Rated 3.8 out of 5 by 6 reviewers.
Rated 4 out of 5 by product works for my application installed now for about three weeks noticed small leak to be gone August 25, 2016
Rated 4 out of 5 by Made it better Used noleak about a month ago on a leak that I had was leaving a small puddle on the driveway. I still have a small leak but the puddle did get smaller so it worked a little. Not sure if adding another will finish the job or maybe just take it in to get looked at June 19, 2016
Rated 5 out of 5 by Tried it on my truck Have had a small persistent leak in my Ford F-150 and added no leak I bought from an auto parts store. It's been about a week and i don't see the leak any more! June 19, 2016
Rated 1 out of 5 by Still leaking Doesn't do anything. June 26, 2015
Rated 5 out of 5 by This product is excellent I couldn't believe that my engine oil leaks could be reduced in the manner that they were. However, for one week, my engine did not leak. My engine had big leaks (about five of them), and now, the engine still leaks, however very little. I maybe should try another bottle? Great product. September 20, 2014
