VALVEX

Lead substitute additive for gasoline and LPG/CNG XENUM VALVEX

XENUM VALVEX is an innovative fuel additive that serves as a lead substitute in unleaded gasoline. Specifically designed to protect valve seats and valve faces from damage and wear when the engine operates on modern fuels (gasoline, LPG, CNG). The product forms a durable protective film on the valves and their seats, similar to the one formed by lead in leaded gasoline. This provides reliable lubrication and prevents micro‑welding, which is critically important for earlier‑generation engines.

Key properties:

• Protects and lubricates valves and their seats.
• Prevents valve seat recession.
• Makes engine operation smoother.
• Increases engine reliability.
• Protects the fuel system from corrosion.
• Safe for catalytic converters.
• Does not affect octane rating.

Applications:

Recommended for all 2‑ and 4‑stroke gasoline engines (with or without turbocharging) that previously required leaded gasoline and are now operated on unleaded fuel. Ideal for classic cars, retro vehicles, as well as engines running on gas (LPG/CNG).

Usage instructions:

Add 25 ml of the additive to 25 liters of gasoline (ratio 1:1000) in the fuel tank before refueling.
