Oil leaks? Issues with synthetics? I don't see how. It probably goes back to why Yamamoto-san told me that he doesn't like all synthetics, specifically Mobil 1 (the most widely used synthetic in the world), while some such as Royal Purple, Valvoline, and Idemitsu are fine. I personally see this as just an excuse to get around the issue at hand and will continue to use synthetics in my car. Remember I use them in a 13B which Mazda specifically says not to use synthetics in due to potential issues with rubber seals. After several years, I am prooud to say that on Royap Purple, I have had no issues.

I wonder what Mazda will think of next? Before anyone freaks out over yet more news from the company that changes their minds more than our politicians, if you are uncomfortable using synthetics, then don't. It's that simple. If you are worried about your engine, get it checked. You may get a new fresh one out of it for whatever reason! I wouldn't argue with that.

I want to know what they did to fix the issue in the engines manufactured recently. Is the issue solved or will this be a continuing problem? I don't want to wait for an 07!

more fuel for the fire come Sevenstock time!!

ya but after you have a couple engines replaced, it get really old.

rotten42

this is my concern. I'm getting my third engine installed this week. How do I know that this is going to solve the problem. It's one think for this to happen under warranty but once the warranty runs out it's a different issue.

Not trying to take this thread off topic but what's the 411 on the Mobil 1 RG? I just bought a GTO last week and GM suggests using Mobil 1 exclusively in it.
Should I go with RP or another brand instead?

alfy28

yah i agree wit you RG, but if syn gives me more of a chance for a new engine. im going for it :P jking. but cool thread and finds guys.

rotarygod

I've never replaced an engine due to an issue with the oil I use. I never will because there are no issues with the oil I use.

rotarygod

He didn't get into specifics because he speaks very broken english. All I know is that he doesn't like it in rotaries.

j9fd3s

there is another reflash. this one opens the metering pump more

j9fd3s

so what is the issue at hand?

i dont know if theres any hardware changes on the newer (fixed) cars, but everyone else gets a reflash with more metering pump. this would suggest theres not enough lubrication for the seals?

thats also the reason they have given not to use synthetic in the rx8, it hasnt been a blanket no with no reason this time.

also the cars they expect to fail the testing (4 hours worth!) are the ones that arent driven hard.

so i dont think synthetic has much to do with it, but then again i know the what, but not the why

RevTo9K

RG, this doesn't make sense to me either. If the problem really was due to synthetic oil, you'd think they would just point to the owner's manual and wiggle out of it. Why recall all of the 04s, 05s, and some 06s for a problem they believe is caused by synth?

Time will tell... if we get lots of 'Never used synth... getting a new engine', I guess we'll know.

My motor has been quite flakey lately. Maybe when the bullitin is out, I'll take it in and get a new motor. And they better not send me to enterprise again.

rotten42

I'm not saying it's because of the oil. I just hope they get a real handle on what the hell is going on. It's not just happening in hot climates.

RevTo9K

Is that four hours of labor, or four hours of continuous running? Also, where did you hear this? (just curious)

rotten42

I had the flash done

map

So this sounds like what is happening to me. First they will recall all RX8s for compression testing. Those that fail get a new engine, those that pass get a new flash to increase oil injection. Is it safe to say that if a compression test comes up fine that there has been no damage to the engine? Or is it just that possible damage hasn't shown up yet? Hopefully since this issue is now being publically recognized by Mazda they will support engine replacements past the traditional warranty period.

One thing i don't get though. If it's a lubrication issue wouldn't that effect people who rev the engine high more since more movement requires more lube? It sounds like there is more at work here.

Clavius

If this is true I can't wait to see the line of Rx-8's infront of my dealer's service dept.

devious12

Is there anyway to perform a vacuum test myself so I can be assured that the dealer isn't bullshitting around?

mysql101

Does anyone know how this will effect those of us with turbos installed on the car? Will they check and replace our engines too?

zoom44

i hint these things as strongly as i can

but i am glad to see Mark Rechtin at Automotive News was able to pry it out of them , there are any documents to post about it yet. As soon as they become available ill add them to this thread. I even checked the NHTSA site last night about midnight but there wasnt anything yet.

You can see now why those TSBs have come out in Europe and Australia. There are certain types of Synthetics (sorry Fred its true) that they have seen contributing to the Issue with failing engines in the hotter areas (Vegas Lubbock Phoenix etc) and why i posted that bit the other day with Mazda having oil samples from each dealership. It is less costly for Mazda to say "no synthetics" than to pay for testing of all the various synthetics to say which ones are ok or not. Is Royal Purple ok? yeah no doubt as i know those guys have actually tested their oil in rotaries. Up to you to decide if you wish to risk your warranty.

Im a little concerned (not just me but several Top Rotary people i have had the chance to talk to recently) about the Reman engines, especially in light of the recent multi -engine replacements where the Remans failed right away or very soon after replacement.

The remans use d to be doen by a company in florida- but they are now done by this Delco outfit in North Carolina. There already appears to be a quality conrol issue from there and with many more engiens to do the QC problem could compounded. Of course the top tefch people at MNAO are aware of this as well since they are spending many days and nights in Vegas. Im sure they have a plan to deal with this but that doesnt make me any less nervous about NC Delco remans

Itd be nice if they could do the type of longevity and cooling improvement work i heard about this weekend which will be available from a certain well known rotary house in Georgia. I doubt the Delco people could tho.

alfy28

i agree 100%, but i just want a new engine :P. but yah i agree wit you. been having my 8 since 04 and never had issues with it. had done all the nesscary recalls on it .

Ike

I agree with RG, the synthetic oil comment is just smoke and mirrors. It's easier to place blame on weather and some oil than it is to admit that there might be an issue with the design. It's like the horsepower fiasco, they're trying to divert as much of the blame away from themselves as they can.

rodrigo67

I was being sarcastic...

There are alot more cars getting thier engines replaced then you think and many are on thier 3rd engine, with one poor guy on his fourth. All this is 2 years. Does not promote confidence in the car, no matter how much I love it, but I will say Mazda is doing better then I expected. It will be interesting to see what happens to an 8 that needs an engine and is over warranty...
