Schaeffer's Neutra is a highly concentrated, multi-functional, ashless fuel stabilizer specially formulated for use in all grades of gasoline (including ethanol-blended gasoline), as well as all types of diesel fuel and biodiesel fuels. Blended with an enhanced detergency package, Neutra provides impressive cleanliness to fuel lines, tanks, pumps, injectors and carburetors. Neutra disperses existing deposits throughout the fuel system, safely removing them to the combustion chamber where they can be burned cleanly and completely. Additionally, Neutra can be used as a flushing fluid to purge and remove varnish and carbon deposits present in equipment.
