I may be wasting money but I use 93 octane here and I DD my car.

Yup, that's where I sit. 91 is the highest so that's what I use. It'd be 93 if we had any of that around in this state.

93 only, unless I'm in an area it's unavailable then the highest they have.

 

[theredmeadow]

86

as long as it's reasonably priced i'll use the 93.

Here in Florida we have 87, 91 and 93 and I have been using 87 from day one.

Is there any truth that with 93 octane my car will feel or actually be faster?

I have a ecoboost with no mechanical power mods as of yet.

The manual says 87 octane unless you are pulling a boat. Whey 93?

I run 93 but most of my driving is city. For long distances I would run 87.

 

[daltron]

91 with 91 tune.
