Repost, Important

I was sleepy at the gas station and didn't realize that I put too low an AKI rating in my car, but that was after I filled the tank....
IS this bad?
1998 e36m3 says a minimum of 91 AKI, I put in a full tank of 89 AKI.
I know that the knock sensors can compensate, but I can cause some sever engine damage if this AKI is too low.
Is this too low? Will I be okay? Should I and if so how would I drain the tank?
AHAHAHAHAH

I wouldn't sweat it. Absolutely no reason to drain tank. In about 50 miles or so, add some 91 octane and then again at half-full tank. You'll be fine w/no long term problems. Computers may adjust a bit making performance a little less than optimal (but you may not even notice it).

Worry about iraq or bush or something else...shouldn't lose sleep over this one time slip!

Sorry. Okay. Breathing a bit more easily now. Can you tell I'm a bit obsessive about my car? I wouldn't want to wreck it over something as "trivial" as gas.
Thanks for the comfort. I was about to die.

PS - I did notice a drop in performance.

No. But if you do, I suggest using a shotgun . All those little holes will drain it quicker than you think.

Keep driving it... but every chance you get... fill her up with some higher rated stuff.... till your entire tank is full with it...

I didn't see this post at when it was curretn but wouldn't it make sense to pour in a can of octane booster you see next to the fuel treatment stuff?

[ws6firebirdta00]

i wouldnt put that octane booster crap in the tank its no good IMO. spark knock is no good to the motor but it wont kill it. the knock sensors pull timing which is why you notice a power loss. but in hot days im sure your car will spark knock even with 91 in there. 89 is not much lower and definately nothing to worry about, but dont get on it too much, WOT detonation is no good

[thekid]

just don't go around flooring it while the 89 in still in there. with mild to modrate throttle there will be no damage.

I've often wondered about this, because I've reached for Regular (89 aki) before realizing that wasn't the premium button, and stopping.

[RexKing86]

you'll be fine

[Furious]

like said above your gonna be fine, if your very anal about this type of stuff, you could add an octane booster or do what was said above and fill the tank with premium at every 1/4 tank to dilute it

It's all out of the tank by now (Seeing that I refill every 2-3 days from my daily commute). Now I'm just REALLY really careful about gas. People must think I'm weird at the gas stations, staring at the pump for so long.

Pics of you staring deeply at a gas pump or ban.

Damn...I have a 318i 4 cyl 138 HP car and I use 93 (or 94/95 octane-when i can get it) all the time.

And you are putting 89 in an M3!!!! - Brave soul you are!

Actually last weekend I was pumping my 93 oct into my 4 banger at Mobile and a brand new waxed midnight black 2005 645i pulls up and this thugged out guy gets out and pulls the 89 octane pump and begins pumping 89 Octane into his car!!!!

I was like about to run over to him and say "WTF!!!!!!! DUDE....NOOOOOOO!"

But my girlfriend joked that maybe 91 and 93 was to pricey for him....I felt so bad for that 645i being malnourished like that...I shouldda car jacked the prick!

Well I know my 318i eats well all the time!!!
