Madzda Extended Warranty

I have an '04 MT with about 35k miles on it. I haven't had any probelms with the car, at least not yet.
Is the extended warranty offered through Mazda something that I should even consider? Or is it really a waste of money?

i usually get an extended warranty with any used car that i get. honestly, i research the hec out of the 8 through various web postings and read a lot about the experiences other owners were having with their 8's. i purchased an '04 MT with 27K on it a month ago and i opted to get the extended warranty. it was only and extra $10/month added into the payment and it covers me for an additional 3yrs/36K on top of the standard 4 yr/50K that Mazda gave me on the '04 so it's really piece of mind for down the road.

Maintenance

I plan on buying (financing) an RX8. But before I do, I want to know how the maintenance is. If I needed an oil change, could I do it myself? If I took it in, will it cost over $50-60 dollars? Or is it like a mercades where everything has to be specially made for the car, oil changes are like $200?
Is it true that I have to put more oil in every other time I fill put gas in my tank?

yes, you COULD do it by yourself, but there is really no need to. i take my car to the mazda dealership every time it is time for an oil change becuase for 1. it is only 29.75 total. #2 they do an entire fluids check and even check the extras like tell you how much your tires have worn and they inspect the car for anything else wrong. with the cost of the oil and oil filter, you are already using up half of what they charge you.but considering you have their knowledge and skills of your unique car put into the maintenance, it is so worth it to pay 30 dollars.. plus you know it is getting done right..... now for the myth that you have to put oil on the car every other tank of gas, that is true.. you wont have to put much in, but you should check it every other tankfull and try to keep it at the full mark. considering you can do this in the same time it takes to full up the tank.... its not wasting any time, but it is so worth it to have that car.. i do kinda suggest that you check out this site or do some research on the rx8 before you by the car though becuase it is different that any other car.... te rx8 likes to be revved and it is actually worse to not rev it than it is to rev it, and so on..... jsut go to this site and read stuff and look around about it...http://www.rx8club.com/index.php

Well, here's another contribution to this discussion. I was at the Mazda dealer yesterday getting my first oil change and took the opportunity to discuss this issue with the Service Manager. He agreed that the 5W20 was not optimal for engine and brought out a container of Motul 8100 Eco-nergy 5W30 100% Synthetic oil. He told me that this oil and the other fluids in this line were used by Mazda to obtain their performance specs for th Rx8. Of course, short term performance measurement and long term care of the engine can be two very different things and when I brought this up he showed me a letter from Mazda Canada endorsing this product for long term use in the rotary engine.
I also raised with him the issue of seal hardening through use of the synthetic oil and he indicated that in his experience synthetic was easier on seals than conventional oil. I'm no chemist, so what do I know?
I've noted discussions in this thread relating to weather conditions and the consequent effect on lubrication. While Toronto summers these days have too many days in the mid-30's (mid-90's F) we certainly don't have the consistent heat of the southern states. Perhaps this is a factor in Mazda Canada's endorsement of the synthetic option.
Comments?

I have an 04 rx8 6 speed with 91+K miles. My engine blew two days ago. I used only the 5w20 GTX and whatever Mazda put in there. I have learned from a MFG of the RX7 engines that the APEX seals in the RENESIS are 1/2 the thickness of the RX7 specs. My advice is find out whatever you can about keeping the engine cool. I live in N.FL and most of the miles on mine were highway. I did not opt for the extended warranty, but this is a warning to ALL RX8 owners. Change the coolant and oil frequently. There is no reason my engine should have blown at 91K miles and I have a feeling as does the dealer here in Tallahassee that Mazda is going to see most of the RX8 engines go at 90K+ miles. Especially since the APEX seals are 1/2 the thickness of the orginal design. A rebuild from MAZDA will cost you $6100, and it comes with a 12 month 12k mile warranty.
I love the 8 and the Zoom Zoom, and having owned an RX7 thougth the 8 was great until two days ago!!!
Be Warned trade it in before you warranty expires or purchase the extended warranty that covers the engine.
Good Luck to all you 8 owners.
signed, a soon to be EX 8 owner.....

Fickled Car (won't start)

I bought the 2004 RX8 when it first came out and currently have about 29,000 miles. I have been experiencing the car not starting if it sits past three or four days...This have occurred for more than five (5) times now and I have to call roadside assistance to have it towed to the dealer for them to start (decompress the engine) the car. However, they keep telling me that the RX8 is a "FICKLED CAR" and everyone experiences this if they don't start the car for a period of more than three days. I just don't believe it and would like to know if anyone else is experiencing this problem before I tackle this legally with Mazda. I don't want this to be my bill when the warranty is expired. The car have plenty of power in the battery, it appears to be a fuel problem while the engine is trying to turn over...Can anyone provide suggestions or comments on this?

I have had only one occurrence of this....I started the car on a cold day and ran it for only about 30 seconds and then shut it off. 15 minutes later it did not start. Otherwise this has not happened. I have a 2004 AT with 32,000 miles. Runs great. I had heard before that the 2004 batteries were under sized and I think my delaer did replace it with a larger model (not positive on that though, would have been awhile back).
