REAL GAS - NO QTrip E10

[Robinson]

There's been a request for stations selling real gas. Unless it is marked on the pump you are buying ethanol blends which lower efficiency - 25-30% reduction in miles per gallon.

Definately have seen improvement since changing to the TEXACO at 21st and Harvard.

Check with the Fiesta Mart at 21st & Columbia.

Also check with Shell at the Promenade, 31st and Memorial.

Yes that is what I thought. They are dumping that garbage in all the fuels. I have found offten the sales clerk has no idea what is in their fuels. It drops your fuel mileage alot.

To add to the list, the convieniance store at S 126th and 31st advertises 100% gas

Mckay's at 31st and Jamestown.....

I believe the Flying "J" Truck Stop on 129th & I-44 runs with pure gasoline or they did.[xx(]

Does anyone know if there's anywhere in Tulsa you can fill up on 93 octane?  It's what my manual recommends but in Tulsa I can usually only find 91.  And great to know about the E10!  No way I'm putting that in my car ever again.

One thing you may want to try is to dump in a bottle of Octane booster. Big Lots and Dollar General sell octane booster bottles for about 99 cents. Places like Auto Zone have it too but they charge alot more.. You dump the bottle into your fuel tank when you fill up and it boosts up the octane of the fuel. It will be cheaper than filling up with 93 octane fuel. I don't know how good it is.

Oh I'm nowhere near worried enough to resort to octane booster.  91 should work fine, but I was wondering if there was anywhere that had 93.  I checked the 21st and Lewis Texaco, which is pretty top shelf, and it didn't, so I figured probably not anywhere.  

But again, great to know on the E10 when I'm passing through.

Anything out east other than Flying J?

I'm not opposed to it but I usually go to the QT at 161st and Admiral or 193rd and Admiral. There aren't too many more stations around the area so Flying J may indeed be the next closest.

Thanks!  And thank you, Robinson sir, for starting the thread![]

[inteller]

gawd, my car hasn't seen 93 in so long it would probably flip out.

thanks for starting this thread.  I figured the station at 21st/harvard did...but then their premium is also $3.40 a gal as of 4/10 [:O]

From what I have been told, in all new cars the octane matters alot for gas mileage. The higher the octane the better the fuel mileage. The reason is because the engine's timing is computer run and when you put in low octane fuel the engine's computer backs off the timing to avoid the "pinging" and as the timing is backed off mileage & engine power drop off. When you dump in high octane fuel the computer can advance the timing and the engine runs better and gets more miles per gallon. With older cars it's another story.

yes that is true to a point.  But higher octane doesnt dictate higher mpg. You can't make something out of nothing and if the energy content of the fuel is lower than before it won't matter.  E85 has an effective octane rating of 101+, but you don't get better gas mileage.  The main problem is these lazy car manufacturers use the "hillbilly tuneup" method of running higher compression/timing to get higher hp numbers.  The result of that is that premium is required for those cars a lot of times.   More intelligent engine management is making some of those cars quickly detime if they detect lower octane gas, but those are not the norm.

[sgrizzle]

Octane rating as it relates to what car uses what just means less likely to detonate. Many imports and some of the "high performance" cars require higher octane because they are using very high compression ratios like the Focus SVT at 10.2:1. That means you need gas willing to compress into an area 10% of it's original size without combusting(detonating/pinging.) You'll get a bit more bang out of that high compression but you're paying anywhere from 5c to 20c more a gallon due to the higher octane gas required.

The Fiesta Mart - 21st & Columbia went to E10.

Much better car performance by using the Texaco at 21st and Harvard. Three tanks have me convinced.

Any recs for mechanics?
