Your still in the break-in stage, so almost certainly you'll see an improvement as time goes by!! At Break-in I was avg 9-10l/100km after and presently I'm at 8-8.5/100km on average.I consistantly get about 550km per tank city.Quote:

Well the results from my second fill up are in for my 2.0 ATX:
29.76 litres pumped after 425 km driven for a fuel economy of 7 L/100 KM on the nose. Not bad, not bad at all. This is 100% highway driving though.
when you post your numbers please include your engine size and tranny auto or manual...just a suggestion
Thanks
when you post your numbers please include your engine size and tranny auto plus speed 4 or 5 or manual...just a suggestion
Thanks
this was my situation as wellQuote:

I have a standard GT so I'm hoping to get in the 8-9L/100km range once I get through the break in period.
I thought standard was just another term for manual. Since most cars come standard as manual unless you specify automatic in which case they charge extra.Quote:

My best so far I think was a 7.3L/100km...but that was about 95% highway.
D'OH!!! You're absolutely right, I just didn't read your original post where you mentioned you had a manual (or standard, same thing :))Quote:

It should. Then again, it depends what kind of mix of city/hwy you do. To get to my job, I do about 95km/day in terms of driving. about 70% of that is on the hwy. So for me, it's pretty easy to average somewhere in the 8's in terms of L/100km. Then again, I don't use AC and I try not to gun it off a red light (most times XD).Quote:

ya my milage is all over, it seems like the past week i havent used the AC at all since the weather was frigid and it was the first time i got mileage over 600km to a tank. usually i only get around 500-550. so it seems like the AC makes a bit of a difference, i still avg 9.1L/100km which is not very good for a 5spd
before i installed my intake i was avg'ing 8.6L/100km
i'll have to see what i am now since hitting higher RPMs is much easier
I was avg'ing roughly the same. First fillup after the intake, I was at 8.1L/100km. While not a HUGE difference, every little bit helps to me XDQuote:

I'm confused...your gas mileage improved after installing a CAI??Quote:

From everything I read, if your driving habits remain the same, people were saying that the mileage would be better as with more air coming in, the engine has less work to do..which is true since I notcied the RPM lower with the CAI. Not a HUGE difference...about 500 revs? So either I drove "better" than I did before which isn't really true since I drove about the same as before...or the CAI helped that little bit. Only way to find out that this wasn't a fluke is to figure it out over many fillups. But normal to and from work only, before I would normally avg. 8.6L/100km. This time, it was 8.1 and the KM remaining always added up to be better mileage than it was getting before.Quote:

The first fillup after I installed the CAI (drove 1/2 tank without it and then 1/4 tank with it), it said 640km remaining and when I filled up, I had drove about 532km with the remaining km at 40. So difference is about right...and if the trend continues, that's about 40km more per tank.
Interesting! I just naively assumed that installing a CAI would somehow make your engine consume more gas. I never really thought it through.Quote:

Oh, don't get me wrong. That's what most people said. And I noticed that too. When I REALLY step on the gas, I noticed when watching the KM remaining and consumption, it goes down FAST...but if you are conservitive and don't do it often, it seems to help a bit.Quote:

That's an excellent mileage especially for a brand new engine!Quote:

800km? with a GT? is it Manual?Quote:

Wish my fuel economy would see past 400 a tank.

I gotta tell you I question you getting 800km easily on a tank unless of course its 100% hwy doing 80 km/hr with the wind at your back and coasting down hills, otherwise you are the holder of the most fuel efficient Mazda3 in Ontario.

i love my music loud, does anyone know if like A/C, a loud stereo have any difference on fuel economy?
A/C does for sure....i don't think listening to music loud does anything other than put wear/tear on your ear drums lol
Maybe by listening to loud music, you want to drive faster to a good song and thus use ore gas?Quote:

so how does a/c put so much strain on the engine that would produce a noticeable difference in performance?
you've got me there.....Quote:

Any time you are running a lot of your vehicle's electrical devices it puts extra strain on your engine (i.e. A/C in the summer or the rear defroster, heater, seat warmers and wipers all at the same time in the winter - that can put a strain on the engine too!!)
Always limit the electrical stuff you got running on your car to only what is necessary and you'll have a happy engine. :)
I get an average of 7.9L/100km and I drive a 07 mazda 3 2.0L Manual :)
Hit it right on the head! When the compressor is activated it probably robs the engine of about 10-15hp if not more! It also robs a slight amount of HP even if its not on, just turning the extra pully, even though the pulley is free turning as the compressor uses a clutch mechanism.Quote:

I have an 08.5 Manual GS, and I've been getting approximately 6.4 l/100km (about 90% highway).
Needless to say, I've been pretty happy with the mileage out of my car.
90% highway...I think that's the key :)Quote:

Same with the major electricals, like rear defroster, makes the alternator work harder, causing more drag.
I'm not sure if they are available (haven't looked into it, not top of my list), but an "underdrive pulley" can alleviate the drag, increase fuel economy and hp. I put one on my 86 5.0 Stang, and man did I feel it! Quick throttle response, more intense acceleration. Didn't pay attention to fuel economy though, that mustang didn't have any! :chuckle
I thought I was the only one getting bad mileage but theres a few people here getting the same as me. Ive got an 08.5 GS manual with about 1500km on it and im getting about 405-415km on a tank which isnt very good. Im also new to driving manual though so maybe thats got something to do with it. Im trying to change the way I drive to see if it has any impact but does anyone have any pointers, just common mistakes that new drivers make which might improve mileage?
I drive a 04 GS. When my car was stock I was getting numbers like Trinidad(700+ pure highway). Now I get about 550, If I'm heavy footed 400-410.
Here are some tips:Quote:

Then there are the "HYPER MILERS." These are people dedicated to extracting the most mileage out of any vehicle. They do some by driving in the most conservative manner possible. This is a religion to some people and they compete to see how well they can do. Warning however, this type of driving is boring!
