      It doesn't appear to have stopped the leak but I'll give it a day or so. Might buy another one and see if that works.

    • leaks or no leaks

      i think many use this for external leaks however this puts somethings right internally almost straight away. I experienced a quieter smoother engine and I don't think that can be a bad thing. ive already covered 500 miles since ive put it in. I think most vehicles up to 2000cc would benefit that are 5 years or older or 50000miles and over.

    • How big of a leak?

      There comes a point when the product is a waste of money. I have reached that point, the oil leak was not to bad a little messy under the engine but no overly so. Result was it didn’t work.

    • Good product

      Significantly slowed down an oil leak which would have cost a lot of money to repair.
