[200q20v] oil change question

[Bernie Benz]

Do tell!  Suprise!  Higher viscosity = higher oil pressure!  So what?  Who
cares?  This just is not the critical, nor even a significant factor.  Of
95% of the oil circulated in an engine, its only function is cooling, not
lubrication, and most any viscosity will work for this purpose.  In general,
higher oil pressure means lower oil flow, and therefore less cooling
potential, and is unrelated to lubercation.
