I have a 2022 Sport and usually get about 40MPG. I do about 80% highway driving and I know the Touring has a turbo, but maybe these tips will help you. What seems to help me is watching the ambient meter on the gauge cluster and adjusting my driving style to keep the meter bright green as much as SAFELY possible. An online Civic manual says this about the ambient meter, "With SPORT mode* off, the color of the ambient meter changes to green to indicate that the vehicle is being driven in a fuel efficient manner." If the light is off or light green, then I can probably adjust my driving to get the ambient light showing bright green and therefore get better gas mileage.
The following are specific driving habits that seem to help keep the ambient meter bright green:
1. Very slow, gradual acceleration using light pressure on the gas pedal rather than slamming the gas pedal
2. Smoothly letting off the gas pedal to slow down the car (engine braking) instead of pressing the brake pedal
3. Keeping plenty of distance between me and the car in front of me. The more distance there is, the more I can use engine braking or not brake at all.
I also like to do the following:
4. Turning off the auto engine idle. Normally, I'm not stopped at a standstill for long and I hate the lag from turning on the engine.
5. I got better gas mileage in normal mode vs. econ mode in my parents' 2019 Civic. I'm not sure if it's the same with the 2022, but will test it out some time.
If you do try the above, BE CAREFUL since you will be changing your driving style. For example, you may need to start engine braking earlier vs. using the brake pedal. Anyway, I hope that helps you get better gas mileage.
