pump in 9.175 gallons of regular gas
As title! I think I am not thinking at the moment I fill up my gas tank just now. I accidentally press regular instead of premium. What should I do? Or just leave it and remember it next time?

You did what??!?!
Thats gonna hurt your car BIG TIME! You have put you car in grave danger by adding regular. This could result in your engine blowing up!!

I had a diesel car that a gas station attendant filled with regular one time. That WAS a big problem. Had to remove the tank to drain & flush the fuel system before refilling it. At least we got the fuel for free after all that, but at close to 3 hrs it has to be the longest fillup ever. 
spc, I thought the cap was labelled already, but if not, I guess you could put one on. Or just paint a big $ on the inside of the filler door.

Also (if premium is 93 Octane in your area) consider refilling your car with premium after burning about 4-5 gallons of the regular that you just put in rather than waiting for a full refill. This will get your average octane up to close to where it needs to be sooner rather than later.

Don't worry, spc. One tank of regular won't kill your engine. Follow rb1's advice and be careful next time!

How about a shot of that tank additive stuff that boosts octane? 
Won't that effectively raise the octane for this tank of gas and get spc out of the woods for this tank while we argue knock sensors?

I gotta be very careful next time! Understand it is not good at least for the performance. Maybe I should not rev my engine too high with this regular tank (actually it is a little more than half) of gas. As rb1 said, I think I will put premium after 4-5 gallons of usage to compensate it.

As far as the knock sensor detecting knocks, the ECU will pick the knocks way before you can actually hear it and it will retard timing accordingly.

After reading JTso reply, it make me feel more confident by just leave it alone (rather than maybe doing more harm by adding wrong stuff in there) and easy with the driving and put more premium after around 100 miles or so. Thank you all!

You save $2.00 a fill...
It may cost you down the road. I wish we had the 93 octane here in KC like you have in St. L.

That said, I run the car exclusively on 91 octane. The extra dollars are not worth the loss in performance, as far as I am concerned.

After having driven my truck on a recent roadtrip, I then switched cars and "automatically" filled up the TSX tank (about 15 gallons) with... 87 octane. Oops! I didn't realize this of course, until I started to note the transaction in my log book.
I ended up running the tank until the low fuel light glowed. I never detected any kind of pinging or knocking, even when pushing the car.
Oh well, the only thing I did notice differently is that in 2nd gear (AT) you can noticeably feel the VTEC stronger than before. Of course, that might be because below 6000 rpm, there's not as much power as there should be!

p/s: I have every transactions of all the cars I ever owned and use MS Excel to make a chart and count the average and some statistic stuff. So far, my TSX average 26 mpg.

New model cars are much more rugged than people give them credit for. Some people (i.e. every female member of my family) drive for thousands of miles with the check engine light on, or go 20k miles with no oil changes.

You could also say "if you can't afford to wash and wax your car every week [to protect the paint], then you can't afford the TSX" which is just about as ridiculous as arguing whether 87, 89, or 91 octane is going to have long-lasting reliability and fiscally responsible impacts.

mmm,, where can i find the info about a/f mix ration of out tsx? how do you know it's 6-7% richer.. ??

I agree with this 100%. Don't buy a car that you can't keep up with payments, insurance, service, etc...

also in Canada except Sunoco Ultra 94, the more premium we pump into our TSX, the more MMT TSX will have to take.. it's bad, bad bad, probably worse then 87 octan... anyone know how much a Mg coated O2 sensor cost?
if i have time, i will mix 94 with 87!!!! hehehehehe and dealer say TSX is rated with 87? ??

doods...just get premium gas at costco or sam's club...it's usually the same price as regular unleaded at local gas stations, plus it gives me a reason to go to the warehouses and get all the free samples ...i've used costco/sam's club gas mainly the past 3 years and have had no probs with my lude or the tsx(yet)...

The scan tool is also very useful to determine the actual intake air temp (IAT), RPM, condition of O2 sensors, throttle position (TPS), coolant temp, MAP, ignition timing advance, and many others, as well as the ability to read/clear CEL. It's similar to the type dealer uses to troubleshoot problems.
You can also use the PC based scan tool, which is also very helpful. The advantage of a PC based tool is it allows you to datalog all sensor readings and store on the hard drive for analysis. There is also a Pocket PC or Palm version as well. HTH.

thanks for the link, good read!!! thanks for info!! i don't have the tool, and probably won't buy one... too $$$,
look like you have access to the tool ? i am courious to know if TSX runs rich at all RPM or just above some point? does rich A/F happens all the time?(i think most engine will run rich when engine is cold/start up and propably above 2/3 of all useful rpm... )
thanks !!
