The city gas mileage on my 2024 1958 trim had been 17 mpg. This was disappointing as less than the EPA rating 21, but the highway mileage was 27 mgp which is better than the EPA rating...
Around 5000 miles, I put a bottle of Liquid-Moly DIJectron injector cleaner in the gas tank before a fill-up. The city mileage improved to 22 mpg and highway remains 27 mpg. The improvement has been stable for several hundred miles with various different testings. Hoping it stays improved above EPA rating for both city and highway and this information may be used to others as this forum has been helpful to me.

The engine had received a 5000 mile synthetic oil change, and also one at 800 after the break-in period.
