I might be posting this on the wrong forum, but since in involves mowing, I guess it's OK. I work a few hrs. during the week for another lco, and the other day I discovered that they are using off road diesel in their trucks...the same trucks that are on the city streets and highways all week! I mentioned something about it to one of the owners, but he didn't seem too concerned. Has anyone ever been caught with off-road fuel in their mowing/work pick-up?? What's the fine$$$$$ ?
