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.
