It not about cost it is about wondering how the different octanes will effect the car. Mostly mpg wise, because there are a lot of varied accounts from it works fine to only for emergencies and keep off boost. It is purely out of curiosity, and the inability to find a reliable source on the matter. Everyone seems to have their own opinion on this, but someone on here now has a new sti I was just wondering if they were going to look into it at all.
Even the difference between 91 and 93 I think would be interesting. Although I imagine it is negligible outside of computer when it comes to premiums, but that's just my guess.

I love your car!!!
I tried the 87 octane fuel on my Talon running my own maps with ECM Link management. It got to the point of making the car a total dog and defeated the purpose of owning it in the first place. So I gave up and now just run 91 octane fuel or better.
I built a a belly pan/parts and oil catcher also out of Lexan. But I can't run it during the summer month's. So I haven't recorded any stints with it yet. As soon as it cool's down i will put it back on.

Is it like entirely a thrown out idea because it's the sti version?
Now for an aside about the cts-V, how is rearward visibility? People always complain about how weird the back looks does it make a difference? I like the design of the rear, although, it does kind of make the car look stout. Which kind of goes with the trying to be muscle-y.

I can see everything pretty pretty well, I have a sedan. I think the visibility is an issue with the coupes and wagons.

I have an 02 wrx as I stated, I have a tactrix cable that I can run diagnostics on my pc and even with 93 I receive knock on occasion. But with wear and tear it's expected, I do need a service and tune to fix my a/f but 60% of it is poor octane. I've put 87 in when I had to and burned through it fast, stayed out of boost and would have more backfire during dfco mode.

Sure, I'll run maybe 1-2 gallons of 87 to test it out, but thats it!

Have you considered a gearing change? IIRC the STI has shorter 6th than the WRX's 5th. Though, Cobb Accessport would be the bigger bang for the buck, especially if you're willing to run ultra-lean (increases NOx emissions).

Yes I've considered a gear swap. Is putting a wrx 5th gear as my 6th gear possible? I'm just worried it might void my factory warranty.

No, nobody buys one of these things to hypermile, but when you're not busy scorching the pavement you might as well. That's how I got started.
Telling a Subaru forum that you hypermile can be very entertaining.

a lot of things tuners do to make their car faster can also apply to ecomodding (ie aero parts)
I absolutely agree, however convincing many of them is near impossible. To me, ecomodding is sport-driving in itself. Anyone can drive 90+ mph, however very few can maintain even 30+ mpg. Add in the cost of traffic tickets, insurance, and higher possibility of a traffic accident, and I'll take ecomodding over performance any day.
By the way, your grill block and foglight fills look GREAT!
