Why fuel system cleaning matters

Over time, combustion deposits, water contamination, and ethanol byproducts can build up across your fuel injectors, intake valves, and combustion chambers. These issues don’t just reduce power - they can increase emissions, lower fuel economy, and cause long-term damage.

One Shot: High-impact performance in one dose

Unlike multi-step treatments or DIY cleanouts, One Shot delivers comprehensive results with zero guesswork. Here’s what it targets:

• Carbon buildup - Formulated to dissolve and flush combustion deposits that affect power and throttle response.
• Water contamination - Absorbs and disperses moisture in the fuel system to prevent rust and phase separation.
• Injector and valve deposits - Cleans injectors and valves for smoother combustion, better idle, and lower emissions.

Proven results, backed by data

One Shot isn’t just a quick fix - it’s a high-performing cleaner with real test data to support its claims. In independent assessments, One Shot has shown improvements in fuel economy, combustion efficiency, and emissions reduction.
