Opti-Lube Summer Lube +Cetane Diesel Fuel Additive in a 5-gallon pail is designed to enhance the performance of your diesel engine during warm weather. This premium fuel additive excels in providing outstanding lubrication to the fuel system, which protects your equipment and contributes to overall operational efficiency. Summer+ Cetane is more than just a lubricity enhancer; it also cleans injectors, boosts cetane levels by 5 to 7 points, and ultimately improves fuel efficiency.

Higher cetane levels in diesel fuel lead to better cold starts and reduced engine noise. With an increased cetane number, you experience a shorter ignition delay, which allows for a more complete burn of the fuel. This often results in improved miles per gallon and better engine performance. Diesel engines work most efficiently with a cetane number ranging from 40 to 55. By using Opti-Lube Summer Lube +Cetane, you ensure that your diesel engine operates at its best, maximizing both performance and cost savings at the pump.
