It is almost time for first fill up and would like your input (eb). 87 octane non ethanol or 93 octane with 10% ethanol ? Basically the same price.


Thanks

I use 87 non-ethanol. I've never tried 93 octane 10% ethanol - but I have run a tank of 87 & 89 10%. It may be my imagination, but the truck seems to drive better with non-ethanol. MPG are all over the place tank to tank - south Florida weather...the wind shifts and a head wind really kills any "economy". But I've averaged 17.5 lifetime using non-ethanol most of the time.

Doesn't matter. The dealer I can promise you filled up with E10 87. Whatever makes you happier. I run E10 87 in mine and have no issues.

You will get a tiny bit better MPG with non ethanol but the cost factor is normally equal to the tiny but less MPG but cheaper E10 87.

I have never ran anything higher than 87 octane. I cant justify the price for minimal gains.

87 is 87 regardless if it's ethanol or not. Ethanol will yield you a tiny less mpg but the price of it off sets it as I said before.

I've gotten better mileage with 93 octane. Enough to make it awash with the savings of 87.

I have always heard ethanol is bad for corrosion on turbo engines...no clue if it is true...main reason I asked.

What's the difference in power between 87/93 for the 3.5 EB? Just curious. My friends new ecoboost Escape states in the manual a 20 or 25hp difference and that's a 2.0L.
