When I bought my car from the dealer told me to put 89 octane in it. I just recently figured out that were supose to use 92. Ive had no problems, but im going to swap over to 92. can i just go and fill up with 92 next time or do i need to run it till its almost empty and drain it and start over. Sorry Im not the gas expert.

Your dealer = dumbass
It specifically says in the manual and on the car that it requires premium fuel. That means 91 octane or more. How long have you had your car? I would definitely recommend that you switch over to 91 or greater, 92 in your case.

when I first bought my car they didnt have a chance to wash it until the next weekend so I brought it back. First I found out they filled it w/ 89 octane then...i got home & noticed my rims looked ******... I took it back & they discovered that they used chemicals to clean the rims (no no) & it ****** up the finish. So they then had to purchase brand new rims for me 
Ive had my car for over a year and a half. So its ok to just go fill up even though i still have 89 in it. Sorry for the dumb questions. Im just curious. Oh by the way what will this help or prevent, besides the apparent loss of power from a lower octane fuel.

higher octane helps prevent detonation which can lead to blown engines.
it allows more assurance that you will burn all (more) of the fuel at the predisposed time when the engine expects it, which prevents bad things from happening
p.s. you can just fill up with higher grade from here on out (no matter what's in your tank now...).

Many car ECUs (cars designed for higher octane) will do stuff like pull timing on lower octane fuels. So the car will run fine, but you lose power.
I don't think the MSP's ECU is smart enough to do that, though, it probably just would ping.

Most cars with "good" software will pull timing when you put in lower than recommended octane fuel. The EVOs do that I know for sure. That would explain the poor performance. The MSP should do the same, but I wouldn't know since I'm new to the scene.
e10 is crappy ethanol addatives, which make your car run like ass. They use is in NY and it wasn't very nice to any car I had.

I was recently forced to run 89 in my car last weekend. There werent any gas stations around that had 93 available. They had the pumps but no damn gas. It runs the same IMO and UI havent experienced any pinging

i believe most fuels in michigan use e10. I've never had any problems. with the MSP or my previous Talon which was ran at 17 psi boost. If you read the millions of stickers it will say that the gas may contain or does contain.... and so forth.
and yea any car with a computer controlled igntion like the DSM 's or MSP's will have knock sensor that will pull timing if you put crap gas in. If you are running above stock boost then you def. want to run high grade gas cuz it wont pull timing fast enough for you to save the motor.

I buy mistake put in a full tank of 87 nothing happened u have to remember these cars where masproduced turbo cars I would like to hope they would have taken such things into account
If you live anywhere around Indiana, the odds were you got ethenol in your gas. I'm the maintenance supervisor for Gladieux processing and we make/re-refine 90% of the gas used in the area. Ethenal is used as an octane booster, and yes 10% is the mix. The real octane booster thought is a chemical called MMT by the Afton chemical company. That is the most widely used octane booster in the industry.
