Wow.... Y'all are picky...
I go through a tank every 3-5 days (the 8 is my commuter car).
Never had any knocking issues whatsoever, running 87 (regular) unleaded from any of the following stations: Shell, Swifty, Thorton's, Speedway, Marathon, Kroger, and miscellaneous truck stops for longer trips... To be perfectly honest, ALL gas stations in this area are supplied by the same refinery (Marathon/Ashland Oil); only difference is what additive crap a particular station wants to put in it, and the ethanol ratio.
About the only thing I notice is, Speedway costs the most, has the most volatile upward price swings, and generally gets the worst fuel economy (17.5 verses my typical 19.2), but sometimes, the bingo fuel light is on, and it's my only choice.
I've always subscribed to the theory that unless you have an issue, run with the lowest octane your engine will drink, 'cause otherwise you're just throwing money away for a false sense of "peace". No thank you...
(My 2004 8 has 76,000 miles and counting; I've put approximately 32,000 miles on it since I bought it in August of '08.)

luckily, I have a Shell station just down the block from where I live. Pumped nothing but 91 Vpower since a month ago when I rescued my 8. Shell ftw lol

Hehe, I actually did a tank a day in the DC area in a 91 Geo Tracker right after high school, something like ~200 miles to the tank. Thing was a piece of crap, and drove a ton. Only pay for about 7,000 miles worth of gas a year now.

Shell V-Power. It's actually almost always the cheapest gas here. Even can compete with the Safeway and Costco gas prices.

i just had a good 30 minute drifting sessions, and the needle hasn't moved. with v-power. v-power it is for me. i also heard you should just use 1 company repeatedly. and for the best mpg thing. i think shifting at 5 might be the best. shifting at 4k kills my mpg, and driving hard does nothing to the tank. rx8...you are weird...

Interesting reading. I used vpower (93) in my Impreza, but switched to Valero (93) when I got the RX8 to avoid the fuel additives (per Mazda recommendation). Not sure about the ethanol percentage on either here. 16-18 mpg on average.

I go between chevron or shell 93 octane and can't tell the difference. The only time I can actually feel any difference is when I stop by the ethanol free station and fill an empty tank with 93. There's is definitely better throttle response and the mileage seems to be better by anywhere from 2-5mpg.

Shell around here sucks!! Too high priced, makes no difference in the car. Exxon and Chevron are generally cheaper than Shell.
Besides my Exxon stock does better whem you buy their gas!!!!

Yea shell here kinda sucks. Generally 711, valero & diamond shamrock have the best gas here.
They have these shitty western gas stations that everyone lines up and goes to and its like always the cheapest in the city but I swear its like 5-10% water.

hmmmm....maybe this should be turned into a poll for noobies? along with oil?
what gas you use.
what oil you use.
so they have more confidence or peace of mind. and if not they can ask questions.

If memory serves, we do have them in Texas but they're not very common.
