Manual is always best. A computer can only do so much.

Hello,
Its been a year since i been driving my 2010 Mazda3 GS (automatic). I live in canada and here it snows a lot. So considering that on an average i am getting 25.1 mpg from sep 2010 to aug 2011- In between i have missed about 8 fuels up (4000 kms). Right now i have 17000 kms n the car. Is this a reasonable mileage am getting? I mostly drive 65% city. As not many highways here. What is the actual mileage that other people here r getting?
Thanks

I get about 18L/100km, in my SUV so enjoy the great fuel economy everyone lol

Teehee... 5.2-5.3L/100km mixed city/highway.. more rush hour in the city since I live right in downtown.

Wow that's amazing! Only downside is that it uses premium huh? Does it still work out to be cheaper?

Also, if you guys wanna track your gas usage, you guys can use www.fuelly.com

You jelly?

LOL!

You jelly?

lol thats because you are filling it out wrong. some how you have 3 fill ups and have tracked 49 KM, this its time to check your entrys


heres mine

[Awjvail]

Lol, okay I figured out where I went wrong. The mileage on my 2nd fuel up was off by a lot. Guestimated the mileage but now it is too high... I can say for certain that my 3 isn't getting 30mpg.

[Awjvail]

y'know what.. I'm just gonna delete that fuel up lol.

[JP3]

Just did 8.5L/100KM on my latest fill-up for my 2nd gen 2.5.

[old-guy]

Trying to be fuel efficient. Shift rpm <3000.

4 fill ups 9.6/100km hope it gets better after my first oil change

[A6X6L6]

Everytime I fill up from practically empty.. like at less than a bar left... It kills out at 48L... do I really have a 12L reserve tank??

Also, I sometimes put in 91 just for the air miles @ Shell, I feel I get a bit of extra milage out of it and my car seems a bit more peppy (2.5L) or is that just psychosomatic??

[A6X6L6]

less than one bar left*. Ps- Can I edit my posts once posted?? lol

[Fuyuzora]

Can edit once you hit 100 posts. Even then, you can only edit for 12 hours after posting, though.

Using 91 is a waste of money and any perceived performance gains are purely placebo effect - octane is added to prevent detonation in high-compression engines. In a normally-aspirated Mazda3, additional octane is of no use. You can theoretically travel a bit farther on some brands' higher grades though, because they will have less ethanol content. For Shell, 87 is up to 10% ethanol; 89 up to 5%, and 91 is ethanol-free.

In most cases you should probably just stick to "regular", 87 octane fuel though.

As for the fuel capacity on the 2.5L 2010s:

From what I've seen in my MZ3, the light comes on with 15L remaining, and the final fuel bar disappears with 10L remaining in the tank.

Well this is my MPG after 4 fillups.

Slight improvement this week... 2000 kms on the odo.

I did the second fill-up today on my brand new '11 Sport GS with the 2.5 litre engine. So far I am averaging 8.2 l/100 km. That's with50/50 highway vs. city driving. This is much better than I had been expecting.

I get 500-550kms to a tank with my boosted 2.3l on 91oct.

[Sonic31]

My handy dandy Gas Cubby app is telling me I was getting 9.1L/100km before I cleaned my throttle body.

6 tanks after cleaning and I am now getting 7.9L/100Km.

Only other engine mods I have done are K&N Panel filter and the Throttle Body ground.

Usually get about 550-615km/tank.

Not bad for an 06 with 200,000Km

[RTEnthusiast]

4.1L/100km on the last tank. Mostly highway, a little bit of city. Weeeehooo.
