Q&A with MKC Energy

May 18, 2023

Q: What’s the difference between standard #2 diesel and premium fuel? A: A premium diesel has a higher cetane number, better lubricity and includes detergents that provide injector-cleaning capability versus standard #2 diesel. Cetane measures a fuel’s ignition delay. Higher cetane equals a shorter delay and better ignition quality for quicker start-ups and less pollution. Lubricity improver is used to reduce the friction and wear of fuel pump and injector components under pressure, which extends the life of the fuel pump and reduces downtime. Detergents keep fuel injectors clean for optimal engine performance. In more than 14,000 hours of grueling real-world tests, CENEX ROASMASTER XL® prevented injector fouling and filter plugging while delivering premium power and fuel economy. Tests have also shown a 4.5% increase in power compared to standard #2. Q: Are all premium fuels alike? A: No, both base fuels and additives used to achieve “premium” status can vary widely by a supplier. Ruby Fieldmaster® offers a quality base, soy-enhanced fuel and a complete, multi-functional additive package formulated for the rugged demands of agriculture. It’s continually researched and tested to ensure the highest quality premium diesel fuel on the market. That’s why we can confidently offer our unequaled Total Protection Plan® diesel fuel warranty. Q: I’ve been using plain #2 diesel for years without a problem. Why switch now? A: Over time, your engine’s fuel pump and injectors get dirty – a gradual, hard-to-notice process that reduces both engine performance and a fuel economy. Plain #2 fuel contains no additives to reduce wear, extend storage life or reduce the formation of gum, varnish, and corrosion.

Q: Why not just buy an over-the-counter additive for my #2 fuel? A: Many over-the-counter additives have solvents that offer insufficient benefits. Plus, they usually cost you more than premium fuel.
