Being able to run both gas and diesel sounds good but, unfortunately, it often doesn't materialize too well. Just look at GM's 350 experiment. That's not saying it can't be done. I'm just saying it needs to be done properly and it often isn't. I think that's particularly true when a gasoline (spark-ignited) engine has been "adapted" to diesel. From what I've seen the diesels that have been adapted to spark-ignited fare much better. I know Cummins as well as Caterpillar at others have spark-ignited natural gas verisons of many of thier diesel engines that do quite well.
