i just past 2000 miles and refilled my tank last night (14.2 gallons) i will report my ending milage to see IF there really is a change ...

PS:note that i am using 87 oct. which already proofed to me that there is no change in mileage range.

Spink9 I did not seeyour other post on the2nd page here sorry! I am pretty lazy and barely read the 2nd page of this. I didnt know someone wrote out exact directions for ggetting the mileage. I willtry your steps on my next fillups. But can youtell me if you arealso usually at aorund 60 miles by the time you reach the 3/4 full mark in your tanks?

Jerky, stop being so fixated about what it reads on the gauge. It has no meaning, it gives you incorrect and inconsistent results, and just leads to meaningless posts when we're trying to gather real data. Just forget it, ok? Now, go back and read where about 8 people tried to tell you how to CORRECTLY compute gas mileage. Use that technique, report your results, and forget all that stuff about the gauge. It is utterly meaningless for the purpose of this discussion.

Sorry if I'm being vague or ambiguous here...

Easy on JeRKy 8 Owner. He's from Florida & they don't know how to count down there...:p

It's real simple...

1) Fill the tank all the way & set your trip odometer to zero.

2) Drive it till you need more gas.

3) Fill the tank all the way. This time & from now on, record the miles from your trip odometer & then reset it to zero again. Also, record your gallons from the pump. (If you get a receipt, the gallons will most likely be on there. Good place to record the miles.)

4) When you get a chance, divide the miles that you recorded by the gallons that you recorded. Record that number (MPG) somewhere so you can keep a permanent record of MPG for every time you do this.

Special note: If you don't fill the tank, don't reset your trip odometer to zero, but record the gallons. When you finally fill the tank, add those gallons to the gallons of the partial fill. Record & zero the miles & divide those miles & the sum of the gallons for an accurate MPG.

See? Simple.

I believe each RENESIS is hand assembled so this is most likely why most RX8's have different "personality"??

maybe have your dealer do a compression test- my mileage never got above 15, then starting going south, then it wouldnt start, now they are replacing the engine at 3600 miles

Sorry, got ahead of mysef there. if yer from da bayooo just count on yer fingers how many gallons u use and if your rund outa fingers take ur shooz off and counts on yer toes. works goood esp if u got no shooz.

mngpao

but how do they use their fingers and toes if they use 12.5 gallons?

I think this is too complicated for some people. Imagine - a 4-step process (fill, drive, fill, compute) that has to be performed in the right order. You may be asking way too much. And then they're told not to count on the gas guage! Car ownership never used to be this difficult.

8_wannabe

yeah, but you left out the one part about writing something down. that totally confounds some yayhoos.

Hey, we're not picking on anyone in particular here so don't take offense. but for all of you in lalaland concerned about gas mileage just please make sure you're computing it accurately and correctly before posting your mileage figgers on the forum.

Apology accepted. I know the board can be rough sometimes, but remember the purpose here is to get facts from multiple owners, resolve issues, help one another, and enjoy each other's posts.

IOW we're TRYING to help each other, so when some seem to ignore the help, well, you can undertsand the irritation.

And yes ROUGHLY that is ABOUT what miles I have at the 3/4 mark... so back of the envelope calculation 4 x 60 miles = 240 miles. In fact, 7 of my 8 fills have been at 234, 253, 251, 245, 243, 235. But the ONLY THING that tells me is my GAS LOW LIGHT comes on somewhere about 235-250 miles, it tells me nothing of my MPG!

If anyone isnt satisfied with there RX8 I will straight up trade you for my C5 corvette. Long as it has leather and Navigation.

I sympathize with many who are experiencing poor gas mileage. My experience is good gas mileage. Last two 3/4 tanks equated to 11.8 Gallons and 245 miles of mixed driving. This isn't premier mileage but I thing it's exceptable and within the claims made by Mazda.

I don't know what percentage of owners are experiencing the poor mileage but if it is say 25% or lower they probably have something wrong with their car and should be complaining loudly to their dealer.

Again I'm sorry some are having this problem.

mine started at 13mpg then when I hit 2k it jumped to 17 , 18 area

ok my test failed.. i was using 87 but on my way home today i heard knocking at about 6K so i will purch out the tank and fill it up with 93 (again) or 91. i will do the miles count in 2 tanks from now to ensure that all 87 left over is burned out
