Firstly yours a turbo I am presuming from your handle. So different oil requirements.
Secondly, in cold climate its best to stay with 0W 0r 5W for better cold temp engine operation.
Thirdly, will you give me a new 13b engine if it sputters and dies using 10w30?
Thought so...

Why I shouldn't use that oil? Haven't yet...I just bought it not too long ago...

Dont forget that during winter or during summer the operating engine temps are the same, so is the EGT. The only different exists from a cold start. You should choose the oil that works best for when the car is at operating temps. If this requires that you let the car warm up during winter then it is a necessary evil but you should never choose an oil solely because of a condition that exists only during startup.

You should choose the oil that flows optimally on both occasions. I hate the thought of my rotors having to turn the thick sludge in cold temp.

The point I am trying to make is 5w20 is too thin for our engines and Mazda would have asked us to use thicker oil if it was not for those retarted fuel economy regulations.

If you think its smart to use oil that is as thin as water.. enjoy!

I don't believe it's very good for the renny, to run synthetic with out a OMP adapter.

The car automatically draws motor oil and injects it in the combustion chambers.
To lube the seals I believe, when it burns.

Synthetic doesn't "burn" like "dino" oil does.

I will agree that a synthetic oil has better lube properties then "dino" oil but then it wouldn't be good unless you went with a after market OMP adapter.

Basically, it draws premix from another source(usually the windshield fluid bottle is used), and disabling the factory OMP from drawing oil from the synthetic oil that you are using in the oil pan

and that this point I will let Turborx8 explain into detail of what the benfits are because he installed one.

you can see what he did=)

Edit: making it easier for you Leesha

The point of this adapter, is to stop using engine oil to lubricate the apex seals in your rotary engine. This is a good thing because:

1. Your engine will no longer burn oil from the engine
2. Your seals can be given fresh oil that isn’t dirty
3. You can feed your seals 2 stroke oil, which is meant to be burned.
4. If you’re a firm believer that you can’t use synthetic oil because it’s bad for the seals, using synthetic oil will no longer an issue because your motor oil isn’t being used for seal lubrication!

This is where I ordered mine from.

Now I need to figure out what type of resevoir I can use to hold the 2stroke oil. Some people use the windshield washer fluid resevoir but I plan to drive my car thru the winter so that won’t work.

Why will your engine sputter and die just because of using a 10w30 weight oil?

I 'll agree that using a 0W or 5W will be better for cold starts.

That's about it.

I still think that a xW20 is still to thin in operating temps of a renny.

TURBO or NOT..

For the same reason should Mazda decides to put the blame of not following with the manuals recommendation. Magnusson-Moss is unrecognized here. For out of warranty cars, such as your turbo8 you can use Canola oil for all I nor Mazda care.

Rems31

What brand canola oil should I use??

Leesha

Thanks for the info...How much would it cost to do the entire thing??

The part is $108, and install shouldn't be too bad I'd say 50-100 depending on where you go.

or you can just someone to help you DIY with it=)

Leesha

I think this might void my warranty so I'll wait until its up. Is a good idea though. Maybe I'll get you to help me.

Yep, It will def. void your warrenty!

I switched to 5W-30 (dino) for a two reasons
1. only in North America does Mazda recommend 5W-20, the rest of the world gets 5W-30 +
2. There is good evidence that the only reason 5W-20 is recommended is silly federal fuel efficiency regulations.

What I deducted from these two points is that the use of 5W-20 oil results in unnecessary risk for MY car. I see no benefits, and I see no reason why 5W-30 would damage an engine.

Thought I'd post this...interesting...

He has "fact"..true...

But were not talking about which oil is simply use-able.

We want to put what is best.

Has Mazda USA always recommended 5W-20 or is this a more recent change? If always, and based on the information I'm reading in this thread warning against 5W-20, I'm wondering if there might be a link to the engine problems that 04-06 models were recalled for.

Nope, This did not change, I m pretty sure it was always 5w20, and still is shipped, and if you get a oil change at the dealer, they still dump 5w20 in there.

When it gets warmer, I plan to use: Royal Purple synthetic 10w30.

It seems to me that 5W 20 is the plentiful oil grade of choice of Ford, who owns a large share of Mazda. I think it's too thin, and I also think 5W 20 will lower the life span of my engine.

Ask Australians, Europeans and Japanese what they use. I'd make a bet they'll use the oil grade that is recommended by Mazda Japan.

North American auto industry, may just want our engines to appear to die young. Perhaps, some my speculate... to ensure it doesn't outlast the American piston heads? - again I speculate.

That is of course, my humble opinion. If I am wrong with my speculations, that's fine. However, I will at least ask the other geo-sites (again) on RX8Club what oil they use.

I don't trust American corporate auto manufacturers. So I am biased.
