After I change my oil to Castrol, the whole car seems smooth.

What I like
Smooth and quiet engine

What I do not like
Price tag, its more expensive then my normal Amsoil that I use.

The engine is purring smoothly ever since I started using this oil. Startup is smooth and not harsh, and the engine performance is much sharper and more responsive now. Idling is also quiet and my fuel consumption has reduced slightly with this oil. It's easy to find too.

Good and smooth EO for my K20A engine. Remember to buy the Titanium version, it is better than the normal Castrol Edge.

What I like
Starts to turn brown after 5-6k km, but overall still fairly lasting compared to other brands

What I do not like
Price! You are looking at 110-120 for 4L

Oil change was done using Castrol Edge 5W40. Experience less engine noise, as compared to other EO that I used. Can feel less sluggish when driving off in the morning. Working well when driving. Fuel efficiency is almost the same. Nothing detected. In summary, if you are looking for a reliable and slightly better than the rest, you can consider this EO.

I tried it before and I may go back to it again. My engine just runs very well with this oil. Quiet, smooth and never had any problems with the engine oil drying up/evaporating.

Installed on Mazda 3

My previous oil used was Motul 300v 5W30.

What I like
Engine maintains at low noise. Smooth at operating temperature. For a W40 vioscity, fuel efficiency is considered good.

What I do not like
During cold start, can feel sign of sluggishness when moving off. Experienced slight vibration during cold start up. Price differs a wide margin from different workshops. So check out the price first.
