GC101 Gasoline Injector & Fuel System Cleaner

Gas engines deal with the same problem every engine does over time — carbon buildup, fuel system deposits, and wear that slowly robs power and efficiency.

Combustion Technologies GC101 is an advanced gasoline engine treatment built to clean, protect, and improve overall engine performance. Just one bottle treats up to 20 gallons of fuel, working through the system to clean critical components including fuel injectors, fuel lines, sensors, and the fuel tank itself.

GC101 doesn’t just clean — it also boosts octane by up to 4 points, helping improve combustion and performance while reducing engine knock. At the same time, it adds important lubrication to the fuel system, helping reduce friction and wear on vital components.

This treatment also plays an important role in catalytic converter cleaning, helping remove carbon deposits that can restrict performance and fuel economy over time.

With regular use, GC101 helps:

• Clean injectors and fuel system components
• Increase octane for improved combustion
• Add lubrication to reduce friction and wear
• Support catalytic converter efficiency
• Reduce carbon buildup and harmful emissions

The result is better fuel economy, smoother performance, and a healthier engine overall.

If you want your gas engine running cleaner, stronger, and more efficiently, GC101 gets it done.
