Fuel Economy

It's great for the 2.5 L engine. Till about 3 squares left.

Excellent, That's skyactiv territory. Just goes to show careful driving can pay off.

Well done

120km/hr is not careful driving lol.

[asyed]

I usually average around 500-530 km before I fill the tank. Depends on my driving though, I usually drive in a somewhat fuel saving manner but not a tree hugging type

lol, what i meant was he stuck to 120km/h and wasnt constantly increasing/decreasing speed resulting in poor mileage. 100-120 is my cruising speed as well

Gotta love cruise control

Mazdas are the Zoom Zoom cars and they get that by being rev happy and more fuel thisrty than others. So don't expect great fuel mileage. To get better mileage drive conservatively below 100 kph but boring. I dsicovered on Mazda 3's 2010+ they have two scoops hidden just under the lip behind on either side of the Mazda insgnia to pull air to the intake duct. I cut out two air dams from plastic windshield washer jugs to force air up the ducts...so the faster you go more air is forced to air box for better mileage...getting 700-800km per tank in winter..GX 2L, 5sp manual. In winter cold air I partly opened air duct at joint above rad to let in about 1/4 warm air from engine to warm air mix with cold into air box. seems to work good for me so far.

Cruise control is not that fun. Didn't use it. I did drive safely along with the traffic, but mostly on the lefthand lane. But I guess cruise control could have a positive effect on fuel economy (see on topic lol).

It's dependent but for the most part I find cruise ruins fuel Eco. Get better mileage without it.

Went to Montreal last sunday to visit in-laws over x-mas, filled up a pickering and cruise control for the most part @122km. Stopped at the last exit before entering quebec to fill up and I was at @425km with just under 1/2 a tank (5 hash) so I figure at this pace I would've gotten another 200km. So getting over 600km on a full tank for a speed3 is dam good.
On the way home (yesterday) drove it the way I like to and got home in 4hrs (cruising there on sunday took 5 1/2hrs), had to fill up @ trenton so @400km for tank. So Peter I think cruise control was definitely a fuel eco in my case ;-)

Way to represent! Nice to see the speed hitting some big km/l numbers.

[peterm15]

. So Peter I think cruise control was definitely a fuel eco in my case ;-)

for sure. Lol.

For my daily commute up the 400. If I use cruise I burn more. I'm assuming it's because of the 400 not being to flat. The trip to Montreal is quite flat so that would make a difference I assume.

Plus. It sounds like without cruise you drive like an a-hole. Lol j/k.

I got gs-sky sport3 2012 now 6600km (first oil change at 5200km), and have a big consumption problem. My car used 8.2l highway (120km/h cruise flat ride 700km), and 10.8l city. I returned back to my dealership. They made a 4 days test drive just in a city (Calgary). After 88km the gas usage 11.5!!! Mazda Canada gave another test description which sad highway one shot 90km/h no bunny run, no cruise... it has 5.7l test result. Same person, same pump, same drive style... How come? We made our own test, same 36km brand new, at the same time my has 3200km, the other was sedan, but drive in a city shouldn't make 1.5l difference during same style driving. The service checked every little details, found nothing. After that I have to pay because warranty not covers to run test like that. If you have a fuel economy problem, you can get rid of it, and buy something else (Lancer...)

..not sure about the lancer comment... but anyway yes driving in the city will increase economy. that is an obvious due to the stop and go speeds so on so forth. im sure in calgary its pretty cold (-17 says the weather network) so warm up time will be much longer as well. but economy will increase as the vehicle ages which if you do take the time to read the 54 pages on this thread you will get that idea that it does happen. i didnt notice mine get better until around 24,000 km. but at speeds over 100km/h economy will increase. usualy its 1% for ever 1km/h over 100 you go. so the car will use approx 20% more fuel then at 120km/h from 100 km/h which im sure the vehicle is tested at. my car on the last tank used about 9.7L/100km and on its coldest day was -22. now at +6 to +14 the last few days it has been decent but with the coming cold temp drop to -6 im sure it will go down again.

so wait until summer or when its warmer and positive temps as thats what kills fuel economy, then add in heat up time. winter tires. short trips and the economy will go up up up.

1) Winter gas (with additives to keep it liquid in cold temps) sucks for mileage, doesn't burn as clean, etc.

2) Cold temperatures means that your car takes much longer to get completely warmed up.

3) Cold air is denser, more drag on your car.

4) Driving through and over snow creates more drag than if the roads were clear

5) Driving through and over snow means that you're mostly in gears 1 - 3

6) Your car is new, it's still breaking in

+1 good way to put it

Well, I'm new here so I'm not sure if this has been brought up, but I bought an '09 GT 2 weeks ago and discovered something about this car - maybe just this one but maybe all.

If the air diverter control for the heater is in the position between the floor-panel mix and the floor - all the air comes out the floor (nothing felt on panel or defrost). If I set it to the floor position, I can feel some air coming out the defrost vent and my AC will cycle on and off. I tried to dig into the dash to get to the panel control but gave up. My thinking is that there is a switch on the defrost diverter that once it starts to open it brings on the AC - normal on most cars today (just not sure where the switch is - could be on control or on heater "module"). Anyway, for my car at least, if you set the air flow to the floor you get the AC cycling and the corresponding loss in mileage.

For those of you interested in fuel economy, the following is an interesting article. No specific mention of Mazda, but it would be safe to add 20% to Mazdas estimate. For my 2012 Mazda 3 GS-Sky auto that means a reasonable target of 8.5/6 litres per 100km.

m driving a 2013 Mazda 3 GX w/AC, automatic and 7000kms on her. I'm getting about 500kms out of a tank. I fill her full, and run her down until the last bar. I'm estimating I get 500kms based on 250kms per half tank.

Let me know what you guys are getting and what you think about my consumption!

[Booter22]

my 2010 3 2.0L 5Spd with 94 000 km and with a cold air intake gets about 550-620km per tank still. but i do about 75% highway

[Hotsky]

When I let my wife drive my car for a month this past June she was getting ~600km per 45 L, best mileage was 7.1L/100km with my '05 2L Mazda 3. Mostly highway driving tho. I never get those numbers

I'm doing 75% highway too, Ryerson U and west Mississauga. I'm not heavy on the gas either so it's really bugging me!

[chao_zu55]

I'm in the same boat here
I do about 80% hwy
I commute to work on 400 everyday, about 40 each way...
I'm at 29000 km with my car with reg maintenance through the dealer.
I'm averaging 600-650 a tank an I never go over 110, I jump on the hwy and cruise.
During the last year or so the best I've done was just over 700. And it just seems the 7 disappeared. Im not sure what else I can do to I
Prove the economy but this car has been disappointed in the fuel economy department...

Impressive mileage, but unfortunately the maintenance costs (timing belt change on these must be meticulously followed and is expensive) of the TDI are high, and especially repairs.

Don't waste your time get a diesel. This is why I traded my mazda....



This was my tank a couple weeks back strictly highway and still had at least 200kms till it was out. Food for thought!

[iiliu]

I have a 2.5L 2013 hatch. Averaging around 10.5L right now, half city driving (north york area) and half highway (north york -> mississauga on 401). What do you think? I think I may have heavy foot
