Gasoline Additives
Schaeffer’s 131C SoyUltra® is a concentrated ashless gasoline additive.
Specially formulated for use in all types of gasoline and ethanol blends used in new and old two-stroke and four-stroke gasoline-powered vehicles.
SoyUltra® is made from soybean oil. It contains an additive package with friction modifying and detergency properties. This unique blend provides excellent wear protection for fuel injectors and fuel pumps – especially engines burning gasoline that’s low sulfur, reformulated, oxygenated or ethanol blend.
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.
Schaeffer’s Neutra™ provides impressive cleanliness to fuel lines, tanks, pumps, injectors, and carburetors. Schaeffer’s Neutra™ disperses existing deposits throughout the fuel system, safely removing them to the combustion chamber where they can be burned cleanly and completely.
Here are some real reviews from real customers:
"Best gas additive I have found. I have been using this in a 5.4 Ford and it runs smoother with improved fuel mileage. My lawnmower was running a bit rough so I added a few drops and within a 1/4 tank of fuel it was running smoother." Garry H.
"Great product! Use it on my generators, vehicles, stuff works great, you can really tell the difference." Raul V.
