We will often see on the packaging that every car oil bottle has an API circular symbol. API is the abbreviation of American Petroleum Institute - American Petrochemical Institute, this is the most basic decentralization to evaluate the quality of lubricants of gasoline and diesel engines. So is diesel engine using CK or CJ oil for the best? And Thanh Phong Auto Read through the article below.

API classifies lubricants by using 2 characters:

+ Grade S is used to use for gasoline engines.

+ Grade C is used for diesel engines.

+ The second letter after S and C indicates a gradual increase in quality in alphabetical order. The later the product quality the better. For example: SN will be higher than SM, SM will be higher than SL

+ Similar to diesel engine oils starting from CA, CB and the latest CF-4, CI-4.

Thanks to the API evaluation, we can know what kind of oil production technology is still suitable for use and which type is not suitable for your vehicle engine.

Properties of lubricants for gasoline engines

Lubrication is the basic nature of lubricants, lubricants used for gasoline engines are often more advanced in terms of lubrication. The reason gasoline engines have higher engine revs is because the engine parts are usually lighter and more compact than other engines.

However, it is also possible that in some cases the gas engine has a rpm up to 7000-8000 rpm. Once the rpm of the machine has been increased, then the oil must be loose. At the same time, the viscosity must also ensure to promptly circulate inside the engine, easy access to the parts to create a lubricating film to cover and protect them from direct friction against each other.

It is not difficult to do this, just using the best oil for the engine is the total oil - a type of oil whose molecules are very high, very small. so it can easily and promptly slip into the machine's parts to lubricate.

Properties of lubricants for conventional diesel engines

Under normal operating conditions, the rpm of a diesel engine in general such as passenger car, truck, bus or heavy engine in an industrial park, .. is usually in the range of 1000-2000 rpm, a lot lower than a gasoline engine.

Compared to gasoline engines, diesel engines produce more carbon deposits and are dirtier. Therefore, diesel engine oils are used to disperse, wash and neutralize acids generated during diesel operation. The higher API Cx grade lubricant is, the more lubricant it contains.

According to current API, lubricant technology levels suitable for new diesel engine systems are only from CH-4, CI-4, CJ-4 and CK-4. As for standards such as CF, CF-4, CG-4, it is only suitable for engines manufactured before 2009. From CG backwards, it was no longer used for engines manufactured after 2009.

Particularly for lubricants for gasoline engines with API grade of SN, it only reaches the grade of diesel engine is CF only, but the highest API level for diesel engines is CK lubricant. When there are many additives in the oil, it will work with each other and lose the function of the lubricant, this time, the lubrication and rotation of its engine will be greatly reduced. As a result, the lubrication requirement that the engine requires it will not meet the demand, thus making it impossible to reach SN grade anymore.

However, with new improvements in engines and increasing diesel quality, the vehicle uses diesel highly efficient. Plus an inherent advantage of diesel cars is that the cost of raw materials is much cheaper than gasoline. More than that, today's diesel engines have taken on newer strides. It is not uncommon for today's diesel engines to go up to 4000 - 5000 rpm because the engine has high pressure oil injection and turbocharger.

On the other hand, once the turbocharged diesel engine operates, it will create a greater power than the engine, making high revs also require the use of lubricating oil capable of lubricating at the rpm. high. Therefore, there is no need for any lubricant with too much detergent or other additives, but just use a high lubricating oil to contribute to increased engine efficiency and fuel economy. the most optimal way.

Therefore, when pouring synthetic API SN / CF oil for diesel engines, it will make the car feel quieter, save more fuel, more comfortable because it has a hundred times better performance for oil. specializes in regular cleaning.
