Hi!
I've used Berryman's B-12 fuel injector,intake valve and system cleaner for a few years. Will using B-60 be too aggressive at this point? Several months ago I replaced my head gasket and removed a lot of carbon from the exhaust valves, especially on the back sides. The intake valves were remarkably clean, which I attribute to my use of B-12. There was and remains an oil burning issue, and I replaced all of the valve guide seals, although they may have been defective. I doubt it, noting Honda's typical OEM quality, but anecdotal suggestions were that the smoke produced is from leaking seals. I'm moreinclined to think I have oil control rings that are bound up due to carbon buildup. I didn't have the chance or really the inclination to replace the rings -- largely because I want to see my beloved 1995 Honda Civic LX run for many, many more thousands of miles without being considered 'rebuilt'. It has 324,324 miles on it.
So, how harsh might your B-60 be at this point? Should I simply keep using your B-12 every so often? I 'guesstimate' usage frequency and amount, as I have a leak spot somewhere in the upper half of my tank and try to not fill beyond the halfway area. Thank You for your thoughtful assistance!
Sincerely,
Bill

Berryman B-60 High Mileage Fuel System Rejuvenator (Part #7516) is a powerful fuel system cleaner but NOT a harsh one. That said, tackling oil control rings from the FUEL side of the engine likely isn’t going to be effective. Instead, you will see better results if you use Berryman B-12 Chemtool Fuel Injector Cleaner (Part #0116) in the crankcase when it can directly interact with the oil control rings.
To do this, you should add 1½-2 fl oz of 0116 per quart of oil capacity to the COLD crankcase. If your engine holds 4 quarts of oil, then you should introduce 6-8 fl oz of the chemical. Then run the engine at idle until it reaches operating temperature, usually 5-10 minutes for gas engines.
This procedure can be repeated multiple times if desired as long as the engine has cooled down between treatments. Also, because 0116 can dissolve sludge and carbon, it’s possible the oil can prematurely become overloaded with contaminants, we recommend checking the oil for darkening after each treatment and changing the oil and filter if the oil becomes particularly dark.
