That would be a REAL testament of any oil.

Although every minivan I have ever researched has transmission problems LONG before any other problems emerge it would be an interesting test. Mom's have their vehicles abused by kids and kids activities regularly.
Besides the Mom and Kids stuff, our minivan ('03 Montana) also gets used to haul firewood, building/landscaping materials, motorcycles, furniture, my son's band and all their equipment, etc. Sometimes all that stuff is in the van, sometimes it's on a trailer behind the van. 103K miles of hard use so far with Mobil 1 in the engine (changed by OLM) and MaxLife ATF in the tranny (changed every 30K).
My Aerostar sees similar use, less the motorcycles, and band equipment. It hauls paint and equipment instead making many short hops. I'm closing in on 190,000 miles and for most of its life it saw PYB. Recently I started using what ever dino oil was on sale. Still going strong. Your use and my use is harder on an engine and oil then these hand picked tests. Not picking on Mobil here either, a general comment here, that's all.
I'm really not overly impressed with these tests where an engine is run day and night like that. Let them deep freeze it, start it drive it 10 minutes shut it down deep freeze it to simulate sitting 8 hours and repeat the test doing that. Make it easy, log 250,000 miles that way. Then brag.
