Safety-Kleen Systems announced Feb. 11 that Detroit Diesel has approved EcoPower Heavy-Duty Diesel 10W-30 CJ-4/SM for use in Detroit Diesel engines. This re-refined engine oil helps fleets improve fuel economy up to 1.5%, delivers better cold-weather starts, and protects engines and protects the environment.

The Detroit Diesel approval includes Series 50, Series 60, MBE 4000, MBE 900, and HDEP engines equipped with EGR and Diesel Particle Filters (DPF) as specified in 93K218. EcoPower Heavy-Duty Diesel 10W-30 CJ-4/SM has also been approved by or meets the requirements of Cummins, Caterpillar, Mack, Mercedes-Benz, Navistar, and Volvo.

“The approval from Detroit Diesel is further evidence that EcoPower protects engines and meets OEM requirements,” said Curt Knapp, executive vice president, Marketing and Oil Re-refining Sales for Safety-Kleen. “Fleets who switch score the trifecta—better fuel economy, engine protection and environmental protection.”

Rodney Walker, technical director for Safety-Kleen, points out the mileage, environmental, and technical advantages of using EcoPower Heavy-Duty Diesel 10W-30 CJ-4/SM.

“It can boost fuel economy by as much as 1.5% compared to using EcoPower Heavy-Duty Diesel 15W-40 CJ-4/SM. A fleet using 8 million gallons of diesel fuel at $4 per gallon could save up to $480,000. That helps lower a fleet’s costs while reducing their carbon footprint. EcoPower Heavy-Duty Diesel 10W-30 CJ-4/SM is also formulated for better cold-temperature starts and provides excellent varnish, sludge, and carbon deposit control.”

EcoPower helps protect the environment by requiring up to 85% less energy to produce than oil made from virgin crude. A fleet that uses 250,000 gallons of EcoPower per year could reduce greenhouse gas emissions by more than 1,900 metric tons per year. That’s equal to growing over 49,000 trees for 10 years in an urban environment.

Safety-Kleen’s re-refining process makes engine oil a sustainable resource. If oil is burned as a fuel source for its thermal value, its effective use is over. But when used oil is recycled into new oil products, like EcoPower, it becomes a sustainable resource that can be re-refined over and over again. And because EcoPower is recycled and re-refined from reclaimed engine oil, it also helps reduce our dependence on crude and foreign oil. It takes 42 gallons of crude oil to make the same amount of high-quality engine oil you get from recycling 1 gallon of used engine oil.

EcoPower products include:

For heavy-duty diesel:

  • 15W-40 CJ-4/SM

  • 10W-30 CJ-4/SM

  • NGP-2 15W-40 Natural Gas Engine Oil

For gasoline engines:

  • —  Synthetic Blend 5W-20, 5W-30 and 10W-30 API-SN/ILSAC GF-5

  • —  dexos1Licensed Synthetic Blend 5W-30

  • —  High Mileage 5W-20 and 5W-30 API-SN/ILSAC GF-5
