very confusing.. is that normal for you? please look at your manual and you will know what is the normal idle rpm for your vehicle.. with that quality oil, for me, there is no need to add additives anymore.. the problem is clean the sludge first.. LM ceratec ? you don't need it right now..

simple to answer this question.. just add a liitle bit of new oil into a container and then heat the bottom of the container with fire until hot and see and look at the color of the oil will change oil turning black doesn't mean anything add a little ester and see the color after a while UOA...
