Review
Got this engine oil after being recommended by my friend, and I would love to try new stuff to evaluate which products are good for my car. Went ahead to try this engine oil, and I found it to be such a good, smooth oil. While stopping before the white line at the traffic light, my car vibrates very little, which means the engine oil had done its part to lubricate engine parts to perform better. Taking off from the line was also good, providing just the right amount of power and traction to get my car off the line. Rides around town now is much smoother and comfortable(due to lesser vibrations).

What I like
Awesome oil for the drivers who want utmost comfort and cruising performance.

What I do not like
Quite an expensive oil

Review
I had downgraded from fully-synthetic to this Ducatus 10W40 Semi-Synthetic API: SN/CF, and I have to say this engine oil is perfect for its job. Gear shifting isn't much of an issue, not as what I expected from a semi-synthetic, for it actually gear shifts smoothly! There is very minimal vibrations and noise while idling, but all of this for a cheap price, I would want to vouch the Ducatus 10W40 Semi-Synthetic API: SN/CF!

What I like
I just love how cheap this engine oil is, and performs almost as if it was a fully-synthetic.

What I do not like
I wasn't used to using semi-synthetic, so I felt slightly heavy at the front boot. Got used to it after some time.
