It's another decal they put on the side and it's more bull they can put in the fancy brochure or on a website.
Use hydrogen, it's lighter for less tire wear and improved fuel economy. If you have a sheet of coroplast underneath and hydrogen in your tires, when you pull into a gas station they pump fuel out of your tank and hand you money. And if your absorption fridge ***** out chances are you can patch it up and recharge it with the hydrogen in the spare tire if you happen to have a jug of ammonia based floor clear handy and some duct tape.
I've had too many Makers Marks.
On another note I see this site censors out "kraps" when speeled correctly LOL. That's ridiculous, almost as ridiculous as nitrogen in tires is.
