I am starting a piston soak with Berryman’s B12 on a 2015 Audi Q5 that is burning a ton of oil. After pulling the sparkplugs I used an endoscope to inspect the pistons. There appears to be metal bits and/or carbon bits at the top of the pistons. I assume this is not normal and would like opinions on whether or not to proceed with the piston soak. Thanks in advance!
