Default Sea Foam in the crankcase

I've put Sea Foam in the crankcase before, but I never really knew what it did.

I won't be doing an oil change until the weather warms up some--don't need to anywaycuz I haven't been putting tons of miles on the civic. My concern is that the Sea Foam will sort of liquify or act as a thinner to the oil in the crankcase. I know it doesn't harm anything inside there. But if I'm not going to be doing an oil change for a while, is it wise to pour that stuff in there?? (I've got about 1 3/4 cans left over in my garage).

Default RE: Sea Foam in the crankcase

I would only run seafoam through the systema couple hundred miles before my next oil change. Let it cycle, do its thing, then dump the stuff out and put in new fluids.
