My 1995 Nissan Sentra was using about a quart of oil overy 200 miles and getting oil all over my driveway. It has 104,000 miles on it. My mechanic said I had quite a few oil leaks and it was going to be fairly expensive to fix them all. A friend suggested I try your oil additive and I'm certainly glad he did. I've driven over 600 miles since adding the product and have only had to add a tiny amount of oil during that time. Amazing!
