Premium Blue Extreme Diesel Engine Oil

Valvoline Premium Blue Extreme SAE 5W-40 Full Synthetic Engine Oil is designed to meet the demands of severe operating conditions and service in heavy-duty diesel and gasoline engines. Engineered for extreme temperatures, this motor oil provides outstanding performance, protection, and advanced fuel economy of up to 1.5% over 15W-40 conventional oils in on-highway operation.

The superior synthetic base stocks and additive technology of this engine oil resist oxidation, deposits, corrosion, and wear better than industry standards. It is the only oil exclusively endorsed and recommended by Cummins for both on-road and off-highway applications.

Specially formulated for faster and safer cold starts, Valvoline Premium Blue Extreme also has enhanced thermal properties to handle high temperatures during hot weather, ensuring year-round dependable performance. Additionally, extended drain intervals reduce the frequency of oil changes, allowing your engine to work longer between downtime.

This motor oil offers excellent wear protection for the critical internal moving parts of heavy-duty equipment, which can take a toll on these components. It resists oxidation and fights deposits and sludge with its higher-quality synthetic base oils and special inhibitors.

Valvoline Premium Blue Extreme is designed to protect heavy-duty equipment during cold start-ups while controlling soot, as this type of machinery can sit idle for extended periods. Its advanced fuel economy benefits can save you money on operational costs.

Cummins has recognized the exceptional quality of this engine oil, granting it a unique 5,000-mile oil drain extension in their X15/X12 engines when the average fuel economy is 7 miles per gallon or higher.

Manufactured and formulated in the United States, Valvoline Premium Blue Extreme is engineered to maximize your engine's life and improve its performance. As the only oil exclusively endorsed and recommended by Cummins, it is the trusted choice for demanding heavy-duty applications.
