Liqui Moly Pro-Line Oil Loss Stop – The Professional-Grade Solution for Engine Leaks
Tackle troublesome oil leaks and reduce excessive oil consumption with Liqui Moly Pro-Line Oil Loss Stop. This advanced, professional-grade additive is engineered to rejuvenate hardened and shrunken rubber and plastic seals within your engine, restoring their elasticity to stop leaks at the source. It provides a reliable solution for environmentally problematic oil patches in your garage and puts an end to clouds of blue exhaust smoke .
✨ Key Features & Benefits:
-
Rejuvenates Engine Seals: Effectively regenerates and maintains rubber and plastic seals (such as shaft seals and valve stem seals), restoring their flexibility to stop leaks caused by aging and heat cycling .
-
Reduces Oil Consumption: Works in two ways: by reducing consumption through piston rings via consistent viscosity and through valve guides by regenerating the seals .
-
Eliminates Blue Exhaust Smoke: Prevents the blue, smoky exhaust fumes that are a classic sign of oil being burned due to leaking valve stem seals .
-
Enhances Engine Performance: Counteracts the loss of viscosity in motor oils and can lead to a quieter, smoother-running engine by dampening mechanical noise .
-
Universal Compatibility: Suitable for all gasoline and diesel engines, including those with or without a diesel particulate filter (DPF). It can be safely mixed with all commercial engine oils .
️ Areas of Application:
Ideal for use in a wide range of vehicles to address:
-
Leaking engine seals and gaskets
-
High oil consumption
-
Blue smoke from the exhaust on startup or acceleration
How to Use:
-
Dosage: The entire 1-liter can is sufficient for an oil system with up to 15 liters of motor oil. Do not exceed a 10% additive-to-oil ratio to prevent potential engine damage .
-
Application: The product can be added to the engine oil at any time. Simply pour it into the oil filler neck .
-
Activation: After adding, run the engine until it is warm or drive the vehicle as normal. The sealing action typically becomes effective after approximately 600 – 800 km of driving .
-
Maintenance: For a lasting effect, it is recommended to use the additive again after every oil change .
