With the Evo's thirst for higher octaine fuel perhaps we can get a list together of places to for buy fuel that meets the octaine spec.

I did some digging around the Minneapolis metro area and the best pump options I found were 92 octaine Shell and some 100 octaine "leaded formula". I have no idea if this stuff would be ok for my (upcomming) Evo.

 

Do NOT use leaded fuel! It will destroy the catalytic convertor, clogging your exhaust. Not to mention the joy it will create with O2 sensors...

Mobile is good, as is Citgo, but avoid Sunoco and Exxon, as their "clean burn fuel" has less energy despite the octane rating.

 

I have also been looking around the Nebraska area. The best I can find is 92 from Amoco.

What about fuel octane boosters? Like the 104+,,, is that ok to use , will it hurt the engine? And also what kind of octane would you get then if you used a bottle of it per tank?

 

In many places, the fuel isn't going to be all that different. Frequently there is one large wholesaler in the area that everyone purchases from. Off that base, they simply add their sometimes good additives (ex. Techron) to make their final product.

So basically, Mobil might be good somewhere but nothing special in another area.

 

silvrevo, we have a couple gas stations in Lincoln who sell 100 octance gas (unleaded). I'm pretty sure we can run that in our evos...I'll ask some car friends of mine and see if they know of any places in Omaha who sell 100 octane.

 

Ok, I've done a bit more digging on gasoline in Minnesota (and apparently some other midwest states); it looks kind of ugly.

First to 2Cool; don't worry I would not (and have never) run 100 octane low-lead gas in my unleaded sports cars. What I was curious about was the 100 octane "leaded formula" gas being pumped through what appeared to be an unleaded nozzle.

Now on to the bad news. Minnesota (and some of the surrounding states) by law requires minimum percentages of ethanol for both winter and summer gasoline formulas. This has kept at least one major distributor of high grade 93 octane gas from entering our market. With the required ethanol mixes, it's apparently very tough to produce good 93 octane gas economically. The few times I have seen 93 or 94 octane gas in Minnesota, the pump has had a “10% ethanol minimum” sticker on it; and I haven’t seen that stuff for sale in years. I've even been told our gas is worse than the stuff you guys in California get.

I don't want to start keeping drums of 100 octane unleaded racing fuel in my garage, so if you know of anything that might help out please let me know. Information that contradicts what I've heard is welcome too. Ultimately, I just want to be able to buy spec gas reliably.

 

I happen to live near a private airport.. they have Sunoco 114 octane which I use in my race car I'm also fairly certain its Unleaded fuel... There's also several gas stations in the area that sell Unleaded Cam2 (approx 101 octane if I remember correctly) I have yet to try anything but the 93 thats widely available. I was wondering the same thing about the octane boost products.. I know earlier products could damage your O2 sensor and possibly plug up your cat.. Whats the definitive answer?

 

?????? maybe someone should post an Octane boost thread?

I have seen people before measure out some and put it in their tank before filling up.

 

Mobil is owned by Exxon, so I doubt that there is much of a difference between their fuels.

Also, I would never run leaded fuel on a car with a cat. But you would be amazed at how long an O2 sensor (particularly Mitsu O2 sensors) can last while being fed leaded fuel a couple times a month. A couple gallons here or there doesn't do much to the O2 sensor.

 

Sunoco 114 is leaded.

 

In NC the majority of our gas station has 93 octane fuel and in my hometown there is one station that has a pump on the side of the building that has 102 octane but is high dollar.

 

i use nothing but sunoco 94 - i don't mind the addatives for a cleaner burning fuel

<~ support the environment

-> exxon/mobil (same company) - gets their gas from the middle east

 

i Know we can get 93 at most gas stations, and 94 at any of the Sunoco stations around here.100 unleaded is also available at most of the dragstrips.
