I went to go from Maryland to New Jersey this morning, so when I got to the gas station I added a bottle of Amsoil PI and then filled the gas tank up on my Marauder, drove 240 miles straight to New Jersey and parked the car. I went out tonite to move it into my Uncle's garage and on startup it let out a puff of blueish white smoke, my Dad said it looked a little more blue than white, it only did this for a second, I only saw the cloud of smoke as I turned the car around, could this be Amsoil PI cleaning junk out, kind of like when you use GM Top Engine Cleaner. I am also running a Maintenance Dose of Auto-Rx. It was also very hot going up the New Jersey Turnpike, something like temps in the upper 90's and I had the car up to 80 m.p.h. a few times. The car has 25,000 miles on it, any ideas or should I be concerned, I checked the oil and it was fine.
