I just went to Atlanta and i got 33.3 mpg. I went to the game and shut my car off three times there and two times back. I also had the windows down. And at times I even had the AC on high. The funny thing is i had luggage and three people in the car. I just wanted to tell everyone my miracle lol

 

was this a dream???

 

No i thought it was but it really happened. Its a bone stock 2004 mt. I drove 15 over the speed limit as well. I know it will never happen again but it was great while it lasted

 

happened to me once too when i drove to LA here in cali

 

ha ha i just noticed i meant to put 30.3 ha ha but still i was impressed

 

well you still broke the 30mpg mark!

 

ive never heard of mpgs even closee to that on a 8.....is this a joke??

 

are you serious? WOW! I hope I get that when I move down to Nashville on thursday

 

Impressive. But kinda unbelievable.

 

Not going to discount the possibility - the key is very few start ups , constant speed and mild acceleration .

 

how did you calculate your mpg?

 

+1..

 

If you've ever tried to fill up the 8's tank all the way to the brim (not a good idea, BTW), you realize that there is a huge margin of error in filling the tank, at least 1 gallon. Calculating mileage on a single tank of gas is just not very accurate. I personally have gotten highway mileage in the 26-28 mpg range and someone else reported 29 mpg on an automatic. I'd like to believe 30 is possible, but if you can't reproduce it on multiple tanks, especially back-to-back tanks, don't take it seriously.

 

I calculated it when i took my miles I have drove and then divided by the gallons i put in my car to fill it back up. I went 304 miles and and got 10.04 gallons. I know i didnt go till empty but it was the last gas station for a while of 411 and i had to **** ha ha. I know it was a miracle and it will never happen again though. Also i had it on cruise control most the way. A total fluke bc i normally get like 22 to 23 mpg but that is with some city travel.

 

congrats while it lasted! lol

 

Ok since it is hard to believe that a RX8 can get 30+ mpg. Maybe the pump shut off early and you thought that you fo your car filled. Lets say the pump stopped at 10 gallons but you really needed 12 gallons to fill your car. 304/12= 25.33 mpg. Now i would believe that number

 

Maybe your math skills are lacking a little bit

 

No miracle, just a lack of a standardized test.

 

Is it not possible it was downhill the entire way to Atlanta?

 

that's pretty awesome if it's true. I just did a short road trip and got 24 and thought that was great

 

what kind of oil are you using??

 

I saw No way....
My old Cobalt barely got over 32 MPG highway there is NO way an 8 can do it.

I've seen about 22-23 out of my 8 and that was 5 over the speed limit for 100% highway driving using cruise and no AC... Can't get better settings than that.

 

^ id say its possible when i took my 8 to florida on spring break i averaged 29 mpg all highway on 2 tanks and 28+ on the way back 2 tanks too so 30 could happen ...

 

If the drive was on a down slope I could see getting better than average with the added weight but 30mpg seems unrealistic.

 

Ha. I've taken my g/f's newish Malibu (big cobalt basically) on a few highway trips and haven't gotten below 37 mpg.
