DFW: Who Still Sells 91–93 Octane Ethanol‑Free Local Stations only (NOT 90, NOT Murphy’s)

Posted by Key-Musician-9441@reddit | Dallas | View on Reddit | 35 comments

Hello, I’m looking for Premium 91–93 octane ethanol‑free gasoline in the Dallas/Fort Worth area.

To be clear:

NOT 90 octane
NOT Murphy’s blue pump
NOT “ethanol‑free 87/89/90”
Only 91, 92, or 93 octane without ethanol

The usual online station finders have not been accurate including(pure gas) and I’ve already checked the common stations people usually recommend.

If you’ve actually bought 91–93 ethanol‑free in DFW recently, which station was it?

Thank you!

https://www.pure-gas.org/

They even list the octane for each station.

That site doesn’t show anything in DFW that’s 91, 92, or 93. That’s why I was trying to find an actual person who has successfully pumped higher‑octane fuel in our area. The map just confirms there’s nothing above 90 around here, so I’m looking for real‑world experience instead of the same listings.

That list is all user reported by people intentionally listing specifics. That's your best source of data, far better than polling random residents.

You're saying dfw, which even "proper" is a wide spread. You may do better on a specific locale. For example, if you're in fort worth, the Kent Kwik in Crowley has 91, and it's not that far south. A lot closer than the Anna location somebody mentioned.

I don't recall if it's the specific kind you want but the gas station at Dalrock and 30 has a big sign advertising ethanol-free

Thanks. I checked the map and tried calling both stations on that corner. The Shell doesn’t pick up and doesn’t have voicemail, and the Valero number routes to VP Racing Fuels’ headquarters—they said they don’t have a direct number for that location. Looks like I’ll have to drive over there and verify in person.

[-]

StrLord_Who@reddit

I can let you know later today what they have exactly as I'll be over there. (It's the Valero not the shell)

[-]

Key-Musician-9441@reddit (OP)

I really appreciate that, thank you. That’s very kind of you. I’ll be crossing my fingers.

[-]

StrLord_Who@reddit

Bad news. Only options at the ethanol-free pump are 87 and diesel. Sorry!

[-]

Key-Musician-9441@reddit (OP)

No problem, I appreciate you checking! If I ever find one I'll update the post.

Harlows outside of Anna on 121.

Key-Musician-9441@reddit (OP)

Thanks, but wow — that place is insanely far out. This is my daily‑driver car, so I need something actually in DFW, not way out there. I’m trying to find a real solution for a specific reason, which I can’t say on here. I just need to know if anyone has actually pumped 91–93 anywhere in the metro lately.

[-]

JoyrideIllusion@reddit

I kind of take offense to the "actually DFW" snide remark. It takes the same amount of time to get there from Downtown Dallas as it does to get to NW Fort Worth - which is literally in the name of the region you requested.

If your problem is so touchy, I would think any solution would be a "real" solution.

Sorry for trying to help.

In my experience it is not available aside from like at Motorsports Ranch in Cresson.

Historically, ethanol-free was not available at all in populated areas but it's relatively recently become available for powersports and lawnmowers and stuff.

If you go on the Murphy USA site, you can filter for ethanol free premium and this is what it looks like

Wow, that’s really far but it does make sense. I was told the issue starts at the terminals, the big fuel depots where tanker trucks fill up. Supposedly none of the Dallas or Fort Worth terminals carry anything higher than 90 octane, so the trucks can’t deliver what the terminals don’t stock. That’s why the higher‑octane stuff is so hard to find around here.

[-]

M990MG4@reddit

It's an emissions-related requirement for metro/populated areas to have "oxygenated" fuel (ethanol, previously much more toxic additives like MTBE) to reduce smog... so it's not that they don't stock it, it's that it's not allowed for general car use.

Recently the midgrade ethanol-free has been become available for lawnmower/generator gas but it is generally about $1 more/gallon so most people opt out. I was rusty on the history but found this with background info:

Very interesting, thanks for the info.

I also came here to say that if you're willing to go out to Cresson, the gas station on the Motorsports Ranch has what you're looking for. They have delicious barbecue as well.

Not really the answer you’re looking for, but just in case you haven’t already considered it: if you can find ethanol-free 89, an octane booster might be able to get you where you want to be.

[-]

Key-Musician-9441@reddit (OP)

Thanks for the suggestion. Unfortunately that won’t work for my setup. I’ve got a European twin‑turbo sports car, so running the Murphy’s 90 ethanol‑free and trying to boost it up isn’t really an option. I’m hoping someone here actually knows of a station in DFW that pumps real 91–93, because so far I haven’t found one.

Dale_Gurnhardt@reddit

I feel like it'd be Sunoco if anything

[-]

Key-Musician-9441@reddit (OP)

Thanks, I already tried their fuel search, and the highest‑octane option they show near me is the 94 with 10% ethanol on New York Ave in Arlington.

Why NOT Murphys?

[-]

Key-Musician-9441@reddit (OP)

I was told Murphy’s only carries ethanol‑free Unleaded 90, and I need 91, 92, or 93 for my setup. But if you know of a Murphy’s anywhere in DFW that actually has a 91‑plus ethanol‑free pump, drop the location because I’d definitely use it.

Murphy's isn't a Top Tier designated fuel carrier. Means they don't guarantee additives and detergents that help keep fuel systems "clean" or reduce carbon buildup. This is different from octane ratings. I drive a 5.7 liter Tundra. The engine is a workhorse that only requires 87 octane. But I definitely notice engine performance/reaction time when using QT or Exxon (both Top Tier fuel carriers) vs Murphy's.

Note that in engines that are designed to run on 87, running higher octanes fuels that have slower burn speeds actually decreases gas mileage and increases sooting on the valves.

[-]

M990MG4@reddit

In my experience, sometimes.it is beneficial to run midgrade. Like in August when it is 110° and the car is heat soaked and you are stuck in gridlock... My car pulls a lot of timing and reva slowly and reluctantly. But on 89 it feels a lot more like its normal self on 87.

I only bump it up to 89 in July and August

Not an answer to your problem, but you can rule it out apparently:

https://vpracingfuels.com/pages/wimm

My husband buys 110 octane leaded from them, and did a search on their product line - looks like none is ethanol free.

[-]

noncongruent@reddit

Ethanol is a great way to boost octane, and it has the benefit of absorbing residual water in a fuel system so keeps the fuel system cleaner. Downside is that older engines, think before fuel injection became a thing, i.e. carbs, often have seals that ethanol can damage over time. All newer engines use seal materials that are completely compatible with ethanol.

[-]

CatteNappe@reddit

He buys the high octane for what is definitely an older engine, carburetor and all; but it really needs to be leaded gas to run properly

[-]

noncongruent@reddit

Leaded gasoline was mainly to lubricate the exhaust valve seats since back then they machine the valve seats into as-cast iron heads. Without the lead you get seat erosion, especially in performance engines which produce hotter exhaust. When lead was banned car makers started using induction hardening for the valve seat area in castings which eliminated the erosion problem. Very few of those engines are in daily driver status now, and any engine built or rebuilt since then will have gone with either hardened seats or steel seat inserts. AFAIK the only internal combustion engines still in regular use that require leaded gas are in aviation.

Have you tried https://www.pure-gas.org/TX ?

JoyfulCor313@reddit

I don’t know the octane bc I don’t buy it, but Buccee’s of all places has had ethanol-free for mowers, tractors, etc.

Worth a call.

Forward-Act6688@reddit

Been looking for this too for my bike - most places around here only carry the lower octane stuff without ethanol or they stopped carrying it completely
