtained from crude oil refining.
Synthetic motor oils, on the other hand, are made through the processing and refining of chemicals. They can be designed to better cope with phenomena such as high temperature and oil failure. Simply put, fully synthetic oils will perform better and last longer than petroleum products.
What is semi-synthetic oil
The purchase price for a fully synthetic oil (compared to conventional mineral oil) can be quite high. For this reason, a semi-synthetic base intermediate (also known as a synthetic blend) has been found. Semi-synthetic materials are made by mixing traditional mineral oil with synthetic oil. They are intermediate between mineral and fully synthetic oils in terms of performance, price, quality and durability.
Fully or semi-synthetic oil
Price
If you have enough cash and the price you pay for a fully synthetic oil suits you, then synthetics are for you, and you will provide your engine with better protection with the added benefit of extending the time between replacements.
Engine tuning
If the engine is set for maximum power, it is recommended to select a fully synthetic material, as the internal structure of the engine will be heavily stressed. But, if the car is not designed for "street racing", then completely synthetic oil is not necessary. Because many engine manufacturers take into account the fact that people will use different types of oils.
Friction force
There is a long-standing idea that there is a risk of slippage in synthetic oils. In fact, synthetic oils are no more slippery than mineral oils. However, due to differences in clutch designs, friction modifiers are added to some oils to prevent it from causing slipping.
From all of the above, we can conclude:. Also, semisynthetics show better qualities than mineral oils, and are an excellent solution for the average person with a car.
