B3C Fuel Solutions Mechanic In A Bottle Gas Treatment is specially designed to restore old fuel by breaking apart the hydrocarbon chains that have bonded together as the fuel deteriorates. This treatment includes an octane booster that replenishes the lost octane in decayed fuel, helping to improve engine performance. It effectively removes carbon deposits from critical combustion chamber components such as the chamber itself, pistons, rings, and valves. The formula contains dual lubricants that condition rubber and plastic parts, rejuvenating rubber gaskets and seals that may have dried out due to ethanol exposure. After combustion, a synthetic lubricant remains to protect the entire upper combustion chamber, including piston rings and valves. This product is a fuel additive and should not be used as a for 2-cycle oil; continue to add oil as by the engine manufacturer. Mechanic In A Bottle is registered with the EPA and is by B3C Fuel Solutions for use with nonroad gasoline engines. Model Number: 2-004-12
