Unleaded 88?

[Dogcmp6]

In the owners manual it says to run at least 87 octane fuel, and not to use any fuel with an ethanol content greater than 15%, with that being said, is it safe to run Unleaded 88 in our trucks? (this is a different fuel from E85. E85 is 85 percent ethanol , unleaded 88 is 15 percent ethanol) It sounds like its safe according to the owners manual, but I am curious how the 2.0 would handle it

15% has had problems with modern engines in testing.

You can use it, but your FE will drop by ~10%.

Ethanol requires about 30% more fuel than gasoline. If 15% is ethanol, you will lose roughly 4.5% mpg, not 10%.

My real-world results in TC engines has always been closer to 10%.

I have been burning E-15 88 Kwiktrip fuel in my 2014 Ford Fusion 1.5L turbo for over 100K.
I currently have 170K on it. I get 33 mpg on the highway at 72 mph. EPA window sticker mileage states 36 highway 28 combined. My new Maverick 2.0 L will only have E-15 88 in the tank (whenever it arrives).

It's placebo. BSFC is math, it doesn't lie. Unless manufacturers are purposely making the car run even more rich than stoich with higher ethanol fuels, then there is another reason you are losing that much.

With these engines, we are talking 1mpg from the differences we are talking about. The quality of gas from 1 company to another could cause that.

I don't like using gas that uses ethanol to hit a "standard" octane rating, because what they are doing is using much more shitty gasoline, and using the octane of ethanol to compensate. To each their own of course, but if I'm using ethanol blends, it's for performance, meaning mixing 93oct with E85 to get roughly 100oct for cheap.

Speaking of Kwiktrip, are you guys getting hit with a glazer shortage too?

I have tested in the 8 cars I have owned since 1993 when E-10 first became available & every one was 10%-15% loss in fuel economy, I try to avoid E-10 whenever possible, but if the non ethanol fuel is more than 15% in price, its a wash.
