GT5 is effective by using a multi-pronged approach including surfactant, detergent, top oil, octane enhancer and combustion modifier. Surfactant controls water by breaking down its surface tension in fuel systems to reduce corrosion. Detergent helps clean fuel systems, cylinders, injectors, spark plugs and exhaust to remove tar, varnish, gum and carbon. Top oil lubricates valves, upper cylinder area and moving parts in the fuel system which can restore lost compression. Octane enhancer enhances burn regardless of fuel octane rating to reduce pinging and detonation. Finally, combustion modifier smoothes the combustion process to reduce emissions, reduce fuel consumption and increase power.
