"Power loss" is a bit of a short description.
When does it appear? Low revs? High revs? Both cold and warm engine?
Just changing things randomly is not gonna help, or you must be very lucky.
I even think that fuel is not the issue, since most engines are designed to
run on far worse fuel then we can buy in western countries.
