View Full Version : Gas Mileage Thread for Mazdaspeed3
I know most of you didn't buy this car to be fuel efficient. :chuckle But watching gas price nowadays I can't help to think about the gas mileage.
First two tank during break in I've got about 370km out of full tank. After the break in, the gas mileage increased significantly to about 450km average out of full tank.
I've been using Esso, on the last tank I almost got 500km (9.3L/100km using majic's sheet) on a tank.
I've been noticing very mild pinging when the rpm is decreasing from about 2500 to 1000. I usually notice it at 1500 to 1100. The exhaust produces sort of like double pop. Pinging is the right terminology here right? I decided to use Sunoco 94 octane. I'm just first 1/4 of the tank so I'll see if there is any change. But oh boy, Sunoco's gas does burn lot faster. :chuckle Perhaps this is not related to gas octane?
BTW, my average consumption on meter says 8.9. :bana

Note that Esso has been charging 89 octane prices for the 91 lately. I thought it might have been a fluke the first time, but it's been like 4 fill-ups in a row now!
My average consumption as of my last fill-up was 10.01 L/100 km's.
384.831L for 3844.3 km's.

I think its pretty awesome if you can get 450-500+ km per tank, considering the power these engines are producing.A question for you though, Why use the 94 Octane? I don't believe it asks for that! ....using a higher octane will most likely not proof beneficial especially gas mileage wise.You should stick to what it calls for nothing more.
Also I believe the popping you are hearing is not 'pinging' it is called 'back-firing'.Pinking is when the engine is under load (increasing revs) and it sounds like marbles floating around in the engine, what you hear most times when revs are dropping is unburned fuel entering the exhaust which then ignites causing the 'pops', ....its normal.

Because I've recently started hear this noise from the exhaust. It used to be very uniform. I was wondering if it was the gas, that's why I've switched to 94 see if it makes a difference.

Well going to a higher octane will not cure it! It'll most definitely make it worse as less fuel will be burnt properly.You should stick to the proper grade and try different fuels i.e such as Shell or Petro. IMO Shell is the best quality fuel out there.

Given this thread is in the mazdaspeed section that is kinda what the conversation is about :) ... i agree that premium for all cars isn't worth it, but with turbo/super charged cars, higher compression engines you can't go wrong with the higher grade.

We are talking specifically here about the MazdaSpeed3, nothing else.Now my point is whatever grade Mazda recommends people use and I'm not sure, so correct me if I'm wrong, but I believe its 92 octane which is recommended.Therefore no higher should be used has it will show no benefits and could possibly be a detriment in several ways.(Unless of course alterations have been made which would warrant an increase in the octane-count)

Premium unleaded fuel 91 [ (R+M)/2 method] or above (96 RON or above)
This vehicle is designed for and requires use of premium unleaded fuel. If 91 octane fuel [(R+M)/2 method] (96RON) is not available, gasoline as low as 87 octane [ (R+M)/2 method] (91RON) can be used temporarily for emergency purposes. Use of gasoline lower than 91 octane [ (R+M)/2 method] (96RON) can decrease performance during its use.
Refueling the vehicle with the correct octane fuel a couple of times will restore vehicle performance.

If I'm not mistaken, I think that if you continue to use 94 over time, this engine will adapt and make use of it.
There was something on the M3F forums about this.
That said, I only use 91. If there's a tad more power with 94, I don't think it's worth the extra money to me or effort to find. :)
As for posting what the computer says... I've found it to be inaccurate over a few tanks now. On my last tank, the computer said 9.3 but I calculated 10.1. On the tank before that, the computer said 7.3 and I calculated 8.34
Maybe I should stop resetting the computer at each tank and just see where it averages out over time.

Won't affect my average, but it sould change the individual tank readings and make them more consistant.

