Opti-Lube is the ultimate in performance diesel fuel additives, dedicated to protecting your equipment by providing exceptional lubrication in the fuel system (ranked first in an independent study). Summer+ Cetane is the best diesel fuel additive for warm weather and your wallet.

Improving Lubricity is just the beginning, this product also improves efficiency, cleans injectors and boosts cetane by 5 - 7 points.

“Why do I want higher cetane in my diesel fuel?”, you ask – By increasing the cetane number of your fuel you improve cold starts and reduce engine noise. By reducing the ignition delay cetane causes a more complete burn, this commonly results in increased MPG. Generally, diesel engines operate well with a CN from 40 to 55. As mentioned earlier, fuels with a higher cetane number have shorter ignition delays, providing more time for the fuel combustion process to be completed. Hence, higher speed diesel engines operate more effectively with higher CN fuels.
