Schaeffer's Neutra Fuel Stabilizer

Schaeffer's Neutra Fuel Stabilizer 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 Fuel Stabilizer 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, Schaeffer's Neutra Fuel Stabilizer can be used as a flushing fluid to purge and remove varnish and carbon deposits present in equipment. Neutra Fuel Stabilizer is suitable and meets the US EPA requirements for blending into low sulfur diesel fuels (for use in diesel vehicles 2006 and older). When used at the recommended treatment ratios, Schaeffer's Neutra Fuel Stabilizer will not cause a measurable increase in the sulfur content of the diesel fuel and will not have any measurable effect on cetane index or aromatic content of the diesel fuel. Features and key benefits of Schaeffer's Neutra Fuel Stabilizer include: * Optimizes performance and fuel economy up to 5 percent * Lowers the freeze point of any water that may be present in the fuel * Stabilizes fuel during storage * Reduces emissions, exhaust smoke and particulates * Keeps injectors free from varnish, deposits and gum * Lubrication of upper cylinders, fuel pumps, injectors and carburetors—also offers supplemental ring and valve-train anti-wear protection, and excellent anti-wear protection of the injectors and fuel pumps * Excellent moisture control and the prevention of corrosion associated with moisture * Inhibition of breakdown and oxidation of regular and ethanol blended gasoline during long-term storage

Maxima Hi-Test Octane Booster

Maxima Hi-Test octane booster is a concentrated octane booster legal for all types of competition. Hi-Test octane booster is an all organic product containing no metal compounds. Hi-Test readily mixes with all gasoline's as well as alcohol and nitro mixtures. Hi-Test will suppress detonation and pre-ignition by modifying the burn rate and increasing the auto-ignition temperature of the air/fuel mixture. The use of Hi-Test octane booster in your gasoline will eliminate "pinging" and "knocking" and the potentially destructive results of them. Hi-Test will allow for higher compression ratios and therefore more horsepower. One ounce per gallon raises the effective octane number approximately four points, depending on the base gasoline octane. For racing or very high compression engines, or very low quality fuel, higher concentrations of Hi-Test may be required.
