Can you get a higher octane other than 91 in the US. How about using an octane booster to add to the fuel?
Any thoughts? |

We have 92 here in Hawaii. I've seen 94 at Sunco in certain states.
We also have 100 Cool Blue at special 76 Stations. I've tried 100 octane in my M3 and I really didn't notice any benefit. Unless your ECU is tuned for high octane gas (100 and above), your car will not benefit from it. |

My buddy had a 5.0 mustang, and he always used to buy these little bottles from kragen.. i think they were like boosters or something? He'd add them in his tank to get more power.. dont know if it really worked?

what's the problem?????
the car's designed to run on 91, you won't get any extra HP by running anything higher than that so why on earth would you want to??? I'm sure you could find some 110 octane race gas for $7 a gallon but the car wouldn't perform any better. Just buy your 91 and enjoy the car. 93 is available in lots of states though, no performance gain is to be had though |

98 octane here in Australia. I understand the E90s are tuned for 98 octane. If you do use a lower grade of fuel, the ecu adjusts the timing resulting in a power reduction, just like the current E46s, unlike my previous 320i E36 that had to use premuim fuel otherwise engine damage would result according to the BMW literature.

I have not used anything but Costco gas in any vehicle I have had for years...no problems and my engines run great. Plus they sell for cheap, sometimes at a loss to stay lower than the rest (used to be a Costco manager if you wonder why I say that). |

I can't say for sure if it was Costco gas, but I'll continue to use it since it's almost $0.25 cheaper than any other station in my market. For the cars I own, I don't mind springing the extra money since I don't drive those cars so much. |

My usual station (reigional chain mini-mart type) has 93 octane which I religiously use and have never had any problems. Sunoco stations have 94 octane most everywhere. As previously stated, you won't necessarily get a performance boost, but it will keep your engine cleaner over the long run. The choice is how much $$ do you want to spend at the pump vs. the benefit.

At the same pump here... you can get - 87,88,89,91,93,100 - Then there's another one for race fuel, at 110. Of course, standard premium is $2.66gallon right now to... and the 100 is $7 a gallon. So... it's kinda like picking your poison. My wife and I both have to use premium though, which sucks donkey balls.

87, 89, 93 octane is generally available in the Houston area. The 93/89 delta is about $0.20 to $0.25 for the most part with 89 in between. I will probably use the 93 when my 325i comes in in August.

So the car calls for 91? I always put 93 in my e46.
