Royal Purple Max Clean Fuel System Cleaner 20 oz Bottles — 6-Pack Concentrated Injector & Deposit Remover

Royal Purple 11722 Max Clean Fuel Synthetic Cleaner is a concentrated 20-ounce fuel-system treatment sold in a convenient six-pack to clean injectors, reduce deposits and help restore engine responsiveness.

This concentrated fuel-system cleaner is formulated to tackle carbon and varnish deposits in gasoline engines. Used as part of routine maintenance, it helps restore throttle response and smooth idling while supporting more efficient fuel combustion. The six-pack offers value for motorists who want to treat multiple tanks or keep a supply on hand for scheduled service intervals.

How does Royal Purple Max Clean remove deposits?

The formula contains potent detergents and solvents engineered to dissolve gum, varnish and carbon build-up without harming seals or sensors. It works as fuel flows through the injectors and intake tract, lifting deposits so they can be burned away during combustion.

• Concentrated 20 oz bottle treats multiple tanks depending on application.
• Safe for oxygen sensors and catalytic converters when used as directed.
• Designed to clean injectors, intake valves and combustion chambers.

Will using this cleaner improve performance or fuel economy?

Clearing deposits can restore lost responsiveness and smooth out irregular idling, which may help the engine run closer to its original tuning. While results vary by vehicle condition, regular use as part of preventive maintenance supports consistent performance.

• Helps recover throttle response often dulled by deposit build-up.
• Can reduce rough idling and hesitation under acceleration.
• May improve fuel burn efficiency when significant deposits are present.

How and when should I use the 20 oz bottle?

Follow the product label for exact dosing; typically, add one bottle to a near-empty tank, then fill with gasoline to mix the cleaner evenly. For heavy deposits or older vehicles, repeating treatment over two fill-ups can give better results.

• Add to fuel tank before filling to ensure complete mixing.
• Use one bottle per tank for standard maintenance; consult label for high-concentration needs.
• Safe for regular use at recommended intervals to maintain a clean fuel system.

What makes this six-pack a practical choice?

Buying a six-pack reduces per-treatment cost and eliminates the need to purchase single bottles frequently. It’s convenient for households with multiple vehicles, fleet operators, or drivers who prefer to keep a spare at hand for seasonal or long-trip maintenance.

• Six 20 oz bottles provide multiple treatments for one or more vehicles.
• Bulk packaging reduces cost per bottle versus single purchases.
• Compact bottles are easy to store in a garage or maintenance kit.

Who is this for? Royal Purple Max Clean Fuel Synthetic Cleaner is suited for car owners, fleet managers and automotive hobbyists who want a concentrated, professional-grade product to address fuel-system deposits. It’s appropriate for gasoline engines in passenger vehicles, light trucks and performance cars where restoring injector and intake cleanliness can improve drivability and support consistent combustion.
