Using any type of flush or cleaner in the crankcase should be an absolute last possible option if you are trying to revive and engine you don't care about destroying. I personally would not even run this through the intake but to each their own. Proper maintenance and proper on time oil changes will keep the engine clean.

An extra 25 miles per tank is hardly an improvement that I would find noteworthy. I am not calling you out, but I can easily change my mileage per tank by either driving like a maniac or like an old lady and get 50 miles more or less in this manner alone.

I have never been a fan of Seafoaming an engine and I personally will never be one. I don't like adding any chemicals other than factory specified fluids to me engines. Cleaners and flushes have just as much potential to do harm as good.

I love Seafoam. I only use it in the gas tank on my Stang. But on my 99 Mitsu Mirage I use it in the intake vacuum hose, the crankcase and the fuel. Any time the one lifter starts to stick I suck it in through the vacuum hose and its free for a couple thousand miles. I too made a giant smoke screen. I add it to the oil 100 miles before an oil change. The Mitsu is at 177K and since being Seafoamed idles smoother gets better gas and has a quieter valvetrain.
