With all the so called milage addedrs that are claimed - if a person would use them all we would be pumping the socalled depleted oil stocks back into the ground for recycling.
If acetone were the real cat's meow with the so called (oil company self imposed shortage) don't you think that they would add this to the fuel before it is distributed. Much like ethonal blends. Which do nothing for milage (cut it back in some instances even on multiuel rated vehicles and cut power output). Hopefully the corn farmers will reap something from it.
