Replying to: trispec2007 (Mar 25, 2008 1:00 pm) so, who do i believe? where does a guy go to get the absolute best info regarding the Mazda RX-8? on the one hand, i'd hate to buy one and start having problems with it. there's nothing worse than having car trouble. but on the other hand, if all you need to do is not shut the engine off when its cold, and add a quart of oil every 1,000 miles or so, thats no big deal. help.............  Mike |

Replying to: boswell1 (Mar 27, 2008 4:46 am) Well, it's not complete BS. Those people telling you other wise don't know the rotary engine very well. The engine has the spark plugs mounted on the side of the engine. The rotors spin around the peanut shaped rotor housing. Depending on where the rotors stop when the engine is turned off, there is a possibility that one of the rotors sets by the spark plugs. What happens is unburned fuel can sit on the rotor, and soak the spark plugs. Now your engine is flooded. Warming up your rotary engine before shutting it off makes that excess fuel evaporate. Excess fuel left in an engine is normal, but, since normal Otto cycle engines have the spark plugs on top of the combustion chamber, flooding cannot occur. Since late 2005, Mazda has equipped the RX-8 with hotter sparking spark plugs that help reduce the chance of flooding, even when someone turns off the engine when it is not warm. The rotary design is very reliable since there are only 3 moving parts. With proper lubrication, hence more oil consumption, it is not uncommon for these rotarys to eclipse the 200K mark. Why you usually don't see them do it is because since the late 80's, Mazda only uses them in performance vehicles. With performance marketing, comes tuner support. Tuner support translates into high horse power, and really testing the limits of the engine. Look at any performance engine, and what tuners do to it. Get as much power as you can before it blows. Subaru has been the latest company to have numerous engines blown because of the massive support for the WRX/STi's. I guess 300hp out of the box is not enough. trispec knows what he is talking about, and so do I. It seems as if your other sources do not. |

| To address sexica22 's mention of maple smell. I have a 2007 6sp auto 8 and I've smelled a distinctive sweet smell after warmed and idling. All engine's with antifreeze can have that sickingly sweet smell with even a small seep. My water is still full and my scanguage shows cruising water temps from 179-186 F so the smell is not necessarily a problem, just a clue to watch for FL22 coolant leak. | |

FYI..consumer reports recomends the RX8 in its 06 edition, and it has a highest rating for the following categorys Engine cooling tranny drive system fuel ignition electrical AC suspension brakes exhaust body integrity power equipment body hardware it had an average rating for paint,trim and rust, overall used car verdict above average, new car verdict average. The 04 (what i own) had trouble spots with fuel ignition below average with AC and average Electrical engine body hardware Bottom line is that if you take care of the vehicle you are more than likely not to have any more problems than you would on any other car. the sheer enjoyment of the car more than makes up for the extra TLC needed to keep the car going strong |

I gave up and had the car towed to the dealership. They said in order for them to get it started they had to: Put a battery charger on Push accelerator down for 10 seconds (to engage engine), let off Then turn key over until engine turns over, however long it takes (hince the battery charger) don't stop until it works and don't repeat (you'll flood the engine more) They say it's hard on the starter and battery, but it's what must be done. Installing trailer spark plugs and hot? battery helps it from flooding in the future. Now I hope this works if I have to do it at home! |
