Genpu Smoke
 

Hey guys.....Just curious if anyone has noticed smoke on acceleration at part or wide open throttle in a 2010. Noticed a little today. I'm not concerned, but I am wondering if anyone else has noted it. Mine is stock with about 1,600 on the odometer.

yessssssssssssssssssssssssssss
fail is imminent!

Good stuff....fuck it. I'll worry about it when it lets go

straight up, it could just be soot...
are we talking about constant smoke for a few seconds?
or just like a quick pop from the tail pipe?

No need to worry.

2010's don't blow.

Are you talking about light colored smoke or dark smoke? Even stock my car put out black smoke at WOT. Now it REALLY dumps it out haha.

It's not excessive. Most noticeable in 1st (highest load) and during the 1-2 shift. Although, the soot has become more noticeable over time.

I'm not worried, but I am curious if anyone else has noticed it on their 2010.......Fuck the environment

BTW....it's white smoke, not overfueling

white smoke?
how's coolant level?

The coolant level is fine (at MAX) and there are no bubbles in the degas bottle. We've had a fair amount of rain lately. It may be condensation burning off. I'll keep an eye on it.

My problem is, I don't want the morons at the dealer touching the car if this is in fact the beginning of a failure.

change the shitty dealer oil already. beat on it a couple more times for 100 miles drive it normally for another 100 and dump the oil :)

Wait it out and see, you do have a warranty (if you can cover up mods good)

1st is t3h lowest load.

Have someone drive behind you and tell you what it smells like. I've had smoke like that since day 1.. and now there's even more after my DP install, lol. It's just fuel. I'm told I smell like a race car behind me now when I take off..

And if you notice any other car on the road, if you see smoke come out of their tailpipe that means they just gunned it.. I started to notice that more.. Most cars either have smoke coming out of 'em or they just all of a sudden smell like fuel behind 'em, it's because they just got on the gas hard.. It's funny because I'm driving normally and see people do that and it's like well.. I'm keeping up with you just fine with normal driving and they're going hard.. lol.

^^ you are correct. What I meant is that I generally do not go WOT past 1st because most of the streets I drive on are residential. Hence, less throttle plate opening and less load. I gotcha.

I'll change the oil and give her a go, see what happens.

ms3brendan....you are correct. When the throttle plate position opens quickly (someone stabs the throttle), the load increases and the PCM overfuels in order to help prevent detonation. However, when the throttle closes during the 1-2 shift after light acceleration (as in my case), the module has no need to spray more fuel to compensate. Although, these engines run rich overall.

Just FYI-- did the first oil change this weekend and the smoke cleared up. I made the switch to Pennzoil Platinum 5W30 (On sale at O'Reilly for $3.99/qt). This may be of some interest that the typical VCT phaser rattle on cold start has diminished significantly. We'll see how it does over the course of the next months.

I've been noticing some nice light colored smoke trails when I bury the throttle in 3rd gear or higher, typically at 45+ or highway merging attempts. I can see the smoke in the path behind me or in the path of the headlights at night.

I've checked the oil level and it's full, but it's definitely not a dark brown color. It's literally a grayish color. I'm hoping this will all change when I change the oil at 1500. Possibly just the "break-in" solution bullshit that is seeping past the seals, or the fact the car has run filthy-pig-rich and is finally burning some of that shit off.

Hmm... I definitely smoke at WOT, but I didn't of the type of oil having to do with it. Let me know if you get anymore with Pennzoil! I've been using the shitty dealer oil for 12k miles...

My car has done this from 14miles - ~600miles I have on it now. It's really noticeable at night when you gun it in front of someone's headlights. Judging by the condition of my tailpipes (hell, the whole back of the fucking car), it's just a result of this car running the most godawful pig ass rich of any car I've ever owned. I doubt it's oil.

just for the record


soot has nothing to do with oil....lol

Soot=fuel

.

That's what I thought but I didn't wanna sound like a nub.

So you guys are changing out your oil right off the bat? I'm waiting till 3000 for the first oil change - then penzoil platinum every 3k from there on out.

Although I gotta find a place to take my car to get the oil changed just so I can have receipts in case I need warranty work done.

Yeah that smoke may be related to oil.

Had the same issue 1 day after I took delivery of my car. Prior to delivery I asked them to renew oil since my suspiciton was that the car may have stand on their lot for more than 3 months.

So when I was pooling I was able to see some dark smoke. However that smoke is different from what you have on a turbo leak (had the turbo issue on my 2007 CX-7 so I knew the color of the some).

I took the car back to the dealer ship and I doubled checked this time that they put the oil Mazda recommend for the speed3 and after this that smoking was gone.

As I said earlier it may be related to the oil (type and how many miles since last oil change) the dealership or you guys are using.

Our new babies shouldn't be smoking.

Men have it done at the dealership. It's pretty much the same price as you buying the oil to the dealership. Don't know for how much you guys buy that oil at autozone or wallmart. I made the math if you buy it at the dealership may be $5-8 more they are charging for oil change.

One think you guys should do when you take your car out to service is to check that:

1) Take a knife and go on the oil filter. Scratch it and put some mark there. Request the dealership to give you back the old oil filter and the empty oil bottles they used (if they used synthetic then much better).

2) Before taking back your car and sign off on any work done, please make sure to read the DEALER RECEIPT of the work that have been done on your car, BUT NOT THE CUSTOMER RECEIPT. On the dealer receipt they record all the work for their own documentation and what was exactly done on your car. What the customer receipt won't always reflect.

