I installed this on
Volvo S80

Review
This was one of the most awesome engine oil I've ever used. Was recommended by my fellow mate to try this after asking him how his car had performed so much aggressively than mine. He provided me a 'sample' bottle by which I was definitely astounded the first time I used it. My car responded much better throttle wise, and driving was so smooth. Also, a bottle of this awesome stuff is quite reasonably priced by what it does!

What I like
Fantastic engine performance booster that ensures smoother and a much more powerful response!

What I do not like
Being not-so-popular, they aren't easy to get. Only certain shops carry them.
