Review on Bar'S Leaks High Mileage Engine Repair, 16.9 Oz by Don Santos

I’ve bought and used this product twice, when doing my own oil changes. It has settled down my oil leak (while not stopping it completely), and fresh oil seems to retain its consistency for a longer period of time.Since I’ve only just started using this product, it can’t be the reason why my ‘05 Honda Civic is still running well at 426,000 miles, but it’s certainly the product I’ll continue using to condition a tired engine, which would otherwise not have TOO much life left in it, (presumably!).
