I'm afraid this topic may have been addressed recently, if so, I apologize. But today, while they were working on my car, I took a walk down the street and passed a shop advertising Eco Power oil....no brand name, just a picture of a green quart bottle of oil. The claim was that it was 75-85% recycled or synthetic, I forget which, and they made it sound almost good enough to pour on your front lawn with no ill effects...except maybe a slippery time mowing your lawn. Heck, you might even be able to use it on a salad at dinner.
Heard of it? Used it?
