*Software senses if a more frequent oil change is needed, but factory prescribes the actual oil change interval.
dump some old black oil on it and watch it say it needs changed. i bet it is a light sensor deal. and probably has nothing to do with vicocity of your oil.
It tests the amount of acid in the oil. It's the same type of test we perform on refrigerants in the air-conditioning industry. We only "changed" the main engine oil in the USN fleet ships ever 7 years. We did have oil purifiers (one of my responsibilities as a Machinist Mate). And ran an oil test every 15 minutes while the ship was underway.

Doesn't work based on a light sensor or viscosity. It works by measuring the capacitance and resistance of oil being tested. Fresh oil has a lower dielectric constant than dirty oil which is more acidic (higher dielectric) and might even have some metal particles in it depending on wear of the engine.
With the gas mileage I get the cost of oil is the least of my problems.

i used to never change my oil. so i must have been doing it right then. all of the enignes i have ever lost have been low on oil or i just added some to fill it up.
