JBI produces Naphtha (gasoline without anything blended into it) and can be used to make high octane gasoline. So both the diesel and gasoline, once blended, could be used on the road.
However, JBI is not going to make road fuels (naphtha would be made into high octane gas by others) as there is less profit because the taxes are higher.
From what I hear, the gasoline/naptha output of the JBII processor is superior to what you get at the pump.......so I would say that's a big YES........Check out the vids of it running 4 cycle lawnmower engines....no real difference between that and a car.....z
