Who give a shit about "Oil Life" if it truly doesn't mean much, give me a "x% oil remaining" notification/reading.Oil life is how much more you have until changing the oil. It's based on some algorithm that takes into account driving style (idling, city or highway driving), engine load, temperature and who knows what else?
The low oil is simply a switch that the oil level I'm the sump is low. It's like a float switch.
The two things are not really related. I mean, unless your "change oil" message comes on AND your oil pan is also low, then you'll get that message you showed that says "add oil."
