Restores engine performance - thanks to a specialist deposit-removing formulation
Formulation acts on deposits that build up in injectors and fuel lines, helping to dislodge and disperse residues as fuel passes through the system. The treated fuel carries deposits away from spray nozzles and passages.
Smoother running and reduced engine noise are commonly reported by users, with more consistent power delivery during everyday driving.
Improved fuel economy - with fuel-system cleaning action
Clearing deposits helps to restore more consistent fuel flow and injector spray patterns, which supports more complete combustion. Better combustion efficiency can translate into lower fuel consumption under normal conditions.
Drivers may notice reduced fuel use and lower emissions after following the recommended dosing and routine maintenance.
