about seafoam
Seafoam is just a petroleum based solvent/cleaner. It has been well respected in the automotive repair industry for around 30 years, for good reason. It will not harm sensors, gaskets, or seals. The reasons for using it are well founded. Oil tends to leave carbon deposits on certain areas of intake, exhaust and valvetrain as it heats to a vapor and cools, also know as coking. Synthetic oil does this much less. The built up deposits slow airflow, alter the heating and cooling characteristics of valves and manifolds, and affect engine performance. Seafoam dissolves the carbon deposits-that's all the magic there is to it. It won't make it run better than new or repair engine wear and damage. Removing the carbon is possible by other means, after disassembly and lots of labor. It won't magically give your engine more power or torque than it had when new, but the removal of the carbon deposits will result in a restoration of the engines various parts to condition more like when it was new, and had little to no carbonization, which yields a gain in performance. I've used it in all my vehicles for about 18 years and recommend it to anyone. Read and follow the instructions and you can't go wrong. As far as "polluting your neighborhood", your engine will pollute less after a good Seafoam treatment, since it will be closer to original engineering specs and tuning. Just my O2.
