87 Octane in an EcoBoost with GPF

[710-oil-614]

I tried 91 and noticed no difference when driving . my ecoboost is a 23 so I think no gross particle filter, curious if thats why?

It can take a few tanks to adjust but unless you were really under throttle you aren't going to notice the gains but they are significant and real.

Who knows, it would be a guess. But there must be a reason why the 2025 2.0L EcoBoost is really a total redesigned engine. Think the law suit and the checkered past of this engine, particularly between 2012 and 2019 had something to do with such an up date. In any event, each owner should feel free to choose what that believe to be best practices for the care of their truck. For me ,here in AZ, I will be using 91 octane.

Why should I trust Ford to always do the right thing; I don't live in a CARB state and I got a GPF anyway when they were having trouble supplying them for CARB states.

I guess I got lucky since I got my truck a month ago without a GPF and I live in a CARB state.

That’s all I’ve been doing since I bought it new in September…..premium unleaded to keep valves and other components clean. Runs quiet and smooth in any mode.

Exactly

Yep

I dont race or drive aggressive so yeah, probably wouldn't notice a difference.

My other vehicle is a hemi ram with an aftermarket exhaust....the first time i started my wife's maverick i was laughing, thought it sounded like a sewing machine! I think part of the reason for the redesign was the noise from the direct injection.

This is key. You will only see a difference at wide open throttle, at less than that you can just push the pedal more. It's fairly certain that WOT is among the the worst things you can do to an engine.

This is not correct at all. The power is available throughout the band and well before wide open throttle, nor is going WOT the worst thing you can do to an engine.

So its my opinion then using 91 octane is a waste of money. We have owned our maverick almost 3 years and have never used wide open throttle once.

When using 87 octane in the 2.0L EcoBoost the ECU retards timing to reduce engine knock. This results, among other things, in more unburned fuel being exhausted from the engine; thus causing the GPF to work harder. Not a good thing. I was planning to use 91 octane for other reasons; but since I am very concerned about having a GPF, and I do lots of city driving; for sure I will use 91 octane in my new Maverick Ecoboost.

What is your source for 87 octane causing more unburned fuel being exhausted? Wouldn't this unburned fuel damage a vehicles catalytic converter?

My 2023 EcoBoost doesn't have a GPF so is my cat in danger of being damaged by me using 87 octane?

Your money your choice, I am down with that

It was based upon the research that I have done on line. Do your research, and make your decisions accordingly. As I have said many times your money, your choice.

Did some research and I don't see anything that says 87 octane caused more unburned fuel to occur. And modern engines like the ones found in the Maverick are designed to handle both 87 and 91 octane gas.

Before electric computerized ignition was widely used, this knocking commonly occurred and could cause significant engine damage. Most modern engines have sensors to detect knocking. When detected, the computer delays the initial spark, which causes the controlled combustion to take place at a point when compression is not at its highest point. Although this eliminates the knock, it can cause the engine to run less efficiently.

Timing is the precise moment a spark plug ignites air-fuel mixture in the combustion chamber. A car needing high-octane gas needs advanced ignition timing, where the spark is ignited way before the piston reaches top dead center. Cars that use low-octane gas needs delayed ignition timing, where the spark plug ignites closer to — but before — the piston reaches top dead center. A car's ECU sends a signal to the spark plug to ignite fuel at the precise moment the car requires, based on inputs from other sensors.

No,lol.ford would not allow this.
