Castrol CRB Multi 15W-40 CF-4 Engine Oil

Castrol CRB MULTI 15W-40 CF-4 is a mineral-based engine oil specifically formulated for use in heavy-duty diesel engines. Here are the key features and characteristics of Castrol CRB MULTI 15W-40 CF-4 Engine Oil:

1. Viscosity Grade: It is a 15W-40 viscosity grade engine oil, which means it has a viscosity suitable for both cold starting (at 15W) and high-temperature operation (at 40).
2. Base Oil: The oil is formulated using high-quality mineral base oils, which provide good lubrication properties and thermal stability under a wide range of operating conditions.
3. Performance Specifications: Castrol CRB MULTI 15W-40 CF-4 meets the CF-4 specification, which is an older but still relevant standard for heavy-duty diesel engines. CF-4 oils are designed to provide enhanced engine protection, particularly against piston deposits, wear, and oxidation.
4. Engine Protection: It offers effective protection against wear, corrosion, and oxidation, helping to extend the life of engine components and maintain engine cleanliness.
5. Compatibility: This engine oil is compatible with older diesel engines requiring CF-4 or earlier specifications. It may also be suitable for certain gasoline engines where a 15W-40 viscosity grade and CF-4 performance level are recommended.
6. Applications: Castrol CRB MULTI 15W-40 CF-4 is commonly used in various heavy-duty applications, including trucks, buses, construction equipment, agricultural machinery, and other diesel-powered vehicles operating under severe conditions.
7. Maintenance Intervals: It is typically used in engines with standard service intervals and may vary depending
