I can confirm what Cstavaru said: Motul 300V Power oils are the best of the best. May not last as the 8100 oils, but if you can afford the chnage your oil in every 5.000 - 8.000 km, than it is the best.
I'm leaning towards the Motul 8100 X-Cess 5W-40 and yes I always changed my oil at 5,000 miles. The 300V is a little over kill lol
