Gotta say that's a really weird problem you've got there. I mean, doing an oil change is something so unintrusive, the car wouldn't even know it happened. When I change oil, I literally do nothing other than remove the oil plug, replace the filter and pour in new oil. I don't disconnect the battery, I do nothing that would "tell the car" that I did something. I later update the service maintenance log.
Is there anything that you do other than above, that might've caused your issues?
