You just have to excuse us over here, we aren't paying what you pay for petrol right now, and hope we never do. I have had some experience with farm machinery on LP as we call it, but only a few trucks. It seems to do fine, with some power loss, but not bad. Now, the farm boys racing their 4-wheel drive deisel turbo charged trucks will inject LP into the turbo and develop huge HP.... LP is around to stay, but just isn't used a lot in autos over here. Mostly industrial equipment.
