You are in the Mazda RX-8
What is this discussion about?
Mazda RX-8, Coupe
Jul 07, 2005 (12:36 pm)
I have felt that the RX-8 has been one of the most unrepresented of the medium price range sprts cars. Ever since its humble beginnings as the premeir car of the X-Men movie this peppy machine has been under the radar. I don't think that it is so much their fault as ours in the sense being a native New Yorker nobody talks about Mazda except for an occasional "zoom zoom". I wish that in the future years people will begin to see the true performance of this machine, and get past the fact that it is a Mazda. For a great review of the RX-8 check out carlist.com

It is good news/bad news. Mazda can't sell them (or does not know how to) so you don't see them much on the road - so the 8 owner has a special/rare car. Further good news is you can get a new, left-over 04 off a dealer lot TODAY for $4,500-5,000 under INVOICE or just get a new 05 for $2,500 to $3,200 under INVOICE.
The bad news is resale value is terrible - with so many unsold on Mazda lots folks selling a used 8 have to take a beating. A bad beating if they purchased near the 04 model release when no discounts and even gouging over MSRP were the norm.
With "more accessible" competition competing in the same price area - G35 coupe, 350Z, new Mustang GT, etc the "quirky" RX-8 with its under-torque feel just not appeal to most folks. It does appeal to ME - which is all that counts

I was asked about the MPG on my AT. I've been taking notes for some time and can state the following: Per tank, I can go about 80 miles farther on the highway, than in the city.
Example: On the 4th of July, I spent the morning driving around the city (Ft. Lauderdale) getting stuff for a trip to Disney World - used a full tank - got 240 miles. That afternoon/evening I had to drive, via the turnpike, to Disney. The "Tank Empty" light had NOT come on and I had driven 320 miles. So, with a 15.9 gal tank, that comes out to 15.09 MPG City and 20.12 MPG Hwy.......both acceptable to the way I drive! Your mileage may vary.......I know on my trip around the US in April, I was getting 340+ to a tank, at times (21.38 mpg Hwy).
Maybe at some point Mazda will be able to do some sort of trick, like one less spark per rotation, to save some gas....if at all possible.....Pathstar could enlighten me!

Well, less sparks would make it even poorer. That's the premise of MSD ignitions, one of the first multi-spark ignition systems. They ensure all fuel in the combustion chamber is burned by firing the spark plugs 2-4 times in rapid succession. When you burn all the fuel, the fuel you inject into the engine gives you more "push", thus requiring less fuel to do the job.
Unfortunately, installing those ignition systems in the RX-8 would be very expensive (you would need four sets).
You are probably thinking of the system they use at Chrysler where they shut down cylinders to improve mileage. If you tried to do this in a rotary, the engine runs very roughly. Makes you think it's going to spring out of the car!
I am not aware of any other way to improve the mileage, except the ones I have mentioned before:
1. Don't let the car idle very much. 10 sec. each time you start it before moving is plenty. The RX-8 uses a lot of fuel at idle.
2. As with any vehicle, avoid "jackrabbit" starts. Drive smoothly.
3. As with any vehicle, try to plan your trips to minimize slow travel - 40 to 50 MPH is where most vehicles get their best mileage, so avoid routes that have low speed limits where possible.
4. As with any vehicle, when practical, let the transmission slow you down when coming to a stop. The manufacturers don't like us to use the transmission in this way, but when doing so, the engine shuts the injectors down to minimal fuel. You are, in effect, recovering the energy the car has while in motion, instead of wasting it in brake heat, the premise that hybrids take advantage of.

I saw a white RX8 at the car wash today. It had a MazdaSpeed Exhaust and what looked like a rotary accent ground effects kit. I've never seen a white one before...It was really a sharp looking car.
On another note, I saw a lot of RX8s in Pittsburgh when I visited there July 4th weekend.

It is AMAZING how many folks do not know how to compute something as simple as MPG.
1) Fill the tank until the pump clicks off
2) Reset the trip meter
3) Drive until you feel you need gas
4) Fill the tank until the pump clicks off
5) Note the gallons needed to fill the tank
6) Divide the miles on the trip meter by the miles needed to fill the tank - this is your MPG for that tank
7) Reset the trip meter and repeat from step 3
Note: if the pump clicks off too early before your tank is full, then you should go ahead and continue fuelling the car until it clicks off at full. Don't "top off" since you will not get many more miles with the little extra, but you can get gas on the car, on you, or maybe ruin the charcoal canister.
You drove 320 miles but divided by the size of the TANK (15.9 )- so figured you got 20.12 MPG. If there was still 2 gallons in your tank, then you really got 23.02.
Use the gallons needed to refill and not the size of the tank - and you can compute the accurate MPG no matter if you refill at 1/2 tank, 1/4 tank, or with the light on.

hey whats up, ive just joined and as i read on i see ur name and the input u haveso graciously given. i have recently purchased an 04 RX-8 with the GT package. now what im wondering is did i make a right choice on purchasing this car. ive read the problems and solutions forum and it seem like u know ur shit, needless to say i was impressed. anyway im reading that these cars have some problems right off the lot. should i worry? what should i look for? and what kind of oil do u use, royal purple?
Jul 11, 2005 (5:27 am)
I drove the 05 and I love the car. We would love the NAV, but read it needs updating. I do not expect many changes for 06, but would like to know what is coming before I pull the trigger on a purchase.
There are a number of dealers within 75 miles and a few models that I would love to have are in stock. What kind of numbers should I be looking at for final pricing in the Northeast US?
Any news on 06 changes?

Do you like the car? If so, you made the right choice. If you don't like the way it drives or looks, maybe you made a mistake.
All readers of this and other forums on the net should keep in mind you are seeing the problem cars on these forums, almost exclusively. I would guess 95% or more don't have any issues and are happy. I think the last report I saw said all makes of new vehicles have an average of two problems requiring dealer intervention.
While I do like Royal Purple products, Mazda do not recommend synthetics. I'd stick with "normal" oil, at least until the warranty has expired. You don't want to give them a good excuse to void the warranty. Stick with the weight recommended in the owners manual as well. If you follow the operating recommendations in the owners manual you should be happy (when cold, don't start it, pull forward and shut down - ie let it warm up before shutting off - that's the extent of the "special care" required).
In short, drive the car and enjoy. You have a good warranty to protect you should the improbable happen.

06 models will be introduced in October. Mazda have been pretty good at keeping their cards close to their chest. Im told by insiders you will be able to see the big surprize for 06 at "Sevenstock 8" in Irvine Ca. (Mazda USA HQ) in early October - it's a very big get-together of rotary owners with their cars. Just search for "sevenstock" on the net for more details.
Rumor has it there may be a supercharger in store for the Mazdaspeed RX-8. There are also rumored new transmissions. We'll see in October.
