Latest Technologies in Heavy Duty Diesel Engine Oils

High performance engine oil is essential to adequately lubricate and maintain the smooth operation of an engine. But it's not quite that straightforward. High-temperature resistance, shear and oxidation stability, and aeration resistance are all requirements for engine oil. It must also be viscous enough to protect engine components while being thin enough to give optimum fuel economy. Furthermore, the oil must be cleaned on a regular basis, which means it must be filtered and changed.

Many factors relating to engine oil can have an impact on an engine's health, but frequent oil changes (also called as oil drains) are essential. The frequency with which an oil change is required has a substantial influence on a fleet's maintenance operation, therefore prolonging that interval is critical to maintaining efficiency.

Engine Oil Basics

Engine oils are classified by their viscosity, or resistance to flow; their primary base stock, which determines whether the oil is mineral, synthetic, or a blend of both; and their performance level, which determines how well the oil protects the engine, prevents wear, and protects against heat, shear, and aeration.


Most people are aware of the term viscosity when it comes to high performance engine oils. Numbers, such as 10W-30 or 15W-40, are used to indicate this. The viscosity of the oil at 0 degrees Fahrenheit is indicated by the first digit before the W, which stands for "winter." The second value represents the viscosity of the oil at 212 degrees Fahrenheit. The higher the numbers, the more viscosity there is.

Mineral Oils, Synthetics, and Synthetic Blends

The American Petroleum Institute, a natural gas and oil standards-setting body, divides engine oil into four classes (API). These levels of base oils, or base stocks, are used by lubricant firms to make specialized engine oil formulas offered to businesses and consumers, and are branded I through IV.

Performance and Technology: FA4 and CK4 Diesel Engine Oil

Engine oils can also be classified based on their performance, which refers to how well they withstand harsh circumstances. Modern diesel engines are built to be more efficient and long-lasting than past generations, which means they have tighter clearances and tolerances and run hotter. Engine oils must be resistant to oxidation, shear, and aeration now more than ever. The newest advancements in engine oil technology, FA4 and ck4 diesel engine oils, were created expressly to endure these extreme circumstances.

Although FA4 and CK4 diesel engine oil lubricants constitute a significant improvement over prior generations, fleets must ensure that the correct oils are used in each vehicle. While CK-4s are backward compatible, FA-4s should only be used if the engine's maker explicitly advises it. Storage and dispensing equipment must be correctly labelled, and technicians must be appropriately alerted and instructed when switching from older generation oils to the new requirements.

High performance engine oil technology has gone a long way, especially in the last several years. CK-4 oils have made significant advancements in terms of longevity, offering resistance to oxidation, shear, and aeration while being backward compatible with engines prior to the 2017 model year. FA-4s, on the other hand, offer the same safeguards in a more fuel-efficient packaging for today's engines and beyond.
