RoadMaster is a Cenex Premium Highway Diesel. This is a Premium Diesel fuel with an extensive additive package injected at the pipeline, not splash blended as many are in this region.
Additives in Cenex RoadMaster:
Fuel Injector Deposits
Internal diesel injector components are much smaller, lighter, and more complex than direct-injection diesel engines. If you use the typical #2 diesel fuel, deposits occur in the injector nozzle tip, Cenex RoadMaster Premium Diesel Fuel addresses these concerns and more.

In addition to forming deposits in the fuel injection system, another known issue that affects high pressure injection (HPI) systems is the premature fuel filter plugging. Fuel filters capture unwanted contaminants from the fuel and left unchecked can cause serious damage. With the extreme high temperatures and pressures generated by HPI engine technology, typical #2 diesel is thermally decomposed in the injection system and results in fuel filter packaging. As the flow of the fuel through the fuel filter becomes restricted or plugged, a loss of power will result. Black sludge, a common problem, is a critical issue in HPCR engines operating at high temperature, where contaminates from unburned fuel and combustion soot combine to further diminish performance.
Cenex Premium Diesel addresses this and many other issues that arise in new engine technology. Typical laboratory results show up to 5% better fuel economy, 10-15% add lubricity and 4.5% more power in engines that use Cenex Premium Diesels.
