Gas Price App

Hey Festers - new to the forum and tried searching for an answer but couldn't find one. I can tell fuel is a hot (read: annoying) topic here so apologies if you're exhausted.

Bought a '14 328i xDrive two weeks ago and, probably because I never looked for it before, I'm having a hell of a time finding AKI 91 fuel around me. I downloaded the Gas Buddy app but it only seems to show regular vs. plus vs. premium etc. but not actual AKI ratings at certain stations.

My question: has anyone found an app that includes the AKI ratings? Seems like most of the "Premiums" around me are all 93 so I could obviously mix 87/93 or 89/93 but would prefer to just use 91 assuming I can actually find it.

Thanks!
-B

I use 93 all of the time and don't look back. One station around me sells 92 for the same price that most of the other ones sell 93 for! 91 is the recommended minimum. not sure why you would try to mix fuel to lower to 91.

Not that I'm trying to pinch pennies, but I don't want to spend extra on 93 if there's no compelling benefit. That being said, if mixing 87/89 with 93 to get 91 was basically the same price as using 93, I would just use 93. But I can't compare unless I can actually track down 91 somewhere.

I would say mixing fuels to downgrade 93 to 91 average is pinching pennies.

Touche, you got me there

Maybe I'll just have to test it on my own to see how they compare given my driving style, commute, etc.

Just don't see the point in spending extra on option A if the benefit over option B doesn't outweigh the cost.

As always, please excuse my newbness

Want to run a quality gasoline AND save some money? Try this approach if there are COSTCO Wholesale Clubs WITH gas stations nearby or on your usual travel route. #1: their gasoline is Teir I ... $2: their usual prices are below typical local prices ... #3: get their Costco VISA card for an additional 4% rebate on your gas purchases (and rebates at other places VISA is accepted).

Gas Price App

I like the Gasbuddy app. I've found it really helpful in the past

gasbuddy is screwed up with advertisements and it's one of those stay away app now. Try "gas guru" it has no adv and run by yellow page.

Thanks luigi - I'm 1 of approx 15 people in the states who doesn't have a Costco membership but have seen others speak highly of the fuel there so might have to consider it

My $0.02, you're probably driving out of the way to get 91 octane and spending more in the process. Either get the costco or the shell card, if you are apprehensive about costco, and fill up the 93 that you can find.

You might be right. Looking at Gas Guru the Costco premium is running around $0.40-$0.50 cheaper than every other station. In some cases it's actually cheaper than some station's plus and premium.

OP - if your location info is accurate, you are in MD. You along with the majority of the East get 93, not 91. 91 is the minimum because there are parts of this country that do not get 93, at all.

The only place I know if that gets below 93 in the East is Wawa, they sell 92.

Additionally - every now and again I'll see a Citgo that has several different flavors of gas, 87, 89, 91, 93 and maybe a Shell every now and again that sells something bizarre in the mid-range.

Anyways - just put 93 in and stop wasting your time looking for 91 or trying to come up with a blend to hit 91 . You will also get more performance out of your car as the computer will adjust for the increased octane.

I thing that you will find that 91 is hard to find in your location. Sunoco tends to offer more choices than the normal 3, but most are 87 89 and 93 on the east coast.

There are plenty of threads about running lower octane fuels, so I won't rehash that here.

Thanks CK. Yes I'm around Baltimore/DC. I never paid close enough attention to what the stations around offered but I'm starting to see that you're right. Appreciate the insight!

Yep starting to find that out. Only reason I would ever go lower would be 89 if I was running on fumes and had no other option.

oh, the old hotdogs come in 10 and buns come in 8 package issue with Octane ratings in the US. You can look at the major gas producers' website to get their corresponding octane to product type and base off of it:

Exxon & Mobil: Regular 87; Plus or Special 89; Supreme or Super+ 91-93

Chevron: Regular 87; Plus 89; Supreme 91; Supreme Plus 94

Sunoco: Regular 87; Plus 89; Premium 91; Ultra 93

Shell: Regular 87; Plus 89; Premium 93

7-Eleven (Mobile): Regular 87; Special Unleaded 91; Extra 95; Supreme+ 98; Special E10 94

BP: Regular 91; E10 91; Premium 95; Ultimate 98

Wawa: Regular 87; Plus 89; Premium 92

Costco: Regular 87; Premium 91

But, why? 93 ain't going to hurt. Try Upside app for gas discount. The negative is that you have to select the grade of fuel you are looking for, so doesn't list all grades at a station.

It's hard to find 91 in the Northeast. Many Sunoco stations do have it, though. Most stations have 93, or some 92--just use that if you can't find a Sunoco.

Yup. If there's a convenient Costco with a gas station near you that you know you can almost always fill up at, join. I belong to a Sam's Club around the corner from me, and the gas discount pays for the membership--the discount is steeper on premium at mine.

There's a Costo that sells gas at Arundel Mills, if you ever get the membership and it's convenient for you.

Would probably use the one in Columbia more, but both are pretty close.

I am looking for some help from someone with a scientific background here. I don't think that mixing gasoline; one batch of 89 orctand and another of 93 octane produces gasoline with an octane of 91. I think you have a mixture of molecules of 89 octane and 93 octane, but they don't blend to produce some other gasoline.

I have long wondered if 91 octane was recommended for political and marketing purposes but that 93-94 was what the engine does best. I think that is the case because someone did dyno tests.

Therefore, just use 93. If you want to save a little money, pump 2/3 93 then pump 87. If both use the same nozzle, then pump 93 first so the 87 flushes all of it out of the pump hose.

Not true because stations mix regular and premium at the pump to get 89. There's not a separate tank.

If that 14 was a lease before you bought, I'll bet you at the very least there was plenty of 91 octane used on that vehicle. Maybe even some 87/89. I lease but I always use 93. I only put under 10,000 a year and I am not concerned about using 93. One time I wanted to see what it would feel like putting 91 octane in the tanks so I waited till 3 in the morning when I knew no one would be around to see. I put 2 gallons in and oooooh! I felt like such a bad guy.

I don't go out of my way to get COSTCO but I do fill up anytime I am at the store. Quality fuel at the best price in town. NC is pretty much an 87-89-93 state. Costco here is 87-93

Just run 89 and be done with it.. It's the minimum recommended by BMW and you probably can't tell a difference.
