MOTUL | Valve Expert Lead Substitute - 250ml

MOTUL Valve Expert Lead Substitute (250ml) is a highly specialized technical chemical fuel treatment masterfully engineered to protect engine valve seats and maintain structural compression in gasoline internal combustion systems. The product is packaged in an ergonomic white plastic bottle integrating an upper graduated dosing chamber with a secure red screw cap, highlighted by a clean red and white commercial label featuring the iconic MOTUL corporate stamp and a detailed structural rendering of an engine valve undergoing mechanical operation. Specially formulated to serve as a high-performance alternative to leaded fuels, this concentrated fluid deposits a resilient anti-wear chemical cushion directly on valve interfaces, completely eliminating metallic friction and heat erosion to preserve vintage and high-load cylinder head configurations.

Specifications:

• Brand: MOTUL.

• Product Line: Specialized Performance Fuel Additives.

• Product Name: Valve Expert Lead Substitute & Valve Protection.

• Classification: Gasoline Valve Cleaners & Valve Seat Protectors.

• Net Capacity: 250 ml.

• Treatment Ratio: Extra-concentrated formula; one 250ml bottle effectively treats up to 250 liters of gasoline.

• Country of Origin: French Republic.

Benefits:

• Professional Technical Lead Replacement: Delivers advanced chemical lubrication properties equivalent to classic tetraethyl lead, protecting valve systems not structurally hardened for unleaded fuel lines.

• Total Valve Seat Recession Protection: Cushions the metal-on-metal impact zones between valve faces and cylinder head seats, stopping structural wear caused by extreme combustion chamber temperatures.

• Micro-Thin Lubricating Barrier Film: Creates a continuous chemical layer that keeps valve stems sliding smoothly, ensuring complete airtight seal calibration during compression strokes.

• Engine Power & Compression Maintenance: Prevents pressure leaks through worn valve guides, successfully sustaining peak volumetric efficiency, smooth acceleration, and stable fuel economy.

• Ashless Ash-Free Thermal Burn: Formulated to ignite and vaporize cleanly without leaving sticky gums or metallic deposits on spark plugs or oxygen sensor tracks.

• Extended Cylinder Head Service Life: Proactively reduces the mechanical stress load on top-end components, preventing expensive, time-consuming engine teardowns and machining repairs.

How to Use:

1. This chemical treatment must be added directly into the vehicle's fuel tank immediately before refilling with standard gasoline.

2. Utilize the integrated top dosing reservoir by squeezing the main bottle body to force the liquid up until reaching the desired calibration mark (10 ml of fluid treats 10 liters of gasoline).

3. Carefully remove the red cap and pour the pre-measured chemical volume straight into the fuel filler neck.

4. Fill up the vehicle's tank with gasoline right away to ensure immediate chemical dispersion and homogeneous dilution ratios across the entire fuel volume.

5. Apply this accurate dosing procedure consistently during every refueling cycle to lock in continuous, uninterrupted anti-wear valve defense.

Suitable For:

• Vintage passenger vehicles, classic sports cars, legacy motorcycle engines, agricultural machinery, and stationary power generators requiring leaded fuel properties or experiencing premature top-end valve seat drying.

Note:

• This trade-grade chemical additive is a highly potent corrective and preventive top-end component stabilizer built to rigorous European standards; to safeguard your vehicle's delicate valves against performance-robbing dryness and compression loss, it is highly recommended to integrate this premium French fluid into your standard vehicle upkeep plan.
