There are also other issues in the winter that makes your car worse on gas one being air is denser due to the cold which makes it cause more drag and friction when you drive, your optimal oil temp and other fluid temps need more time to get to optimal temps so more friction. Your tire pressure is lower, and gas historically is less efficient and has less power in the winter than summer due to different grades.Can you do a test of about 20miles on the highway on cruise? I believe that way we’d have a good baseline to give you our results. I think you should be at least 28mpg without a tune assuming you putting 93octane. I’m not familiar with cold weather/engine effect. When was the last time you check/changed plugs?
