I've been using 5W-30 Penzoil Platinum in my wife's van which calls for 5W-20. Was growing a little concerned running the heavier weight, but now feel good about continuing to use it for the increased engine protection.
I must say however, the oil in her van looks and smells better after 7500 miles than the oil from my Civic Si after 3-4K miles. Same oil, different cars....it's getting much more of a workout in my Si ;)
High rpm engines puts greater toll on the engine oil.
