Did a quick search for the phrase and found TWO references from the same company.

non-synthetic

synthetic

and then here is one for 5W-20 (non-synthetic)

I now know more about oil than I care to.:p I omitted the links for the EPA letters to manufacuturers about energy conserving oil.:o

RX-Nut

I hope they're the same.. Tire Rack said they were.. hmm.. Can anyone confirm?

DreamWarrior

not that I'm one to argue grammar, but jesus both:

"The fuel supply will be cut at an rpm lower than the red zone" and "The fuel supply will be cut at a lower rpm than the red zone" have, IMO, the same meaning. You throwing the words "off" and "indicated" into the second sentence adds nothing but a little more reading clarity. However, the meaning doesn't change, IMO.

The first one says that the rpm that it cuts at is lower than the red zone [line]. So if Red line ---> | here then rpm cut off is lower than red line.

The second one says that the same thing, but says it like this. RPM --> | here, and implies that the red zone is above that.

I read them all the same, and we all knew what they were getting at...so can we stop this?!?

"Energy conserving oil" can be synthetic or regular dino oil.

Tire Rack is very careful to list only verifiable information on their advertising, and have done so for MANY years. They even list the tire as "Original Equipment" for the 2004 RX-8 (see http://www.tirerack.com/tires/tires....omCompare1=yes).

I'm pretty sure they would have checked this out..........

Well, most Texans would probably say that's the case, but as a displaced Canadian, I suspect we're speaking the same language

RX8 Seller

great news on the tires :0) I will let my customers know they are avaialble from the tire rack. I will also let the reps know this as well. They knew that they would be available at some time, they just did not think that it was at this time. On the synthetic oil issue, according to the rep that was here today, synthetic oil burns at a much higher degree in temp. and the rx8 needs to burn oil to operate at optimal performance. The best way that it was explained was that you can run synthetic, but it will cause buildup at the plugs and will eventually not allow the car to fire at all. Please note, this is not me throwing in my 2 cents worth, this comes directly from a Mazda Training Rep.

Actually, some of our friends in Japan have already replaced their original wheels with aftermarket wheels. Do you perhaps mean "tires"? If so, Tire Rack has many tires listed for this vehicle.

RX8 Seller

one other note on the tires, that looks like the correct tire, but please note the availability, Not Available?? But it looks like more vehicles use this tire, interesting, to let you know the advantage to this tire, it has a raised edge that goes out over the edge of the wheel itself. It is designed to protect the wheel. Also, I blew up the picture and it doesn't look like the same tire, but I have not examined it too closely? Anyway, food for thought

Just FYI - My Bridgestone S-03 tires I bought from Tire Rack (not for the RX) have this same feature.

It's one of those, geez why didn't anyone thing of it before!

Quick_lude

Why do I feel like RX8Seller is a salesman with a lot less info about the car than me.. which is typical of a salesman.. :D
I say that with the upmost respect for the salespersons community..

missinmahseven

Um... not to nitpick, but that is the worst thing you can do to any engine, piston, wankel or turbine. You gotta gotta gotta go easy till the OIL (NOT COOLANT!) is up to temps. Your bearings, journals, etc will thank you.

And so will your wankel

The old Alfa-Romeo owner's books were quite adamant about this, since they were twincam driven by roller chains, wet-sump. Lotsa stuff to break!

True, but our overseas brethren do not have the tire pressure transmitters in their wheels. We have yet to discover whether the particular senders that Mazda is using are in fact incompatible with regular afternarket wheels, or whether they're just blowing smoke.

I want to post something regarding 3000 mile oil changes...

Back in the early days of automobile history. 3000 mile changes were appropriate.

But times have changed and so has car technology. Cars really can go a lot further today between oil changes. Fuel injection is probably the biggest factor at keeping your oil cleaner. No messy carburetors now.

When that oil change place puts that sticker up in your window, they always put 3000 miles or 3 months between changes. Even if your car doesn't require it. That's fine if you want to. But all your doing is really feeding the marketing machine.

Do you really think oil goes bad after sitting 3 months in your cars engine? (It only been sitting in the ground for how long?)
It's to make sure people who don't drive as much come in at least 4 times a year.

Let's see 4 x $35 = 140 a year from each customer they have. More if you drive more miles. They are certainly in the business to make money. The more often you come in, the more chances they have to Up Sell you that air filter change, or the transmission oil change, or that radiator flush.

Always follow your manufacture recommend guideline and you should have a happy car. Follow the more extreme conditions guideline if you wish. But don't give in to the oil changing marketing machine.
That doesn't mean you shouldn't check you oil levels and top them off every other fill-up.

3000 mile oil changes are from the past, and why would the oil change places want to change it? That's less $$$ for them.

There is nothing special about "Rim Protectors" on tyres. As someone else has already pointed out, the Bridgestone S-03 tyre has this feature, as do a number of other tyres, such as Toyo Proxies T1-S, or the Goodyear F1.

It is simply a feature that tyre manufacturers have started including to give some protection to wheels from kerb damage.

