Octane Testing... Safe?

Forgive me if I missed a similar discussion and searched poorly.

I see a lot of talk about 91 octane vs 87 octane and am sort of curious to try it out first hand.

Gas being fairly cheap right now... I am not overly worried about MPGs. To be honest, I am not overly worried about performance gains either. I just want to see if I can feel a difference and what that feeling might be.

My driving is about 75% city/suburb streets and 25% highway. I'm typically happy with my mileage and performance, BUT... I have never compared it to another octane. I've only ever put 87 in any car I've owned (including 3 Ford Escapes over the years).

So anyway... my actual question... is it safe to switch octanes and switch back? Is there anything special I should do? I guess if I were just winging it, I'd run the fuel tank down to 1/8 full or something and then switch... then be sure to stick with the 91 through a couple fill-ups. If I switched back, I'd do the same 1/8 run down.

I'm driving a 2016 Escape Titanium 2.0 Ecoboost.

Advice and belittlement welcomed (lol). Thanks in advance.

No issues in switching octane and there has been a lot of discussions about this.

Thanks, I appreciate it. I figured there must be a lot... I just couldn't quite find them. Kept coming up with more threads about the pros and cons of them as opposed to the safety of switching between them.

That said, I thank you again.

What I meant was there is already a lot of discussion about people who have compared low and high octane with MPG and power. Also the owners manual already states that you can use low octane but higher octane will give you some more power and it is recommended when towing.

Yeah... I was almost not going to make my post but I had this nagging voice in my head that said, "What if there is some magical process involved in making the switch and you messed up your beloved Escape?" haha.

the vehicle learns the octane of the fuel in your tank by constantly testing the limits by adding timing, using feed back from the knock sensor.

this article explains how the ECU learns the octane.

it does it fairly quickly, so you can add whatever octane fuel (>87) you want into the tank, and the escape will almost instantly adjust.
