It doesnt smell like the actual meat frying, just hot veggie oil I guess. I live in the middle of Kansas, soybeans planted for miles, maybe its why its cheaper?. The guy had a few square plastic containers with a metal frame that were filled with what said on the side "WVO", and he said he processes it with lye and methanol? and then washes it and dries it amongst other processes? Anyways, I will check my timing this weekend. But I have not noticed a loss in power, maybe even a slight gain. But yeah, at those prices, I plan to run it all summer and fall. Then go to D2 or B20 in winter. As I was filling up, 3 local farmers pulled up in huge tractors, the bio diesel guy said " well I got my work cut out for me, see you again soon"
