Great. Rev between upshift, between downshift, and now before shutting down even though the car is already warmed up. It is the little odd behaviors like these that serve to separate yourself from the new school rx8: 06 - 08 in AT trim all female drivers.

On cold shutdown, a slight modification is to hold 3000 rpm for 10 seconds, then hit 6000 momentarily. Let the rpm drop until it bottoms out causing the shifter to vibrate, then shut down. I wait for that little dip at the bottom of the idle range, and it vibrates to let me know it is ready to go to sleep.

I'm also keeping the exterior dirty now to stay more old school rx8.

The premix was a great idea. It takes me a long time to dose out 4 oz of this and 1 oz of that before I even touch the gas pump, which sometimes causes a slight backup of waiting vehicles.

Every little eccentric behavior has a dual-purpose.

^ That's the only reason I'm not really Premixing at this second. 1.) I wouldn't know how to measure it out. 2.) The time. By the time I hit 10k miles, though, I'll be premixing.

Bamablocker

so after you rev it, you turn it directly off before the needle hits zero?

Bamablocker

what do you premix, just got mine so bear with me.

CyberPitz

I rev it then turn it off if I do that, and as for what premix, there are a million threads. If you search, you will find the answer.

luv4eternity

exactly ....from what i learned from a friend that knows about it ...he says that u rev it at least above 3k miles and then turn it off QUICKLY....that will burn the left over carbon that is in the engine and kinda prevents flooding(according to him).....i've been doing it and it seems easier to start the car next time too...

JRichter

So do I look like a ricer before pulling out of a parking spot on cold mornings because my car automatically revs up between 1500 to 2500 rpm's? Or is that only for pulling in to a spot? Whenever my car does this, I aways look around and imagine people thinking Why the hell is he revving his car up like that while it's cold? I've noticed even when you pull off while it is still doing this the car will accelerate as if you are giving it throttle or when you press the clutch in the revs shoot right back up to where they were.

dmc27

It's recommended as flood protection, but MySQL is right - it's not a fool-proof "you're engine will not flood if you do this" method. Also right that it does nothing for carbon. It helps prevent a rich fuel build up that could flood your engine at the next start up attempt.


Who said "not premixing b/c I can't measure out the amount" ???? lol.

Just go to a beauty supply store and buy one of the little plastic containers they sell for hair dye. Ask your GF/wife/sister or something, they will know where you can find it. There are several different sizes ranging from 4oz to 16oz, conviently marked as such, and it has a little spout that makes it nice and easy to get into the tank. (I cut an inch or so off the spout b/c they are not made to be high flow containers)


Oh, and search n00bs.

Before everyone gets off the real topic here. My question was did anyone hear that you should rev the engine to 5k before shutting off the car no matter what condition warm or cold

dmc27

Yes. Most have been told that by a salesman, service rep, or other Mazda rep.

And a handful of us have read the manual and found it there.

I have owned my RX8 since 2003 and this was the first time a heard the mazda dealer say you should rev the engine before shutting it off

CyberPitz

Lol, blame me for being a lazy slob ATM. I don't have anything, literally, to help me measure out liquids, especially to pour into a car!

Bamablocker

maybe you can do it at home, just when you go to fill up carry it with you, instead of doing it at the pump. know what i mean?

Socket7

I will blip the throttle when the engine is cold before shutting it off. Never when it's warm. It's not needed. I have NEVER heard from anyone to rev it up to 5K before turning it off.

I don't think it would cause any harm though.

Racer516

I never try to REV before shutting down. I do bring the car to redline on a regular basis. I think of my engine like a turbo. You don't want it spinning fast after you shut it off.
I would love to hear from someone that really knows our engine.The one and only time I had an issue with slow start was when I was rushing to a meeting and shut the car off in haste, hi rev, it was slow to turn over when i got back out.
My thought is that fuel gets in the engine as it continues to spin and doesn't burn since the ignition is off. When you go to start again the fuel is pooled in the engine and is flooded/hard to start.
Does the fuel get cut with the ignition and by letting it spin it all just gets pushed out? I just don't like to hear the engine still spinning and see no oil pressure.

i only do it when im about to shut off my car and its not warmed up. everytime seems a bit rediculous if you ask me.

Socket7

Injectors would turn off the moment the ignition is turned off. Any excess fuel from them should theoretically be sucked through by the engine's own vacuum and be pushed out into your exhaust.

Where it will clog your cat instead of flooding your engine.

I'd have to also learn conversions for gallons -> Ounces. Like I said, Lazy..

Ok, here is a question for you chumps.
Do we rev, keep it in rev, turn off the car, and punch the gas pedal?
OR
Do we rev, keep it in rev, turn off the car, and let go of the gas pedal?

I've been shutting off the car and punching the gas while in rev... I don't know if this is the proper procedure or not.

Socket7

I rev, let go of the gas, and kill the ignition as it starts to spin down.

Spinning Sushi

I use to do that until I notice Yoshiya (Owner of Neptune Speed) stepped on the gas after he shut off the car while in rev. So my question: Which method is better?

P.S. It makes a cool intake suction noise when punching it after turning off the car while in rev.

Soapflake

I only do the 10 second rev when I move the car cold and thats rare. I never rev before shutting off when its warm. Only had the car for about 5, almost 6 months and haven't had any problems with flooding. What benefits do you get by doing a 10 second rev every shut down?

mysql

That doesn't mean squat though. I had the car for around 3 years before it flooded.

bxb40

If cold outside, I rev to 4-5000 after parking, let off the accelerator and turn it off about the same time. I never had to shut the engine off when not fully warmed, so cannot comment on the usage to prevent flooding. The injectors and accelerator are electrical, so when the key is off, those are off too (hence useless to push the pedal after the engine is off - on RX8 at least). The oil pump is mechanical, hence it does not care about ignition off or not - lubrication and oil pressure depends on RPM, no issues to rev when engine is off. If thinking of the oil metering pump - it rarely injects oil anyway, so it does not matter.
Does it help anything? Probably not, but it cannot hurt either, so I consider this "prevention." Just like premix and many other quirks learned since owning the RX8 for 4 years... Don't care what people think - if the car needs it, the car gets it :o) But that's just me.
