ATS Chemical 505 CRF Fuel System Treatment 16 oz — Carbon & Injector Cleaner, Restores Power & MPG

ATS Chemical 505 CRF is a concentrated 16 oz fuel system treatment designed to remove carbon deposits and clean injectors in both gasoline and diesel engines.

Over time fuel injectors, intake ports, and valves collect varnish and carbon that reduce engine efficiency and throttle response. The 505 CRF formula targets those deposits to help restore smoother running, improve fuel economy potential, and lower emissions-related buildup. It’s sold in an easy-pour 16 oz bottle and is formulated to treat a broad range of fuel volumes, making it suitable for routine maintenance or targeted cleanups.

How does 505 CRF clean injectors and intake ports?

The formula contains detergents and solvents engineered to dissolve varnish and carbon that cling to port and direct injectors as well as induction valve surfaces. When added to the fuel, it circulates through the system during normal operation, lifting deposits so they can be burned off or flushed out.

• Breaks down carbon and varnish on injector tips and intake ports
• Compatible with port-style and direct injection systems
• Works in both gasoline and diesel fuel applications

What fuel volume does one 16 oz bottle treat and how often should I use it?

One bottle treats between 5 and 20 gallons of fuel, covering the fuel loads of most passenger cars, light trucks, and small commercial vehicles. Frequency depends on driving conditions and fuel quality; use it as part of scheduled maintenance or when you notice reduced performance or rough idling.

• Treats 5–20 gallons per 16 oz bottle for flexible dosing
• Use during fill-up for best circulation through the system
• Recommended for periodic preventive maintenance or targeted cleaning

Will 505 CRF affect my fuel type or emissions system?

505 CRF is formulated for use in both gasoline and diesel engines and is compatible with modern fuel system components when used as directed. It is intended to help remove deposit buildup; it does not alter fuel octane rating or require engine modifications.

• Safe for gasoline and diesel when used per instructions
• Non-destructive to fuel system seals and sensors when dosed correctly
• Helps reduce deposit-related emissions by clearing combustion pathways

How do I pour and use the ATS Chemical 505 CRF bottle?

The bottle is sized and shaped for easy pouring into a vehicle’s fuel tank or fuel-fill funnel. Add the recommended amount based on your tank volume, then drive normally so the product circulates and cleans while the engine runs.

• Measure dosing according to tank size and product directions
• Pour at fill-up for immediate mixing with fresh fuel
• Drive normally; cleaning occurs during regular operation

Who is this for: ATS Chemical 505 CRF is for drivers, fleet managers, and DIY mechanics who want a practical maintenance product to address fuel-system deposits in gasoline and diesel engines. It suits owners of older vehicles with deposit buildup as well as newer cars seeking preventive maintenance. If you need a concentrated, easy-to-use cleaner to help restore throttle response and fuel efficiency potential without off-vehicle service, this product is appropriate.
