Opti-Lube Summer+ Cetane Formula Diesel Fuel Additive - 4oz 8 Pack, Treats up to 80 Gallons per 4oz bottle

Opti-Lube Summer is the Best Diesel Fuel Additive for Everyday Use.

Opti-Lube Summer+ Cetane Formula Diesel Fuel Additive is designed to enhance the performance and quality of ultra-low sulfur diesel (ULSD). This multi-functional additive helps increase lubricity, improve fuel mileage, and support overall engine performance. By providing additional lubrication within the fuel system, it helps reduce wear on critical components such as injectors and fuel pumps while supporting smoother engine operation. It also works to clean injectors, help prevent future deposits, and support a cleaner fuel system.

This formula boosts cetane by up to 5 to 7 points, supporting improved ignition quality, smoother operation, and reduced engine noise. By improving combustion characteristics and reducing ignition delay, it helps promote a more complete burn, which may support improved fuel economy and efficient engine operation. It also helps reduce deposits and emissions while providing protection against rust and corrosion. Each 8 oz bottle treats up to 160 gallons of diesel fuel and supports fuel stability while helping maintain overall fuel quality.
