Nulon Engine Stop Smoke

I was a bit sceptical, but needed to stop the smoke (wife not happy) - wow this stuff is fantastic – I used this on my Jeep GC 2002 V8 with nearly 200,000km. It started billowing smoke out of the exhaust while idling ( sign of valve stem seal leak) especially after I used a slightly thinner engine oil that was on special. My wife was not happy. I was desperate and decided to try this stuff, despite being skeptical. As such I decided to only put in a small amount (125 ml of the 500 ml bottle) just to test it to see if it makes any difference. It totally stopped the smoke. WOW, I still find it hard to believe how well this worked. I’m a mechanical engineer, and do most of the maintenance on our cars; with absolutely no affiliations with NULON, or any one else. In fact I was going to try another brand, but my local AutoOne store only carried this product. Anyway, it immediately stopped pouring out copious amounts of smoke. I’m a bit flabbergasted as I’m not into oil additives and never have been for many decades. Totally took me by surprise. This stuff totally exceeded my expectations by a mile. This is the most amazing product I’ve come across in many decades of motoring.
