Valvoline provided NextGen engine oils specifically designed for lower CO2 emissions. According to Cummins, with more than 1,500 hours accumulated on the ETHOS 2.8L engine over the past 2 1/2 years, the technology has proven capable of far exceeding the 50 percent CO2 emission reductions outlined as the project goals. To complete on-road validation testing and give visibility to the project, a vehicle driving demonstration took place on public roads in California during June and July. While the powertrain system and vehicle are for testing and demonstration purposes only, market demand and production logistics are currently being explored.
