Mike B Posted April 29, 2018 Share Posted April 29, 2018 Reading my manual for our 2018 Fusion with the 2.0 Ecoboost. It says it's designed to run on 87 octane. It also says to run premium during the hot times of the year. Is it really necessary to run premium during the hot summer? Here in Oklahoma, our temps will run anywhere from the mid 90's to low 100's. 0 Quote Link to comment Share on other sites More sharing options...
NCEcoBoost Posted April 30, 2018 Share Posted April 30, 2018 It says the exact same thing for my 1.5T. I've been using 89 this winter, which I intend to keep using unless I run into issues. Mine's a '17 that I got last September. Try the same and see. Here in Charlotte, we generally run in the 90s from June to September but it can vary. 0 Quote Link to comment Share on other sites More sharing options...
Mike B Posted April 30, 2018 Author Share Posted April 30, 2018 Thanks for the input. I will give this a try and see how it runs in the summer. 0 Quote Link to comment Share on other sites More sharing options...
jerry12 Posted December 26, 2018 Share Posted December 26, 2018 I run 93 octane in both of my 1.5 EcoBoost Fusions because of the vales carbon issues. 0 Quote Link to comment Share on other sites More sharing options...
Waldo Posted December 27, 2018 Share Posted December 27, 2018 The EcoBoost is direct injected, so the fuel never runs over the valve. Therefore running a higher octane fuel won't help clean any carbon off the valves - that's why it's an issue in the first place. 2 Quote Link to comment Share on other sites More sharing options...

Wolfie1 Posted March 7, 2019 Share Posted March 7, 2019 Mine is a 2013 ecoboost 2L. First I used 87. Then went back to 93. Engine much quieter, no downshift uphill. I don't mind the 20cents. My tank doesn't hold that much and I do get 1.8 avg mpg n town and 3 on hwy according to trip. I think a lot depends on how u drive. I don't get on mine, don't have to. Pass on two way Hwy easy w/o much more pressure enough 4 turbo kick n. 1 Quote Link to comment Share on other sites More sharing options...

Here in the Chicago area, premium is often 60-90 cents more than regular! 1 Quote Link to comment Share on other sites More sharing options...
bangster Posted March 8, 2019 Share Posted March 8, 2019 If premium is only .20 a gallon more (which used to be the norm, but is rare now, I think it is closer to .40 to .50 or more locally for me), seat of the pants and mileage increases make it worth it. I had a premium recommended car (97 Mark VIII) that got much better mileage and drivability with premium, my cost difference of .30 a gallon was where I would not go with premium. but: 20 mpg at 2.00 a gallon for 87 (10 cents a mile) 22 mpg at 2.20 a gallon for 91/93 (10 cents a mile) Seems like a wash, and I would run premium in this case! The HP and torque numbers you see for the 1.5, 1.6, 2.0 listed are using 93 octane. There are a variety of blurbs for different years, but generally for the GTDI engines (not the 2.5) Premium fuel will provide improved performance and is recommended for severe duty usage such as trailer tow. To be fair, with my 2017 Escape with the 1.5, they don't show the HP rating using 93 octane, but the owners manual does say that for increased performance, mainly hot conditions or towing, premium is recommended for all engines. 0 Quote Link to comment Share on other sites More sharing options...
