So was curious, since my accord is the first turbocharged car I’ve owned. Is it better to use a higher octane fuel? Or does it really not matter?
Regrettably that's no longer true with Gasoline Direct Injection (GDI) which along with the turbo is how you get 192 horses out of a 1.5 liter engine. The gasoline is spritzed directly into the cylinder, the valves only let air in and out.Better in what sense?
The ECU will allow more spark advance and maybe a little more boost with premium gas. That will translate to more power. Not huge amounts, but some.
As long as you're using a top-tier brand of gas the additive package will be the same between regular and premium, so both will help keep your valves cleaner.
Makes a huge difference to the pocket book, 50c a gallon is non trivial. GNIf anyone is interested, KTuner dynoed a base 2.0T Accord in various states (87, 93, Stage 1 tune, Stage 2 tune, against the Type R). There is a modest bump in power in using 93, but does it make much of a real word difference? probably not.

Very interesting. It would have been nice if all their labeling also included blue = and green = to identify which is which. Maybe they visit here and will note that for the future.If anyone is interested, KTuner dynoed a base 2.0T Accord in various states (87, 93, Stage 1 tune, Stage 2 tune, against the Type R).
