What octane rating do you use?

Tpeterson · 10-29-2016, 12:55 PM

It's the only 93 octane available in the Twin Cities as well. I use it because it's recommended in the owners manual and my Dinantronics is tuned for that octane rating. I was going to try Shell until I saw it was only 91 octane.

Beartato · 10-29-2016, 02:06 PM

I've only got up to 91 here which is convenient 'cuz that's what the car needs.

F22_Will · 10-29-2016, 02:35 PM

I use 4 gals of E85 & 9.7 Of Shell 93 , im guessing thats like 95-96 octane

Shayan55 · 10-31-2016, 11:32 AM

91, im in ca and we dont have much better lol

delvec03 · 11-01-2016, 05:22 AM

89 here...am I a bad car owner? Hah zero problems so far. no knocking. starts every time. runs till I turn it off. going well so far 27k miles.

should I worry? everyone else is running higher. I know manual says 89 min. maybe I'm just saving $$ ? jk

RacerDad · 11-01-2016, 05:55 AM

I use 92 or 93 depending on which gas station I go to. I have not seen 91 available locally. Our choices are usually 87, 89, and 92/93.

Rayscott · 11-01-2016, 08:53 AM

91 here for the 228, I have used 89 in my X3 for 5 years with no issues.

I would not consider you a bad owner. The manual says the car requires 89. There should be no damage or warrany issues if you use 89.

krhodes1 · 11-03-2016, 10:32 PM

It just happens that the station that sells 93 has the cheapest premium gas in town by ~$.20/gal. All the rest are 91. Either is fine, but I wouldn't use less than 91 in this car.

Spydeputy · 11-04-2016, 06:51 AM

93 Octane in Maryland.

91 is perfectly fine, as that's what recommended by BMW. Esso's 93 includes ethanol (if that matters to you)

BentZero · 11-04-2016, 10:31 AM

Shell 93

Anthony235 · 11-04-2016, 11:01 AM

Other
91 + E85 = e35
Sometimes VP 101 too.

forumlurker221 · 11-04-2016, 05:34 PM

91 in CA. Any higher and it is too far for regular fillups.

Spydeputy · 11-05-2016, 05:26 AM

You really use track fuel as your daily gasoline?

89 is the minimum recommended octane with a few caveats. I generally use 93 and leave it at that. I don't think 91 is available in Virginia.

wjjkoevoets · 11-07-2016, 04:37 PM

Normally I always filled the car up with RON95, but since I'll be getting a tune soon I've switched to RON98 (BP Ultimate). It's easy to come by over here, but it's just stupidly expensive ($6.25 a gallon

Sunoco is the only station that I've know to have 91 on the east coast!

42395_skyline · 11-20-2016, 02:08 PM

93 Top Tier only

The car states that minimum is 91.

P2 · 11-21-2016, 08:51 AM

From my manual

Kolyan2k · 11-21-2016, 09:30 AM

So to sum it up, out of 127 people we got 5 cheap bastards who put 89 in the car ))
