ok here is what the Honda hand book says.....
Page 213.
Petrol models,
your Honda is designed to operate on premium/super unleaded petrol with a research octaine number (ron) of 95 or higher.
Type r model,
use of a lower octaine petrol can cause a persistent, heavy metallic rapping noise in the engine that can lead to mechanical damage.
That is all quoted from the owners manual.
Still going to use 95?????
actually its page 215, but i'll let you off cos 213 is the contents for the fuel section
if you read the page properly it tells you not to use lower then 95 octane...which we don't have in this country anyway
i believe in Europe anything 95 RON and above is considered "premium" or "super" so thats why it tells you to use that
the reason your subaru responded to the higher octane stuff was because it was made for higher octane fuels, and it was turbocharged too
so in conclusion, yes, i'll continue to use 95 RON petrol, as Honda tell you to in their handbook for the car and its been run for 36,000 miles on 95RON fuel with no ill-effect
