CF-4/SG General Purpose Engine Oil Additive Complex is a lubricant additive blend specifically formulated for gasoline and diesel engines requiring API CF-4 or SG performance levels.
It is formulated to provide enhanced protection against wear, corrosion, deposits, oxidation and blistering. The kit is suitable for a wide range of gasoline and diesel engines used in heavy-duty trucks, buses, commercial vehicles and off-highway equipment.
CF-4/SG General Purpose Engine Oil Additive contains detergent and dispersant additives that prevent the formation of deposits and sludge to help keep your engine clean. These additives also help disperse and suspend contaminants, preventing them from causing engine damage.
Additionally, this additive package contains antioxidants that help prevent oil oxidation and the formation of harmful acids that can cause engine wear and corrosion.

In addition, the CF-4/SG General Purpose Engine Oil Additive Pack contains anti-wear agents to prevent friction and wear. These additives form a protective film on engine surfaces, reducing wear and extending the life of critical engine components.
Additionally, CF-4/SG General Purpose Engine Oil Additive contains viscosity modifiers that help maintain oil viscosity and ensure proper lubrication under varying temperatures and operating conditions. This is especially important for engines exposed to a wide range of temperatures and loads.
The engine oil formulated with general-purpose engine oil additives has excellent soot dispersion, high-temperature cleanliness, and good antioxidant, wear-resistant, and corrosion-resistant properties. Different dosages are added to the appropriate base oil to meet the requirements of multi-grade oils. Performance requirements.
In summary, the CF-4/SG General Purpose Engine Oil Additive Package is a comprehensive additive blend that provides superior engine protection and performance. It meets the requirements of API CF-4 and SG performance classes, making it suitable for gasoline and diesel engines.
A CF-4/SG universal type engine oil additive package is a blend of additives designed to enhance the performance of base oil for a wide range of engines, typically catering to older gasoline and diesel engines. Here’s a breakdown of the API classifications (CF-4/SG) and the role of these additives:
API Service Categories (CF-4/SG):
The American Petroleum Institute (API) classifies engine oils based on their performance characteristics. In this case, the package combines two categories:
- CF-4: This signifies an oil suitable for older high-speed diesel engines built before 1994. It offers protection against soot, wear, and oxidation under these operating conditions.
- SG: This category specifies an oil for gasoline engines introduced before 2000. It provides protection against wear and tear under moderate operating conditions.
Universal Design:
By combining CF-4 and SG functionalities, this additive package aims to address the lubrication needs of both older gasoline and diesel engines in a single product. This can be beneficial for:
- Mixed fleets: Servicing a variety of older vehicles with both gasoline and diesel engines.
- Cost-effectiveness: Simplifying inventory management by using one additive package for multiple engine types.
Typical Additive Functions:
The CF-4/SG universal package likely includes many of the following additives commonly found in engine oil additive packages:
- Anti-Wear Additives: These additives, like ZDDP, minimize friction and wear on engine components.
- Detergents and Dispersants: Detergents remove contaminants like sludge and soot, while dispersants keep them suspended in the oil, preventing sludge build-up.
- Antioxidants: These help prevent the oil from thickening and breaking down due to high operating temperatures.
- Corrosion Inhibitors: These additives form a protective layer on metal surfaces to prevent rust and corrosion.
