Not saying that I will but these premium fill ups are cutting into my mod $.

I used BP/Amoco premium. Is that the best?

Also, I am not sure if we are really getting premium anyway because I notice some hesitation and sputtering yesterday.

Nothing will happen if you run it once or twice, but you'll experience some knocking and possibly other things after a while if you run on a grade not reco-ed by the manual. There are always exceptions, but I wouldn't recommend running on anything other than 91+.

Sorry to jack the thread,but NYLexSC what the heck is that in your avatar?

it looks like some guy gets his head cut off and a kid going krazy afterwords.

hahaha, i had to downgrade the colors to get it under 20kb, but look closely, they are two lego characters (almost) and one puts a floppy disk into the disk drive, then the disk ejects and cuts his head off, so his friend goes crazy. I thought it was funny.

Sorry guys but running regular unleaded in our SC's does absolutely nothing to the engine. The computer's advanced knock sensors adjusts the timing to prevent any knocks. The only thing you'll notice is about a 5hp decrease. Most people won't notice that anyway. Search and you'll find a grip of threads on this exact subject.

Yup, i'm broke right now run regular. Just retards the timing and dosen't have much pickup before 3 and lacks it's performance potential . When I run premium (not often) I LOVE IT, feels like a whole different car. Oh well getting a new job soon, always premium + octane booster.

i would much rather be running the Premium but with the cost right now and some other expenses + the daily commute to work, regular will serve it's purpose for the time being!

I hate how my car runs with 87 in the tank, I did that once by complete mistake (talking and getting gas at the same time) and will never do it again. My car is already slow from jump and using 87 only makes it more evident. I also notice that 91 lasts longer than 87 does.

If you're in a pinch get 89, but not 87 unless you can deal with the sluggishness and decreased performance. I can't.

...and Idrewfelix, can you tell what's happening in MY avatar? That's me getting SLIZZARD after work at the bar! ha ha ha ha!

I can vouch for that, I want to put premium in but for 2.679 on only 89 octane, I just can't afford it, i've decided to go with mid-grade to try and make up for not going premium. Also, i've only had the SC three months and it was owned by a buisness beforehand, so it's never seen premium except for once (when the prices were down) and possibly when it left the dealer the first time.
My Dad even fills his 530i with regular (im ashamed) *hangs head in shame*
