canucks w/ bad gas

[tonyd]

anyone have the same effeciency problems as me...21 l / 100km?

[xenz]

Mine was 18L~19L /100Km with the first 3 fill up, there after I see it going towards 16L/100km, now I'm on the 8th fill up and I'm around 15L/100km.

a) how many km on the odometer ? if less then 2500km expect poor milage. even above 2500 still can't expect much as proper "full" engine break in > 10000km if you follow tradional engine break-in method.

b) using > 91 oct gas ? using gas with methanol doesn't really count.

c) heavy foot ? I try to stay under 2500rpm so the turbo won't kick in. with the PCM firmware upgrade 2 weeks ago, I've enough power below 2500rpm.

just my 2 cent.

[tonyd]

thanks for reply
odo = 18000km
fuel = 91 or better, no corn oil fuel
i drive like a pussy cat just to see if i'm the issue, plus my wife is the primary driver.:rolleyes:

[muskielure1]

Now that I have 6500 km on my car, I have noticed an increase in efficiecy.
With a lot of city driving, I'm 15l/100km.
If I do a lot of highway driving,I can bring that down to about 13.
Has anyone ever done a check on who's gas gets the better milage(Petro Canada, Shell, Sunoco, Esso)?

[zooozooo]

personally i used to use ESSO, but since i brought my new CX-7 i filled with Shell. they have better gas...after i ask my friends, research....:D

[jp45654]

Petro Canada's premium can contain "up to 10% methanol". Shell on the other hand does NOT contain methanol. IMO, better bang for your buck. Not sure about Esso and the rest.

BTW anyone use midgrade without any adverse effects?

I dont dare try lower grade... on my gas lid it says premium gas so i stuck to it.. i get about 420-450 km on a full tank.. car is at 21k kms now...

Just installed a aem intake.. lets see if that helps or hurts the gas mileage..

[gibson00]

Hi all. My 2001 Jeep GCL is needing constant repairs, and I'm starting to browse for a new car.
Is the mileage really as bad as you guys say???
My Jeep is about 15.5 l/100km which I honestly thought was terrible. I spend a fortune on gas.
The mazda website quotes, for FWD:
12.7 city
9 highway

From what you guys are posting, the quoted mileage is off by, what, 20%+??
I love the way the Mazda looks and drives, but not sure about wanting to pay for the same amount of gas as my Jeep.... :(

My results have been almost identical @15l/100km city & 13l/100km highway. If you do the math, this is 18.8 mpg city & 21.7 mpg hwy. This is a far cry from the 22-city & 30-hwy that were advertised when we bought the vehicles. I'm now at 22,000 kms, & it's been the same since 5,000 kms. Before that, it was slightly worse.
I just got back from the dealership, & the service rep (who's been there a long time) told me that I was the first person who had complained about the mileage.

[Claude]

I'm looking to buy a CX-7 but seeing your fuel economy... :mad:

[Raider]

I have a FWD, and we get 22-25 MPG. If looking for fuel economy, Mazdas are not for you, as they are just more fun to drive. Go drive one, you will want it!

Keep in mind too, these are turbocharged 4 cylinders moving a 4000 lb vehicle..

[Claude]

Yeah! had a Protege 5 so I know... I have a Nissan X-Trail that does around 26 US MPG in average! That's the same as my P5! Mazda has definetly a problem with gas!

[MAZOOM]

The X-Trail, is um, yeah.

If you take it easy the MPG should be fine after a few thousand miles, but don't expect good MPG from any SUV weighing in at over 4,000 pounds with the driver.

[Cue]

I use 94 Husky Gas in Calgary...... there grades are 87, 89, 92, 94 (Gold). Every other gas station in Calgary tops at 91. Husky you can at least get 92 for the same price as the 91 of Shell or Petro.....

[Claude]

yeah I know... I'm not comparing my X-Trail with the CX7 but I'm disapointed with the fuel economy. We have an Odyssey that weighs more, has a V6 and is more fuel efficient then the CX7! Does the 08 have better tires or they wear out after a year has I saw somewhere else?

[MAZOOM]

The V6 means nothing when compared to the T-4, they both have high output and that's all that really matters, and the Oddy doesn't come with AWD, it also has low rolling resistance tires.

Most of the people complaining about MPG have AWD, I know because I have AWD and if I drive aggressively, the MPG will be very low, FWD and you're in the 20's.

[Claude]

And the Ridgeline which is also heavier, less aerodynamic,with truck tires has the same consuption as the Mazda! The Santa Fe is equivalent on gas but has 16" tires. The most I compare, the less I'm impressed!

