That was the stuff I used in europe as it was the highest octane available and for a turbo car you want to use the highest ocane... when my car comes back stateside I plan to use 93 octane here.... but what is the euro 100 octane equal to? (I know it's a different formula there)

[AndrewAZ]

Using higher octane for turbo cars is only necessary if you have some major tuning done. Just use the recommended gas which is what 92 or above for BMW?

Found this on the first page of a Google search using keywords "european octane rating":

In most countries (including all of Europe and Australia) the "headline" octane that would be shown on the pump is the RON, but in the United States and some other countries the headline number is the average of the RON and the MON, sometimes called the Anti-Knock Index (AKI), Road Octane Number (RdON), Pump Octane Number (PON), or (R+M)/2. Because of the 8 to 10 point difference noted above, this means that the octane in the United States will be about 4 to 5 points lower than the same fuel elsewhere: 87 octane fuel, the "regular" gasoline in the US and Canada, would be 91-92 in Europe. However most European pumps deliver 95 (RON) as "regular", equivalent to 90-91 US (R+M)/2,and even deliver 98. (ron)

Yes I'll use 93 octane....but wanted to find out what the euro 100 octane translates to....

[KEVIN88GT]

lawdude so 100 octane meant I was using 96 or 95 octane.... is that accurate? What cars would need that in europe?m 95% of the cars on the road there have sub 2 liter power plants....I dont get it

According to the Koenigsegg CCX page on Wikipedia, 110 RON (Euro) is 95 octane U.S. Assuming that's correct, I'm guessing 100 RON is 93 octane in the U.S.

Around here, the Shell premium gasoline is 93 octane, so that should be about the same.

Here in southern California, I usually only see up to 91 octane for Premium.

I saw 93 oct in cali before but not any from a brand name gas. I think Shell only has 91 here Cali

Theres one gas station in town here that offers 100 octane, they call it "racing" gas. Costs 6.99 a gallon. I think ill fill up my new M with that for her first meal.

100 RON(european) is equivalent to about 93/94 Octane...

93 & 94 Octane can be found in almost any eastern seaboard & midwest state. California and other certain irrelevent far west states have 91 Octane pump gasoline. Yes, there are "specialty" gas station that have racing fuel and other grades, but "premium is 92/93 Octane almost anywhere you go in the united states.

As opposed to irrelevent (sp) mid-west states?

In WA, almost all the pumps have 87/89/92 available. Places like Costco just have 87/92, skipping 89 altogether. To find anything higher than 92 you typically have to source racing gas (which is pretty hard to come by.)

Stick with 91/92 Top Tier Gas and you should be GTG.

Most "racing" gas is leaded since race cars dont have cats. So make sure its unleaded. The station down the road from me sells 100 "racing" octane but its leaded. I know a few people with classic cars that use it and I will say it smells good when burnt lol.

At the pump here the conversion is posted 98RON = 93 octane.

California enviornmental law prevents gas with highe than 91 octane to be sold in california. doesn't depend on the brand, 91 is the highest here.
