Rated 5 out of 5 by Works well and does what it says it will do. Used this product on 1983 Honda V45 motorcycle that had developed a small oil leak when the bike was cold and unused for a week or so at a time. No issues when the bike was hot. I blended just half of the bottle with an oil change due to the small crankcase. Started the bike and allowed a slow warm-up and took about a 20 mile ride. during the warm up while still cold there were a few drops of oil. Since returning from the ride though there has been no further oil leak. The bike has been through several heating and cooling and riding cycles since the treatment and the small oil issue has not returned. Judging this result in cold weather I am pretty confident that there will be no problems in typical warm weather riding. December 28, 2014
Rated 5 out of 5 by This product does what it claims. I was getting oil stains on the garage floor from a small leak. I put this stuff in and the leak stopped. Just what I wanted. Good stuff. November 24, 2014
