I am, I've got about 3k running it, have to wait a bit to tell you truthfully there are no probems. I don't have a systen and that's not the safest way to run it but I do mix it with diesel, whatever is in the tank add some oil to it as it's running and go to the gas station to add some diesel on top too. The most important thing is to filter it vey well. I wasn't filtering it that well at first and it smoked more at start up, now it doesn't inless I get impatient and try to start it without waiting to long for the glow plugs to get hot. Now I always wait for the relay to click and it's filtered way better.
