Information about Engine Oil

Engine Oil Features
What is the difference between synthetic oil and mineral oil?
Mineral oils are produced by adding the necessary additives to the base oil obtained by processing the oil. Synthetic oils are obtained by adding the necessary additives after undergoing various chemical processes in laboratory conditions. Synthetic oils produced with a different technology in the laboratory environment are more resistant to high pressure with higher and lower temperatures than mineral oils.

Why are synthetic oils more expensive than mineral oils?
Synthetic base oil, which is the raw material of synthetic oils, is produced by undergoing intensive processes with advanced technology and its cost is high. This is the reason that affects its price.

Why do engines reduce oil?
Oil reduction is related to the technology of the engine. Metals (cylinders, pistons) are designed closer together to ensure high performance in modern engines produced with new technologies. This feature in engines causes oil to wear out and thus to decrease. Vehicle manufacturers, certain km of vehicles. They stated their oil reduction shares in their vehicle booklets. Synthetic oils decrease less than mineral oils.

Can we mix and use synthetic oils with mineral oils?
It is better not to mix synthetic oils with mineral oils. If these oils are mixed, mineral oil reduces the superior characteristics of synthetic oil.

Will fine oil damage the engine?
The point to be considered here is the use of oil suitable for the vehicle's engine and recommended by the vehicle manufacturer. If the fine oil used is synthetic, it will not damage the engine. Although synthetic oils are thin, they are much more durable than mineral oils and have high performance.

Is it useful to use other oil additives in addition to engine oil? No, it's not useful. Because all additives that the engine needs are already in a quality engine oil. The additives, which are adhered to two groups as adhering and increasing the viscosity, damage the engine in the long run by disrupting the additive balance of the engine oil. Car manufacturers do not recommend using external additives.

The disadvantages of using engine oil additive are:

Additives added to the oil may react with existing additives of engine oil and disrupt its structure. In this case, there are complaints of oil solidification.

Again, these additives block the honing lines opened for better lubrication in the cylinder walls. This makes it difficult for the oil to adhere to the cylinder walls, preventing the formation of the oil film and increasing engine wear.

What is the oil performance class? How to understand
You can understand the performance class of an oil by its API and ACEA values. These classes, which oil companies take as a result of many years of high cost studies, determine the performance of the oil.

In the oils developed to date;

SM top API performance level in gasoline class
CF and CI-4 top API performance level in diesel class
A3, ACEA performance class for passenger cars
B3, diesel, light commercial vehicles ACEA performance class for
E4 shows the ACEA performance class for heavy commercial vehicles
What does API SH / CF mean?
API; The organization that gives performance class approval is the initials of the American Petroleum Institute (American Petroleum Institute). The letter "S" indicates that it will be used in spark ignition vehicles, the letter "C" will be used in compressed ignition vehicles. These two letters are fixed and the letters behind them indicate their performance. (Such as SA, SB, SL, SM). Top class SM in petrol cars, CF and CI-4 in diesel vehicles.

CF is the top class in light commercial vehicles
CI-4 is the top class in construction machinery

Since the letter "S" is ahead in the example of API SH / CF, this oil is recommended to be used primarily in gasoline vehicles. . The letter "H" next to "S" indicates that the oil is a "H" oil in the gasoline vehicle. At the same time, this oil can easily be used as a CF class oil in a diesel vehicle.

What does 0W mean?
"W" comes from the English word winter. 0W means very thin oil with zero number oil feature in winter conditions.

Is it better than 0w-30 or 10w-60 in terms of viscosity? The suitability of the oil viscosity varies according to the place of use. For example, 0W-30 is a very thin oil. It easily circulates inside the engine and reaches every point and lubricates it. 10W-60 has a wider viscosity range and is used in very hot climates, engines with very high temperature and high performance.
