CENEX® RUBY FIELDMASTER®PROVEN IN THE LAB AND IN THE FIELD Today’s diesel engines use high-pressure, common-rail (HPCR) direct-injection technology for significantly greater efficiency than conventional diesel engines. The high temperature and pressure these engines operate at can literally cook typical #2 diesel, resulting in fouled fuel that can damage engine parts. Ruby Fieldmaster has been enhanced to provide optimal performance for high-tech engines, including those that will need to meet the upcoming Tier IV Final EPA emission standards. In more than 14,000 hours of grueling real-world tests, Ruby Fieldmaster prevented injector fouling and filter plugging while delivering premium power and fuel economy.
