Gumout High Mileage Fuel Injector Cleaner 6-Pack — Restores Throttle Response, Oxygen-Sensor Safe

Gumout High Mileage Fuel Injector Cleaner (6-pack) is a concentrated treatment formulated to remove carbon buildup from engines over 75,000 miles, restoring throttle response, fuel economy, and reducing emissions.

As vehicles accumulate miles, deposits form on injectors, intake valves and ports, which can dull performance and lower efficiency. Gumout 510013W-6PK supplies a targeted cleaning formula safe for oxygen sensors and compatible with turbocharged or supercharged engines. This six-pack gives multiple treatments for regular maintenance or for treating several vehicles, and it is designed to be easy to use with standard gasoline refilling routines.

How does this cleaner improve driving performance?

By dissolving carbon and varnish on fuel injectors and intake areas, the cleaner helps restore fuel spray patterns and air flow, which can return lost power and smoother idling. Improvements depend on deposit severity, but many drivers notice crisper acceleration after treatment. It’s a preventive and corrective product suitable for periodic maintenance.

• Removes carbon deposits from injectors, intake valves and ports
• Helps restore throttle response and smoother idle
• Reduces rough running caused by clogged injector spray patterns

Will this product work on high-mileage and forced-induction engines?

Yes — the formula is made specifically for engines with more than 75,000 miles and is safe for turbocharged and supercharged applications. It cleans areas prone to buildup in higher-mileage units without affecting turbo or supercharger operation. The cleaner is also oxygen-sensor safe and formulated not to interfere with emissions monitoring.

• Targeted for vehicles with over 75,000 miles
• Compatible with turbocharged and supercharged engines
• Safe for oxygen sensors and emissions systems

How do I use the Gumout 510013W treatment correctly?

Pour one full bottle into a nearly empty gasoline tank, then fill the tank with up to 21 gallons of fuel. For optimal results, run the vehicle normally and wait until the tank is nearly empty before the next refill; repeat every 3,000 miles as part of regular maintenance. Following directions ensures the right concentration reaches injectors and intake passages.

• Add full bottle to a nearly empty fuel tank
• Refill with up to 21 gallons of gasoline after adding
• Use at approximately 3,000-mile intervals for ongoing maintenance

Is using this product going to affect my vehicle warranty or sensors?

It is engineered for use in modern fuel and emissions systems without altering factory calibration. Still, retain purchase proof and follow manufacturer service rules for warranty matters.

• Will not void OEM/manufacturer warranty when used as directed
• Oxygen-sensor safe formulation to protect emissions components
• Designed to work within factory fuel-system tolerances

Who is this for: Drivers with vehicles that have surpassed 75,000 miles who want to recover lost performance and fuel efficiency, fleet managers scheduling regular maintenance, and owners of turbocharged or supercharged cars seeking an oxygen-sensor-safe injector cleaner. The six-pack format suits multi-vehicle households or technicians who prefer several treatments on hand for periodic preventive service.
