CODEX DIESEL SPECIAL,20w50- CJ-4/20L

codex Diesel engine oil with a viscosity rating of 20W50 that meets the API CJ-4 specification is a lubricant specifically designed for use in diesel engines.

Let’s break down what these specifications mean: Viscosity Rating (20W50): The “20W” in 20W50 stands for the oil’s viscosity characteristics.

In this case, “20W” means that the oil has a lower viscosity (flows more easily) at low temperatures, making it suitable for cold weather conditions.

The “50” means that the oil has a higher viscosity (thickness) at high temperatures, providing adequate protection for the engine when it’s operating at elevated temperatures.

API (American Petroleum Institute): API is an organization that establishes standards for engine oils and other petroleum products. The API classification system provides information about the performance and quality of engine oils.

The “CJ-4” designation is an API service category specifically designed for diesel engines. CJ-4: API CJ-4 represents a high-quality engine oil formulated for use in modern diesel engines, especially those equipped with exhaust after treatment systems like diesel particulate filters (DPF) and selective catalytic reduction (SCR).

CJ-4 oils are designed to meet stringent emission standards and provide superior protection against wear, deposits, and soot buildup. They offer improved oxidation resistance and are suitable for engines using low-sulfur diesel fuel.API CJ-4 oils are commonly used in on-highway diesel engines, such as those found in trucks and buses, as well as off-highway diesel engines used in construction, agriculture, and industrial applications.

It’s essential to use the correct API service category recommended by your diesel engine manufacturer to ensure optimal engine performance and longevity.

Always refer to your engine’s owner’s manual or consult the manufacturer’s guidelines to determine the appropriate oil specification for your specific diesel engine. Using the wrong oil can lead to engine damage and reduced efficiency.
