My Stilo has a "Service Due" indicator that can only be reset by someone with the correct licensed version of the Fiat ECUScan software. I only have the free version, and so I can see the option but it's greyed out.
I guess your oil light is something similar.

Fiat multi ECU scan or multi ECU scan did not reset change engine oil light for me. I used an alltel md808 cost me 240 quid still cheaper than the mechanic who did the service and reset the service indicator but the oil reset indicator is separate and has to be reset separately.
Some people say there's no sensor which can pick up dirty oil or low oil pressure. Personally I think low oil pressure is a factor with an active sensor for it but there's a multitude of factors that caused the change engine oil warning to come on as opposed to the service indicator LED.
In my case I gave the car to the garage to check a small oil leak near the salamander belt (I don't care that you call it serpentine) but mechanic decided the engine had a timing chain and the oil leak was tiny so you didn't fix it but what I suspect he did do was chuck my clean recently serviced oil into a big fat barrel and then refilled my car with the thickest dirtiest broken down all from said barrel which triggered the oil pressure low sensor alarm once triggered I've got change engine oil LED but needs resetting as I say multi ECU scan didn't work but the autel md808 pro cleared it straight away. I did not have to set any DPF parameters no DPF reset the ECU responded with plausible DPF factors which I left alone. Some idiot care has to be taken in that the hotel can certainly change engine management parameters which in my opinion should never be changed because I trust the manufacturer more than any other authority
