Okay so the car is running fine but I think the Pennzoil premix is smoking too much so I'm gonna discontinue it and go with idemitsu.

Engine Oil:

I have been searching High and low for 0W oil and pretty much 0W30 Mobile and Castrol Syntec 0W30 are the only ones I have found and they are the same price. I did find however that Walmart is way cheaper on the Mobile 1 so if you buy Mobil 1 get it from Walmart for $22.00 for 5 quarts.

What are your thoughts on Castrol Syntec European Formula?

 

As far as I remember Castrol's Syntec 0w30 is a PAO based product (correct me if wrong)

So its good

most idiots out there didnt know the difference and just got the 5w-30 instead, which is a whack *** Group III hydro cracked junk. Well I mean Group III is good but, I am not paying GRP IV/V's price for GRP III's stuff.

 

I just read something that said the Mobil 1 0W30 (fuel efficiency or whatever) has poor viscosity ratings. So I'm gonna see if I can find the Castrol in a 5qt jug. What marking do i look for to determine it's PAO?

 

Just find the one that says 0w-30 and you're good to go.

but I dont think Castrol/BP has 0w30 in 5 quart jug ... I never seen them before so I could be wrong.

Ahh, I just checked for you, Autozone has another deal going. 5 quarts of Syntec and K&N Filter = 27.99 + tax. and if you get their rewards program, every 20 bux u get 1 point, 5 points you will have 20 dollars of store credit for free. Its a really good program IMO. I got a lot of free **** from it

 

Need some advise! I bought my 17 daughter a 04 RX8 for her bday. Im am so sorry I did this I wish I would of read some forms before buying but anyway to late for that! My first problem was rough idle n sometimes killing. went to mazda replaced motor mounts. Still has rough idle not shaking as bad!! 2nd time went to Mazda killing at idle replaced all colis by then it was cool outside so I didnt have much trouble. Summer is here n now killing at idle again. went to Maza again and now its my battery and oxygen sensor!! I know this car needs a new motor they just wont give in. How do you guys convince them??
One more thing what is the compression on this motor so I can get someone to check it for me? Any advice will be GREAT!

 

^It takes a special device to test the compression on a rotary engine. I have a compression tester for a piston engine and it won't work on a rotary.
As for convincing them to test it. It seems to vary from dealer to dealer if they will do it. If you pay their basic inspection charge to hook it up to their diagnostic machine, I don't see why they wouldn't.
I suggest you post in the SE Regional forum and see if you can get some help more specific to your area. Also, maybe these guys can help you out: http://evolvnola.com/

 

Also, make sure you mention power loss and stalling specifically. But unfortunately different dealers handle it differently.

 

Thanks for advise. Im going to look around see if I can get anything done. Thanks again

 

I have an 04 RX8, silver MT.

I took my car in because it was sputtering and stalling at stop lights. I live in central texas and this "heat wave" is ridiculous. When I took it in, they said I needed a new main cat and that they would check the pressure in the engine. Today I found out, right before goin to finally pick her up, that I need a new engine. Thankfully I have under 100k, about 97k on it. Mazda is paying for the engine and replacement, but I have to wait another week..... I'm just happy I get a brand new engine at almost 100k. Is there anything else I need to make sure gets done?

 

I would have them intall a new fuel pump since the fuel pump and filter is one unit and should be changed at 100k.

 

I hope I get a new motor!! Still blaming it on everything else!!

 

so if your second engine goes out, mazda will still replace it? even third?

 

Yep. I had two replaced under the warranty extension and I believe there are several of us here that are on engine 3 and even 4. I'm sure the statistics would be more but I know of a couple local guys who bailed after theirs were replaced the first time.

 

do you know why?

cuz the dealership KNOWS that you dont know **** about the car. so yeah they will try to make you pay for EVERYTHING ELSE first before they finally say "oh yeah the engine is bad too, but dont worry we got that one", but thats probably after you pay 1-2 K in parts for no reason.

So yeah, you should Ask SE forum to see if there is any member there would go with you to the dealership. That way, they cant throw anymore bullshit at you and will start treating you seriously.


BTW, Bad idle could be bad spark plugs, coils, wires, Fuel pumps, bad alternator, etc. but if your engine dies at stop light on a HOT day (high than 85f)

then I am 99.9999% sure your engine is on its way to heaven.

 

Stalling with no obvious reason is usually a bad motor. Both of mine had the stalling issue.

 

I got the oxygen sensor in replaced it and of course went take a ride still stop on me at the stop sign!! I just dont know what to do. This will be the 6th time in the shop for the same problem what else can they blame it on?? What do I do I cant trade it in. It wont run Noone seems to be able to fix it!! I sure cant sell it ! Im just sooo disappointed I just dont know what to do. PLEASE help me find some answers!!!!

 

Its at Mazda again!! I told them no power and still killing at idle . He said maybe the engie is going out!! So hopefully After the 6th time in the shop they will find the problem!!

 

Don't get discouraged. You just have a suck *** dealer.

 

you need to tell them to do a compression check it!!!!!

I believe as long as the odometer says its under 100k miles you get new engines after that your screwed


I wish it was based on 100k for the engine itself, but if that where the case they would probably replace motors forever

 

I've had 3 suck *** dealerships in the past 5 years and have yet to get my engine issues resolved! Good Luck

 

I told them this time to do a compression check since I have to pay a diagnose fee anyway!! He said he will look into it!

 

Well, my 2005 Galaxy Gray with 44216 miles on it is getting Number three. Then I discovered the new 100,000 mile warranty doesnt cover a rental car, But i will say this i called Mazda service and they didnt bat an eye at getting me a rental.
I love this car, best looking thing on the road, but they need to stop with the rebuild and just slap and new 2009 engine in there and move on.
GRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRR

 

You can't just slap in an 09, the cost to Mazda would be enormous, they might as well give you an whole new car...and that won't happen.

Not only do they need the all new EMOP set up, but all new engine bay and dash harnesses, all new PCM (ECU), plus other add ons...plus labor....Won't happen.

 

Yeah it would be nice though. This problem just destroys the cars resale.

 

well i understand that, but lets see replace and rebuild three engines in one car, ship them all over the country to just be rebuilt and put in someone else 8. $4000 per engine so $12000 on my car alone plus an upset customer, rental fees. I think Mazda should rething there strategy.
