Review on 🚀 Miracle3 Fuel Saver Mileage Booster - Universal Gas Saver for Cars and Trucks - Enhances Combustion Chamber for Improved Fuel Efficiency, Reduced Vibration, and Lower Exhaust Emissions - EURO 6 Gasoline by Hunter Feerey

If you don't have basic mechanical skills you'll need someone to install this for you, but it's actually quite easy and there are some good videos on the web that explain step by step how to do it. My husband does all the mechanical work on our cars and it didn't take long for him to assemble and install it on his car. In terms of increased fuel economy, we haven't seen a HUGE difference, but I'd say we're definitely adding at least another 4 or 5 miles to the tank, which is great. You'll notice a slightly bigger difference on the highway. We drove to OKC recently after installing it and I could tell we haven't had to fill up that often so it certainly works to a degree, but don't expect it to cut your mileage in half and will ensure you keep up . all your other basic maintenance tasks. Overall I'd say it's good value for money and definitely worth it in the long run. This will surely save you so much money in the first year that it will pay off, and then you will save real money in the long run.
