JLM Stop Smoke Oil Treatment

JLM Stop Smoke Oil Treatment is the best engine stop smoke additive around. Our stop smoke oil simply reduces smoke from the exhaust caused by burnt oil. The active formula in this additive reduces unwanted play between worn engine components such as piston rings and valve seals and makes oil seals more supple, allowing them to seal optimally.

The engine compression ratio also increases because the components of the engine are optimized by Stop Smoke Oil Treatment. The result of this is a better performing engine with more power and lower fuel consumption.

The viscosity of the oil increases because of the concentrated composition of the additives package. This ensures that the oil adheres more effectively to the moving parts in the engine and improves lubrication. The result is that the engine's service life is prolonged considerably.
