Review on Bar'S Leaks High Mileage Engine Repair, 16.9 Oz by Dale Toth

I’ve used many oil additive products, including Lucas and even other Bar’s Leaks products, and none of them worked as well as this one. I own a 2001 Ford Expedition, that had a fair amount of oil leaking out (around a quart or better a month). I put this in with one of my oil changes, and I haven’t seen a drop of oil since. Great product worth every penny.
