he is referring to adding to seafoam to the oil guys, and even though your not hitting that 200 miles or whatever you are still running the engine and the seafoam is circulating no matter what and it will clean what is in there. I ran it in my oil for about 175ish miles before I got it changed and it came out black as hell on a 40k mile motor. if you drive those 70-80 miles per wekk I would say drive it all week and then maybe the weekend a little driving and change it before the next work week starts. your going to be surprised how much this seafoam actually helps after doing it. im going to seafoam my 63 when I get home and that should be an interesting ride none the less.
