So from my dormant slumber arises a small update... I'll be updating some of my threads shortly.
I have since switched oils on all my M's to now use the Motul X8100 10w60 full synth from the reports and reseach i've done. I'm quite happy with the oil and will continue to use it going forward.
There is not much to report other than that the car is simply bliss to drive.
This is hard to admit coming a from a hardcore S54 fan but the E90M3 to ME is a better handling car and possibly a better drivers car... Bearing in mind this is also a DCT.
Now I am also a huge Manual fan so this does make my personal viewpoint conflicting, as I have the option do drive manual when I want to it's easy to understand why I say this.
Maintenance wise nothing major has been done since ownership other than OEM filters and Fluid changes. Including aircon gas top up. This was done courtesy of BMW Zambezi auto and I personally supervised the whole experience

And pleasantly surprised at the experience. Pics to follow if I can find them...
