Using Sea Foam in oil [SOLVED]

I watched a YouTube video that showed adding Sea Foam to the crank case with fresh oil, then becomes super dark and almost looks contaminated after just running for a few minutes. Is it OK to do the crankcase treatment and not worry about the oil until my next oil change?

Hi Dominic. Though I am not familiar with the video you watched, there is no concern when adding Sea Foam to crankcase oil. It also works better when you add 100 to 300 miles before the end of the oil interval.
