Loaded 2019 Civic Hatch - Regular Fuel

On the 1.5 turbo I would run premium during the summer if you have very hot weather just to be safe on the detonation side, especially if you are doing a lot of heavy traffic driving where the intake air is not coming in very cool. Other than that, run regular if you need to.

I put a tank of 93 in my EX HB last fill and I've noticed a difference in power. Engine seems a bit smoother under acceleration as well.

This is after just about 39K on 87.

I think I'm going to continue to fill with the Premium for next couple of times.

Always premium. Better power, better efficiency, cleaner engine. Worth the extra cost
