Purpose and Specifications

LIQUI MOLY 5105 Speed Petrol Additive is a premium fuel treatment for all 2-stroke and 4-stroke gasoline engines, including carburetor and fuel-injection types. This 1-liter bottle treats up to 400 liters of gasoline, delivering cleaner fuel systems, better throttle response, and improved acceleration.

It removes deposits from valves, carburetors, and injectors while preventing new buildup, protecting against corrosion and carburetor icing. Expect smoother engine running, higher compression, and up to 10-15% better fuel economy on regular use in everyday driving from -20°C to 40°C ambient temps. Safe for turbochargers and catalytic converters, with a shelf life of 4 years unopened.

When to Use / Replace?

Add 25 ml (one capful) for every 10 liters of fuel at each fill-up for ongoing protection, or use a full dose every 5,000 km to clean existing deposits. Ideal for daily drivers, motorcycles, or boats showing sluggish acceleration or rough idling. Replace the additive routine every tank to maintain peak performance; no fixed interval needed beyond fuel-ups.