First of all thanks for posting the info from the manual. ...but I get a different meaning from it than you.I see it has 91 is the grade you specifically should use and above is okay to use also, it is not better, it is just okay to use if 91 is not available.You have to understand that the vehicle is designed to run on 91 (Compression, timing etc;) and if you use a higher octane fuel regularly you do run the risk of fouling the engine and increasing carbon build-up.On the other hand as the engines get much older and carbon build up has already occurred which will happen normaly a higher octane may be neccessary to eliminate any pinging.Mind you all engines and driving enviroments are not identical, so it is a hit and miss thing where you can experiment to see which fuel does run better in your specific vehicle i.e power vs cleanliness...I am also curious whether Mazda took into account the ethanol contents in fuel as it is different in all brands of fuel and grades.

six and a half a dozen the other... if it's worded in a way to interpet 91 or above as 91 or above than I doubt you'll be harming the engine.
Guess the only way to know is to tear our engines down in a few 100,000k's
Wild Weasel
06-05-2007, 07:44 PM
That's assuming that the engine was designed with 91 octane in mind.
It's possible that it was designed with 94 octane in mind and simply learns it's operating parameters over time, figuring out how much timing it needs to pull to prevent knock.
This is purely speculation though. For normal engines, I wouldn't dream of suggesting this but for such a high performance forced induction engine, it wouldn't surprise me.
Damn reflection, but the needle is pointing the half way mark.

If you keep the engine out of boost (lower than ~3k rpm) you can get really good fuel economy out of the car. I have a speed 6 and have achieved ~7.9L/100km (708km on 56L of gas, all highway mileage averaging 115km/h). I would imagine that the speed3 would be able to do even better with its lighter weight.
Having said that, my worst tank of gas was 17.5L/100km (325km on 57L of gas - winter time city driving with lots of parking lot fun).

around 110km is about 2800rpm where the boost builds in and kills economy... if you can stay below that speed and not dip into the boost to heavily you should have no problem getting over 600km

I went to the auto show in Detroit last weekend. Normally for those sorts of trips, I drive around 110 - 115 with the cruise on. I easily get over 600 kms.
Last weekend however, we got delayed leaving the city so I was in more of a hurry. I probably averaged around 125 for the trip and got well under 500 km's on the tank. I expected it to be less, but was surprised at how low it ended up being!

At the Shannonville race track for a lapping day, I got 88 km on 40 litres in the morning and and 105km on 50 litres in the afternoon. Boost kills gas! Daily my computer reads 8.8L/100km but the pump says 10L/100km averaging 500km per tank (I run it dry!). The only explanation is that I leave the car idling for 20 seconds to cool down the turbo and the computer does not take that into consideration I guess?

When I drive in the city, I never let the tank go below 1/2 but generally the computer tells me I'm using 12.5-13L/100km 100% city driving. For Christmas vacation I drove out 13 hours to my fiancee's place in Quebec. I got 685km out of one tank, averaged 7.6L/100km that tank, 100% highway, which is what the fuel estimates are for my car. I had the cruise control at 110km/h the whole time, didn't have to brake or stop for a break once. That works out to 52L of fuel used. Sounds right. I think that fill up said 51.5L on the receipt. The tank in the MS3 holds 55L, correct?

If you're measuring your economy, just fill it until the pump clicks off and keep track of how many km's you get and how much gas you needed to fill it back up.

lol...I can sense the tone of doubt in your question...and I echo it by asserting that it's likely mostly hwy...
as hard as I've tried, I have never been able to get 500km out of the tank...I might have touched it once on a 1-stop run up to Ottawa, but now I just give up...I drive like I'm always late...then of course I show up 10 min early... ;)
and yeah, I've used up a tank of gas at the track in about 100km...funny thing is bigger tracks aren't that much worse on gas and definitely much better on your tires...
since the weather got nice and I've been testing, I have avg'd 13 - 14L/100km at times...normal D2D driving (I live in downtown TO) I get ~11L/100km
Well I do get 10.3L/100KM from about 60% highway 40% city driving.
I know 10.3 is pretty accurate because I keep history of the date, mileage and litres of gas I pump in.
But going down to 8 or 9L per 100KM is when you drive 70% or more highway of your driving.
(Or maybe economy mode with Cobb AP)
I get about 470~500KM per tank and I do push it time to time.
~450km full tank 100% local driving.

