What octane is everyone using on a daily basis? Also I have a gas station with 88 octane I think it’s 15% ethanol I sure it safe to use every once in a while but does anyone else use it?
COM, first, welcome to the forum.
That question has been asked here what seems like hundreds of times; a search for 'octane' will give U more info than you want to read.. FWIW, my opinion is that having to ask the question of what's the right gasoline to use with the 3L Ecoboost engine is caused by Ford not clearly stating what the engine was specified with, which they do for all or most other Ecoboost engines.
Also FWIW, I use and have used 91AKI, the highest we can easily find in AZ, in all-four of mine.. I 'create' that 91 by buying 87 and adding Boostane to it...I have MUCH Boostane in stock, one of many reasons my late, loving wife called me Mr. Excess.
