but is the original just pure coolant? cause i accidentally open the cap while it was still hot and some coolant spill out...ok not some....alot. I dunno if I should replace with pure coolant or mix.

I think it comes premix from the factory with coolant and anti-freeze. Anit-freeze is really useful , when it snows. Otherwise it limits the heat transfer and heat capacity. Not by much but good can always be better.
Btw, if it was true that mazda discourages synthetic, it may be because some synthetic (because of its unique formulation) may cause problems. So they might discourage against all synthetic rather than a particular few.
Or maybe one engineer disagrees with another engineer. Or one department got wrong info, etc, etc.
Bottomline is, i feel synthetics are ok.

I'm really new to this car. I have just bought my 8 and i observe that at the front of my bumper at the passenger side there is a black cooler thingy looks like an oil cooler but at the same time it looks like an ATF Cooler.
Can you kindly enlighten me wats that
As for the 06 model AT there is still no 6 speed thingy cause i'm currently driving one which is manufactured in Feb 06 and it's still a 4Speed Auto. If there are later technology out then i'm not so sure.

Also to add on what oil cooler do you guys recommend
some say
HKS
Some say
Max Velocity
Some say
Anybrand also can do the job
So what is wat

anyone has any idea why JDM has only 1 oil cooler and the MM 2?
considering the temperatures we experience in Sg and M'sia, would it better to add the 2nd oil cooler for JDM models?

The euro spec version which MM imports is detuned to meet euro emissions controls; so temps may get higher than usual.
Instead of adding one oil cooler; perhaps its a better idea to replace the existing one with one good cooler. (Which i am thinking of doing it too). Less weight, less oil flow resistance, less oil to top up, less problems.

Sorry, I dun quite understand why detuning can make the temps higher? I think that maybe the Euro spec versions just have higher specs in terms of standard equipment. PIs normally import the lower spec versions and incur less import taxes so that they can offer a lower price then install some stuff locally. E.g. Air-con, leather seats, etc.
Replacing the single oil cooler with a better one is a good idea, but I think most ATs owners will probably prefer to add an ATF cooler 1st before replacing the standard oil cooler with a better one. The auto trans could definitely do with more cooling.

The reason y the JDM model has only 1 oil cooler is becos in Japan weather conditions, it is sufficient to have only one cooler. Most of the times, it is cool over there. Whereas for export model, MM put in 2 coolers due to extreme weathers and of cos, made it into a full specs model (except for the horsepower).

Huh?? Dun hab lah... I bz flying ard, come back oni jiu go Sepang and you are busy hosting the RE guys during that time mah. Anyway my 30K service coming up soon, so might need to do some work on the car liao. Probably around end of this month or early next month.

Why i think the euro spec is hotter. Euro emissions control is one of the most strict in the world. To meet such emssions controls, engineers will have to look at the simplest way to cut emissions without increasing production costs. Tuning the ECU seems like a easier way rather than re-engineering the whole exhuast system. So this means detuning, leaning, retarding at certain points to meet emissions guidlines. Usually this increases tempretures, why? less fuel to cool the engine.
Reducing 1 oil cooler does not affect import duties much. Shipping the car with cast iron wheels will reduce costs more than the oil cooler. And jap spec models does not mean lower spec or lower in options. The headlight washer is only there because european regulations require it.
In simple logic. Temps got higher when they detuned the engine from 247hp to 238hp so they had to add a 2nd cooler.

Then if you can get KS to come down, they can tune on their full KS set for my ride. That would be sweet!

True that too rich a mix can produce less power, but it also floods the cat. Why would mazda want to do that? Flooded cat means poorer emissions and longevity and higher fuel consumption.
The strange thing is that why PIs offer higher OMVs compared to MM ones despite being cheaper and with less options. Perhaps MM has a higher profit margin and higher costs due to be restricted to importing euro spec with euro options. If they could import the 247 hp JDM version, they would. Who wants to settle for less hp?
To really test why there is a need for a 2nd cooler. We need someone to volunteer to take out one cooler and see if stock temps are indeed higher than JDM ones.
What i have posted here is also reflected by some JDM owners in the states and Aus. Hope no one gets offended. This is supposed to be just a friendly discussion.

u wan to test, i got 2 car always testing. Zavhan and my car. Our oil temp readings are always different, his higher. cos he only got one oil cooler, being the JDM model. Mine is MM model, lower hp, 2 oil coolers.
we are always comparing, always gg for test runs. So we have the results.

I oso wan 'full' KS setup...except cat and bodykit. Lol...wat ppl wan, I oso wan. Jialat. :P
Can anyone tell me what is a normal water temp and oil temp for a stock RX8 on track? I am getting confused by my multi display. Oil 117 degrees? Water 109 degrees?
