Rzoil 70E Oil Leak Stop - 300 ml

A ready-to-use engine oil additive that stops leaks caused by worn rubber O-rings. It is compatible with mineral and synthetic oils, including low-sulfur, low-phosphorus, and low-ash (SAPS) oils. Its formula regenerates rubber O-rings, restoring their elasticity without affecting oil quality or viscosity. Suitable for gasoline, diesel, gas, and hybrid engines (with or without a turbocharger). One 300ml bottle is sufficient to treat up to 5 liters of oil; simply add it to the engine oil, and the additive will remain in the oil until the next oil change.
