The ECU will retard timing to prevent knock. Don't make a habit of it but the engine will be safe.

America, the land of liberty? Where in a few states the govt. think you are too dumb to pump your own gas, lovely.

No worries one tank will do you no harm.

In fact on my e46 M3 (2002) I used 3 tanks of regular fuel then one tank of super in-between, did this for years without any issues.

I wouldn't rip on the engine too much until you have used up the 87 and refill with 93.

Just my .02

I drove through NJ once and was really surprised that I couldn't fill my own tank.. Crazy place.

modern cars are smart enough to detune themselves with insufficient octane. You, I assume, bought a high performance driver's car because performance matters. That, and the sometimes lower quality of lower octane gas (not really an issue), should be enough of a reason to run 93 octane gas, when available.

Plus, as gas gets more expensive, teh $ price differance gets smaller and smaller since the grade price differance is usually fixed in $ not %.

What does the manual tell you to do?

Based on the question I'd be surprised if the owner's manual has been read.

What are the gas grades in non CA states? Ours goes 87, 89 and 91 and of course diesel where available. Every M3 in CA runs their lifetime with 91 and we know nothing better so it is the norm.

OBD II cars from 1996-present all have knock sensors. With a high compression ratio of 12.0:1, without knock sensors, there would be a lot of premature detonation in the cylinders because low octane fuel can't be compressed to those ratios without spontaneously igniting...however being a post 1996 car, the ECU will immediately retard the engine ignition timing. This is just a guess but it probably ignites the compressed fuel air mixture early so it doesn't do it automatically. Though I'm not sure how this works since you can't change how far the piston extends into the top of the stroke. Anyone care to chime in?

You can't fill your own gas tank in Jersey? In Texas, I'll let someone fill my tank when they pull my cold, dead fingers off of the the gas cap.............

You can fill it up with regular all you want with no problems.
Way too sensitive with this regular vs premium gas imo.

I think it is hilarious when people say things like "one tank is ok but I would not make a habit of it!"

By the logic you guys use than you should never be driving in the heat and severe humidity of summer either since your car is doing the same thing it is doing with lower octane gas, which is pulling timing and thus creating less power. If you do not care about having less hp or you drive pretty softly than there is not one problem running 87 your whole life and will do nothing to your engine.

Running 87 in 60 degree weather is probably better and you get less timing pulled than running 91 in 100 degree summer weather.

Now if you run 87 and floor the car a bunch than you might as well use 91 since you are giving up a bunch of power but as long as you do not care about the power it is totally fine to use it forever with NO damage to anything
