Thanks for the response. What you say does make sense. I haven't had my car do it to this extent before, but we've also had a long string of very warm, very humid days with very poor air quality. My biggest concern is that I could be damaging the engine. I realize that the engine oil is more fluid when it's hot of course, but still. It's supposed to cool down some over the weekend, so I will definitely keep an eye out to see if it behaves different on start-up. Thanks!
