YEFE Endurox HD Xxtra 15W-40 is engineered for use in heavy-duty diesel engines where API CI-4 performance is required, including engines with EGR and/or SCR emission control systems. It is particularly suitable for fleets operating in regions with low to moderate fuel sulphur levels and needing a versatile all-season 15W-40 oil.
Key technical features include:
- API CI-4 performance level, supporting use in Euro 3, Euro 4 and Euro 5 diesel engines equipped with EGR and/or SCR systems (excluding applications that require low-SAPS oils for DPF-equipped engines).
- High dispersancy and detergency properties help control soot, deposits and sludge, keeping pistons and internal components clean for consistent engine performance.
- Good anti-wear, anti-foam and anti-corrosion properties help extend component life, maintain stable lubrication films and protect against rust in harsh operating environments.
- Excellent thermal and oxidation stability helps maintain viscosity, slows oil thickening at high temperatures and supports longer oil drain intervals when aligned with OEM recommendations.
- Multigrade SAE 15W-40 viscosity ensures good cold-start performance while providing a strong lubricating film at normal operating temperature, suitable for a wide range of climates and duty cycles.
The oil is also suitable for certain stationary engines and industrial applications where API CI-4 15W-40 performance is specified and fuel sulphur levels are within the recommended range.
