I wouldn't call myself brave.....willing to experiment maybe... but I have done this on two leakers and its worked both times.
My friend was the chief mechanic for a small local sprint car race team, and he added brake fluid to oil all the time and swore by it. He was a little nutty though. Actually still is.
About ten years ago my 1995 Toyota 4Runner was putting a quarter-sized oil stain on my driveway daily due to a bad rear main seal. My emotional commitment to this truck had long expired, so I added 3-4 oz. of brake fluid and within a week or so the leak completely stopped. I ended up keeping it and drove that truck almost daily, including a lot of towing, and it never leaked again until I traded it in a year or so later. The mom and pop dealer I traded it in to, sold it to a friend of theirs. I stopped in to that dealer about a year later looking at another car and I asked about that 4Runner and they said the guy they sold it to was still driving it.
Did it again a while back on a friends beater Camry that was leaving three or four quarter sized drops daily. It didn't stop completely but now it leaves 1-2 dime size drops. That car still gets driven daily to this day.
That being said, I wouldn't recommend anyone else do this, at least not to a car they care about.....
Well if it worked, it worked.
But a quarter must be an impractically large coin to have made that a reasonable gamble, say about the size of a hub-cap.
You must have very big pockets in America.
