Mix of highway and city. I would say most likely I have it in auto mode, but I put it manual mode here and there. Most likely I do this when getting onto the highway. I am located in Wisconsin, and do not take alot of long trips in heat. The longest in summer would be about 1-1.5 hours on the highway. When I do enter the highway in manual mode, I will get to the 7,000RPM level in 1st and close to it in second. I have done that in the city as well with manaul mode where I will run it higher RPM's

'04 model year with an auto tranny in hot climates is where compression problems are most prevalent w/8s.
Auto transmission models have only one oil cooler which is not enough. Rotary produces lots of heat. It's inherent to the design.
Manual models have dual oil coolers, and this helps keep things tame under the hood in hot climate, stop and go driving.
At any rate, the 100,000 mile/8 Year Warranty offered by Mazda on all 2004-2008 RX-8s, whether bought new or used, and even reimbursing owners for core/housing problems when they were formerly out of warranty is a class act.
One other thing, the new Renesis has a third fuel metering pump, whereas the last gen only had two.
I love Mazda for keeping the rotary alive and well. It is unique, and while it has some negative aspects such as low torque and poor fuel economy (although I just broke 22 mpg on mixed driving for the first time, which isn't terrible for sports car), it has redeeming qualities in spades - especially that 9,500 redline that just makes beautiful music, while helping to keep the weight way, way down.
My 8's handling is nothing short of amazing. And the braking is phenomenal too.
I love this car more each year.

Got a call from the dealer today. After compression tests and other tests sent to Mazda, Mazda will replace the engine. At least they stand behind their product. Will keep you posted on what it is like when I get it back...
Question - how does the warranty now work on the new engine? Does the warranty start over for the engine only? Or does it continue from where I am now?

I'm thinking of purchasing a used '04 rx8!! I test drove it and fell in love with the car. It's at a dealer, but I spoke with the previous owner and the engine has already been replaced in this car.. So I guess what I was wondering is did you find out how the warranty works on the new engine? I'm a college student and a part time worker when school is in session.. Sooo I can't afford to buy this car and then have to pay to replace the engine also..
Any answers, comments, suggestions, etc... are appreciated.

The engines are fine. You just have to check the oil every time you fill the gas, since it burns oil as part of the design.(sort of similar to a 2-stroke engine in that way).
The new one coming out this fall, though, has a much better and larger oil system, plus better styling(IMO) - it looks meaner and more aggressive. And I suspect they tweaked it just enough to get that .1 second difference between it and the Cayman sorted out.

Not all engines are OK. I just had mine replaced, '04 AT. As said, make sure you check the oil levels. Read this board and review what some very knowledgable people have to say. I do not consider myslef to be that, just a normal owner.
When it was replaced, the delear said the engine will remain under warranty, either for the balance of the warranty or 1 year which ever is longer. (not sure if that is true, but from the dealer). But mazda has recently come out to extend the warranty on the rx-8 engine to 8yrs 100,000 miles. I think it does not matter if you are buying it used....but make sure to ask.

The problem, for the most part, is model year '04, especially with the automatic.
The automatic only has one oil cooler. The manual has two oil coolers.
Most of the problems with the Renesis have been overwhelmingly automatics, and a good chunk of those have been the first year of production.
The new 8 year/100,000 mile warranty Mazda has issued, which transfers to second and third buyers, should provide peace of mind.

Check wire harness connectors under airbox, if moisture or coolant drip on it you will lose P/S. yellow steering wheel will appear on Dash.
You can also disconnect Battery poles for 5 min and reset CPU.
