Motul Fuel Injector & Valve Cleaner 300 mL — PEA Formula, Treats up to 60 L

Motul Valve & Injector Clean is a concentrated PEA-based fuel additive that dissolves carbon and varnish from injectors, intake valves and the manifold to restore throttle response, steady idle and better combustion. Motul brings a professional-grade cleaning chemistry to routine maintenance with this 300 mL canister. Designed for modern direct-injection and port-injection gasoline engines, the formula reaches tight clearances to break up stubborn deposits without disassembly. One treatment handles a full tank (up to 60 L), works with unleaded and ethanol-blended fuels, and leaves a thin lubricating film to protect injector needles and valve seats while slowing fresh buildup.

How does this product improve engine performance?

Cleaning deposits that restrict fuel spray and air flow helps combustion proceed more evenly, which restores throttle sharpness and stabilizes idle. The PEA detergents dissolve carbon and varnish that accumulate on injector tips and valve surfaces, improving atomization and sealing where it matters most.

• Dissolves hardened carbon on injector nozzles and valve backs
• Restores precise fuel spray patterns for better combustion
• Reduces rough idle and hesitation during acceleration
• Improves cold-start response by clearing intake and injector deposits

Is Motul Valve & Injector Clean safe for my engine and emissions equipment?

The formulation is compatible with unleaded, premium and ethanol-blended gasoline and is safe for catalytic converters, oxygen sensors and turbocharged hardware when used as directed. It cleans without aggressive solvents that would harm fuel pumps or seals and leaves a protective micro-lubricant to reduce wear on moving parts.

• Safe for catalytic converters and oxygen sensors
• Suitable for turbo engines and hybrid systems
• No special tools or shop time—pour and drive application
• Works with E10, E15 and higher ethanol blends where recommended

How do I use it and how often should I add it?

Shake the can, pour the full 300 mL into a nearly empty tank, then fill with 40–60 L of gasoline and drive normally to let the cleaner circulate and strip deposits. For larger tanks, dose at approximately 1% of fuel volume; repeat every 6,000 miles or about six months, or sooner after filling with poor-quality fuel.

• One 300 mL can treats up to 60 L (about 16 gallons)
• Pour before refueling and drive to allow full cleaning cycle
• Repeat at recommended intervals for preventative maintenance
• Compatible with regular maintenance schedules—no disassembly needed

What measurable benefits can I expect after treatment?

Results vary by vehicle and deposit severity, but owners commonly notice improved throttle response, a smoother idle and easier starts. Cleaner fuel spray and better valve sealing can also support more complete combustion, which may lower fuel consumption and tailpipe hydrocarbons under some conditions.

• Sharper throttle response and smoother idle in many vehicles
• Improved cold-start behavior after deposit removal
• Potential for reduced fuel use due to more efficient combustion
• Slows new deposit formation through a light protective film

Who is this for? Motul Valve & Injector Clean is ideal for drivers who want workshop-level fuel-system cleaning without the cost or downtime of professional services. It suits daily commuters, high-mileage cars, performance vehicles and small fleets that use gasoline or ethanol blends and need a regular preventive step to preserve engine responsiveness and fuel economy. Use it as part of routine service intervals to maintain injector spray quality and intake-valve cleanliness between mechanical cleanings.
