One thing we can do to check viscosity is to look at oil pressure (for a given RPM and engine temp). I think its some Chrysler V8s that actually set off the check-engine light if pressure isn't high enough. I'm not sure if I have access to oil pressure over the OBDII connector using ForScan. Lucky folks have oil pressure gauges.
That would cover minimum viscosity levels. More viscosity doesn't really hurt engines, to a point of course. Its too thin that is the hazard.
TBN worries, maybe just add 1/8 cup of Oil Extreme overbase at 15,000 miles to boost it.
