I have a 1995 mx6 2.0 5spd( I kno, I know, but i love the gas mileage, around 37mpg). It has 234,000 miles on it (I bought it new) and its recently started doing something odd. In the morning when I crank it i get a cloud of blue smoke, always in the morning. Now normally I would jump to the rings, however it does something a bit different. It it sits for more than a day or two, no smoke, runs great. This hasnt been gradual, it just started one day. The only thing I can think of that I did to the car was I added some stp oil treatment to it and very shortly afterwards it began to smoke. May not have anything to do with that. Anyone else have or had this problem? or any ideas ?
