I mixed some of my biodiesel with the gas in my garden tiller yesterday just to see what would happen. It was about a 75/25 mixture and it ran good. I was just wanting to know if anyone else has mixed it before or any other info on this idea.
There has been a lot of talk about this on another bio forum I belong to. The consensus seems to be that more than 15 percent will cause "coking" behind the rings, causing the bore to wear much faster. If you stay below 10-15 percent you should be able to use it. Most of the people I've talked with say they get some improvement in milage, probably because Biodiesel is an oxygenated fuel.