On my commute to work when I don't rip it(which is quite often) I get high 7s/100km or around 8L/100km Last tank I filled up 41.45 liter and drove 530km. The trip computer says 30.4 mpg = 7.73 indicated. But I calculated it as 7.8xL/100km.
On weeks I go out more and do a bit more city /traffic driving, going out with friends, lots of stop & starts. My average usually drops to mid to high 8L/100km.
This is 100% stock car, dino oil, stock airbox, heavy 18s.
I'm sure if I get rid of the stock airbox, 18s & dino oil I can average low 7/100km.
I remember when I first got the car with 200miles and March weather, it was averaging a little over 10L/100km. My fuel compsumtion loves summer heat!

I don't know why people find it so hard to get good mileage in their MS3. Maybe I'm just lucky. I average 9.6-10L/100km in 100% city, 5:30pm traffic. computer usually says 9-9.2L, but I work it out when I fill up. If I stay at 100km/h on the highways, with 100% highway driving I can hit 6.8-6.9L/100km. Most I've ever gotten from a full tank on 100% highway was 660km till the fill light first came on. I drove another 5kms to the next gas station.
And don't get me wrong, I accelerate fast whenever I can, I just don't speed or hit the gas hard to get around people.

If I stay at 100km/h on the highways, with 100% highway driving I can hit 6.8-6.9L/100km. Most I've ever gotten from a full tank on 100% highway was 660km till the fill light first came on. I drove another 5kms to the next gas station.
And don't get me wrong, I accelerate fast whenever I can, I just don't speed or hit the gas hard to get around people.
Come on AL, we all know you have a little Granny hiding inside of you!...j/k :chuckle
but seriously, when does the boost start coming in, what rpm? ....and does it come in @ 15psi all at once or is it gradual?...just curious!

it starts boosting a little in high high 1000rpm or about 2000rpm, if I floor it at 1500rpm in high gear, I can feel it get a bit of an extra kick just slightly under 2000rpm, then at around 2500rpm the boost increase sharpy and by 3000 I believe its full boost... or full torque at least, don't have a boost gauge I have no clue waht psi its running but full torque is avaliable around 3000rpm and i'm guessing thats full boost.

First two gears boost is limited. One time I tested when I got boost, put it in 6th at ~1250rpm and put the gas to the floor. Started spooling around 1700rpm and by 2200rpm it was at full. When I accelerate in traffic though, I normally shift very easy on the gas at 2000rpm most times. The odd time flat to the floor shifing at 3000-3500.

My last full calculation yielded that I was doing 9.5L/100KM (despite what my computer was telling me)
That's a combo of highway, mild city and some spirited driving.
Any extra costs incured for gas on this car... I consider a "smile tax"... this car makes me smile when I drive it.. every day.

I got about 680km on a trip in the US and the light hadn't come on yet. Wasn't about to pull a "Kramer" to see how far I could go into the red while travelling in Chicago!!
In the city, I like accelerating too much, soooo, my mileage drops signifcantly to around 420-450/tank :blush

The problem with my one time letting get to the fill light on a road trip, I hate letting it get that low. I normally get 580-600kms or so with a 1/4 tank left when I fill. That tank I let it go down, I was at the 5 hour stretch between Quebec City and Baie-Comeau, out in the middle of nowhere where large, steep, and long hills are abundant. This point of the trip is usually between 2am to 7am...no one on the road = fun.

Your car is spoiled! No 94 for me on my journeys to Quebec. I'm lucky if I find 91, I've stopped at a few places with only 87 pumps and had to keep going. Now I always stop at exit #2 just over the Quebec border and exit #291 just before exit #312 to Quebec City. Those three full tanks gets me to my fiance's place.
The odd time I'll fill with 94, and even though it's only 2 cents more a litre than 91, I always ask myself if it is really worth it. I've done three solid tanks of 94 then gone back to my normal Shell 91, and I honestly can't tell a difference, if there is any. I don't think the car cares too much.

