Purpose and Specifications

LIQUI MOLY VISCO STABIL is a high-performance engine oil additive designed to stabilize motor oil viscosity and protect your engine under extreme driving conditions. This mono-functional additive works with both gasoline and diesel engines, preventing oil thinning caused by frequent cold starts and mechanical stress.

Key Benefits:

• Stabilizes oil viscosity to maintain consistent engine protection
• Reduces oil consumption by improving piston ring seals
• Lowers engine noise and vibration
• Maintains optimal oil pressure under all driving conditions
• Reduces engine wear and extends oil life
• Works with mineral and synthetic oils

How It Works: The additive protects against permanent shear losses in your oil, which naturally occurs during hard acceleration, towing, and high-temperature operation. One 300 ml can treats up to 5 liters of motor oil.

When to Use / Replace?

Add this additive:

• When performing an oil change or top-up service
• If your engine shows signs of increased oil consumption
• Before winter driving or frequent cold starts
• When towing or driving in extreme conditions

Application: Simply shake the can well and pour the entire 300 ml into your engine oil. Allow the engine to run warm for proper mixing. The product can be added at any time—no special procedures required. For a 5-liter oil capacity, one can provides complete treatment.

Compatibility: Safe for all turbochargers, catalytic converters, and diesel particulate filters (DPF). Not suitable for motorcycles with wet clutches.
