I ran a 20% mix of homemade yellow grease biodiesel summer '03 in all three trucks for a total of about 50 gallons biofuel in all. I wanted to experience the smell of it and see how it affected my engine. The impression that I got was that it made the engine run like a well oiled machine, it cleaned the fuel system(as shown by how much crud the fuel filter keep accumulating) and the smell is awesome, but it makes you think of what ever greese it is(I used greese from a chineese restaurant). Weather this is pleasant or not is up to you. It made me hungry.
