I have a 2005 mazda rx8 with a little over 30K miles. I learned of the engine flooding problem early the hard way, a.k.a, you don’t run the engine for short periods of time when it’s cold. you must let it warm up or you will flood it and have to be towed in. I live in new orleans and on a balmy december day (63 degrees) I backed the car out of my carport down the driveway and turned it off to put air in the tires. I subsequently moved it back into the carport. the next day it wouldn’t start and sounded very odd when I turned it over. it got towed in to the mazda dealer. their immediate response was that I had flooded it and temperature didn’t matter. the next day the dealer told me that I had no compression, had probably blown a seal and that the engine would have to be replaced. I read on the web that seals were a problem with these early rx8 engines and that that mazda had thankfully extended the warranty. I have also heard from a small engine mechanic that ethanol in gas was killing the seals in lawnmowers and the like.
so, my question is: should I avoid gas with ethanol to save my engine?
