Generac - Adding Oil to Your GP Series Portable Generator

The GP series is Generac's general purpose portable line of power generators. It starts with the GP1800 which is just 18 in. X 18 in. and only 2 feet long. This little carry along is perfect for tailgating, boating, camping, running power tools or keeping your electronic batteries up and running. Even though the GP line is one of the smallest generators Generac offers, it still produces the most power on the market (up to 17500 watts).
