Quick Answer
2-EHN cetane boosters contain 2-ethylhexyl nitrate as the active ingredient for improving diesel fuel ignition quality. These products typically contain 15-25% 2-EHN in a carrier solvent. They’re effective at increasing cetane numbers by 2-8 points, improving cold starts, reducing engine noise, and enhancing combustion efficiency as the most widely used cetane improver.
Expanded Answer (Simplified)
2-EHN cetane boosters are the most trusted and widely used type of cetane improver products available. These products use 2-ethylhexyl nitrate as their main active ingredient, which is the same chemical that fuel companies use when they want to improve the cetane number of diesel fuel at the refinery level.
What makes 2-EHN cetane boosters special is their proven track record. This chemical has been used safely and effectively for decades, so you can be confident that you’re using a well-tested, reliable product. The boosters typically contain 15-25% 2-EHN mixed with compatible solvents that help distribute the active ingredient evenly throughout your fuel.
When you use a 2-EHN cetane booster, you can expect to see improvements in cold starting, smoother engine operation, reduced noise, and potentially better fuel economy. The exact benefits will depend on your base fuel quality and engine type, but 2-EHN is consistently effective across a wide range of applications.
