Product Information

Blud Lubricants Heavy Duty CK-4 extended service engine oils are the ultimate in diesel engine oil.

These oils are not something you will find on the shelf of a discount retailer. If you are a person looking for a product that will outperform traditional mineral and synthetic oils are a perfect fit for you. We build our products to perform at higher standards rather than just clearing the minimum requirements set by OEM specifications. Choices are important when selecting raw materials for finished products. Good choices in formulation allow these oils to excel in extended drains in tough operating conditions. Premium additives coupled with base oils that have low volatility mean these oils can minimize consumption, reduce wear, provide a lower coefficient of friction, have much greater oxidation stability, and will run very clean in service.

It also uses an advanced VI improver that has a shear stability index of only 5. It is designed for equipment, environment, or service that is particularly harsh.
