I've seen a couple posts here re. a brake fluid cure for leaky engine seals. That is, add 6 oz brake fluid to the engine oil, change out after 300 miles - it rejuvenates the seals. Improvement to be seen after about 100 miles.

Has anyone had success or failure with this treatment?

This could be useful for me, as Sven has been leaving 4-6 inch puddles on the pavement when parked. Please, no analysis, it's the rear main seal. Definite.

I'd like to change to synthetic oil for the winter - With regular oil, I need a change every 3K miles or 3-4 weeks (long commute). It's no fun in the New England winter. Synthetic should get me through the season without oil changes. But I don't really want to feed a leak at the price of synthetic oil.

TIA
