New EcoPower exceeds the highest North American standards for motor oil performance in gasoline engines. Our new eco-friendly motor oil is recycled and twice refined, using up to 85% less energy to produce than that produced from crude oil. So it’s great for your vehicle and good for the planet.
Now available at all Firestone Complete Auto Care stores in the greater Boston and Portland areas.
Properties of Recycled Oil
Re-refining motor oil reduces the need to tap limited virgin crude resources and allows environmentally conscious motorists the opportunity to “close the loop” by recycling used motor oil and purchase re-refined oil. Safety-Kleen’s modern re-refining processes turn used motor oil to a like-new condition by removing dirt and contaminants before blending sophisticated lubricating additives to protect engines.
All major car manufacturers have approved the use of American Petroleum Institute (API) certified re-refined oil in their vehicles. Safety-Kleen Motor Oil is certified by API.

Safety-Kleen is breaking new ground in the technology of recycling used oil. Our re-refinery is the largest in the world and produces every gallon of EcoPower.
Frequently Asked Questions about EcoPower
What vehicles can use EcoPower?
EcoPower can be used wherever API SM oils are specified. Most OEMs specify the use of API SM motor oils for gasoline engines. But a few models specify a synthetic oil. Check your vehicle owner's manual for the specific recommendation for your vehicle.
Which manufacturers approve using recycled motor oil?
We are not aware of any manufacturers who specifically disapprove of recycled oil. Manufacturer's approval is based on products meeting desired specifications, i.e. API SM and ILSAC GF-4. EcoPower exceeds these specifications.
Are virgin oil standards different than re-refined/recycled oil standards?
No. In fact, there is only one set of standards for lubricating base oil. Both virgin and re-refined products must meet the same standards. EcoPower exceeds these standards.
How long will recycled oil last?
Recycled oil lasts as long as regular oil. Petroleum base stocks never lose their lubricity. They become dirty from engine deposits and additives are depleted over time which causes the need for oil changes.
What is the re-refining process? Is the oil just cleaned? Is it chemically reformulated?
The process of refining used oil is the same as refining virgin crude oil. Both go through the basic processes, such as dehydration, vacuum distillation and hydro treating. At the conclusion of the re-refining process, the product is chemically altered in the same manner as a virgin product. The end product is identical and must meet the same specifications.
Which is better Castrol, Pennzoil, Mobil, Valvoline or EcoPower?
They all meet the same objective specifications: API SM and ILSAC GF-4. EcoPower takes 85% less energy to produce than products from crude oil. This manufacturing process reduces heavy metal emissions and greenhouse gases so it has less impact on the environment.
What about vegetable and tallow-based oils?
Vegetable and tallow-based oils have not met API specifications and typically cannot pass Sequence III A and G engine tests.
Can EcoPower be used in hybrid vehicles?
Most hybrids can use EcoPower. The gasoline internal combustion engine in a hybrid vehicle is the same as a regular vehicle's. EcoPower exceeds the highest North American standards for motor oil performance in gasoline engines. It can be used wherever API SM oils are specified. Follow the vehicle manufacturer's recommendations when selecting the grade of oil.
What if my vehicle requires synthetic oil? Can I use EcoPower?
EcoPower is not a synthetic. Follow the vehicle manufacturer's recommendations when selecting motor oil.
