OCI age-old question

I would not change it now. Perhaps wait another year

The Buick will die of old age and dry rot before the oil is unserviceable.

So far the advice is that the oil needs to be changed and it does not need to be changed.

Yes, it could go either way - and I’m pretty sure it will

I would change the filter and top it off with some new oil.
