What oil to use in my new (to me!) Volvo 240 wagon.

10/30 Valvoline Maxlife and Mann Filter.

Well, for winter I'm going to run my usual Mann filter, and some 10-30 GTX I have laying around.

Here's a question: When summer comes around, how does 15-40 Rotella T sound? I can get it free from work...I'm thinking of putting it in both my Volvo and my '81 Datsun 210 for summers.
