What product would be best to treat/clean compression and oil control rings in 4 cylinder engine. Currently uses 1 fl. oz. of oil per 100 miles so I want to stay ahead of this problem. Car has 225,000 mi. Am planning on using B-12 poured in each cylinder over a 24 hour period , rotating engine by hand every 6 hours, then run on highway for 3 miles and change oil and filter. no visible tailpipe smoke at start up or when driving.

It is not recommended to drive the vehicle or run the engine during the piston soak procedure.
The proper procedure for a piston soak is as follows:
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.
