Fuel!?

[MikeLYR27]

Had my R27 a month now, but filled up on standard BP and it drove really good, Really tourqy and punchy.
Filled up with optimax yesterday and for some reason it doesnt feel as good?
Which i find wierd coz in my 182 it made a difference.
Could it be coz its a fresh engine on 2000 miles?
Or just because maybe new engines compensate for lower grades of fuel?:S
Any one else had the same experience in a 197 or anything else?

What do you normally fill up with?

I did normally fill up on optimax, but its gettin a bit costly now. So have been filling up on regular BP and it felt really strong through out. Put a tank of optimax in yeasterday and slightly dissapointed.
