What if you could actually improve your gas mileage significantly (5-20%)? Not have to alter your driving habits? Not have to install any extra questionable parts on your car? What if it were as easy to do as 1-2-3?
Well, it is.
For years Big Oil has offered three or so different grades of gas octane 87 regular, 89-90 premium and 91-94 super.These grades are actually based upon a 100 octane scale where the cleanest burning, most ideal fuel was propane (clean burn fuel)....
Processing. Please wait...
