Gumout Regane Complete Fuel System Cleaner, 6 oz (Pack of 6) — PEA + PIBA, CarbonClear deposit removal

Gumout Regane Complete Fuel System Cleaner is a concentrated 6 oz. treatment that removes carbon deposits, conditions fuel against ethanol and water corrosion, and restores cleaner injectors and combustion chambers in one fill-up.

Even modern gasoline can leave behind carbon, varnish and ethanol-related corrosion that reduce power and economy over time. Gumout Regane blends PEA with PIBA and a patented CarbonClear technology to attack deposits throughout the fuel system — from injectors and intake ports to piston tops and combustion chambers — while conditioning the fuel to help protect metal surfaces. This pack of six 6 oz. bottles is sized to treat multiple fill-ups, making it practical for routine maintenance every 3,000 miles.

How does Gumout Regane improve engine performance?

Regane's concentrated detergents dissolve and lift carbon and varnish that build up on injectors, valves, and combustion surfaces. Clearing those deposits helps restore spray patterns, airflow, and combustion efficiency for smoother idling and steadier throttle response.

• Contains PEA plus PIBA for enhanced deposit removal versus PEA alone
• Patented CarbonClear technology targets hard-to-reach combustion chamber deposits
• Works in direct- and port-fuel-injection systems to recover spray and flow

Will this product protect against ethanol and water-related corrosion?

Yes — the formula includes fuel-conditioning agents that reduce the corrosive effects of ethanol and moisture in gasoline. By conditioning the fuel, Regane helps slow future corrosion and the formation of new deposits that can lead to performance loss.

• Conditions fuel to help protect injectors, fuel lines, and metal surfaces
• Helps prevent future carbon build-up after cleaning cycles
• Suitable for gasoline that contains ethanol blends

Is Gumout Regane safe for my vehicle and warranty?

Regane is formulated to be oxygen-sensor safe and compatible with turbocharged and supercharged engines. It is designed to be used in gasoline engines without voiding OEM or manufacturer warranties when used as directed.

• Oxygen sensor safe formulation
• Compatible with forced-induction engines (turbo and supercharged)
• Does not void manufacturer’s warranty when instructions are followed

How do I use this 6 oz. bottle and how often should I treat my tank?

Use one full 6 oz. bottle per fill-up by adding it to a nearly empty tank, then filling the tank with up to 21 gallons of gasoline. For optimal maintenance, apply every 3,000 miles to keep injectors and combustion chambers clean and running efficiently.

• Add entire bottle to nearly empty gasoline tank, then fill with up to 21 gallons
• Do not refill until tank is nearly empty for best results
• Recommended interval: every 3,000 miles for routine upkeep

Who is this for? Gumout Regane Complete Fuel System Cleaner is aimed at drivers who want a proactive, single-fill solution to remove carbon deposits and combat ethanol-related corrosion. It's a practical choice for owners of gasoline-powered cars, trucks and SUVs — including those with turbocharged or supercharged engines — who prefer scheduled maintenance products to help preserve performance and fuel economy between service appointments. This six-pack provides multiple treatments for owners who perform regular preventative maintenance or for shops and fleets that service several vehicles.
