I didn't realize oil analysis was a way off suggestion . The OP obviously is questioning if he should throw away possibly good oil . The only way to know that I am aware of is oil analysis .
We have been programmed via excellent oil company marketing that oil should be changed every 3K . Oil analysis many times say's the oil and additive package can go a lot longer . It is just a data point to help make a decision .
Or as others have suggested just change it and be done . Freedom of choice does exist 😊
