O K Before you know it, there is going to be a flood of “miracle” gas use improvement scams, and I mean some will be so ridiculous that they will seem believable.
DON'T!
One thing that does work is to EDUCATE yourself on how to operate and maintain YOUR vehicle!
It is impossible to get more fuel mileage from a quantity of fuel by “rearranging its molecular structure” If this were possible all of us would control our own destiny in world politics and power. And by the way magnets don't work either.
You can add more air to the gas but then you shorten the life of the engine, you can add water (which by the way most refineries already do) or you can change certain gear ratios in the propulsion gears and shafts.
Basically what you have here is a “failure to communicate”. I want to change that, I want you to know what to do for your gas or diesel burning rig; I bet you have something to add as well.
