I know this is not quite a tractor question . . . but you guys appear to have really done your homework on the oil issues, so I thought I would ask your opinion on the best synthetic for a 2006 Toyota Sienna mini van. It has 15,000 miles and has one year more of warranty (so I am obligated to change out at 5,000 miles). I was looking at the Mobil and Penzoil brands. Suggestions?
