True that - I would have no issue doing an “interim service” like that if pushed for time - and I have done in the past as I have a Mityvac extractor, but I’d want to ideally drain it properly every time or at least every other.Everything is a compromise; changing 95% of the oils is much better than not changing it at all and doing so with hot engine oil should ensure most of the contaminants are suspended in the oil instead of settled on the bottom of the sump.
