I installed this on
Volkswagen Jetta

Review
I had previously encountered jerky gear shifts, slower acceleration and power delivery wasn't so good. After changing to this Liqui Moly Diesel High Tech 5W-40, I noticed a significant change in gear shifting which is now much smoother, acceleration was gradual and quick with no hiccups, and I now have more power. I have been using this for a year now, and what I realized was that my engine parts do not require much maintenance or doesn't give any funny signs that its failing at least.

What I like
The enhancement in the engine's performance and health was such a great turn on.

What I do not like
These are quite difficult to find.

Review
I change my oil every 10k km and somehow, this oil still comes out looking pretty clean. I've been using it for close to 3 years now and my car has never had a problem and my engine's running very smooth. One of the best oils out there.

What I like
Oil stays clean and effectively lubricates my engine well

What I do not like
None
