Just a small update.. I thas been 612 miles sice I added Kreen. My valve ticking when warm or cold seems to be gone. No change in my light "thumping" sound on a first cold start of the day that is gone after two minutes or less. I think it is a worn valve timing unit (vanos). A clean engine will not fix that.
Oil is getting a little darker per a blotter test. Not sure there was a lot of crud in the engine prior to Kreen except varnish which, per other posters, can cause valve tick etc. This car had 2-3 Auto-rx treatments and at least one MMO in crankcase treatments.
I do not see any burn-off of kreen as oil level has not reduced to any measurable level. Keep in mind BMWs are very tight engines. They even run different if the dip stick if left out as it creates a vacumn leak. Pehaps this is why no burn off.
Anyway my observations.
