I think the OLMs vary by manufacturers. My friends Camry simply has the light come on every 3,500 miles. My vehicles indicate an oil change is due at different milage intervals depending on the type of driving I've been doing. I'm not sure if any OLM has the ability to detect the quality of oil you've used.
Huntindog's advice is sound; use a quality oil to protect that expensive vehicle and follow the OLM. You can't go wrong!
I think you're right; my Tundra has a light that turns on every 5,000 miles so I don't really think it's a monitor like in the wife's Chevy traverse that looks at other parameters to judge the remaining percentage of oil life.
