Gotta say I kinda thought it was a no go in the beginning. Anytime something too good to be true happens someone says, hmmm, I can make money on this deal. 20 years ago they had to pay someone to pick the stuff up. Figured as soon as they knew what was happening with it, prices and availability would go away.There are no less than five grease buyers in the area, and they are big operations. They supply the drums for restaurants to fill, and come and pick them up when full. This makes it particularly tough, since the containers the grease is put into is no longer owned by the eating establishment! Once it is in the drum, it is owned by the grease company.
They have competely pushed the WVO biodiesel operators out of business. The only way to get used fry oil is to offer a lot more money than the grease collection companies.
WMO definitely has to be chemically processed before using tho, unlike WVO which only has to be mechanically filtered & used in a converted engine.Some guys who can't get wvo use wmo waste motor/transmition oil.
Cummins allows up to 10% WMO with no changes. For a long time, they even offered a kit.WMO definitely has to be chemically processed before using tho, unlike WVO
