Tried this oil now, but was dissapointed from my previous oil, which was Castrol Edge Sport 0w-40. When i filled Motul 8100 x-cess 5w-40 I instantly noticed reduced acceleration, like there was more friction in the motor compared to castrol. It was obviously also more noise from the motor. The car also use a tad more gasoline with the motul oil compared to castrol and the temperature gauge really increased from lets say "7.55" to "8,50" oclock - a several degrees increas in engine temperature. So, I would say this is not a true performance oil, there are for sure better oils around.
Not to mention this is a 5w oil which usually means more wear during startups compared to 0w, specially if driven hard and/or in colder climate until engine is warm. Though reduced viscosity range also is said to make it more shear stable and more rigid, but this is today more related to the quality of the oil itself,
