I have seen your product mentioned by a few people on forums I am in, and want to try it to help with my oil consumption in a 2016 VW Tiguan 2.0 turbo. All of the posts I have read said how great it worked, but when I searched alone, google AI (or whatever it is) said that I should not leave it in overnight because it will break down the paint in my oil pan an send that through my engine. I just need an idea of how long to do a piston soak

Here are the formal instructions for doing a piston soak
We recommend the following procedure - Take out the spark plugs and pour 1/4 can of Berryman B-12 Chemtool Fuel Injector Cleaner (Part #0116) into each cylinder. Thread the plugs back in finger-tight and let them soak for at least an hour, longer if it's much below 65°F (overnight would be fine). Don't worry about leak-down. When you're ready to remove the cleaner/carbon mixture, it's ideal if you can blow a little air into the liquid immediately before suctioning the mixture back out. This will help suspend any loosened carbon. If there is leakage of the 0116 into the crankcase, that is not a problem.
