I think it's the cold climate that is givin' me these bad MPG....or maybe the car is still new, i'm only @ 2000ish km...
i voted for 19-21MPG @ 55-65MPH....
are there any significant MPG drop if you drive over 65 MPH?
thank for the info, i think i will get that scangauge so i can do math like u :yesnod:I've gotten 28+ on a full tank doing 90% highway driving, when I was bone stock, green engine with about 500 miles on it. Weird mix of highway though, included mountains, so charging uphill at 90, then coasting or engine braking down.
In the more usual city mix of driving, I'm sitting at low 20's. Still not bad...if you just don't beat on it you stay out of the super-rich part of the powerband that dumps gas.
Winter driving definately makes a huge impact, I don't let the car sit and warm up, but the ScanGauge tells me I'm dumping about 1 Gallon / hour at idle when the car is cold. When it is hot, this runs about .2 - .3 GPH. Most of this is for emissions to light off the cats faster, that's one other reason our intakes have the variable tumble valve in there. This isn't terrible though, I was looking at GTOs before I bought this....and their idle averages 3.0 GPH when cold and barely under 1 GPH when warm. Add to this the fact that Mazda takes my entire 10-15 minute drive to warm up....and I like to drive my beater to work on cold mornings.
Sure, it leaks a little fuel when it's cold ... but it sure is warmer inside!
Well form the poll the Dealer is lying, u got to have it check by another speed 6 dealer cause 11mpg :shocked: :shocked: to the square.....i have gotten 11 mpg since i bought the car, i fill it with 92 (best i can get) and i dont race or run the car hard the dealer has been unable to fix the car in 2 trys now :swearin: first they blamed it on a bad bov now they are trying to tell me all speed6 get poor fuel mileage. most of my driveing is stop and go at low speeds and its cold here in Mn.
the car is stock
there is only one other dealer near me and they have the same mazda rep so they will not fix it, they are saying "mazda warrenty does not cover bad mpg and that there is nothing phisicaly wrong with the car "Well form the poll the Dealer is lying, u got to have it check by another speed 6 dealer cause 11mpg :shocked: :shocked: to the square.....
Maybe slightly off topic, but how goddam hard would it be to include an effing MPG and trip computer in the design of this car! My ten year old VW has one for God's sake... The car doesn't even have to use a physical key! It just knows I'm there and welcomes me in. It uses mother lovin satelites in space to tell me the quickest way to get the closest IHOP, and has one of the more advanced engines known to consumer autos, but it can't tell me the basic math of how many miles I am getting from each gallon of gas it uses....
Anyhoo, I voted for under 18mpg w/ mostly highway driving. Frustrating, yes... but that boost (and whooooosh/pssst) does things to yer mind.......
