2020 F-150 XLT 3.5L Ecoboost SCREW 4x4
Do it! I tuned my 3.5 eco at around 3500 miles on 93 octane. I'm at just over 19k miles and not one issue and getting better mpg's too. I do change oil every 3k with Penzoil Ultra Platinum. And I upgraded plugs at 15K. I run a MPT tune and it really makes every drive fun.Last night for the first time I filled the truck up with 93 from Shell. I hope its not in my head but the truck feels stronger. It's bone stock and on 87 it runs very well. So now that I have 93 in it I guess its intercooler and tune time! Somebody please talk me out of it until my warranty is up. LOL
I am amazed at the power 213 cubic inches can produce. Forced induction or not.
