The Mazda RX-8's reliability has taken a beating as of late, what with the leaked video and various reports of squeeky brakes, flooding and even failing engines in hot climates. The RX-8, however, shouldn't be written off just yet. You should know that the four-door sports car has competed in and completed two 24-hour endurance races and has been entered in its third, the Silverstone Britcar 24 Hour Endurance Race, which takes place on September 9th and 10th.

Mazda will be entering three cars in the Silverstone race that have been modified only to meet racing safety requirements and are otherwise stock, including their 1.3-liter RENESIS rotary engine.

Mazda began endurance racing the RX-8 back in 2004 when it set 40 records with two cars that drove more than 3,100 miles in 24 hours at average speeds of 132 and 134 mph.

      ALL ROTARIES DO NOT FLOOD. The carbureted rotaries never flood. The fuel-injected rotaries flood if you don't read the manual and can't follow instructions(like the aptly-named Poopy Head).

      I strongly feel that like the Z06, nobody should be allowed to own a rotary without knowing some basic skills: 1. Can you read? 2. Do you know how to shift? 3. Never run a rotary *below* 2000 RPM. 4. You must redline a rotary once a day *minimum*. 5. The rotary "driving around" RPM range is 2000-5000 RPM. 6. The rotary "fun" range is 4000-9000 RPM. 7. Do you know what a "rotary" is?

      Fail that last question, and we'll send you to the Honda dealer for a bland automatic toaster-on-wheels.

      We have two 2004 RX-8s. Both had the motors replaced at 50000 miles by the dealers, at no charge. We have had very little problems otherwise. By the by, they are incredible fun to drive and stable at very high speeds.

      You are supposed to CHECK the oil after every other fillup, not add oil after every other fillup. In my first 5000 miles I had to add two quarts, but probably could have gotten away with one. Instead of every other fillup, I just check it every 500 miles. I might switch to every 1000 once I'm sure I've got the "burn rate" figured out.

      I have owned my rx-8 for 4 months now, bought it used and new about all the issues plus the "bad" gas mileage. First lets get it straight it's a SPORTS car and isn't meant to have good mileage get over it. The car is still worth the money and then some. I haven't had any flooding issues but have had the squeky breaks. As for oil consumption it's about a quart of oil every 1-2 tanks of gas depending how much you get on it with the accelerator. Just don't be lazy and check it once a week, doesn't take that long to do. The only problem I have right now is noise in second gear (manual tran)almost like knives being rubbed together, metal to metal. Hopefully it's nothing but other than that the RX-8 rocks, my kids love it and it's fast enough for me! It gets looks everywhere I go and it's REALLY fun to drive!

      Didn't the RX-7 win more races than any other car
      in the SCCA.
      The rotary is the only Japanese car/engine to have ever won the 24 hours of Lemans outright. I think it had four rotors or 160 cubic inches of displacement?

      Who killed the electric car? Who killed the rotary?

      I own an 05 RX8. 12,750 miles later I love this car. Just ordered the Sport Tuned dual exhaust from Mazda Speed. Can't wait. Comfortable on long trips, a blast to cruise at 85mph up the NJ Turnpike, a hoot on the Bucks County twisties, and always get looks around town. I burn about 1 quart of oil every 1000 miles. (Buy a case and keep it in the garage). Brakes do squeek a little but not worried about it. Gas mileage totally SUCKS. Sticker said 19 and 25. I get 15 and 20. Around town only 200 miles to a tank. Eeeech.
      Never had a flooding problem. You just need to let the engine warm, so if you're pulling out of the garage to wash, keep it running a while. It is a tempermental car and not for everyone. If you're a car enthusiast...you won't regret it!
      Zoom zoom zoom.

      Yeah, because everyone knows you have flooding problems during a race. My RX-8 was the most unreliable pile of crap I've ever owned. Not to mention the fact that the horsepower is still over-rated.

      I've been in the auto industy for 23 years. I purchase a Rx-8 a year ago knowing that they had some issues. These motors fire all the time so they burn oil. The horsepower is just fine for the size of vehicle. My vehicle has been towed in twice because it would not start and it was because they flood easy. I told the service department the first time that it seem the starter was dragging. The second time they put a gear reduction starter on and I have not had any other concerns. To me people need to research before they purchase a vehicle. Rx-8 is a great vehicle.

      All rotaries have the flooding problem. I had a second generation RX-7 that would flood all the time. It is usually a cold start problem. If you start the car and don't let it run for a few minutes before turning it off, it would flood. On my RX-7 all I had to do was hold the accelerator to the floor and crank the motor and it would start.

      Who the hell wants a car you can't take short trips in during the winter for fear of flooding? Who the hell wants a car you have to jump through hoops with so it doesn't run like crap. Who the hell wants a car that probably has closer to 220 horsepower and yet still gets 19-21 mpg. I'd take a G35 over that crap every day of the week.

      Fortunately, the dealer that sold me the car bought it back at a reasonable price and sold me a used G35 at a reasonable price.

      Love our 05 RX8, but squeeky brakes with 2k on it!!

      As I hear it from rotary enthusiast friends, the flooding problem that all rotaries (not just the RX-8) experience is alike to Subaru's "glass tranny" myth. That is to say, if you learn to drive/maintain your new vehicle properly, and you acquaint yourself with the technology's's idiosynchrosies, you'll be fine.

      I don't know, it's possible that my RX-loving buddies just happen to have somehow gotten themselves the only four rotaries on Earth that don't flood.
