The NU-CALGON M4912 MotorMedic Fuel System Cleaner is a 12-fluid-ounce fuel additive formulated to clean fuel injector nozzles and restore engine performance. The formula works through the fuel system to dissolve deposits that cause hesitation, loss of power, and reduced fuel economy. It does not contain alcohol and is safe for use with catalytic converters. This product is suited for automotive and light equipment applications where fuel system maintenance is part of routine service.
The M4912 is used in gasoline-fueled engines where fuel injector deposits have caused noticeable performance issues such as rough idle, hesitation on acceleration, or decreased fuel efficiency. It is added directly to the fuel tank as a treatment dose. Service technicians and fleet maintenance professionals use this cleaner as part of scheduled fuel system maintenance or as a diagnostic first step before more invasive injector service.
Designed for use in gasoline-fueled engines as a fuel tank additive for routine injector cleaning and fuel system maintenance.
Add the contents of one bottle directly to the fuel tank before filling with gasoline. No special tools are required. Follow vehicle or equipment manufacturer guidelines for fuel additive use intervals. Avoid contact with eyes and skin, and use in a well-ventilated area per standard chemical handling practice.
