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.

Does not do what it says it can do.
Followed the recommendations of adding the STP Leak stopper exactly. Leak was a very small drip at the start and the situation is exactly the same after three days. What is recommended? Buy more and more Leak Stopper.??? Bit of a con says I.
