Generally cars and boats pollute more while being produced than they do in their entire lifespan of use.
I am sorry if i offended someone with my language here, but I feel we really are destroying the earth by pumping all this oil out. I will not make a political thing out of it, as i got feedback that it was kind of trolling the thread.
My point was merely that I hope that if more people uses bio fuels, it will help the environment, even if it is only a 5% blend.
My point is that it is possible to drive on B-100, but you must be willing to do some actual work to get it done. I have proved it on an "impossible" engine on a car, and in time I will do it with my boat.
But sure, it is easier to just fill regular fossil fuel.
