Today was a pretty chilly day for August. It was about 55 degrees (Fahrenheit) and I didn't drive my car as much as usual. Tonight On my way home I noticed a lot of white smoke from my tail pipes. I'm used to that when it's really cold during the winter but today it was just chilly and my engine was warm. Do you think this has to do with the sudden temperature drop or do you think it's like a coolent leak or something? It wasn't doing this before. Only today.
