Castrol Edge 0W-40

So good – Been running this in my bmw for 12 years and now at 331,000 km the engine still is like brand new no rattles or anything !!! Great stuff !!! Would recommend to everyone much better than most other oils I believe this is a group 4 synthetic so one of the best made !!!

Only good as an engine flush – I used this product for 1,000km in a 2008 Toyota Kluger with 10,000km on the clock. The oil was given to me by the Castrol rep and he promised me it was the best. As soon as I started using it in the engine i would get valve train noise on start up every time. Having not experienced the issue when using Mobil 10w/40, I dumped the castrol oil, refilled with the trust Mobil and the noise went away. I will never run this rubbish in my engine again.
