u sure or not bro?? my experience is the exact opposite. i've been pumping primax 95 on my other car the majority of its life, then i switched to BHP coz it meets euro 5 standard thinking it would be good.
performance was terrible. felt like i lost 10-20hp.
then it struck me, euro 5 standard has nothing to do with car performance, its about emissions. to reduce emissions, they probably reduced the dirty stuff that gives power to a car so it makes sense for the fuel to be less powerful.

cant remember which but either way its an emissions standard, not performance standard.
