Performance Under the Most Extreme Conditions.
Today’s vehicles and driving conditions demand greater performance from your motor oil. Other lubricants are also being challenged to meet more rigorous performance requirements to improve efficiencies and reduce costs.
The performance of Kleen Performance Products lubricants has been proven in both controlled research studies and real world applications. If you need peace-of-mind that your oil will stand up to the most demanding conditions, look no further than the oil that runs in NASCAR races, stands up to the rigors of military combat and outlasts the million mile journey of a heavy-duty truck.

Million Mile Engine Test Results.
2,000,000 miles of testing using nothing but Kleen Performance Products Engine Oil.
Kleen Performance Products engine oils meet or exceed all North American standards for engine protection, such as API and SAE. Our EcoPower® products provide the additional benefit of reducing the country’s dependence on foreign oil by using twice-refined oil as a renewable resource.
Two trucks. 1,000,000 miles each. Using nothing but Kleen Performance Engine Oil.
In an independent 1,000,000-mile engine test conducted on two trucks under extended drain intervals of more than 40,000 miles, EcoPower HD 15W-40 API CJ-4/SM showed exceptional engine protection – so exceptional that vital engine parts were reused when the 2007 Cummins ISX engines were rebuilt.
First, EcoPower was tested and compared for a half-million miles.
After 500,000 miles, EcoPower HD 15W-40 API CJ-4/SM was as good as or better than the two leading premium HD oils made from crude.
In fully loaded, long-haul service tests conducted by Infineum International LTD, a major global additive company, using trucks equipped with 2007 Cummins ISX 450-horsepower EGR engines, our EcoPower HD 15W-40 CJ-4/SM performed equal to or better than the two leading heavy-duty diesel engine oils. After 500,000 miles with drain intervals exceeding 40,000 miles, EcoPower delivered protection that was second to none, as illustrated in the charts below.
