Replying to: xd2 (Apr 22, 2009 9:30 am) On gas I city drive mostly and get 17MPG on full auto non-aggressive style. When I paddle shift aggressively MPG goes to 12. In the winter, here in Massachusetts, I don't worry so much about that first line as much. One good thing, on the pure highway trips I take down south, there is very little oil usage. |

I get a consistent 282 miles to the tank, using 13.5 gallons to fill up, with a mix of 50/50 city and highway driving. And I do not baby the car. Driving the rotary hard is literally preventative maintenance. The harder you drive it, the longer it will last and the stronger it will get. Do some research and you'll see that this is demonstrably proven.

I own a 2006 Winning Blue auto RX8 and love it. Has anyone upgraded their GPS system and what is involved? Price, etc? How often is a new disk available? I have ended up in a few parking lots recently, and one back yard.  LOL. Thanks for the great forums everyone. |

| I have a 2007 RX-8 with 21,000 miles on it. I was in the dealer today for a oil change and they suggested that I replace the cabin air filter. I declined to do it today because I looked all through the owners and service manuals that came with the car and there was absolutly no mention of a cabin air filter for this car. Was the dealer just making this up. | |

Hi folks. I've not been here in awhile. Thought I'd update this little forum with some practical wisdom. My Check Engine light went two nights ago in downtown Boston. I had been tweaking my parking spot right in front of the Boston Ballet building, trying to make sure none of the Bostonians, with their "bumper banging" parking technique, banged into my RX-8. After several starts and stops, with the engine warm, where I revved to 3000 before shut down, my "Check Engine" light lit up. I instantly grabbed the manual, and it seemed that the most likely issue was a sensor problem, caused by my starts and stops. I drove home slowly and thought the issue would disappear by morning. It didn't. So I drove to the dealer. The dealer charge me $95 to plug the system up and have the computer tell me that an Error #22, which is the SSV out of spec error. It tested fine at the dealer, but it'll be $700 to replace if it occurs again. Here's hoping it was my stop and stop parking that caused it. In the mean time, they also found that both of my engine mounts had gone. They said mine had lasted ten times longer that anyone else's. Over a year ago, a cold engine vibration had started, but I had just put up with the vibration because it went away once the car was warmed up. Well, that vibration was the bad engine mounts according to them. So I had been driving around without good mounts for a long time. I must have had my car for service and oil changes half a dozen times during that time and they never checked the mounts. Ugh! Anyway, $525 to replace both mounts, $95 to diagnose a potential future problem. An entire year of driving around with a potentially dangerous engine mount flaw. Here's the wisdom. An RX-8 AT when idling, cold or hot should ALWAYS be purring, not harshly vibrating. An RX-8 MT, when engaging the clutch, cold or hot, should ALWAYS be silky smooth, right up to the stall point. Otherwise, check the engine mounts! Still lov'n my sweet ride. Did my fourth 2000 mile Boston to NC beach run. Two 10 year olds, my wife and I. Listen'ed to Harry Potter all the way done. Fantastic way to travel, by RX-8. I still feel just like Harry Potter on his Nimbus 2000 and his Firebolt, every single time I drive my RX-8 AT. I so love my car.... I don't really even care about the $600 bucks anymore, because she's driving like new again... so nice and smooth.

Replying to: mikemartin (May 18, 2009 8:21 pm) LOVE MY CAR. I have no issues at all. It's a 2004 GT 6-speed with 25,000 miles on it (yeah, 5 years old with that kind of mileage). The engine is still under warranty until 11/2010. I use cheap dino oil, as suggested in many forums. It loves to be "rode". I check the oil once a month, I let it warm up for 60 seconds when the day first starts and I make sure to red line it twice a week so everyone involved remembers what this relationship is all about. My next car will, probably, be another slightly used RX8. I've had it for 7 months and still can't believe it's mine.

Replying to: m3metro (Oct 12, 2009 3:38 pm) The check engine light came on about 1 month after purchase. Although it felt like it was going to stall it didn't, and I took it immediately to the dealership where I purchased. They were not aware of the starting procedures and managed to flood the car and were not able to get it started. In trying to get the car started again, they informed me that there was low compression and that the engine was shot. Shortly thereafter they notified me that they had gotten the car running. One month after the car home, the check engine light is on again. At this point, the car is not exhibiting the stalling issue. I took it to a different dealership, and they too informed me that there is a compression issue. My confusion is that I have read many posts saying that compression may not be the issue? Additionally, I have been told that the car needs to be revved slightly prior to turning off the car, and then told that is nonsense and does not need to be revved? Are there any experienced rx8 owners that are willing to provide some insight to a rx8 newbie? Any would be greatly appreciated. |

Replying to: seapal (Oct 21, 2009 1:24 am) I live in Boston. Even here snow tires really are not required. My cheap all seasons handle 4" of fresh snow. The traction control and LimSlipDif handle the slippage. Snow tires might handle slip better, but the car bottoms out at 5" so nothing will help with that.
