BOSTON ENGINE STOP LEAK 354ML

Boston Engine Stop Leak is a chemical additive designed to reduce or eliminate oil leaks in petrol, diesel, and LPG engines. It works by revitalising hardened or brittle seals and gaskets (such as the rear main seal) to help them regain their flexibility and original shape.

Key Features and Symptoms it Addresses
Leak Reduction: Formulated to control engine oil leaks from deteriorated seals and gaskets.
Blue Smoke: Helps stop blue smoke emitted during start-up, takeoff after idling, or when decelerating downhill.
Oil Consumption: Reduces excessive oil consumption and the need for frequent top-ups.
Compatibility: Suitable for all petrol, diesel, and LPG vehicles, and compatible with mineral, semi-synthetic, and full synthetic oils.

Application and Expectations
Temporary Fix: It is intended as a temporary repair to extend the engine's life or manage a leak until a mechanical repair can be performed; it does not replace the need for physical gasket replacement.
Effectiveness: It is most effective for small leaks caused by seal hardening. It will generally not fix leaks from mechanically damaged or collapsed seals, or larger holes.
How to Use: Typically added directly to the engine oil. After adding, it is recommended to drive or idle the vehicle for 15–20 minutes to allow the product to circulate.
