Top end Cleaning, 26 mpg!
I did a top end cleaning on my engine and did a fuel injection cleaning.

I used MOC products, Fuel-Injector Cleaning, and I believe it was called Carbon Deposit Cleaning. I also got Throttle-body & Air-intake Cleaner but cant use it, because we have Throttle by wire and it will screw up the TPS

just take the throttle body off, unplug it, and spray both sides of the butterfly

Usally around 28-30mpg when cruise is set at 60mph. Long trips are supposed to be long for enjoyment... and she looks bess at that speed
