yeah that's unfortunate, my friends have 1.5s and petal the metal all the time averaging a good 22-23 mpg.I have a 2022 Honda Accord EX-L (1.5t) and it has been getting poor gas mileage relative to others with the same vehicle/engine. With Driving in Drive with Eco Mode, the max mpg I have been able to achieve is about 21 mpg (with a light foot). I took it to the dealer and after running tests, they found nothing wrong and informed me that I should break it in with about 6k-8k miles, then if the problem is still persists, then bring it back. Currently I am at 1,200 miles. Any thoughts or suggestions?
