Got Questions? Diesel Fuel Edition

Q. Additized diesel costs more and I’m trying to cut costs, so why should I use it?

A. It might seem counterintuitive at first but investing more in the right fuel can help save you money in the long run. Diesel fuel detergents are a clear example of this. They provide corrosion protection to metal surfaces, help prevent fuel filter plugging, and most importantly, clean up fuel injector deposits. Removing injector deposits and keeping injectors clean results in measurable improvements to engine performance such as improved fuel economy, improved engine power and responsiveness and lower emissions. This not only translates to lower fuel costs, but also reduced maintenance and downtime, all of which contribute to lowering total cost of ownership.

Q. Are all diesel fuels the same?

This might come as a surprise, but they’re not! While diesel fuels are typically produced according to regional specifications that set requirements for properties like lubricity and cetane number, the addition of fuel additives can make a big difference when it comes to performance...
