It has a lower viscosity than normal service engine oil yes, but that's a necessary feature of an oil designed to flush. Secondly, even though Thanos' engine might be "properly maintained" according to the manufacturer's schedule, in arduous conditions such as his occasional use of
Flush Out contributes to a high standard of maintenance. To say that Comma
Flush Out has a viscosity close to tap water is an inaccurate exaggeration.

I have used Comma
Flush Out on all my cars over several decades with no adverse effects whatsoever. On the contrary, I have found it to be highly beneficial. Over thirty years' ownership of my SD1 and 180,000 miles I have never had to undertake 'short' engine repairs. It's running on the original camshaft and hydraulic tappets. Any traces of flushing oil remaining after a treatment, which will be minor owing to its low viscosity, clearly do not constitute "contamination". I'm afraid that I don't recognise your rather dramatic claim at all.
