The Sharper Image - Official Site

Review Content Its simple and it works! Times are tough and I was looking to save where ever I could. When I saw the Fuel Efficiency Improver, I thought I would give it a try. With a money back garantee, I figured I had nothing to lose! I did a test on my 1990 Toyota Camry and i got over 12% savings in MPG. Pretty cool, so this simple plug-in device did work. Now I need to buy some new tires. Wow, This Gismo saved me about 15% MPG!! I just plugged it in and the Fuel Doctor is now saving me about 15% or about $8 bucks every time I fill up my tank. I drive an older Pontiac and i thought I would give this Fuel Doctor a try with my Gas Guzzler. So with 8 fill ups this fuel doctor paid for itself. This is the best Sharper Image product I have ever purchased! I would buy this product again and again Very good product Great A++++++ GOOD Gas Saver 1.2 gallons per mile Gas saver? I cleared my cars computer data then placed the product in my cars outlet. based on the new computer data I am getting 1.2 additional miles per gallon of gas. If you are wanting 10 plus miles per gallon, then this produce is not for you. Great Product I gave this to my boyfriend as a gift. He was excited to use it but realized that it would not improve his fuel efficiency because his car is too new of a model. We then gave it to his dad and he said it works great with his older vehicle. Dont know if it works It looks nice and doesnt get in the way but I have not noticed any significant differences while using this product.
