Superadditive! Actually works

Initial situation:
In my car, the lash adjusters began to rattle, only very briefly then longer and louder. Only when the engine warmed it stopped.
The hydraulic tappets swap would with 24 valves is not only very expensive but on top of that extremely complex. So I decided to try this "magic bullet".

Granted I was very skeptical, but I must say it works!

The Sequence:
Have the additive simply dumped into the oil and then I drove about 20km. Home parked the car and turned on again until the next day. What has improved? NOTHING!

I should say that one probably I mainly go short distances. A few days later, I noticed that the time in which the hydraulic tappets rattled, has significantly shortened. Over 3 minutes to less than 30 seconds.

Then I drove last weekend twice a slightly longer route (130km). And realized that the clatter After cooling back down completely disappeared. Since then, everything is completely silent again.

My conclusion: a miracle cure that actually works wonders!
