I think that a trial will tell you more specifically if it has any major performance change I think it will give a better transition running and that your plug will be cleaner; now i am not sure that if in your country the way that they increase the octanage is by means of adding some kind of alcohol because here in the U.S. the achieve that by adding either Methanol or Ethanol to the petrol as much as 10% of it, so give it a try and please let me know the results that you obtain so we can compare!
By the way I do also work in a lab I am a Chemist for a diagnostics company, what kind of work do you do?
