I had originally asked this on a GM board that focuses on the Buick Century, and got a bit of a non answer, so I wanted to ask here just in case.
I was wondering if anyone knew of, or knew where to start to find, an ECU update that will allow my OLM to give me more accurate service intervals using the most recent Dexos oils?
I drive fewer than 10k miles a year, so I could just do annual changes with my Mobil 1 0w-30 AFE but I actually like the 'oil change" alert so I don't have to try and keep notes on that.
Thank you as always!
