On the oil question, I noticed that Mobil One now has a new version out that's good for a year or 15,000 miles. This sounds like just the thing for those of us who only drive on nice days. I saw this at a Walmart. The cost is about $4 more, or about $24 for 5 qts.

I saw a commercial for that new Mobil 1. I'm going to wait and see what kind of results people have before I consider using it.
