Another similar product is Mopar Combustion Chamber Cleaner, also labeled as Combustion Chamber Conditioner. Comes in a spray can application which some find simpler.
-Drive until engine warm.
-Disconnect rubber throttle body intake from TB.
-While idling, spray entire can into TB opening, increasing throttle just enough to prevent stalling.
-When can is near empty stop spraying and shut off engine immediately.
-Let sit for 10+ minutes.
-Start & idle 5min while waiting for white smoke to clear.
(More may appear once you drive and load the engine.)
Regardless of cleaner brand or form, if you want to be thorough it takes a direct cylinder application and soaking. That means several hours or overnight. Direct application to the cylinders is the best way to clean ring deposits, even free stuck rings. This can reduce consumption and really help compression. Do this BEFORE the above procedure:
-Remove the plugs and spray 2-3 seconds in each cylinder. If liquid, pour 1oz. (I use a small funnel stuck into fuel line that goes into the cylinder.)
-Let sit, ideally overnight. At least long enough to allow the cleaner to drain or evaporate and not hydrolock the engine.
-*safety step if impatient or not sure* Cover the engine, or at least the plug openings with a towel. With the plugs still out, bump over the starter a few revolutions. This helps remove any remaining liquid from the cylinders. The towel will prevent any excess from creating a mess. *
-Replace the plugs, warm it up again and do the first sequence.
It's a good idea to change the oil after completing one of these flushes. The solvents break down the oil and hasten oxidation. Used directly in the intake, they also clean enough ring/cylinder deposits that some nasty junk will get into the oil, further messing with its chemistry. These treatments can also contaminate your plugs.
After a few years of doing this type of work you'll learn to work it into your normal maintenance schedule so you do it right _before_ the oil/plugs/O2sensors. Depends on the engine mileage & condition of course. If there's less junk to clean there won't be as much effect on oil/plugs/sensors. But then very few people with a 1-2yr old vehicle need to use these products.
