I put this in the lounge b/c its not truck related. Anyway, my wife decides to mow the back yard this past weekend. I get home and she tells me she used the last of the gas. Well I knew we didn't have any gas but we had a little diesel that I had used to start a brush fire a few weeks ago. The thing is, she says it ran fine. I asked her if it smoked or anything and she said it ran just like it always does. I was surprised it ran at all, and if it did it seems like it would smoke alot. I have never run diesel in a gas motor before so I'm guessing but thats what it seems like. Hey, at least she cuts the grass.