[MAZOOM]

The Tribute, CR-V, Rogue, are all waiting for you. MPG queens.

None of them drive like the CX-7, look, handle, etc. The CX-7 is for someone that wants a little more excitement out of their CUV, not MPG.

[Claude]

If only they would improve that! The RAV4 has an impressive V6 and does much more MPG! But I really don't like the shape of it neither the back door! The CRV has a lawnmower engine so does the Rogue with it's snowmobile tranny! That let's the Santa Fe... engine is a bit better on gas mileage and tires are cheaper but ride is cushy. My choice would be the Pilot or Ridgeline but too expensive for my budget! Looking at a Civic makes me depressed.

[MAZOOM]

Check the real world MPG for all the models you're considering, AWD CX-7= 100% city 15-16 MPG
FWD 18-20 MPG
Highway you're looking at 22MPG for the AWD and 23-24 for the FWD.

If you we're to go and look at the RAV4, Rogue, and CR-V forums you will find that the MPG is less than impressive, and I'll bet you any money that the impressive V6 only gets that MPG when it's being driven like a CR-V=useless V6 for mpg.

The Rogue has been a disappointment, some (like five, ten people) are getting a whopping 30mpg on strictly highway driving, others(15-20 people) 17-24mpg in city/highway.

The RAV4 has some people posting impressive 25 mpg in mixed driving, mostly, others are getting 17-22. As you can see, no the RAV4 is not impressive with the MPG all around.
It has a bland interior, and a tippy feeling, and a jerky 5-spd auto.

[Claude]

As one reviewer said: "It gives as much juice as a V6 but drinks like one too, even a bit more! That's a big negative point when you see gas going up!"

[MAZOOM]

As one reviewer said: "It gives as much juice as a V6 but drinks like one too, even a bit more! That's a big negative point when you see gas going up!"

It's a big negative point to purchase almost any CUV/SUV if you're really concerned with gas prices, then the hybrid SUV's are pretty ok on the gas, with the Escape hybrid being the best sipper.

[Cue]

Wonder how the RDX or Murano does with mileage. Quickly looking at some forums, I see they have about the same rate as the CX-7's. Anyone know this info?

[MAZOOM]

With the RDX, the city mpg is pretty much the same for the majority of AWD CX-7's, and the highway is a little better for most.

Hello

I bought my cx-7 2008 black chery mica 2 mounts ago. I love it!
I have already did 4500km and I think have resonable mileage compared with competition and car size. I do daily around 80km half city half highway. The worst it was 13l/100km (using the turbo a lot), the best 11l/100km (keept the rpm around 2000-2500). Usualy I fill the tank every 525km and always is 60l or 60.5l for refil that is around 11.5l/100km Sure I would like it a litle less gas hungry, as they advertise it but. I would try to put synthetic oil when oil change, to see what is happened.

[Claude]

That's what I think... when you go easy on the pedal, it's not dramatic. Does the suspension smooth a bit after a while cause I had one for a day and after I took my X-Trail back, I found my ride a lot more comfy.

[MAZOOM]

FWD? Glad to hear that you love your CX-7!

[ScottR]

Measured my mileage a few tanks back...was getting 13.1 MPG. Seems a bit better now, but have to figure out mileage at next fill. Think it'll be better, as snow's almost gone, so not as much stop and go traffic.

Scott

[islandcx7]

just a wondering but does winter tires also affect your mileage gas mileage?

[ScottR]

islandcx7...I think it does a little, but it makes me scratch my head...less tires spinning should be a good thing, right? :)

Scott

[Cue]

Hey Doro... I noticed your using km's... what gas company are you using to get 525 per tank?

[doro]

Hy Cue

I have used 91 octanes by Esso and few times Petrocanada 94 octanes. I did 530km/60l with Petrocanada but few dollars more per refill and not much difference in power increase. I still use the original 4 season tires.

[boosz]

Ok... My first ever post on the forums, YES.... I've been thoroughly DISGUSTED with the fuel mileage on our '08 AWD... Averaging 20L per 100km... Let me back up a little and say that I have a 15 year background as an Automotive Tech (driveability specialist), so I played it up a little at the dealership to see what their response to my complaints would be if they had no idea that I in fact know how things work in a car. The dealership could find nothing wrong, ensured that any recent flashes had been done and that it had the most recent one (as of January '08). Their only advise was to drive it until it reached this magical 8000km "breakin" period and it should improve!! LMFAO!! I don't know what manufacturer in this era builds a motor that must undergo a rediculous period of break in such as this, but that was their solution. SLAP to Mazda!! Well.... 9800km's later and NO change in mileage. As I have access to equipment (and know how to use it) that most may not, I thought "what the heck"..... might as well flush the injectors and upper intake assembly and see what happens.... Immediately PRIOR to flushing, I filled the tank to the top... drove from home to the shop, preformed the flush service, changed the oil (Mobil 1 full synthetic) drove to the nearest gas station (next door) filled the tank back to the top travelling a total of 108km's, had used 21L of fuel :eek: . After driving the exact same route to return home at the exact (as safely as possible) speed back home, stopping at the same gas station and filling back up, travelling 104km's Ai had only used 13L of fuel this time!! Hooray!! I will be monitoring the consumption over the next few fill ups, which will HOPEFULLY be alot less frequent than it has been!!

