I've noticed my 2000 S Tip would occasionally smoke out the exhaust when I started it but most of the time it's smoke free. Yesterday I finally recognized a pattern - if I start the car and only move it a few feet, then restart it again much later (like the next day) it smokes quite abundantly. I can't tell if it's all oil smoke or a mixture of oil and unburnt fuel. Even at over 100k miles the car doesn't seem to consume any oil between 5,000 mile change intervals.
This week with the severe weather here in Arkansas I started the car to back it up a little farther in the garage so I could squeeze a motorcycle in front. I didn't get around to driving the car again until today and it smoked a bunch when I started it.
Any ideas what causes this and whether I should worry about it?
