93 Shell. Near the house, so it makes it easy.

I would never use that chevron fuel cleaner stuff. Most of the time it just gets everything loose and stuck in your injectors doing more harm than good.

I won't buy shell premium anymore. The main brands are ripping people off on premium. I buy Costco now.

Shell is one of the cheapest gas stations here, and with Stop & Shop discount points is the cheapest

Ripping people off? Please elaborate. I haven't heard about this before. I know it's not the cheapest brand out there, but for me it's by far the closest and most convenient top tier brand near my house. Costco isn't an option anywhere near me.

In the Chicago area and in Florida,the difference between premium and regular is 85 cents at all major brands. Costco is not only cheaper but the spread is less. Today the difference was 45 cents. Almost $6 for 12 gallons. There is also principle involved.

Spread here is 50c at Shell and 38c at Sunoco, but the premium difference is only 8c. With discount Shell usually comes out 2 to 12c cheaper per gallon then Sunoco which is one of the cheapest in the area

I looked up Costco and they are cheaper according to reported prices, by about 25-30c, but gas station is too far away

91. Apparently I can't find 93 in my city at all because of the elevation

Suburbs are always going to be cheaper then the city. I live in the suburbs. Here the difference between reg and mid is 30c. Then another 55c for premium. In the city,the spread is $1. Costco is 7 miles away. It's worth it. Sams is down the block,buts it's not top tier.

I remember when Reg gas was $1, Mid was $1.05, and Prem was $1.10. Now that Reg gas is $2.40.. What is the spread like 30+ cents between each grade? The one station by my office is like 45 cents between each grade. That's almost a buck difference between Reg and Prem.

It might be cheaper to use some octane booster.

My Costco is 23 miles away, Shell is almost around the block

been using 10g 92(premium) at Shell mixed with 32oz of Torco on weekends. Im guessing around 102 octane and car runs amazing. But during the week its just 92 from the base stations

[aelarson]

91 at Holiday stations in the Minneapolis suburbs.

[Gabbykat]

Very first tank of gas today and I used 91 at chevron. Just as I was fuelling, I saw the sign "may contain 10% ethanol".

I understand it is okay for warmer weather but I will check out Shell which is further away or use chevron 93.

We are recommended to only use 98 Octane here in Australia for the M235i. We have had some fuel issues recently and BMW suggested we move down to 95 Octane.

I seriously had no idea that it is so low in the US and Canada.

I use Shell 91 octane. I get gas points from our super market. Saved a $1.00/gal. on an almost empty tank.

Different Octane rating method. US + app 5 = Europe?Australia/... > US 93 is equal to Australian 98

I was under the impression that boosters added tenths of octane points, rather than full points. Read the attached link, for example. (see chart)

Interesting, I haven't used any additives in my fuel other than Torco Accelerator. FWIW tho I did not see them test Torco Accelarator and maybe because Torco claims they are not like the other octane boosters but rather a
"race rule concentrate" which could be why you get much better performance and higher octane number with them. Check it out, http://torcoracefuel.net/pro-accelerator.html

As the car requires 89 but recommends 91, I'm curious to know what octane others use in their cars. Does anyone run 89 on a regular basis?

I'm in NY so I use 93. Why would anyone use less than 91?

Because it's cheaper and most don't race/track their cars so they won't see or feel any benefit in using higher octane gas.

If one uses lower octane gas.. even 87, the odds are you'll never be able to tell, but can save more than a few pennies. The spread I'm seeing between Reg and Prem gas around me is 65 cents to a buck. From Mid to Prem, I'm seeing like 30 to 50 cents. About the only place that's reasonable around me is Costco.. where the spread from Reg to Prem is like 30 cents.

It's great to save money - I do it all the time, but I still question why someone who buys a car with sporting capabilities skimps on gas. So even with a 50 cent per gallon difference between regular and premium, that amounts to a savings of $250 per year. That $5 a week, or about 80 cents per day. This calculation assumes 12k miles per year at 24mpg. Your savings will vary.
