Good Gawd, Aseras, do you only drive downhill? Did they forget to install one of your rotors? Is yours a diesel? Are you sure you have an RX-8? LOL
but seriously I'm just blown away. Have no idea how to explain that in light of mine and other's experience.

 

i'm in florida so it's flat.. that's about it. lots of traffic lots of stop and go. i drove it 50 miles to work today, took a bunch of guys out to wrok who HAD to ride in it and of course i had to get on it a little bit and so far it's sucked down a bit less than a 1/4 tank of the 93 i put in the last night. so that's about 70 miles to 1/4 tank.. i'll report back in.

 

Aseras, you are quickly becoming the person that everybody will love to hate.

 

Seriously dude, better check to see if you are defaulted to kilometers instead of miles. That just can't be.

 

Seriously. I get 330 miles out of 2 tanks of gas.

 

it's in miles..

and it feels MUCH slower on the 93 than it did on the 87.. but then again I've had 3-4 people at a time in it twice today when i got on the gas a bit.

 

ok got home did some errands, down to just under 1/2 tank @ 174 miles. power still feels lacking.

 

makes sense...you dont notice it unless you drive insane amout of miles or kms...i drive between 12K-17K KMS a yr and i barely notice the gas crunch.. but i can somewhat feel for the person driving over 60K km a yr...but then again they shouldnt have purchased this car... because if you driving 60K a year the 1st thing on your list is gas mileage..

 

you mean it feels slower on the 87...93 is for higher performance generally...

 

no the 87 felt WAY better.

 

Don't want to start a new thread but I find this interesting so I'll bring it up here. When the car was brand new my first measured mpg was 9.02. I **** you not. This was all in-town, in super-cold weather. But a recent measurement (highway, warm weather) yielded 24.3 mpg, How's that for a variation? In-town mpg is a lot better than it was -- 17-18. Octane is 91.

 

Well, temperature has a lot to do with how good your gas mileage is. For one, you have to let the car warm up for longer. The 8 runs extremely rich during the warm up, especially in cold weather. My gas mileage goes waaay up in the summer.

Also, how are you measuring your MPG? Formula should be (miles driven/gallons filled in tank). Make sure you take the reading from the pump.

I'm usually around 19.5mpg mostly highway.

 

You're just living in a parallel universe. That's the only way to explain it. Can I live there also? I'm looking for a job that pays three times what I make with one fifth the work.

 

you should get into management then....

 

V, that 9.02, was that for the whole tank? I ask because, even now, 16,000 miles later, my 8 still guzzles gas a lot more gas in the first 1/4 tank than at any other point (either that or it fluctuates severely). If you only did a calculation based on a partial use of the gas tank, then that may explain the discrepancy. I can't stress enough, though, that even with the simple [miles driven/gallons filled] formula, you won't get highly accurate numbers. At best, you'll get numbers only for comparison with your other calculations, but even then, apparently so many factors play into how quickly or slowly that dial drops that I question the reliability of the figures.

 

welp I'm at 280 miles and still 1/4 tank left... power seems better now.. but it took a while. It snuck up on my yesterday i gunned it pulling out into a turn ( lots of traffic i was never gonna get out ) and the car took off smoking the tires a bit before TC caught up.

i dunno i'm used to driving my honda for gas milage, and generally i try to keep rpms for city driving as close to 2k as possible... if i'm crusing a steady speed and not accelerating I'll drop it into 6th if it's over 35 mph, other wise 5th or 4th depending on the speed. I still rev it to 6k or so through 1st and second then straight to the highest gear for crusing.

 

Aseras, I don't know about the MT, but with the AT at least it's not necessarily good to drop below 3000 rpms with the 8. There have been several threads popping up about the engine jerking with the AT 8 in its highest gear at around 40mph. For city driving, especially with the MT and how the ports work, just be sure to shift below 3750 rpms, as that is when the extra ports open up (or so I have read here).

 

It was for about 3/4 tank and based on miles driven and gallons consumed (actually converted from kilometers and liters but mpg has more meaning for me for some reason). I'm sure it was a reasonably accurate number. Fortunately it's never been that bad since and in fact as I said earlier, is quite respectable now. I'm not complaining.

 

Interesting. I like hearing different driving styles to try. I'll give this one a shot after this current tank of gas to see if it helps me.

I usually get around 16mpg mixed driving. Though the last tank I got relatively close to 17mpg even when pushing the car a bit more.

 

Good stuff--As long as you're happy with it. Mileage should improve as the engine ages, so perhaps that may be the cuplrit. Just to set the record straight, though, I never said you were complaining PS. Love the avatar :D

 

what's the lowest you can go in a MT without messing it up, i'm gunna be filling up today and going to try to see the best mileage i can get for this tank.

 

I have noticed if you do a lot of cranking the car up that is when the gas mileage goes downhill fast, if you were to crank the car one time and drive all over town without cutting it off and then do the samething but stop at different places during the same amount of time it uses gas like crazy then, must be something to do with cranking this engine.

 

Brice, sorry to say, bud, but I think that's how most all engines go :D

Navybeard, wish I could answer your question intelligently, but I drive an AT so I have no idea. My guess would be to keep it above 2000 rpm.

 

Well i put a full tank of gas in today and i am going to keep it below 4k rmps and mostly around 2500 rmps on 93 oct. so i'll tell you how it goes. If i get better then my best which is like 18 mpg then it works! hehe

 

Navybeardbb, are you asking how low of RPMs you can go? or how low on the gas tank?

I know for the gas tank when the light come on, I have 10 liters left which translates into 60kms (assuming the crappy consumption to be conservative).

I tried the cruising below 3000rpm and I tell you, it gave me an extra 30km or so but REALLY boring to drive. Pintos and Suzuki Aerio's were beating me off the line. I don't feel it's worth squeezing the extra little bit of mileage.
