I drive the 2.0 liter 150 hp 2016 Mazda 3, and I do baby it most of the time. If there's even the slightest downward slope, I drop it into neutral and coast. I seldom drive the speed limit (usually a few mph below), so I'm definitely not your average driver. I will add, if I'm in a...

I have a 2010 Mazda 3s 2.5 and I get 26.3 average. Just curious what mpg you guys get with any model or year Mazda 3 modded or not.

I cross shopped the Subaru impreza and cx3, on paper my awd 3 crushed them and buying this turd was a no brainer. Things I've noticed since then. Every corner of the car clunks when I take off. Android auto goes full tilt and shuts down 3/4 of the way to every destination. I have to keep the...

So, I have a new 4 door AWD premium. For the first 1500 miles, I was averaging about 27 MPG. All of a sudden, the MPG started dropping precipitously throughout all kinds of driving (city, highway, etc.), until finally settling around 19. After doing this for 2 weeks, it started picking up again...

Good morning, Just got a 2L Mazda 3 Automatic. From all the blerb on Mazda site it says on avg 45% mpg!! I am currently getting 31.6 mpg. Costing me an absolute fortune in petrol. Does anybody else have an auto to compare with?? Thanks Andy

Greetings Fellow mazda misfits , can any one help / or guide in the right direction for the following , Losing my peace of mind in searching this ( manual book informs only type A and Type B cluster information ( Bone stock is type C doesn't say anything about this) We picked up new to us...

In my quest for increased fuel economy, I've come up with an idea that I wanted to run by you guys... "Economy" and "Economy+" settings for your air conditioner: - Economy mode would only operate the compressor when the throttle input is at 0% for 5 seconds, regardless of whether or not you...

So it's been a while but now I have a new concern:|: As I mentioned in a post somewhere else, I just took my 2014 3 sGT to my dealership for a 35k service and brake replacement. Upon its return everything seems alright however one thing is different. I usually keep my "info" pane on the...

Any issues with Mobil 1? I've used it in everything else (save for a few w126 oil-burners) and haven't seen any issues.

Howdy all, Before I go and jack it up and start spinning the wheels around to be 100% sure, here's what's going on: I have a noise coming from the front that almost sounds like a UFO, it is NOT a grinding noise. It's more of a whoowhoowhoo or brushing noise that increases in speed with my...

Hello all and that you for any help, My mpg has deteriorated to a point it shows 4 mpg at very low and city speeds feathering the throttle. at highway it is at 33. when I got the car it was nothing like this.. was getting constant 23 at city at 35 at highway. my car in a 2.0 165bhp. Any info on...

Hey all.. brain dead right now. Just trying to figure out cost of MPG increase. Not sure about everyone but where I live, the grades of gas are usually $0.10 difference. So for example right now... 87 = $2.79 ... 89 = $2.89 ... 91 = $2.99 So say I do a mod or change Octane that increases my...

Hello everyone. A few weeks ago I was halfway done with a 2000 mile road trip, when I got my oil changed and tires rotated at a dealer in St. Louis, MO (it was a dealer I purchased the car at). After, I noticed an immediate average drop of 10mpg, which is just sickening. By the time I...

Hi I'm considering getting a Mazda 3 2.2D sport NAV.. My only concern is the engine size when most of my mileage is on local roads... Can anyone advise what they get in the model on normal local roads? Thanks

Car computer MPG waaaaay off? my tripometer said 240 miles. mpg screen on infotainment system said 37mpg avg. (I reset it every time I fill up.) I filled up 8 gallons. 240/8 = 30mpg! huh?

2015 3i Sport, 3k miles the electronic fuel gauge is garbage! when it's on E, I have between 2 and 4 gallons left. :surprise: so I got to thinking about estimating the # of miles left by multiplying the avg mpg for the current fill up x fuel tank capacity (13.5 gallons.) minus # of miles...

I just filled up. I reset the dashboard mpg and started the car. I drove about 20miles. dashboard says avg= 33.5mpg but the console says avg= 31.3mpg for this current trip?! huh?

in the Highway MPG thread, someone mentioned that he got on his 2.0: With cruise set at 65 mph, average mpg is 32.0 mpg. With cruise set at 63 mph, average mpg is 38.1 mpg. is 63mph the magical Holy Grail optimum point? and why does going 2mph more kill the mpg soooooooooo much?

This issue had been bothering me for a long time and I would LOVE to get some input from you guys. I have a 2010 Mazda 3 iTouring with the 2 liter engine and auto transmission. A while ago I suddenly noticed that the car was driving draggy-- both when accelerating and when coasting. It almost...

I have a 2015 M3T manual, and I am getting anywhere from 21mpg with not trying to baby it, to 22-24 mpg with trying to carefully watching the current MPG and making sure I am keeping it above 30+. It's rather annoying that I am fighting so much to try and get better gas mileage. My GF and I...
