Summer i get around 600 to 620km, winters im getting around 500 to 520km - 2013 GX Sport Hatchback Skyactive

I pushed it this time and got like 410 when I had zero bars left. Thank god it was only $40 to fill 49 litres.
I'm going to try and be good for a while and drive like an old lady. See if that helps at all. I feel the same. 400 is way to low for a car this size. But then again its $15 less to fill than my old suv that got 400 a tank.

yesterday on my drive back from toronto to michigan i had to go to 4wd (i almost always keep it rwd) and i dropped to 13.2L.
the last few times i came i've started to fill up a couple 20L jerry cans at the border before coming into canada. Gas is currently 1.51/gal (40cents/L). This way i make sure i can definitely get back to the US before needing to pay over double for gas





edit
what teh shit, was supposed to edit, not double post


you should be fine. My parents always bring their jerry cans when they visit us. I'm surprised they haven't bought even more cans. They only bring 2 or 3 large ones at a time.
if you're already in the US it can save you a good chunk, especially if you've got large vehicles



Say you had a vehicle with a 120L tank, and you filled 6 - 20L Jerry cans, you'd save maybe 50 bucks
Lot of effort for a short term gain. You're also now driving around with 120L of fuel inside the vehicle with you
But this is just my opinion.
I know you go back and forth often and IMO that is worth cutting down any costs associated with your regular commute, so for your case it does make a lot of sense



Imagine the Hollywood style explosion that would happen if you crash!

Down to about 680-700 in the winter.
Summertime gives me 780-830 km per tank. Always fill the tank to the brim.
Car is 2010 GX Hatch 2.0 5-sp.
The mileage surprised me. I swapped this car with my wife. She now drives the 2012 Golf TDI 6-sp. I've had 1200km in the summer, but around 980 in the winter. My fuelly shows 156,000 km with 159 fill ups. That's basically 1000km average for the Golf.

99% highway driving 115 the entire way I average 7.6 over 400 000kms between two first gen Mazda gt's with the 2.3L 5speed. A yearly average between winter with winter tires, hot days cranking the AC, and everything in between. Not amazing but pretty good IMO.

So I drive mainly all paved country roads, 80km zones. I have a 2012 mz3 sport GS Sky 2.0. I only use the 91+ octane. I notice a huge difference when I don't use it. With the 91 gas I can hit 680kms on a tank, but when I use the 87 I get about 550kms. According to my gas cubby app I average 6.9 litres/100kms.



That's not how gas works. Sadly, it's all in your head.
The octane rating is actually an "anti-knock index" number. It has to do with how well a gas resists knocking, which is basically premature ignition due to high compression. That's why sports cars with turbo chargers, or some larger engines, need higher octane fuel. The pressure inside the combustion chamber is much higher, and 87 would ignite prematurely rather than with the spark plug.
You don't get more "octane" in 91 vs 87. The amount of energy produced per litre of fuel is actually the same.
The only possible explanation is if you're buying ethanol-free 91, and your 87 has ethanol, then you might see more mileage. Save some money and just use 87.






ok so I am awful at using the search tool, so I will pose a question in this thread rather than open a new one.
Back in the beginning of June I bought a 2013 Skyactiv Mazda3 GS. I am using it primarily to drive for uber while I am in school. What sorts of things other than more efficient driving (something I am working on after having a heavy foot in my 2008 GT) can I do to improve my mileage?
My mechanic brother in law mentioned he got better gas mileage in his Ford F150 buy installing a cold air intake, and diamond tip sparkplugs.
Would either of these options be worth my time or money? And is there any other mods or things I can do to squeeze out the most KM to a tank?



first ive ever heard an intake will get better fuel economy. 99% of the time is less. you already have ngk iridium plugs so you cant really put in better. i would make sure your intake air filter is clean. and keep your cars service up to date my 2010 averages around 8.0L/100KM and from fuelly 2012 -2015 are getting 7.2 - 7.7L/100KM so if thats what your around then your in the ball park. but check out that site if you dont track your fuel economy.

2014 Mazda3 GS manual with 2.0L SkyActiv
Recently drove to/from FLorida. Average highway fuel economy hovered around 6 L / 100 km but that's with varying speeds (no cruise control) about 110-130 km/h.
Drove back where I was lighter on the gas pedal and got 5.2 L / 100 km - got 770 kms on one tank of fuel, filled up nearly 40 L.



There's not much you can do, I'd suggest pumping an extra couple pounds of air in the tires. Keep a clean air filter. Make sure your not carrying any extra unnecessary weight in the car and finally don't fill the tank right up. Every gallon of gas weights around 8 pounds.
