Default Oklahoma Gas stations

guys and gals,

need a little help here. I'm currently deployed, but coming home at the end of August. It will be the first time driving my Z in OK. I've been told by some people that no stations sell 93 octane. I did a little research in the Lawton, OK area and only found 92 in 1 station.

Can anyone do a little research for me and find me a good station in Lawton OK for a fill up spot please.

Also, if any fuel I buy has 10% ethanol in it, is that bad or does it matter?

Use pure gas(no ethanol) if you can find it.

question for you experts....

I live 1 hour away from any station that will sell 93* ethanol free gas. It's a shell station that sells it. Does shell sell any 50 gallon drums of 93* octane and deliver to homes?

let me know please

Seems to me the last thing you want is a 55 gal. drum of gasoline in your garage.

Is your z modded? If not I would not worry about the whole 91 vs 93 thing. Shouldn't make a difference performance wise and isn't worth the hassle to get the 93.

Now if it is modded with a tune (higher timing), higher comp heads, or boost that is a different story. I have been in this same situation for a long time now. To make up for the 91 octane I have been running 12oz of fuel additive called Torco Accelerator. People in California run it with good success on high horse power cars. I my self have not had a problem so far.

Also keep an eye on the walmart gas stations. One by me just added 93.

My Z06 is stock and I use 93 octane ethanol free gasoline, which is available locally to me. When I have to use 91, I can tell a difference in performance and when I have to use 91 with ethanol, I not only lose performance, I lose gas mileage.

GM requires a minimum of 91 octane in the Z06/ZR1 but recommends 93 octane be used. The car's AFR is calibrated for 100% gasoline and when you run E10, the AFR is not correct for the E10.

I pay an additional 10 cents a gallon for the ethanol free 93 octane over 91 octane(E10 or pure gas) and it's more then worth it.

Use the ethanol free 91 and when you have a chance to fill up with 93 ethanol free gas, do so.

Totally agree on the ethanol vs. non ethanol. I would say the performance gain in the "real world" is slim on 91 vs 93. At least slim enough it isn't worth looking for or getting a barrel for the garage.
