Actually -- if you check out this web page: http://www.miata.net/garage/tirecalc.html and submit the tires for comparison, you'll find that because of the low profile on the 17's it appears that (contrary to my own tests) the 17s are 1.2% SMALLER than the stock 15s. (i entered 185/60R15 compared to 205/40R17)

.... so if anything, tire size should be marking us with 1.2% better milage than we are actually getting... according to that web site.

The worst i have gotten was 26.

 

if you drive around from full to empty on 1st gear the whole time... just maybe... and maybe.... you'll get about 21mpg...

 

Wow!

Very very intersting!

Thanks for sharing that!

 

I got a solid 36mpg after an all day driving like a madman excursion. City driving mixed with 85mph and 36mpg.

Does anyone else have difficulty filling up their tanks without the hose shutting off?

 

I was about to throw that question out today actually. I have a new RS1 and I have filled it up 3 times. The first time not a bit deal, i thought it was just the pump. But just filling up today I had to actually stand there and hold it, only squeezing the pump half way so It would fill.

 

This really ____ed me off about my mileage.

My first tank I got bout 320 miles on a tank.
This last one I only got 290.

I seriously have no idea what in the hell happened.

So today when i filled up I also pumped uo my RS tires to 50psi.

i hope that it helps.

i know that the engine still needs to be broken in, i am only on 940 miles, but still 290 on a full tank, mostly highway driving, that really ____ed me off.

I still love the car.

 

It seems to be only some gas stations, some of the times, but it is definitely an issue. I wish I knew the answer to the question

 

My Fiance's xA started out only getting 25 mpg AVERAGE. It has since improved to a whopping 29 PMG. Yes, he drives like a lunatic sometimes, but we are both disappointed with the gas milage on our scions (mine is an xB and it gets 29 mpg average.)

 

I'm having the same problem trying to fill my tank. I have to stand outside the car, hoping that I don't accidently overfill the tank. I also want to make sure that I'm getting a full tank, because I travel frequently, and don't want to have to make a lot of stops. Does anybody know why certain gas stations do this and not others? Is it the station or the car? This would be really nice to figure out...if anyone has an idea. I need to know if this is a problem I can fix, or if I have to take it in to fix it, or if it's even fixable. Thanks.

 

best I've gotten is 38mpg or so, average 34mpg (mixed highway and city driving) and the worst is driving 90+ and got 27mpg

I have never seen 40+, how anyone can drive and get that I'd love to know

 

When I first got my xA I was getting 36 MPG. That lasted for about 6 tank fulls. I am now down somewhere between 33 and 35. I don't think the drop off is due to changes in the car, I really think I started driving the car harder. My best was just a bit less then 37 MPG on the second tank full.

I have also run into problems trying to fill up my RS. The pump was fueling normally until it hit about 3/4 of a tank, from there on I had to hold the pump and squeeze it in manually. I was also nervous about overfilling.

 

I think I may have won, the worst...

12.67mpg
honest to god truth.

how? follow this link,

I cant seem to get the pump to stick either? anybody knows what's the reason?

 

That's something I was wondering about. How are xBs with milage? I can see how they would do ok around town, but I wouldn't think they would do well at all on the highway. After all, they're about as aerodynamic as a brick wall.

 

For me, it seems to depend on the pump. Happens only rarely for me, but I've never had the instint listed above regarding 3/4 tank. If the pump doesn't lock on, it happens almost immediately.

Fortunately, it's only about 9-10 gal. to fill, and that goes by fast.

 

All this MPG i get about 280 miles per fill up at about 70mph
but I have to ask.....

Whats up with the high RPMs.... Its weird to see it over 3000RPM like it needs another gear :?

Or am I the only one with those RPMS at 75mph???

 

There is a TSB out for this now. It replaces the tank and filler neck with a new design.

 

I think we are all experiencing this -- manual transmission is higher than auto in the higer speeds... but it is all about the gear ratio. A 6th gear on this thing would do WONDERS imho... i'm hitting 4000 rpms @ 80 mph -- no wonder i get 28 mpg at those speeds!!
