## Questions & Answers

**Q: is it for diesel? where does it say that?**
A: Yes diesel

It really works

**Q: Anyone try on a bmw n62 engine?**
A: Yes! It did stop the smoking for the past few months. It's cold out now so can't really see if it's still in effect.  Do oil changes every 3k and change oil weight to 10 40, the thicker oil helps with the valve seals. 

07 X5 e70 4.8  270k 😉

**Q: Can this be used on small engines like 6 Hp? If so how much do you add?**
A: Hello.
Add contents to the oil when engine is warm. To obtain a good mixture with the oil after adding it, let the engine run or drive with the car for 5 minutes.
 Use at oil change or between oil changes as needed.
  1 metal can of 325 ml treats 3 to 6 litres of engine oil.

It is instruction gow to use. O think you need to divide your oil capacity, if your engine is small and during oil replacement you are using only 1litre of oil, you should use this product arround 50-80ml.

**Q: Do i add to existing oil or drain some n replace with this?**
A: "USAGE INSTRUCTIONS
*It should be added to the oil while the engine is at operating temperature. After adding for the ideal mixture, the engine should be run for 5 minutes.
*1 box (350 ml) of Wynn's Smoke Reducer should be added to 5 liters of engine oil.
*It can be used between oil changes or as needed."
