I think you're right - need to do a filter analysis.
I've used it a number of times but have way to validate it - seems legit to me!
Not surprised by the results. Mild solvent w/high dose of detergents. Won't hurt anything because it's not very aggressive. How could it? I also suspect that people who use these products tend to over maintain their vehicles so the engine internals would be cleaner vs the population as a whole.
Old school Gunk engine flush(and the stuff sold at Jiffy Lube) is basically kerosene and butyl cellosolve. LM is using calcium sulfonate as the detergent along with solvents to soften up sludge.
I’m always mystified that with your nearly obsessive use of expensive oils and additives along with your frequent OCIs that you somehow still need a flush, and somehow see that it does anything.
Those deposits man...hahahahha
I have a car that’s nearly always had good full synthetic in it for nearly 200k and it developed a tick ( probably lifter) I decided to just do a quick 5 min flush and see if it helped. used minute clinic from Walmart and it did stop the tick. Hasn’t done it for a month now and before that it had been doing it for several months. Wish I did it sooner. I visually sampled the oil before and after and the after was much much darker. In fact the before, just as has always been the case when dumping the oil, was just barely brownish. The after was dark brown. The color of the flush was not dark. For those 2 reasons, the lifter tick fix and significant difference in color after 5 minutes of flushing, I conclude that “high quality synthetics” also leave deposits. So a flush every once in a while seems like a reasonable and worthwhile thing to do in some cases.
That's true. No matter how good the oil is, deposits will find its way to the crankcase. I used LM flush a couple of times in a cheap fresh oil just to see how dark it might turn, I was actually doubtful LM flush will do anything, but I was wrong. First drain was very dark in just 10 minutes of idling, second one drained like it went in.
Detergents prevent deposits from adhering to surfaces and keep them in suspension while dispersants prevent them from agglomerating, so that they can stay in suspension. Detergents are not designed to remove existing deposits, for that you have to use something polar, like an ester, or a solvent.
Lovely, so all these years I've been misinformed... Live and learn, right?
It happens. People see the word "detergent" and tend to think that it's like a Mr. Clean magic eraser in your engine.
