Blue smoke is oil burning in the combustion chamber and coming out the exhaust.
I would suggest checking the oil level each time you fill up with gas just to make sure you are not getting low. Then keep a case of oil in the trunk so that you can top it off as needed.
This is caused by the rings not keeping the oil out of the combustion chamber and will only get worse. If the engine was overfilled with oil then that will cause the same thing because the crankshaft will splash the oil up onto the cylinder walls and gets burned out that way. Once it is put back to the proper level this will stop.
Here is a guide that explains the condition in a little more detail:
Let me know if you have questions.
