I am no self proclaimed car expert by any means but I do know how to read a manual and it specifically states 5w20 motor oil (not synthetic). My first question to the mechanic was the issue of the oil since I have used Mobil 1 for years in my Acura and Honda vehicles and still do in my wife's MDX. I am also not one who is going to pass judgement on the mechanic as a MORON, your own avatar states "Newbie Mechanic" not RX8 expert. You may very well be correct in your statements but your attitude in expressing your opinion is a bit unnecessary. The mechanic wasn't a big enough of a *.* not to approve of 5W30 in the summer.

I am reading everyone's posts with my eyes wide open whether its the oil issue or the use of premix but I have to balance this with the knowledge that I still have a factory warranty and do not want to give the dealership an excuse to not fix any problem because I did not follow the manufacturers recommendations, it doesn't take much for them to pass the costs on to you, the consumer. I will continue to read this thread with interest.

 

nevijeff - Don't forget to read the other stickies. What makes this subject kinda touchy is Mazda manages their teardowns, so there is no 'known' public proof that engine failures/replacements have been due to proper oil lubrication. The only obvious belief of this being the cause is they added 2 oil injectors to the 09' models. so now each rotor has 3.

So the best option is to be sure to do the oil changes as scheduled.... though i wouldn't wait for 6k miles

 

I never consider myself as an expert, I am a newbie mechanic thats a fact, but Im no newbie when it comes oil. Cuz instead of listening to *other people's friend's friends friends ...etc*, I study it on my own, thru my own eyes. Hmm, read tons specs and facts.

Why did I call him a moron ? cuz I think he deserves it. resist burning thats true, but if he have some common sense, he wouldnt even bring some total bs like "resist to burning and leave sludge inside your engine"

Again and again, its sad to see that dealership these days never hire any *real* mechanic who actually know wtf they're talking about, instead they always aim low, pay the minimum wage, so they can hire ppl who cant even get their GED.

 

Look at 16x's design, you will know where the problem came from (sort of)

or read RG's post about the *possible* problem

Well, Mazda has its own reason. I *think* they disallow dealerships to open the engine simply because even Mazda knows their dealership techs are morons. and have ZERO clue on how to fix Rotary engine.

My experience with dealerships is that, they can give you some bullshit like "The aftermarket intake is the cause of your SSV failure, cuz you're getting too much air" ....

 

Lol, yeah there's another thread of that just happening, guy is getting pwned for the aftermarket intake.

Yeah i'm on the RG post for the possible thread throwing a BF I'm definitely doing the trade-in end of 09 unless the 16x comes out before 2012...

I'll have to search for the release info on the 16x, searching the internet's is returning the same articles...

These are exactly the issues I am concerned about, giving the dealer an "out" so they can say you changed the dynamics of the vehicle/didn't follow the manufacturers recommendations and therefore the warranty is null and void. No one has yet stated on any of the posts I have read that the use of synthetic oil or the use of premix will not void the warranty. While both these suggestions may be valid it would seem that until the warranty is up just change the oil every 4-5K miles?

 

Dealership wants to void people's warranty simply because they're lazy, plus its ALWAYS easier to get money from customers(say, charge them full hour of labor when the work is actually 10 minutes) than file a claim to get the money from the auto manufacture(of which most of the time you will not be able to get the full hour of money, see TSB)

Its a law that auto manufacture can NOT void ANYONE's warranty for using aftermarket parts, they can void it ONLY if they can proof in *writing* that the part is the cause of failure, with a reasonable explanation that can hold in court of course. Please see the Moss ACT for more information.

You can change your oil everyday, but thats like pouring money into the ocean. For Non-Full-Synthetic oils, I suggest to change it the sooner the better.

This synthetic vs non-synthetic thing is like Organic food vs Non-Organic food. Millions of people had non-organic food and can live till 80. but who knows what they've gone thru in their life, maybe they got **** loads of cancer but somehow got lucky and got thru all of them. People can say that even Organic food eaters can get cancer, etc.

I like Organic food, they cost 2-3 times as much, but hey at least Im sure Im getting some of the *cleanest* stuff.

 

Actually the dealer can't void your warranty for using 10W30 or even 20W50, unless the dealer can prove that any problems that happen are because of the oil you used.

If you are really concerned, go to the local Mazda dealer (not your local mechanic- but an actual dealer with a service department) and ask them to put in writing exactly what oil that you have to use to avoid having your warranty voided.

Chances are the best that they will do is say that they recommend that you follow the manufactures guidelines.

But they can not force you to do so. If they did, it would be a violation of the Magnuson Moss Warranty Act, unless they supplied you with the oil (which they will never do). In fact I doubt they would even put it in writing on what grade you should or should not use.

Now that doesn't mean I would tell them what oil I put in the car if it was anything but the factory recommendation. I might tell them that I put in 5W20, but really put in 10W30. Short of an oil test within the first 2000 miles they wouldn't be able to tell anyway.

 

Never buy the first year!

 

^^^ +1

Never buy 1st yr model of ANY car.

 

Yea, seriously, no matter what, the first year is going to be relatively worse. Even the "amazing" Toyota screwed up their 2001 Highlander like no other (first hand experience...).

 

Can someone photoshop 5W-20 onto this?

 

 

....Can someone photoshop 5W-20 onto this?...

Why? I don't get it.......


S

 

Its kind of a joke. Every now and then someone will say; "how do I clean this" or "what do I use?" and someone will say WD-40 or brake fluid

 

DAMN ! WHERE CAN I BUY THAT !

I WANNA 10 CASES OF IT !

Why ? cuz I've never seen a 5w20 oil can Stop Squeaks and Loosen rust parts !

It comes in a Metal can too ! how rare is that !

 

Paypal me $1000 and I'll ship you 10 cases of it.

 

you mean 1000 Ruben ?

 

Live in the Uk just got a 04 rx8 ,went to the local auto shop to buy some oil all the local shops only stock 5w 30 is this okay to use !!!!!!!!!!!!

 

SEARCH!!!!!! OR read this thread in which you have posted in!!!

 

^
I live in Ca and a local shop put 10w30 into my car, is this going to hurt it?

I just flooded my engine, what do I do?

The oil light keeps on coming on!

What's a rotary?

 

Rotary is a toaster, I just made some french toast with it.

Yum ...

 

I am arrogant enough to say I know better than any Mazda dealership tech when it comes to rotaries! I do!

When a dealership asks you what type of oil you are using, I don't care what you really use, tell them EXACTLY what they want to hear! Anyone dumb enough not to will end up getting wrongfully screwed over.

With the way dealerships have gotten more and more useless lately, a warranty isn't good for a whole lot anymore.

 

No way, You're wrong RG !

Mazda dealership should be the one and only place for all the Rotary answers. You know why ? Cuz Mazda Recommended it ! Just like the 5w20 thing, parts, etc.

 

Yep, that will do nicely in your area.

I run 5w-20 here year round.
