PROFI-CAR Oil Loss Stop 300ml

PROFI-CAR Oil Loss Stop is an engine oil additive specially developed to help reduce oil loss caused by hardened, aged, or worn seals. The treatment works by helping restore the flexibility and original dimensions of rubber seals inside the engine, including oil seals and valve stem seals, thereby helping improve the sealing performance of the engine without requiring removal of the affected components.

As engine seals age, they can become hard and lose their ability to maintain an effective seal. This may allow engine oil to escape internally or externally and can contribute to increased oil consumption. PROFI-CAR Oil Loss Stop is formulated to soften hardened seals and help them regain their flexibility, supporting improved engine tightness and helping reduce oil leakage through seals.

The manufacturer states that the product can help reduce oil consumption, particularly at high engine temperatures, while also regulating the viscosity of the engine oil. By improving the condition of aged seals and supporting better engine sealing, the treatment may also contribute to improved engine compression and smoother overall engine operation.

PROFI-CAR Oil Loss Stop is suitable for gasoline, diesel and LPG engines, including engines equipped with turbochargers or catalytic converters. It can be mixed with commercially available mineral or synthetic engine oils, making it suitable for a wide range of passenger-car engine applications. The manufacturer also states that the product does not clog filters and is not harmful to catalytic converters.

In addition to addressing oil leakage and consumption, the official product information lists several secondary benefits, including helping reduce blue exhaust smoke, reducing engine noise, and reducing the emission of hazardous exhaust gases. The technical data sheet also states that the formulation does not contain harmful solvents or solids.

PROFI-CAR Oil Loss Stop is therefore intended as a practical engine oil leak treatment and seal conditioner for engines where hardened seals are contributing to oil leakage or increased oil consumption. It is added directly to warm engine oil, preferably shortly after an oil change, and remains part of the engine oil system during normal operation.

It is important to distinguish between oil loss caused by hardened or aged seals and oil loss caused by mechanical damage, cracked components, or severe engine wear. An oil additive can support the condition of suitable seals, but it should not be considered a replacement for mechanical repair when a component is physically damaged.
