Burning some oil? (smoke at startup)

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.