Note the Bridgestone RE 040's from Tire Rack are listed as 225/45-WR18 not 225/45-ZR18 as Mazda sez? I'm still thinking the stock tires may be a special OEM spec.

RX8 Seller

I am not doubting that most if not all of the people in this forum know more than me. It is not because I am a salesperson however but more because I am not an owner. All I am trying to do is pass along the information that is being told to us directly from Mazda Reps, just trying to be helpful. The whole tire issue is what a Mazda Rep told us specifically. I am not qualified to state this as fact or not, just repeating what we were told.

Is "energy conserving oil" just light wt oil, ie 5-20. A local repair shop told me that most of the new cars are requiring 5-20. Thicker oil>more energy to push, thinner oil>easier to push?

ggreen29

I was going to post excerpts from the manual on this; it sounds like it could be a pain in the rear. It's described as if the valve stem and the sending unit are either one piece or integrated components, with specific IDs. If you change the sending unit you have to allow some time for the receiving unit to adjust to the new sender. There are also a number things that can interfere with the receiver, like laptops and ac/dc converters. The receiver will not recognize the spare tire, so while driving with the spare you will get the warning light...the manual is not clear as to whether or not that includes the accompanying warning chimes, which could be intensely annoying.

If you try driving before the receiver accepts the new sender you'll have to stop the car for 10 to 15 minutes, then try to drive again!

eccles

I believe the chime only sounds for a few seconds when the light first comes on, rather than sounding constantly until the situation is remedied.

Richard,

Do you work at a MazdaSpeed dealership? If so, check out the MazdaSpeed Protegé. 215/45ZR17 Bridgestone Potenza RE040 tires. Not the same size as the RX-8 but the same model and in Z rating. I can't imagine them having the same name, but the 18s for the RX-8 being somehow different. Technically, I should be able to get some 18" wheels and put on the same tires as the RX-8 (except of course that I'd probably be scraping the wheel wells).

Steve

P.S. While I agree that salespeople often are not as up to speed on cars as the enthusiasts that study them with passion, I think it says something that Richard is out here on the forum trying to get an education. It would be a lot easier (as a lot of salespeople do) to just gloss over things he doesn't know or read the customer and throw out B.S. that sounds like it is true but just too technical for them to understand. Congrats Richard on having integrity and looking for accurate info. Hope it positively impacts your sales.

just a note to RX8 Seller. the renesis or any rotary does not "have to burn oil". it burns oil as a consequence of the need to lubricate the interior of the rotor housing. the oil is burned during the combustion part of the cycle because of where it is not because it needs to be. thanks for you info from the tech guys!

RX-8 friend

Oil - Mazda had problems with synthetics when they first came out. They have always said "don't use them". The engine does "have to burn the injected oil" because if it doesn't the oil will exit to the catylitic converter and clog it. Synthetic does burn, and at a higher temp. than regular oil. My 2 stroke mc spits it out the exhaust (creating a wonderful mess) because it doesn't burn in the combustion chamber. Most new cars suggest "energy efficient oil". They usually are referring to 5wXX. I don't use it, as it thins out too easily. I use 10W30. I suggest following Mazdas recommendation however, as this is a very high reving. engine.

Tire pressure sensors and tires- My friend (who is still waiting, Mazda Canada) and I were going through the RX-8 Technical Highlights CD and I was laughing at his having to deal with this (and was secretly envious When you change a wheel (buy a new one for example) you have to go through a "special driving sequence" to get the receiver to recognize the new sender (they didn't specify what it was). When the dealer service has to check a sensor, they must ensure no other RX-8 is within range. Most new tires have switched from steel belts to Kevlar. Not at Mazda's request, but because it is very difficult to shred steel belted tires (recycling). They are currently adding them to roadbed material. The Mich. Pilots on my RX-7 have the rim protectors, and they are three years old.

i should have been clearer. yes it has to burn that oil. i was trying to point out that what Seller wrote could have been read to mean that the oil was injected for some purpose other than lubrication. once it is there yes burning it keeps everything cleaner and running better by burning it, but it is not injected just to burn. is that clearer?

Despite all rumors to the contrary, here's what the owners manual says about Fuel, page 4-2:

"Your Mazda will perform best with Premium Unleaed Fuel, Octane Rating 91 [(R+M)/2 method] or above (96 ROM or above).

You may use a regular unleaded fuel with Octane Rating from 87 to 90 (91-95 ROM) but this will slightly reduce performance. Fuel with a rating lower than 87 octane (91 RON) could cause the emission control system to lose effectiveness. It could also cause engine knocking and serious engine damage."

They also say use nothing with more than 10% ethanol or any fuel system additives or cleaning agents not specified by Mazda.

I will use a maximum of 89 octane, and I'll probably use 87 octane on occasion. Knowing how these books are written, they are being most cautious and recommend premium to give you the optimum driving experience. Slightly degraded performance of an 8 far exceeds anything I have ever driven so I'll still be happy. With MPG shaping up to be as poor as it appears, I'll offset with 89/87 which according to their manual will still be ok.
