I agree it is nice to have a recyclable resource, but are we actually recycling it? According to Earth 911, we are burning a "large portion" of used oil. I haven't found anything yet on what that number actually is, but that's not really recycling.
EDIT: According to Scientfic American, only 10% of used oil is recycled. The rest or majority of the rest is burned for power generation. 10% of 1.3
BILLION (with a 'B') gallons.
To me recycling is re-refining it to use again and again in a motor (or similar).
Also, isn't burning oil more pollutive than gas or diesel? Or is that only if the engine isn't designed to burn oil?
I still think "growing" our lube oil (and electricity oil) is better than using crude.
Thanks kir_kenix, I'll have to look into "alternative" oils. This seems to be on par with "orange" tires that is a popular thread right now. I wonder if I can get my car to smell like an orange tree or tropical oasis with these alternative products!
I think I found the Valvoline recycled stuff kir_kenix was talking about.
