I don't know if Ford has mentioned this or if I've just missed it but have they said which fuel grade is required/recommended on the hybrid engine?

It's not premium right? I assume it's regular like the Escape hybrid?

Its basically the same powertrain as the Escape and I checked its user manual and online specs comparison and both say that while the ecoboost recommends 91+, the hybrid recommends 87+.

Edit: Darnon corrected that the footnote from the 40mpg hybrid announcement from Ford was referencing the Ecoboost alternative, not the hybrid. So all documentation says 87 for the hybrid! Thanks!

I have a 2020 Escape Hybrid. It says in the manual:
"Your vehicle is designed to operate on regular unleaded gasoline with a minimum pump (R+M)/2 octane rating of 87... For best overall vehicle and engine performance, premium fuel with an octane rating of 91 or higher is recommended. The performance gained by using premium fuel is most noticeable in hot weather."
I have noticed that when I use 91 octane, the engine starts with less of a shudder, runs smoother, and has better acceleration. Also, doing the same drive back and forth for work, I noticed a 3 to 4 mpg increase when I use 91 octane. That little mpg boost doesn't really offset the cost of the 91 octane, however, the other things combined have me feeling, at least in the summer weather, that the engine is running better because of it.

as for my current hybrid (Niro), the manual actually says premium is NOT recommended……not sure how Ford thinks about this. my hybrid is 4 yrs and I have never used premium and car drives great and have had no problems whatsoever

it would seem to me a car either requires unleaded or premium…not both.

The Escape uses the same manual for all engines. The tech sheet from Ford specifies only 87 octane (minimum) for the 2.5 hybrid.

The only harm in using higher than required octane will be to your pocketbook. Octane is basically rating how well it resists damaging inadvertent predetonation, and while its important to know what the minimum octane engine was actually tuned for, it is true that some people use higher octane under particular circumstances that can increase the chance for ping: very high mileage (carbon buildup), very hot temperatures, and unusually high loads. My truck is designed for mid-grade 89 octane for example but in the summer if towing and because I have over 150K miles on the engine I use 93. Likewise, you can often save yourself money and cause no harm whatsoever by taking a vehicle designed for 93 octane and running it on 87 octane if you're say just cruising cross country where you're just on cruise control where the engine isn't working hard and its getting plenty of cooling and ambient temps are normal or cool.

In any case, I'm satisfied seeing many different sources that the 2.5 hybrid is designed to operate on 87.

That was a great question though. My Prii (plural for Prius lol) are designed to run on regular 87 octane gas. When my son bought my 2008 from me, his girlfriend at the time convinced him that he should be using premium gas for a hybrid. I had to pull out the owner's manual to prove to him that - as always - he should listen to his mother.

Correct on both accounts :)
