I really would like to thank all the past responses to my questions. Yet I have another. I am noticing every once and a while when I start my rx8 I get some smoke coming out the exhaust. Usually the first start of the day and not always. Today it's a bit chilly here in south Florida, high 40's low 50's and there was a considerable amount of smoke coming from the exhaust. It's seems to have burnt off in the first 1/2 mile of driving. I hate to run to a mazda dealer and have them blow smoke up my a$s, no pun intended. A friend of mine told me that because of the rotary engine that every once in a while that may happen due to the nature of the engine. Nothing to be alarmed about. Yet I am really concerned. Any feedback? Thank you.
Ps.....the smoke is whiteish/blue.

White smoke? Oil level good? It is perfectly normal to have smoke, it is condensation in the exhaust system burning off.

The rotary is designed to inject oil as a lubricating function.
You should have to add about a 1/2 qt. every other tank or so.
If you are catless the smoke will be more noticeable.
I suggest you do some searches on it to see if you have a real problem.
Start with the new owner stickies if you haven't read them yet.

How thick is the smoke?

White "smoke" for the first minutes on a cool morning is perfectly normal. As it was said, it's condensation, not really smoke.

^ It depends on how thick it is. If it's just wispy or fast fading out of the tailpipes, then yes, it's condensation. However I dealt with a problem on my 8 where it was "white smoke in the morning", and it was enough to fill a 4-way intersection thick enough that you couldn't see across the road. That was decidedly NOT condensation.


So...how thick is it?

Well, I think it should be clear to everyone that it is NOT normal to cloud a complete intersection
From the description it didn't sound like the OP has anything even close to that.
Besides, I'd think if someone has that much smoke then it wouldn't go away in 1/2 mile and wouldn't be intermittent either.

Yes. Oil level is fine. I check it every week. Just got the car 4 months ago with 62,500 miles on it so I get somewhat paranoid when something like this happens. The guy who I bought it from changed the oil about two weeks before I bought it. Then I changed the oil after I had it for three weeks just to start off right. That was three months ago to the day which I put 1900 miles on it in that time. Funny thing is I checked the oil level every week and I thought I would need to add some during that time but I didnt. Anyway it's been three months and I am bringing it in for a change today. 5w 30 regular oil.

No. Not nearly that bad at all. Just out of curiosity what was your resolve with that?
