What if wrong gas put in?

Well leave it to the women!!!! wait, just playen. Yea, i let my mom take the car out, and she filled it up with "regular" gas... i think she put in the lowest possible!

it was at a lil above 1/4 tank and she filled it to 3/4.

I know this is not good... but is this gunna kill my car?

Im thinken im going to go fill the last 1/4 with Super+ at Moble or w/e! - - - - what should i do? or is it even that serious?

It is not going to cause a problem, the large manual that comes with the car explains that 87 octane will work, but 91 or higher is recommended for peak performance. Hope that helps.

It's nothing to panic about, unless it was REALLY bad gas.

From the owner's manual, page 4-2:

"You may use a regular unleaded fuel with Octane Rating from 87 to 90 (91 to 95 RON) but this will slightly reduce performance.

Fuel with rating lower than 87 octane (91 RON) could cause the emission control system to lose effectiveness. It could also cause engine knocking and serious engine damage"

Your RX-8 won't perform at its best, but there should be no permenant damage.

Unless you do quartermile runs, you will not notice a difference between 87 and 91 gas.

Someone here achieved a 14.5 s quartermile, turned out he had used 100 Octane gas. I guess that's where it matters, only with the clock you'll measure a _TINY_ difference.

Do you think your dealer filled it with 91 gas?
My dealership doesn't even have 91 gas ..

...some people have tested better with 87 octane gas, and a lot of the old schoolers will be using nothing but.

dont' sweat it, and save yourself a few bucks if you're just gonna cruise around.

I know for a FACT the dealer I bought it from fills up all of their cars at ARCO...nothing against ARCO, but I personally prefer Shell or Chevron, with 76 as a final resort...

yeah, I think ARCO is the worst gas. It's cheapest for a reason.
To me, ARCO is in the same league of Rotten Robbie and other no-names. In my Firebird, I always got 15% less mpg with this gas.
Since it is only 10% cheaper, clearly a bad deal :-)

You would think that someone who is smart enough to come up with the money for a Viper would be smart enough to read the owner's manual as to what fuels to use...

I don't think you should worry...I mix gas all the time. In the city I always use 93 octane (about 1.50+ - 1.60+ per gallon), from various gas stations. And when I'm out in the sticks on the weekends, I use 87 octane because the only gas stations there ream you hard on gas (1.70+ - 1.80+ per gallon). From my own experience, I've found I can still push the card pretty hard with 87 octane without worry (up to about 8000 RPMs), but I've never redlined it with 87, and I don't plan to. Oh, how I love the music she makes at 8000+ RPM...sounds like a turbine about to rip out of the car.

I've used 87 with no problem - have even hit the red line a number of times without any problem. I did notice an extra "kick" when I put in some '93 the other day. I'll have to see what the resline feels like now!

No...we had 92 up until about 2 years ago...Then it went down to 91. Was not a pleasant realization since I used to race with nitrous...wasn't the best times in my life.

The gas we have here is like...2.00 - 2.10 for 91 octane. 1.70 - 1.80 for 87 octane.
