MADE FOR OPTIMAL LUBRICATION Your truck has been there for you every minute and every mile, which is why it’s important to keep it in pristine condition. At Opti-Lube, our goal is to keep your engine operating at its best. Our fuel additive helps to increase the lubricity properties of ultra-low-sulfur diesel (ULSD) so that you can play more and worry less.

IMPROVES FUEL ECONOMY Trucks are known for eating up fuel. Fortunately, there’s a way to fix that with Opti-Lube Summer+ Cetane formula. This diesel fuel additive has been shown to enhance fuel mileage year round, giving you more bang for your buck. With greater fuel economy, you’ll find increased power for summer driving.

CLEANS INJECTORS When your fuel injectors build up with residue, your engine doesn’t run as efficiently. Opti-Lube Summer+ Cetane formula cleans injectors while helping prevent future build-up. This helps to reduce deposits and emissions, making this lube compatible with all vehicle emissions systems. Additionally, it acts as rust and corrosion prevention to keep your vehicle in tip-top shape.

ENHANCES PERFORMANCE Whether during rain or shine, Opti-Lube Summer+ Cetane formula delivers. It works to improve the performance of your truck all year round. This fuel additive also helps separate water from diesel fuel as a demulsifier and more than doubles the storage life of standard diesel fuel.

MADE ESPECIALLY FOR SUMMER Summertime is hard on your fuel. The higher temperatures can cause faster thermal degradation of the fuel. Fuel prices tend to spike during the summer too, so you’re typically spending more when you’re at the pump. Our Summer+ Cetane is the best diesel fuel additive for warm weather and your wallet. It helps improve fuel mileage and helps prevent fuel breakdown.
