Just finished my very first tank this morning. 253 miles/13.492 gal = 18.75mpg (light came on at about 245). A little lower than I hoped for, but I'm ok with that. What really hurt though was freaking $2.50/gal for a fill up with 89. Ouch!

Twin 8s!

By the By....

My mileage got better as soon as I started using 91 octane. Owners manual states that 91 is the "Premium" grade the car was designed for.

I have noted others using less than 91 and also getting good mileage. I keep mine at 90-91 by mixing 87-89 and 93 octanes. Hard to find 91 here.

As I have stated in the past, I think some of the mileage problems are related to the local gas types and quality.

As for me, if I am averaging 21+, I am getting what Mazda advertised as the MPG for the vehicle... and having fun.

I have 2800 miles on mine - I use 87, 89, or 91 octane and have the most recent flash. I tend to get about 18 mpg in mixed 70/30 (city/hwy) driving. The last long trip with all highway miles was before the M flash, so my all highway number should go up. ( I think the tanks at all highway were ~21 mpg). I seem to shift before 7000 rpm (mostly). Shifting to 5th for crusing in town (~40-45 mph) seems to keep the gas consumption down, but what fun is there in that? Life is too short to drive boring cars!...

i dunno about u guys (i'm still in the first 1000km), but i haven't gotten more than 360km out of a tank yet.... and thats going almost to the limit. filled up 57 Litres out of 61 Litres(total) once and only got 355km on the trip metre.

Sounds about right. First couple of tanks went thru lots of stop and go driving was around there. These days getting almost 400 km.

If I drive all city driving I get 13 mpg. With all highway driving I get 24 mpg. My light typically comes on a 240 miles.

Since the M flash, my yellow light comes now on around 290 miles, no matter whether I drive 60 or 80 mph.
I do not "cruise at 6000 rpm" as I suspect some others here are doing it.

Got around 200 per tank on mine no matter what style of driving or grade of gas. Best tank was 240 with 100% highway driving (cruise set at 65).

MPG issue was one of the reasons I no longer have the 8.

Bet that 15.3 gallons caused you a shiny penny. I have to go every half tank to make me feel better about spending the money on gas eventhugh it all comes from the same monthly budget.

I get about 180-190 mi out of a tank. Have not yet gotten the M flash, but don't think it's gonna do much for fuel economy.

260+ out of a tank...21-23 MPG.
