QSUD 5W30 on few cars... suggestions

Hey guys, I bought 12 x 4.7L of QSUD 5W30 for $18 a pop at the local Walmart. I use this oil on a 04 Sienna 3.3L, 09 Malibu 2.4L, and a 00 Camry 2.2L. None of these three cars have a sludge problem. No varnish, nothing. All three cars are in Southern Ontario, and mostly highway except the Sienna. The Sienna will be a 5min commuter, back and forth mostly. I am wondering what kind of OCI I am looking at for each vehicle, realistically. Your 2 cents would be greatly appreciated. All the cars will run on MANN+HUMMEL oil filters and air filters. Thank you. The QSUD is the new SN version with a manufacturing date of April 22, 2013. (black label)

QSUD SN formulation will handle 8000 miles/12,000km in my turbo Cruze that's pretty hard on oil. I'd run it 10-12k km in the highway-only vehicles, and 6-8k km in the Sienna.
