Ideal for older engines
I had a very slight oil leak and this product solved the issue after a couple of days of driving. It's not a permanent solution but so far no more leaking. Not sure how this would perform on more serious leaks.

يجب استعماله على فترات متفرفه مثل كل ثلاث ايام 250مل ولمدلاتقل عن اسبوعين مع عند إضافة زيت المحرك 1لتر نص اذا كان ناقص . وعند استبدال زيت المحرك يضاف 1 او 1.5لتحصل على أفضل نتيجة.

This product has been negatively reviewed far too many times, and I felt compelled to write a review on it. I have used this product on 3 cars with oil leaks, and my family has used it on their cars as well. My family has had great success with minor oil leaks, and 2 of my 3 cars I have used this on resulted in their oil leaks ceasing completely. My other car turned out to be a decent sized crack in my oil pan gasket, which explains why throwing some Stop Leak at it didn't solve my issue. This product helps greatly to repair old, hardened seals, but it doesn't falsely advertise to bring about miraculous results in moderate to major issues. My point is, this product works extremely well for it's intended purposes, and I feel that all of the negative reviews should be taken with an grain of salt. It would be spectacular to hear, from the negative reviewers, what sort of issues ended up being diagnosed in the cars this product didn't help. I'm by no means trying to put down the negative reviewers, but it does get a bit frustrating reading reviews on Amazon like "Put it in my car, didn't work, still leaking, crap product" or "I contracted a flesh-eating bacteria, and this 'highly rated' Neosporin didn't work. Don't waste your time. 1 star. Booooooo!!!!" Lucas Stop Leak is a great product for it's intended purposes, has been used and trusted by amateur and professional mechanics for years, and fully deserves a solid 5 stars.
