I have a 14 Mazda 3GS 2.0 auto and ive had an overall avg. of 7.8L/100km and its since dropped to 7.5 from the warmer weather and less idling time and I'm at 16000km so come even warmer weather i should do well at the pumps.
70/30 hwy/city. "ish" depends

Guys I assume I'm doing something right cause I generally get about 600km/tank and I gun it every time I get on the highway. Foot down with red line shifts. I dunno, plus I drive like a ricer when I'm in peterborough. I dunno... 2009 3i Sedan




how do you drive like a "ricer" turn the neon lights on and pull out the fart can exhaust? or do you mean like an idiot cutting in and out of lanes and cutting people off.. yea no one needs people that drive like that so hope its not you. but if so glad your ricer driving is in peterborough
For the winter time I had 17" OEM alloy rims with Michelin X-Ice 2s, and now I have switched to 18" OEM MazdaSpeed3 alloys, and planning to burn out the stock Dunlop Sport 2050s before I get new tires. I've noticed the my fuel economy has gone from usually around 10L/100km during the winter time 40% highway 60% city (i have a 2013 2.5 GT hatch) to about 11.5L/100km (this is all city driving so far because I've only tested for one day so far). The gas mileage is unusually high - given that it no longer has winter tires on I was thinking gas mileage might go down... I get that my rims are now bigger and a bit heavier, but is it normal to make that much of a difference?



This winter has been around 15-16L/100kms for my speed3



But there might (hopefully) be a few minor leaks which is making the car work harder to maintain my driving style
I guess I just assumed it would be better because winter tires have come off and they're usually worse on mileage. I guess these tires are a bit stickier and rims bigger and heavier. It's actually gone down to 10.5 now after a bit of highway driving. Haha I guess I just hoped it would go down. Oh well! Thanks guys


I'm also getting my numbers back up. Just did a full highway drive and got 350 at the half and 605 before the light came on. also doing about 125 the whole time since Ohio and parts of Michigan posts 70mph as their speed limit



sadly mine isnt really going up. mind you still have the winters on. i think my last tank i got about 350km from it.. but it did last me over 2 weeks before i filled it up. so that beats the every 4 days from before. will be interesting to see how the short drive to work gets to the car. if at all



Mine is going to be down, cause rims lol. I can tell they are heavier. Must look into weight reduction LOL



mines pretty fuel Effiicient. Check out my fuelly

Ill report back at the end of this take of gas on how much worse it is


My 2012 MS3 L/100km's keeps going downI was at 11.8 this winter and now I'm at 9.8 with my summer set-up just going on yesterday. That is about 50/50 City/Highway.
Edit: Forgot to mention that it is with "some" aggressive driving and I cruise around 120 on the highway when traffic permits.
