http://www.opieoils.co.uk/pdfs/MOTUL/motul-8100-x-cess-5w-40.pdf
what concerns me,is that castrol states that this oil is for high reving engines(so it has to be thick at operating temp) and i am worried it might have an impact to fuel consumption comparing to the xcess that is not so "racing" oil..
any opinions?

The Castrol 0w40 sold here is very light, HTHS of 3.6. The Motul is 3.7 and M1 0w40 is 3.8

There will be no difference in fuel economy.

M1 would be as much a group iv as the Castrol. I have no idea about the Motul. I would choose M1 if the price were the same only because I know more about this oil and what to expect when using it.

High RPM oil need not be as thick as low rpm oil (if there is such a thing)

You are worried about thickness, you obviously know that Mobil 1 is lighter than these two oils. Yes, it's group 3, but, in my opinion, is not a problem. It still remains a great oil.

However Castrol 0w40 FST and Motul X-Cess 5w40 looks quite similar to me...but unfortunately the HTHS value of the Castrol is unknown.

I have seen a lot of good analysis reuslts on the X-cess 5w40 in high-performance Audis (S4, S5, etc).
