Hi there. Today’s synthetic oils are much different than in years past, so accidental mixing like you’ve described is not as damaging to the engine as in years past. However, I would recommend having the oil changed sooner rather than later so that the oil is consistent and your internal engine components are properly lubricated. Since you’ve added a quart and a half, that raises a red flag to me that you may have some type of oiling issues that should be checked out soon. With winter coming soon, it’s probably a good idea to change your oil anyways to the recommended blend and weight.
