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.
