"I have a 2007 Chevy Tahoe, which is a great SUV, but has never gotten very good gas mileage. With gas prices skyrocketing, I decided to give Mileage Maxx a try because I had heard about it's ability to increase a vehicle's gas mileage. The first thing I noticed after adding Mileage Maxx was a major difference in horsepower. Now, when I hit the gas pedal, my truck responds with a jolt of acceleration. But, my favorite thing about the product is that I don't have to fill up my gas tank as often. My vehicle's gas mileage has increase by at least 5 to 6 miles per gallon. I just wish I would have found out about this product earlier. Thank you." - David (Scottsdale, AZ - USA)
