Review
I have been having problem of engine giving out squeaky sound at times especially when engine just started. Not sure if it is due to my vehicle ofter park on slope but it sure is irritation and noisy. Was recommended this by a friend as he explain that this is a very goog lubricating additive and could solve the issue. Decided to give it a shot since got no other cheaper options. When first added the mixture in there wasn't much of a difference but and i time goes the sound gets lesser and lesser. Vehicle vibrate not as hard compare previously and driving seem smoother. And now i totally don't hear anymore of the squeaky noise and fuel consumption seem better too. Will try long term to see how far this product can go.

What I like
No more squeaky noise, smooth drive, reduce of vibration from engine

What I do not like
Cannot find any review from other users, makes it feel a bit risky to use. Might not use if is not my friend recommendation at that time.

This liquid works like a charm. Previously was shown a demo video on youtube on how good this will work. Didn't really believe at first but video shows the people looking at the demonstration were amazed by the test so decide to gave it a shot. It turn out quite well. My engine now makes lesser noise and over the 9 mth and fuel consumption become more economical. Start of engine is smooth even though didn't drive over a period of of a week. Was wondering why no review when the product works.

What I like
engine makes less noise, fuel consumption reduced

What I do not like
very little informtion and review over the web
