I've driven my car only 146 miles since my last oil change and I just noticed that I'm due for my yearly oil change. I am aware that Scotty says to change the engine oil at least once a year because the additives in it break over time. I am not aware of any additives or other factors that break/deteriorate over time that would call for replacing my lightly used oil filter at my next oil change.
I'm thinking of unscrewing my oil filter, emptying the oil in the oil pan, screwing the "old" oil filter back in, and completing my oil change.
Quoted from an advanceautoparts article:
```
Do You Need to Change Your Filter Along with Your Engine Oil?
The quick answer to this is “yes.”
Let’s explain why. The oil filter is designed with paper and fabric medium arranged in pleats – this medium traps particles that are no bigger than a few microns in size and prevents them from circulating through the engine, where they can start to build up on rotating assemblies and cause damage. (For comparison, an average human hair is 60 microns in diameter.) When the filter is completely saturated and can’t absorb any more contaminants, it’s essentially bypassed as the oil circulates. The particulates are still trapped in the filter, but what’s in the oil can’t be filtered out…and that, of course, is when it's really time to change the oil.
```
It seems to me that my current oil filter is nowhere near being "completely saturated" and there's no reason for me to change it for the reasons that the article stated. A possible reason to not reuse the oil filter is that if I were to reuse it there's a small chance that I might dislodge the particles trapped in the filter and they would end up in the new oil.
Should I change both the oil and oil filter?
Should I change the oil and empty the oil filter of the old oil?
Should I change the oil and not touch the oil filter?
I would still do both. They are relatively cheap.
As Scotty would say, oil is cheap, engines are expensive.
Speaking just for myself, I would spend the few dollars and put on a new filter even though my brain is telling me it's not really necessary.
i make sure oil and filter are always changed at each service,for the few dollars for an oil filter its good peace of mind.
