Default Re: Real life gas mileage?

Instead of just air they fill your tires with nitrogen. It's suppose to help your gas mileage, prolong tire life and give a smoother ride. I can't tell you if it actually works since I bought my H2 with it already done from the dealer. I did get 15.5 mpg on the highway @ 65 mph. I can post a link later or just google Nitrofill for more info.
