I installed this on
Subaru Impreza

Review
Mobil 1 0W40 is the oil that I normally use. It's factory filled oil for GTR35 so it's good enough for most cars.
Have used the cheap Silver 1l bottles of European Formula from Giant and the more expensive 5l Gold bottle from spare parts shop. Somehow, the Gold felt smoother for longer although it's more expensive.

What I like
If it can be bought cheap, it good value for performance

What I do not like
If it's expensive like from ExxonMobil Petrol stations.
