Introduction
Valvoline Premium Blue™ Extreme 5W-40 Synthetic Diesel Engine Oil is a high-performance lubricant designed for modern diesel engines operating under severe conditions. Endorsed by Cummins, this oil is formulated to meet API CK-4 specifications, ensuring optimal protection and performance. This article delves into the oil analysis of Valvoline's 5W-40 synthetic CK-4 oil, examining its composition, performance characteristics, and suitability for various diesel engines.
Oil Analysis Overview
A used oil analysis (UOA) conducted by Blackstone Laboratories provides insights into the oil's performance in real-world conditions. The analysis revealed that Valvoline 5W-40 synthetic CK-4 oil exhibits excellent wear protection, with zinc levels approaching 1200 ppm. This high zinc content is beneficial for protecting flat-tappet camshafts, which are prevalent in older diesel engines. The oil also demonstrated strong oxidation resistance, ensuring longevity and stability under high-temperature operations.
Performance Characteristics
Valvoline 5W-40 synthetic CK-4 oil is suitable for a wide range of diesel engines, including those equipped with Exhaust Gas Recirculation (EGR) and Diesel Particulate Filters (DPF). It is particularly beneficial for engines operating in extreme temperatures, both hot and cold, due to its excellent flow properties and oxidation stability. The oil's formulation also aids in controlling soot and maintaining cleanliness within the engine.
Comparison with Other Brands
When compared to other leading brands like Shell Rotella T6 and Mobil Delvac 1, Valvoline's 5W-40 synthetic CK-4 oil stands out due to its higher zinc and phosphorus content, providing enhanced wear protection. While other brands may offer similar performance characteristics, Valvoline's formulation is tailored to meet the specific needs of modern diesel engines, ensuring optimal performance and longevity.
Conclusion
Valvoline Premium Blue™ Extreme 5W-40 Synthetic Diesel Engine Oil is a top-tier lubricant offering exceptional protection and performance for modern diesel engines. Its high zinc content, oxidation resistance, and fuel economy benefits make it a preferred choice for operators seeking reliable and efficient engine oil solutions. Regular oil analysis is recommended to monitor oil condition and ensure continued engine protection.

Performance Characteristics
- Viscosity: The 5W-40 grade indicates the oil's flow characteristics at low and high temperatures. The "5W" denotes good cold-start performance, while "40" ensures adequate protection at high operating temperatures.
- Oxidation Resistance: The oil's formulation resists oxidation, reducing the formation of sludge and deposits, which can impair engine performance.
- Wear Protection: Enhanced anti-wear additives, including high levels of zinc and phosphorus, provide superior protection against engine wear, especially in high-stress conditions.
- Fuel Economy: The synthetic base oils contribute to improved fuel economy, offering up to 1.5% better fuel efficiency compared to conventional 15W-40 oils in on-highway operations.
