Review
Used it on my previous Jazz at about 130k mileage.

Pick up was better. Smoother rev.

But won't recommend for new cars. More for aging cars.

What I like
Better pick up and smoother rev

What I do not like
Not cheap

I installed this on
Volkswagen Jetta

Review
I used this product when I changed my oil. It works perfectly. I followed the directions exactly. It had cleaned so much sludge out of my engine. There's still abit more in the bottle for me to use it one more time, but then I don't think I will need it again for a long while. I bought my car used, and when I changed my oil, I noticed that the oil always came out black. I change my oil every 4000 to 5000 miles. I spoke with my mechanic, and he told me my engine was probably very dirty. After using Liqui Moly Pro-Line Engine Flush, my car is running just like the day I bought it from the dealership. My car is almost ten years old, with 125000 miles on it! Needless to say, I love the stuff. Liqui Moly Pro-Line Engine Flush brought all the pick up back into my car.

What I like
I simply love the fact how it had restored my engine health back to optimum condition.

What I do not like
The price.
