CI-4/E7 Diesel Engine Oil Additive Complex is a high-performance lubricant additive designed specifically for diesel engines to improve engine efficiency, reduce wear, extend engine life and provide comprehensive engine protection.
CI-4/E7 refers to a specific performance level for diesel engine oils established by the American Petroleum Institute (API). CI-4 specifications apply to heavy-duty diesel engines and provide improved control of high-temperature deposits, piston deposits, fuel consumption and wear.
The E7 specifications, on the other hand, were developed by the European Automobile Manufacturers Association (ACEA) and focus on the performance requirements of heavy-duty diesel engines commonly found in European vehicles. It includes criteria such as oxidation stability, wear protection, piston cleanliness and fuel consumption control.
When combined, the CI-4/E7 designation ensures that the engine oil additive complex meets API CI-4 and ACEA E7 performance requirements to provide a high level of protection and performance for heavy-duty diesel engines.
The ingredients of CI-4/E7 diesel engine oil additive complex include various high-performance additives, such as sulfur and phosphorus anti-wear agents, antioxidants, preservatives, friction modifiers, etc. These additives play a key role in improving engine performance and life. First of all, sulfur-phosphorus anti-wear agents can significantly reduce engine wear and improve engine durability. Antioxidants can slow down the oxidation rate of lubricating oil and keep the lubricating oil stable at high temperatures. Preservatives can prevent the production of corrosive substances in lubricating oil and protect the engine from corrosion. Friction modifiers help reduce engine friction and improve fuel efficiency.

CI-4/E7 diesel engine oil additive complex has a wide range of applications and is suitable for various types of diesel engines, including cars, trucks, engineering vehicles, etc.
There are many benefits associated with using a CI-4/E7 diesel engine oil additive package. First, it can significantly improve engine efficiency and performance and reduce fuel consumption. Secondly, it can effectively protect the engine from wear and corrosion and extend the engine life. In addition, it can also improve the engine’s starting performance and acceleration performance, and improve driving comfort.
In short, CI-4/E7 diesel engine oil additive complex is a high-quality, efficient lubricant additive that is very important for protecting diesel engines. CI-4/E7 refers to a specific performance level for diesel engine oils established by the American Petroleum Institute (API). CI-4 specifications apply to heavy-duty diesel engines and provide improved control of high-temperature deposits, piston deposits, fuel consumption and wear.
