I have used this Nulon Stop Smoke before. But I didn't buy it to stop engine smoking. I bought it to help stop a noisy hydraulic lifter tapping . The engine I just serviced had gone 15000kms over schedule. Fresh oil and filter change, a bottle of Stop Smoke and a good drive and the stubborn lifter is now quiet...

This product is claimed to reduce oil consumption so I will monitor the oil usage at 1,000 km intervals.
Definitely works and is worth using for smoke coming out the exhaust. Only temporary measure until things are fixed
It’s hard to get out of the bottle…… must be squeezed and shaken
Nulon Stop Smoke - 500mL works very well and can be recommended to all. Enjoy!
Works well but too expensive! It used to be around $6 in Kmart now nearly $20 at Repco!
It works! 2012 Defender always started with a plume of smoke now gone. Worked immediately.
A good old product to reduce the smoke being emitted from engines. I used this on my rideon mower which was blowing lots of smoke after the wrong fuel was put in. Three months later, is still going.