[boosz]

As a little side note.... Performance seems to be quite a bit better. Turbo lag is much less and acceleration is more what I would expect from a turbocharged car!! I absolutely HATED this car since picking it up because of the fuel mileage and not so great performance... I might actually be enjoying it... I must like it a little bit better now.... After searching around here, I'm considering a CPE exhaust...lol... sssshhhh don't tell my wife it's actually HER daily driver!!

[Cue]

It's gonna pretty tough hiding the exhaust from her..... will be noticeably louder. Really, if you want a very nice performance upgrade, get the Forge BPV. Bout $170 and very easy to install. The stock valve leaks boost big time.

[adza22]

yeh it's a it's a guzzler :p

[boosz]

I'm not all that worried...lol... she likes the sound of my bike, so I'm sure she'll like the sound of the exhaust after... I was looking into the BPV as well, but I'm not about to do ANYTHING if the fuel mileage doesn't improve at least to an acceptable level..

[Raider]

Well, not sure if it matters, but we got 23.9 MPG on the last fllup with our FWD CX-7. We have the intake. BOV, and TMIC. Not sure if it helps, but it seems to be the reason for us.

[boosz]

By intake, are your referring to the cold air intake?

[MAZOOM]

Yeah, and 20L per 100km is awful.

As you can see in my sig, I can average a healthy 20mpg if I don't drive it with Zoom Zoom.

[boosz]

Yes... 20 per 100 defies description... Imagine my response to the service writer at the dealership the first time it went back for this.... he actually was SHOCKED that I was complaining about getting this kind of mileage and that "HIS CX7 gets the same mileage so what would I like him to do about it!!!????!!!! " My response as I threw my keys at him was FIX it or take the F'n piece of S' back... Incredulously his smug response... "I'm not authorized to do that" I was NOT impressed, seeing as I had just spent $40 thousand on a car that gets worse fuel mileage than big block carbureted cars I drove as a teenager!! I wanted to choke the chubby little twerp!!

[Raider]

By intake, are your referring to the cold air intake?

Yup. We have the CPE intake. Had it for over a year.

[boosz]

Can you hear alot of turbine wind up with the intake? I don't think she'll appreciate that kind of sound!! Us guys on the other hand..... :)

[MAZOOM]

Yeah you can hear the turbo whine everytime it's past 2000rpm, thats when boost onset starts. Music easily drowns out the noise.

[Raider]

You can, but considering our CX-7 is my wife's daily, she loves it. You will hear more air getting sucked in My mother in law calls it the airplane, as it sounds like one when we take off from a light. It is up to you, ultimately. You might not get better mileage, either, as you have AWD. But who knows.

[boosz]

After doing the injjector flush, it was down to 13 per 100.... But it was only just done, so I'm monitoring the mileage... 13 per 100 I can live with. It's much closer to advertised, than what it was getting! Yes music DOES drown out most noises. With two teenage daughters, the music is rarely NOT drowning out everything, including speech!! LOVE the Bose system!!

[islandcx7]

using 91 octane and getting 15L/100km, still have winter tires on, but don't think that will make a huge difference, would love to get 13!!!!

[boosz]

I've been using 91 sometimes 94, and just the factory all seasons. The 13 per 100 was straight Highway minus the couple of km that were city getting too and from the highway. So.... I'm still monitoring. Will post more to see if the mileage stays consistant around the 13 mark.

[Crash]

I usually am getting 12.5 per 100km's on highway driving....I keep it at 120....I need to now that they got that new plane in the GTA that looks for speeders!

[boosz]

Yes I agreen Crash...... I do alot of riding and the 407 was always one of my fav's to run fast..... That's me on my lil rocket in my avatar.... but I'm off topic now....

[Brad]

I was quite impressed with the mileage this past weekend. I got 8.7L / 100 on a trip to London this weekend. Stayed at 110 on the 401.

[islandcx7]

are you driving AWD or FWD? That's pretty impressive either way!!

[MAZOOM]

Fwd
.