My RX8 wasn't too bad. I loved lapping it, which is eventually what did it in. I boguht a house and needed something a bit more practical so I got the MS3.
On the track my RX8 would use about 35L/100km, and drink about .75L of oil a day. I ran stock discs with mazdaspeed pads and I would get about 3 track days to a set of discs, and 1 summer to a set of pads. I also used a set of T1R's a summer.
The big thing is ignition components because the coils/plugs/wires are mounted on teh side of the motor with limited airflow. I would go through a set of plugs/wires/coils every summer.

Weird that I havent once seen my tank go over 330km, but im going in next week for a fuel consumption test.

I'm impressed lmao... I like that idea for the thread better. No way I could beat 3 hours... I think my fastest tank was 12 hours of pure driving, to and from my friend's cottage.
If you drive at 100kph you should be able to burn through a tank in less than 5 hours without even trying
Just sayin, 100kph for 5 hours is 500km. If you are getting 400km per tank then thats 4 hours of driving

What is with everyone quoting how far they go per tank? That is NOT how you state fuel economy, and it means absolutely nothing.
Tank size variations, fuel gauge accuracy, temperature and how willing you are to be stranded and out of gas in the middle of the winter play will change your "numbers" by like 100km.... which when you're quoting numbers as low as 300 is very significant.
Quit being lazy and do the math.
I'm getting 8.0L/100km now that it is winter, in the summer I have gotten 6.8.

No, but it takes all of 2 seconds to do the calculation and give an actual number that means something.
Lets say the Gen2 tank holds an extra 5L over the Gen1 (that would be an extra 50km). The guy with the gen1 gasses up when his light comes on and the guy with the gen2 drives another 50km, even if they both drove the exact same way, and the exact same amount of highway vs city, one would always get 600/tank and the other would always get 500km/tank. That is nearly a 20% difference which is MASSIVE when you're talking about fuel economy. I.e. the numbers you all are quoting are goddamn meaningless. I work in the aviation industry, and manufacturers get excited when they develop something new that can save 1% on fuel economy.

This isn't aviation and it definitely isn't rocket science
When someone who drives a speed3 says they're getting 450kms a tank we know what they mean if you know they have a gen1 or gen2
You could also drive 100kms at some stupid speed under great conditions and get a great L/kms
For example your 6.8l/100kms doesn't mean shit to me and shouldn't persuade someone to buy a speed3 for fuel economy reasons

Right, but the point is that it is possible to get decent mileage from a speed3 if you drive economically. Some people think that it guzzles premium gas like crazy... it does, but only if you drive it hard.

I was getting almost as bad. Checked my air filter and tire pressure. They were fine. Changed the spark plugs. No improvement. Think the throttle body is on it's way out, but can't think of why that would cause such bad mileage.
If I look at my mileage for all my fill-ups From Oct to Dec of 07, it's an average of 10.15 L/100km. 08: 11.52. 09: 10.96. 10: 10.90. 11: 11.96. 12: 11.83. 13: 13.64, 14: 13.79.
I used to be able to get well over 600km on the highway. Coming back from Detroit a week ago I got just over 400 when the light came on.

I'm getting anywhere from 350-400 with 400 being when I can hit the highway for at least half of just under the amount tank. I'm basically stock with no resonators and a CAI. AP running stage 1 SF map. I only use 94 from petro Canada.
Wasting money with 94 if not tuned for it.

Is at least the Stage 1 + SF 93 Octane map?

Has anyone ever run the Eco map on their AP, and does it make a difference?

I'm sure it makes a difference, I'm just not sure why anyone would run that map

not necessarily, but as far as I'm concerned, my fuel economy as well as my cruise control are both operated by the same device; My right foot.
