Do NOT put Seafoam in your oil. It THINS oil to an almost water like consistency. Basically it kills the viscosity. If you have sludge buildup it could dislodge sludge and make things worse. DO NOT use Seafoam if you have even hints of sludge in oil. You can inspect for sludge by opening the large oil screw on the top of the valve cover. Look inside with a flashlight (or remove the valve cover completely). Best time to check for sludge or poorly performing oil is when you are changing out valve cover gaskets.

If you insist on adding it to your oil only put a very small amount like a tablespoon to start with. Do not dump an entire can of Seafoam in the gas tank either, not for the 626, 1/3rd of a can. Remember that stuff is going through your injectors and into your fuel system. It's basically kerosene and benzine with additional detergents. Go slow, do gradual changes. Being impatient and wanting to use a liquid treatment as a repair procedure will only make things worse. Seafoam is not for repair. It's for maintenance. The same is recommended for transmission fluid flushes. You are NOT supposed to do a complete transmission flushing machine because it will stir up sediment and additional metal shavings (especially if your pickup magnet is overloaded). Instead it's recommended to do gradual transmission fluid changes (not flushes) by having it changed every 2 weeks or so about 3 times. The same goes for Seafoam. It stays in the system for a long time so think what happens if something goes wrong? You can't just remove it.

Don't just throw a whole can of Seafoam at an injector, valve, gas, or carbon issue. Gradual is the key. Your doctrine is too aggressive for old cars. If your car is having minor issues that Seafoam might solve be patient and go after it slowly and gradually. Aggressive solutions to minor problems will get your car nowhere fast or worse into a junkyard. The risk isn't worth it. You really need to take that into account when you do this to your car and especially when helping other people with their cars. All cars are not the same even ones that are the same model and year as yours. You might be fine telling a 22 year old guy to go run a quarter mile but you wouldn't tell a 78 year old man to do it. If you tell both of them to finish on their own sweet time I bet both will cross the finish line. Fixing your car is not a race.
