What fuel do you run in your EcoBoost pickup? (not HO)

My octane is bigger than your octane :)

I contend, the consumer will not recognize a difference in octane. Can you measure a difference on the dyno... maybe. But it's not like you're going to get you 100 or 50 or even 20hp gain without a tuner, and those are very difficult to install on new ECU's.

You guys are too brand loyal to see anything but your own ideas.
If your comparing 2 trucks it seems like a basic criteria is to have both trucks at full factory specs. with factory recommendations. Doing anything less compromises the comparison, plain and simple you may not agree but those are my thoughts. I don't need to own the truck to have that opinion because those thoughts apply to any comparison. WE could be talking Dodge, Chevy or Ford.
Secondly I agreed with another comment that the load being pulled in the comparison did not have a large frontal area vs. a typical RV load. The poster (not me) went on to question the millage results. Do I need to own a certain truck to make that observation?
But I agree with you. You are entitled to draw any conclusion you like, If you feel my comments are off base and not valid because I don't own the truck in question, you are certainly entitled to your opinion.

Correct, this is a public forum where we can all post our ideas and thoughts which is why you have to take some posts with a grain of salt because they have no facts or experience behind them. Some also have bias ill intent behind them which generally be spotted very quickly when one chooses to start using immature names such as "Ego Boost", "Duracrap", or "Powerjoke" which generally takes all validity out of their post.

I guess it just boils down to which is more valid. The word of someone who doesn't own or has never had any long term towing experience with the engine in question and likes to call it an "Ego Boost" versus actual owners who do have hundreds of miles of experience towing with said engine. Hmmm, which one do you think knows more about the topic and that we should take more seriously?

They did.


Then someone would say, but I don't want best results I prefer worse results when towing.

It is more like excellent is good enough. Those here that have actually tried it reported the results were not impressed with the improvement. The one guy that actually reported using 91 octane while towing said: " cannot tell you the difference."


Ford could write and entire bible on the effects of premium fuel but the average consumer would not understand all the technicalities, so they simply state use premium fuel when towing. Leaving us to proclaim premium is not necessary,ignore the manual.

As you stated a few lines up, they said "for best results". Ford never said that it is necessary except for the HO version. So now we have a Chevy diesel owner making up stuff that he would like to see in the manual for Ford gas engine owners. As I said earlier, somebody trying to justify not buying an EcoBoost. Now, please go share you expertise with Chevy diesel owners and leave us idiots to our stupid ways and quit taking over threads about Fords just to complain. I am happier that way.

Unfortunately for you this is a public forum. Where you can post and share your ideas With everyone by the same token they respond with their thoughts as well. This is not the "Yes Man" forum where everyone just agrees with what you have to say.
Believe it or not you are not always right and again neither am I.
But we can always learn from others. Dissenting,different opinions are not always evil or ill intentioned.
What does Chevy have to do with Anything? Because you see it in my signature? I never mentioned Chevy in our discussion of Ford trucks.
If you must know I own several trucks, some gas some diesel, some Chevy some Ford.
I don't believe I took over your thread nor do I believe I called you an idiot. I did think differently than you on the subject , but is that a crime? Must we all agree with the original posters comments?
Maybe it's a sign of the times, where too often discussions turn into my way or the highway.
If it makes you feel better to single me out, I'm fine with it. But I'm not the one that originally mentioned the Ford manual. I don't have a F-150 manual and have no idea what is says. Another poster mentioned the manual.I'm also not the only one that questioned some of the logic.
Nevertheless If you don't want to hear/read thoughts different than your own there is always the block button. A sure fire way to only get feedback that you like and fits your narrative.

This is exactly what the 2018 manual states.....

Your vehicle is designed to operate on
regular unleaded gasoline with a minimum

regular unleaded gasoline blended with a
maximum of 85% ethanol (E85).......

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 as well
as other conditions, for example when
towing a trailer.


It never states that premium is required when towing. It just stayes that it is recommended IF you want the best performance and it will be most noticable in heavy tow and/or in hot weather.

E-85 is not allowed in 3.5L Ecoboost. Im not sure about the 2.7L but I assume its not in it either.
Stock from Ford anyway.

I use 87 whether towing or not. I plan on being above 7000 ft a lot later this summer. I will continue to used 87 even at higher elevations.

The real engine gurus are those that know more than the manufacturer.
They know the owners manual is full of wrong statements that are to be ignored:S

As I said in the previous threads, it is not a matter of saying you know more than the manufacturer, but rather your perception of what the manufacturer is stating here. One may perceive that Ford is stating that you have to use premium fuel when towing while others percieve what the manual states is that you can use it if you want more power, but it is not necessary to engine longevity.

If you look at all the owners manual for Ford, theyvstate the same thing for all of their engines that use cam phasers and direct injection that can adjust time on the fly. Heck, they even state the same for engines they don't have direct injection like the 6.2L and I would bet that they would say the same for the new 7.3L gas engine.

You know we can debate every word to support our point. One referred to the process as learning, while another will dispute learning and proclaim it's just sampling to engage the correct parameters.

That is exactly what Ford states in their manuals. For best performance, premium is recommended. They never state anywhere that is is required when towing. They only state that you can use it if the best engine performance is wanted or needed.
