I just got my 05 STi---in the manual it says it needs 93 for best performance--the highest I have been able to find is 92---granted, I haven't looked hard, but every station I have hit has not had anything higher. I imagine it will be fine, but it could probably be better on 93? Has anyone seen a station around the midway area that has anything higher? Or anywhere else? What do the rest of you sube lovers do for gas? Thanks.
Go to wisconson!! 93 everyhwere!! BTW try and search. Search is your best friend!! http://www.mnsubaru.com/forums/showthread.php?t=10118&highlight=octane+locations
hmmm... yeah thanks for that search thing...I suppose I never thought of that. lots of info on that other thread. seems like 93 used to be more common. I remember seeing it fairly often.
Semi-related question.... I am going to get tuned tomorrow and I want to get tuned on 91 oct gas so that I can get outside the cities and still fill up at the rural gas stations. Do you guys know of any decent 91 oct gas down by RS Motors in Burnsville? I have a station on valley view road in EP that I am going to get 91oct from, but it would be nice to top it off before the tune.
I like 92 non-oxy at the Tressel Stop on Hwy 3 & 149, for those of us around Eagan/IGH. It's spendy though, usually 50 cents over standard.
the 92 non-oxy I get in the cities here are the same price as Premium. Cty RD B and N. Dale, Randolph and Snelling ave, 35E and Wheellock pkwy, Stillwater and Century??.
BP92 at all times. I wont fill the car with anything else. Unless it's Shell...but there aren't any stations nearby.
K-United Gas and Foods we get the same gas BP gets. I use our 92 all the time and have not run into any problems.
Got a Shell and a BP right blocks away from my house. I like to run V-power most of the time otherwise BP Non-oxy 92 or reg 92, non-oxy ain't cheap.
BP Amoco @ SE corner of 394/Louisiana has 92oct. Shell (?) location on Wayzata Blvd in Wayzata has non-oxy 93 and 100oct and 110oct.
yeah i paid 3.29 for my non oxy this morn...but in reality its only a buck or two extra each fill up whoopydoo
FYI, there's only like 3 sources of gas in the twin cities. All of them are extremely high quality and stations all source from them -- addative packages are added at the station. Quality depends only on volume and tank quality. Any station that cares enough to provide 93 (they can make a few more pennies over 92 or 91) also cares enough to take care of thier tank. If they sell 93, I don't give a crap who's sign is in front of the station. For 91 or 92, its BP, Shell, etc only For 93, there's a Holiday on lake next to kolwalski's and a Shell at 36th and Chicago. None are that close, but the shell's closer than you think. There's also a generic station on Snelling near 94. it used to sell 93 when it was a Holiday, don't know anymore.
That one is definitly 93. Filled up there a couple weeks ago. It is oxy though. Never found a source of non-oxy 93 here.
If you want 100 Octane the no-name station on the northwest corner of Rockford and 169 (on the frontage road) has Unleaded 100 for ~$6/gal. Other than that Both the BPs at Bass Lake and 494, and Plymouth Blvd and Rockford Road carry non-oxy 92.
If you were tuned on 92 with oxy then continue to use it. I saw a performance decrease when running 92 non oxy after being tuned for 92 with oxy. Like most have mentioned, logs showed my ride liking BP92 the best.
Actually their additives are added at the pump stations for the tankers. Each of the major brands have their stuff added as it hits the truck. Or did last time I was in a fuel truck filling in Roseville.
I wouldn't fill your tank with 100 octane, but if you are a stickler, you can put in a few gallons then top off the tank with 92. It is a simple averaging equation to figure out the octane of your tank. (92 x number of gallons) + (100 x number of gallons) / 16 (total gallons in tank, actually 15.9, but for the sake of easy math, 16 works)
So, to make 93 octane: 13 gallons of 92 = 1196 and 3 gallons of 100 = 300 Add those together and you have 1496 Then divide that by 16 and you get 93.5 which would be the average octane of your tank.
I'm not sure why everyone is obsessed with the non-oxy gas. Ethanol is a knock inhibitor. You'll be able to run more timing with e10 gas then with non-oxy. The only plus I can think of with non-oxy gas is better gas mileage...
Most of the gas for all the stations in this area come from the two local refineries one Hwy 52 in Rosemount, the other off of Hwy 62 in St. Paul Park. The tankers get each brand's additives splashed in them and then dump the fuel in the station's tanks. So the only difference between gas at one station and the next is the additives and the physical tank at the station. Besides the different octanes of course... The drivers pull into the pump stations either at the refineries or in Roseville, select the brand/type of fuel and pump away. I have done several drive alongs with the fuel trucks since I use to work on the truck's onboard computers.
Good info. So all the gas is the same, but the additives are different. The additives make a large difference in the way the gas performs. So the question becomes- who has the best additive package? My money goes to Shell or BP, I have found virtually no difference between them. With other types of gas I have seen large differences. The scary ones are when you get one good tank from a station, and then get a few really bad tanks from the same station.
