Wurth Oil Smoke Stop (300ml)
Eliminate trailing blue exhaust emissions, stabilize oil performance, and heavily reduce internal oil burn rates with the high-performance Wurth Oil Smoke Stop (300ml). As internal combustion engines accumulate high mileage, natural mechanical wear creates microscopic gaps between piston rings, valve guides, and cylinder walls. This clearance breakdown allows engine oil to seep directly into hot combustion chambers, resulting in continuous oil burning, heavy carbon crusting, and signature blue exhaust smoke emissions. Wurth targets this core issue using a highly advanced chemical blend engineered to restore vital oil film structural integrity.
Wurth Oil Smoke Stop functions by actively stabilizing and optimizing your engine oil's viscosity index under severe thermal conditions. It compensates for natural viscosity degradation and structural losses caused by extreme engine shear stress, sealing high-tolerance boundaries without thickening the cold-cranking performance of your oil. This structural seal prevents oil from bridging past rings into the combustion cycle, which directly minimizes engine oil consumption, cushions valvetrain acoustics, and protects downstream exhaust filtration networks from premature fouling.
Key Product Features & Performance Benefits:
- Prevents Blue Exhaust Smoke: Chemically blocks motor oil from bypassing internal rings into cylinders, putting an immediate stop to blue exhaust smoking.
- Stabilizes Oil Viscosity: Compensates for severe viscosity breakdowns and heat losses, ensuring a robust, protective lubrication layer remains intact under heavy loads.
- Lowers Oil Consumption: Visually reduces the rate at which your engine burns through oil between service intervals, saving you money on constant top-ups.
- Highly Versatile Application: Engineered to blend seamlessly with all commercially available mineral, semi-synthetic, and fully synthetic engine oils.
- Dual Engine Compatibility: 100% safe and highly effective for use across all high-mileage or worn petrol and diesel engine architectures.

How to Apply / Usage Instructions:
- Wurth Oil Smoke Stop can be added directly to your vehicle's engine crankcase at any point between service intervals, or immediately following a fresh oil change.
- Ensure the engine is switched off. Unscrew your engine oil filler cap and pour the entire 300ml contents directly into the engine crankcase.
- Replace the oil filler cap securely. Start the vehicle and let the engine run until it is completely warm to ensure the additive blends thoroughly with the base engine oil.