[Crash]

wow...that's awesome. I'm averaging 12.5 per 100k while doing 110-120 on the 401...unfortunately I'm going from Guelph to Toronto...a much crappier drive.

[leshii]

wow! I'm reading this and can't believe what I'm seeing. I have an '08 AWD GT w/ engine under 2500k km (it's a little over now actually) and I getting under 11L/100km highway @ 120 km/h on 401 and 14L/100KM on short trips in the city.

[Bergag]

I have an AWD and averaging 12.5/13 in city and recently did 10.1 L/100km on an highway trip in Quebec with speed lock at 105 on cruise control. I have to say that i have to prevent to push the engine too much to get those number, as soon as you Zoom-Zoom it will affect the mileage really bad.

[shinch]

I have been using Premium 92 and Husky's 94 octane when i can (my work pays for ALL of my gas, so price is not a factor). I usually get around 15-17L/100km. But when you are not paying for the gas and the car is leased = ZOOM ZOOM ZOOM! (now if only i can get them to pay for my tires...).

I am getting my engine flushed next week, so it will be interesting to see if there is any difference.

[leshii]

Drove 550km yesterday. 10% bumper-to-bumper, 15% normal city traffic and 75% highway 401 at an average of 75mph, 30% of the way with A/C. Still no 'low fuel' light.

[shinch]

AC using gas - i have heard this a lot and have a sister that employs the on/off strategy to save gas.
Cosumer Reports did a test on AC and as well on increase drag from driving with your windows open. They used a vehicle with very low torque as they felt the difference would be felt more - an Echo i beleive (probably because it is the car of choice for nerds).
The increase in fuel consumption with the use of AC was 1% and driving with your windows down 0.5%. Obviously there are bigger things we could do to lessen the fuel consumption, i.e. let the car beside you win the green light race, drive only 10% above posted speed limits etc. (But where would the fun be in all of that)

I will try find the article, but i beleive it commented on new AC systems vs old and how new ones have less impact.

Just fueled up today. Exactly 60L for 565km which equals 10.6L/100km or 22.3mpg. Not too shabby with that breakdown! Especially, since it's an AWD GT + bose and 205lb driver :)

[LuckySeven]

um can I post this here?

Last tank:

93 premium
AC on 95% of the time
city driving
got on it once or twice
sport fwd

343 mi. Thats about 19 mpg, so I guess its getting better.

[Crash]

Did the light come on? Those are decent results for the driving you'd done

[LuckySeven]

Yea it came on. I continued to run it til it hit the E line.

[ilovecoffee]

Yikes. First post here. Seriously considering the CX-7 over the VW Tiguan. Everyone seems to be posting mileages all over the place. 20L/100 is pretty...unimaginable, and I have a heavy foot as it is (mind you, I have to in my current little Toyota Matrix).

So where is Mazda really getting these advertised figures from?

[MAZOOM]

20L/100 is not typical.
However, getting AWD, city MPG will suffer the most over FWD as it would in the Tiguan.

You have to drive "safely" to get advertised MPG or better. I'm one of those that get better MPG than advertised (15mpg city, I get 17-18 as of recently). is US mpg figures. I have AWD and it really depends on how you drive it. Bringing it over 4K rpm will murder the MPG down to 15.

[MattAveli]

I got 504 before i was scard to go any farther on my first tank shell v power plus k&n dropin. I drive pretty light footed. There is 80k on my 07, so I guess I'll concider my self lucky. Oh and that was 1/2 city and 1/2 highway. Anybody concider those octaine boosters?

So where is Mazda really getting these advertised figures from?

The big thing I learned is I had to "learn" how to drive the turbo. It kicks in after 2500 RPM's (which IMHO is too low)...keep the needle south of that and you'll be fine....I do about 70% highway driving (07 GT AWD) and average about 10.5-11 lt/100km (going no more then 120 km's per hour). Last week I absolutely drove my Mazda like it was stolen and I got about 13 lt per 100 km's.

Also - when filling the 7 at the pump - you'll notice the hoze clicks off meaning it's full...it isn't - you're good for another 10 ltr's. I say this because if you don't fill to the top - you'll be shocked at how quickly the gas needle drops - and you'll get well below 450km's on a tank (I'm getting about 550-600).

[leshii]

I drove through the states the other day and I got about 10.56L/100km doing about 122kph on cruise.

[MattAveli]

i love how long it stays above full when you fill her till she pukes...lol

[Crash]

I always find that when filling after the nozzle clicks off automatically, my 7 is good for another 6 litres of fuel. The weird thing is that I find a litre per 100km improves drastically. Bizarre.