So don't just trust the dealership to put you the oil Mazda recommended in your car. They tried to save on every corner.

If I could get the oil (synthetic) 10 -15 bucks cheaper that what the dealership is charging I'll be doing the oil change on my speed3 my self. First because of the short interval (3000 miles, saving more on the long term) and secondly because of the easy oil filter swap on the speed3 (different on the CX-7 models who use cartridges)

I do all oil changes myself (only exception was the S4 I had before this because it held 9.5 quarts and the drain plug was like 2" in diameter so it was just impossible to drain with out making a lake), and I intend to do the first change at 1500 and then every 3000-5000 after that depending on analysis results.

My car arrived at the dealer only a few day before I bought it so I'm not too worried about it.

Also, yes, the soot and smoke is obviously fuel. I'm not sure why anyone would have thought otherwise. To smoke under WOT and have it be oil, you have to have some pretty serious oil ring wear.

I just noticed my car now blows dark smoke at WOT. Hmmmm, I hope it is just from running rich.

How come fuel will make it smoke? I'm not getting your point here

If you've ever had the opportunity to tune a car, setting it rich will absolutely produce shitloads of blackish smoke. This is simply residual carbon and unburned hydrocarbons as a result of there not being enough oxygen to ensure complete (or at least better) combustion.

Blown seals typically produce a white, thicker smoke.

Unburnt fuel/rich fuel or carbon will typically produce a darker, black smoke.

why is this thread back again? Smoke is white soot is black ... soot = rich which the car is stock.

my car has "smoked" at WOT from day 1. changing the oil does not help. don't let that fool you. it will not go away. the car runs rich...just something you have to live with. i now have 15K miles on the car and it "smokes" just the same as it has from day 1. in case you are wondering, i changed out the factory oil at 1200 miles and do a syn oil change every 3K.

yes, it does seem excessive at times, but mazda did it for a reason. reduction of warranty claims and engine self-preservation.

I'm going to ask if there are any revised flashes available when I get the oil changed.

I'm not getting your point with the smoke and the reduction of warranty claims.

its not smoke ... mazda has the car tuned rich because its safer thats why you see the carbon at WOT ... safer for the engine, hopefully less Zoom Zoom Boom that is all

so a blueish grayish smoke under wide open throttle is what?? I know this is when MCI put Amsoil 15w/40 heavy duty diesel and marine oil synthetic in and this cured the problem. Were my turbo seals going as at idle was not smoking? any how there is a new TSB out and it is a PCV upgrade for climates that don't have freezing, and where temps drop below freezing you get a NEW TURBO!!!!!! I will be having a new Turbo put in once dealer gets it. I believe all 2011 2.3 disi turbo equipped cars will come with this new redesigned Garret turbo with single oil feed Hence no 2011 Speed in Canada or CX-7 with Disi as the PCV upgrade is no good for cold climate due to freezing!!!

You just make this shit up, don't you?

Was it worth $10 to straight up lie to people about what's gonna happen for future model years?

Ok it's called information buddy and as stated on here before there is a PCV upgrade for $25? The TSB that is applicable to northern cars is the new turbo and possibly a different PCV design for southern cars! I will post pics of new turbo and old turbo and post MCI authorized amsoil 15w/40 syn oil change once my work gets done! You guys groaning at me are a bunch of bone heads!! If you have a smoking issue contact your dealer about new TSB!

Thats not my 2cents its fact!!

I read some threads in here and I want to bash my head against a wall. It is so comical how people are with cars. It is a turbo car and yes, smoke will come out of the exhaust or "soot" as some cal it. Happens all the time especially when shifting in higher rpms. Just drive the damn thing and stop worrying!!! If smoke, brake dust, or any of those little things bother you as you are driving a "performance car". Go cry in the corner. The wipe your nose, head over to your local Honda dealer and trade your car in for a civic hybrid.

Where you're not getting the point is, usually smoke is a BAD thing, especially on a brand new car. It's not a Diesel and it's not modded, so it shouldn't be smoking. Now, is it bothering me? No. Is it a slight concern that our brand new cars like to huff a bit? Yes, it's a "slight" concern. But it certainly doesn't stop me from putting my foot down.

If you hate these threads, why did you need to come in and "school us" on our overly dramatic sense of urgency towards our "high performance turbo cars"? Bless us with your knowledge then as to why smoke or "soot" is considered normal in your book. Smoke out of the exhaust pipe is usually a bad thing, all things considered. And no, this isn't my first time around the block with a MS3, and no, my 1st gen never, EVER smoked (modded or stock).

So you're saying that mazda produced a car with a known issue (smoking turbo) for 4 years without changing a single thing about the engine, save for possibly the pcv system (and I haven't seen a single photo yet to confirm that it's "improved"), and then all of the sudden they get all generous on us and start giving out new turbos?

You better post a photo of the tsb, with the invoice for the new turbo, with the new turbo. Until then, you're full of shit as far as I'm concerned. While you're at it, a signed letter from the service manager at the dealership you're getting this from confirming that what you're saying isn't complete, unadulterated horse shit wouldn't hurt.

If you can do that, I'll take back what I've said, but until then you're simply a straight liar in my book.

Every car ive seen go WOT on the highway shoots out a cloud of unburnt fuel...
