Save fuel mileage and miles per gallon with Green Fuel Tabs. Your fuel will burn more efficiently and completely in any vehicle in both gasoline and diesel engines and therefore result in better fuel economy and MPG. Because more fuel burns, gas mileage improves and and less fuel is wasted as harmful exhaust emissions. Engine maintenance costs increase over time due to the carbon deposits that remain on the engine which result in a hotter running temperature. This wear and tear on an engine increases over time and results in both more frequent maintenance service dates, more costly replacement parts, and issues with fuel miles per gallon. Our Green Fuel Tabs require no engine modifications, no installation, and is as simple as dropping a tab into a fuel tank during a fill-up.
