I was wondering if there was any harm in keeping Kreen in my oil for 5000-6000 miles? The reason being I just changed my oil and my first bottle of Kreen just arrived -- I'm too impatient to wait until I'm closer to my OCI! I understand the Kreen burns off quickly but the carbon deposits will be in my oil/filter for a while. I recently changed the valve covers on my vehicle and while there was some sludge (at 170k miles) it was not terrible.
Thanks!
