And you can use it in your deep fryer: http://www.hort.purdue.edu/newcrop/ncnu02/v5-029.html "Oil changes from petroleum to bio-based oils also show very significant reductions in tailpipe exhaust emissions (Fig. 6). In a petroleum to petroleum cycle (Pet-pet), hydrocarbons (HC), carbon monoxide (CO), and nitrous oxides (NOx) all show increases over the 6,500 km test period. Conversion from petroleum to a bio-based motor oil (pet-can) has an immediate and dramatic decrease in exhaust emissions. Continued use of the bio-oil continued to decrease HC production while giving no additional losses to the already depressed CO and NOx production."
