2014 2.0l 90,000+
I have noticed MPG slowly moving from low 30s to low 20s.
Mind you, I drive it like the Rally Racer it is.
I had read on these forums about the need to upside clean the valves.
I have used Seafoam a few times, 30,000 intervals. It helped, some.
I read more about GDI motors and the need to also clean/service the injectors, as the fineness of the mist/spray can affect fuel/cylinder burn and MPG.
A side note, we always use TopTier gas.
I've read good things about Royal Purple products.
I found a Royal Purple GDI injector cleaner.
MaxAtomizer is on the label.
It is 6oz bottle for 10-20gal fuel.
The first dose I doubled up.
Two bottles in the 14gal tank.
Then ran the tank to 1/8th mark.
Added One bottle to 10gal fillup.
The 3rd Royal Purple tank we had a scheduled oil change.
I did the Seafoam valve cleaner the sunday before monday oil change.
We are now 5 bottles into Royal Purple treatments.
MPG has noticable improved from low 20s to high 20s.
Hoping MPG continues to climb to previous low 30s with continued treatments.
I will also use the SeaFoam on the next (maybe couple) pre-oil changes.
Best price I could find $3.99, Summit Racing.

My MPG dips down to 22 with avg of 24. If I baby it or do a lot of HWY miles I get up to 30/32. Just hit 30k, 2019 2.0 Auto. I was going to have a mechanic do a "carbon cleaning service", but curious about these cleaners. I do run a bottle of Techron every oil change. When I know I'm going to be driving hard (mountain driving or weekend cruise) I run non-ethanol gas.
