purchasing the RX-8 saturday
let me start out by saying i'm a mustang guy, but i come in peace... with that said, i love the 8, wanted one in 04 when they came out but went with a truck instead. went to pull the trigger on one summer of 06 but messed up and drove a new mustang so long story short i have a mustang again. got my girlfriend turned onto the 8 quite a while back and she's finally finished her degree and started working. found her exactly what she wanted and set it up with the dealer and we're picking it up saturday. 05 whitewater pearl, black leather, auto. i've done a little research on your forums in the past, but had a couple last minute questions. how often should the oil be changed (serviced) and what type of oil is called for in the 8 and what's the most popular brand? i'm a mobile 1/ royal purple kind of guy but have never messed with a rotary before. thanks everyone

it's an AT and your gf (I take it on face value) doesn't have a dick, so I'd say go for 5k oil changes, the rx8 uses 5w-20, and if your gf (again, face value) drives like a girl, then you can use that, it's cheaper, but I'd recommend 10w-30 personally, also, just to be on the safe side, go for non-synthetic, if you want synthetic, royal purple is a normally used brand

I zoom therefore I am.
Taj's clever way of calling the new person's gf a tranny makes me smile.
Taj's advice is right on... non synthetic is what mazda calls for, 5k changes are normal... check the oil level every other fill up or every two weeks. The 8 uses oil and needs to be topped off.

yes she drives like a girl, hence having to find exactly what she wanted in an AT. (which sucks when i want to drive it) the same argument takes place in the mustang world i.e. 5w20 (ford says) or 5w30. i use what the manual calls for b/c they know a lot better about their engine than i do, but i always used mobile 1 synthetic until trying royal purple on my last oil change. and if i'm not mistaken, the 8 needs to use 93 octane correct?

Not Even Joking I Read That The Fact That The Auto Use Less Of The Rpm Range That They Accustomed To They Tend To Fail Sooner. However I Will Say That For All The Crap That Some Ppl Have Said About The Car, Its A Beauty. I Own An 8 2004 And I Love The Damn Thing. Wife Hates It Because I Pay Too Much Attention To Its Well Being But Congrats On The Buy. ALSO HERE IS THE LINK TO 8'S RECALLS GET YOUR 8 CHECKED FOR GOOD MEASURE. http://www.lemonauto.com/complaints/mazda/mazda_rx8.htm

i don't see how the AT would cause problems with engine. if the AT has problems it should just be with the transmission and drive train. it should use the rpm's they wanted it to b/c the AT is designed to redline at 7500 if i'm not mistaken. as far as gas, do the owner's manual call for 87, 93?
oh and my car is an 07

They Call For 91 But You Can Do Half 93 And Half 89 And It Would Be The Equivalent. But For All That Work Its Easier To Just Go 93 Lol. Yeah Sorry Dude If I Could Remember Where The Hell I Saw That Post I'd Post It Here. But As Long As You Baby That Sucker And Give It Some Tlc I Dont See Why It Would Go Sour On Ya. Enjoy It!

TSB = Technical Service Bulletin
They are bulletins that the dealers use to help diagnose and fix common problems. Stuff like a foamy dipstick, fog in taillights, loss of power and so on.
Here is the list:

here's the thing with ATs, they use to fail more earlier due to the oil injectors being coded for MTs and then they inject too much in and some don't get burned off, Carbon builds up because the engine runs colder
I swear to god that in the long run, it will require far less maintainance than the MT cars
1. no clutch and flywheel change crap
2. no clutch pedal brackets breaking on you
3. no changing tranny fluid every 3k miles
so there ya go

Oil weight should be just what you do with the Mustang. 5w20 vs 5w30 all over again. Mazda does not recommend synthetic oil...but you've probably read the synthetic oil thread here by now.
The most popular brand of non-synthetic oil among people here is Castrol GTX. Most of us believe in 3000 mile oil changes.
The owner's manual says that 91 octane is recommended for best performance, but you can use down to 87. Personally, I use premium because I'd rather let the timing follow what Mazda programmed into it rather than ride the knock sensor.
Since the car has all the service records, I assume it's also got the owner's manual. If it does not, you can download a pdf version by signing up in the owner's area at mazdausa.com. Even if you have the printed manual, the pdf is really worth having.
This is a really great car - you and your girlfriend should have a lot of fun with it. Remember to redline the engine at least once a day.

I put in 89 octane here in SE PA...been in 95 deg ambient temps and have not had any problems with detonation.
I use 5W30 Castrol GTX (non synth)...Mazda does recommend 5W20, but there are several threads where third parties who rebuild these engines recommend a heavier weight. I have yet to switch to synth, but I might at my next oil change in 2k miles. Check out the Expo1 Engine Rebuild thread for alot of good info about oil weight and engine wear.
Good luck with the new car.

i changed mine at 30k and will do so at every 30k from here forward until the car RIPs. manual states 60k is just fine after the first 30k maintenance. maybe 15-20k would be okay, but seriously, every 3k?!

Every 3k transmittion fluid change, really?
WWP is a fantastic choice. I had it narrowed down to Winning Blue and Whitewater Pearl... both great colors, but I think you made the right choice -=)

Teach your girl to drive STICK! She will love it once she gets hang of it (most girls do, he he) and you will have urself a REAL (i say real cuz of the MT) sports car to switch off to from the grunt of the Stang (u better have the V8). The 05 AT's are so slow and a rotary isnt truly experienced unless you can rev to 9K at will on any shift. TRUST US, convince her to get the MT by all means possible....just tell her they have less problems (debateable), are way more fun to drive, more power and have better warranty (just lie
)
An AT RX-8 and the MT RX-8 are two different cars man, they are not like other cars where the diff is minimal.
