Diesel engines continue to see significant advancements with the global push towards lower emissions and greater fuel efficiency. One such example is the growing use of high pressure common rail diesel injection systems. But as diesel equipment becomes more complex, it is vitally important that diesel fuel also evolves. A higher quality diesel fuel enables newer equipment to operate as intended. The Lubrizol Diesel Additives channel on YouTube is intended to help educate fleet managers, end users/operators, influencers, and fuel marketers on the importance of high quality, differentiated diesel fuel for today's engines. The role of tested and proven additives is essential to unlocking new performance benefits in diesel fuel.
