My 93 Octane Experiment! 2.0L EcoBoost Maverick

[Snox801]

Yeah it's more rhetorical. I have a VW with DI and I haven't had an issue but I only have 37,000 mi on it. Christ you must drive a lot! Not saying that worrying about either of those issues would be enough to make me not buy it. I just know with 100% certainty neither of those things are issues with the hybrid.
You actually looked inside the combustion chamber or just the intake? I always assumed that carbon build up is specifically in the combustion chamber or the intake valve side because there's no gas washing over it? I would say my main reason I wish they made the hybrid in that drivetrain is just because most of my driving at this point is suburban with a decent bit of stop and go and that's the exact kind of driving where the hybrids mileage would be higher in the EB would be lower. I imagine if I did a lot more highway wheeling than I wouldn't think about it as much.
I guess it's just comes down to more power, better ride and now if I get a new one a lower price with the EB but worse mileage. The only real thing going for the hybrid in my mind is the mileage. I guess I'll drive them both and see what strikes me fancy

Correct on both I drive a ton. So I get to test a lot of things.
I have only taken off the intake as the back of the valves are what is gonna cause the issues. The combustion chamber will be fine as that carbon will be burned off or can be cleaned with fuel cleaners like amsoil, or crc. Heck even shell 93 has a ton of cleaning detergents in it. So you will be fine

Well, mathematically, it is 92 as I put in a full tank of 93 on two gallons of 89. Still, didn't see any difference.

I know octane can make a difference. My now decommissioned Saturn Vue would absolutely struggle unless I put at least 91 in it. And I suspect the Maverick will do the same after it crosses the 150,000 mile mark. But with only 4,400 miles on it, this tank of 93 does not appear to be making much of a difference that I can tell. And at $13 more per tank, not sure it is worth it.

But I'm also camping at the tallest point in Alabama next weekend. I'll be able to tell if the truck is a little more responsive than the last time.

The difference will mostly be 60-100% throttle.

The system can react instantly when pulling back timing and boost due to knock / low fuel octane. It has to.

But when it's relearning higher octane, it adds timing and high rpm boost much more conservatively. Like I said, a full tank or two. Your post I quoted seemed like you put in the 93 and expected instant results then came here to tell us we are wrong about the engine benefitting from premium fuel.

Value is a different conversation. Even if you do perceive the difference you probably won't see enough value to keep paying the 75 cents a gallon extra.

I switched over to 93 octane top tier gasoline, I have gained 3 miles per gallon and power is improved.

Nah, I think it speaks to my lack of refinement. You all are talking about the sweet notes in the wine when they all taste the same to me.

I just assumed the vibration was due to the lane detection sensors. Thanks for all the input!

There’s that too, but only when you drift out of marked lanes. You can test that function by intentionally changing lanes without using turn signals. Using turn signal cancels the function

That mimics my experience as well, except a bit too early to zero in on an exact mpg gain but judging the instant mpg screen on the productivity screen it seems to have improved.

The most pleasant aspect of this was wifey driving my truck not knowing I had put 93 in with about 120 miles of driving and remarking to me that the truck had "noticeably" more power and what did I do to it? No placebo effect there.

Another interesting aspect in all this is the fact that throughout this thread there are many varied responses to running 91/93 octane gas in our EB's. I enjoy reading people and find it all interesting. Maybe the factory ECU tunes vary according to MY or build date blocks or as I tend to suspect, different perceptions of the same issue. The sky looks bluer to some than to others yet we are all looking at the same sky.

I understand nobody likes paying more for gas and I realize my vote doesn't count much because I don't have one yet. But I think paying the extra for at least 91. If it gets you a noticeable power increase and a slight increase in mileage to offset, some of the cost is easily worth it. I guess it would depend on how many miles you drive. I don't put on that many so maybe it's a different story for others.

I have always run premium in all of my boosted or modified vehicles. Motors just tend to do better and last longer in my experience with better fuel.

I have come to the exact same conclusion.

Sport mode will solve your issue. Start truck, dial up D, press mode switch 5 times, you are golden and problem solved. Yes, you must do each time you start vehicle. If highway cruising, 2 button pushes get ya back to normal drive mode and lower rpm with better fuel economy.

Interesting. I've always run 87 octane, and every time I use sport mode it seems to cruise at way too many RPMs...

Well imagine me driving 380k miles in my 3.5 ecoboost and pulling a trailer 25 percent of the time. All in 5 years running nothing but 93. Lol

Wasn’t that long ago it was a must.

True.
I don't really understand not running premium in the EB. If you want to save money on fuel get the hybrid. If you want to tow why would you use regular fuel?
