EcoPower oil put through million-mile test

Tested using drain intervals of 40K to 50K for oil changes


Safety-Kleen announced that their EcoPower Heavy-Duty Diesel 15W-40 CJ-4/SM engine oil showed remarkable wear protection of critical engine components while maintaining viscosity and acidneutralization capability over excessive 40,000-to-50,000-mile drain intervals following a million-mile test.

EcoPower is re-refined engine oil from Safety-Kleen, the largest collector and re-refiner of used oil in North America. EcoPower is re-refined using a process that consumes up to 85 percent less energy than refining engine oil from crude oil. The result is an engine oil that meets or exceeds all North American standards for engine protection, such as API and SAE, while reducing the country's dependence on foreign oil.

"This test proves definitively that EcoPower provides outstanding protection for engines while it protects the environment," said Curt Knapp, senior vice president and chief marketing officer. "Simply by using EcoPower, fleet owners and managers can now be even more assured that they can protect engines while protecting the environment by reducing greenhouse gas emissions."

In fact, for a fleet using one million gallons of engine oil per year, switching to EcoPower could reduce Greenhouse Gas emissions by 7,668 metric tons. That's the equivalent to growing 198,725 trees for 10 years in an urban environment. Additionally, EcoPower uses base oil that requires no new supply of crude oil to refine, so nearly 588 gallons of crude oil were left untouched each time either truck's oil was changed. That's because each engine requires 14 gallons of fresh oil at each oil change, and it takes 42 gallons of new crude oil to produce one gallon of high-quality motor oil – while EcoPower uses base oil that is re-refined.

EcoPower showed excellent performance over the course of a million miles in real-world conditions as two over-theroad trucks in long-haul, fully loaded service traveled one million miles each using only EcoPower for engine oil. The trucks' engines, 2007 Cummins ISX 450-horsepower EGR models, were subjected to oil-drain intervals of 40,000 to 50,000 miles, compared to the manufacturer-recommended 25,000 miles. At each drain interval, the oil was analyzed for the presence of wear metals, a sign of engine wear; acid neutralization, as reflected in a calculation known as "Total Base Number;" and viscosity maintenance, an important indicator of the oil's ability to prevent corrosion and provide engine protection.

"Even in the final oil analysis of this test, when you may expect to find the most signs of wear in an engine, EcoPower maintained a total base number of 4.9. That's well within limits and showed a substantial ability to neutralize harmful acids that build up in used engine oil and cause corrosion," said Rodney Walker, technical director of oil re-refining. "There were also completely acceptable levels of wear metals, and just like in previous tests, EcoPower was proven to
maintain its viscosity, even at the end of each oil-change cycle. Viscosity maintenance is critical to oil protecting an engine, and illustrates EcoPower's exceptional protective properties."
