I know someone with a Honda that gets driven 1500 mi per year. The oil gets changed annually but the oil filter has not been changed yet. I plan to change the filter at 6000 mi, which is gonna be a longggggg time. Someone told me to change the filter w/ the oil but I countered that filters don't go bad due to short trips. Short trips are bad for the oil but have no impact on the filter. Who's right?
change oil filter by time or mileage?

$20.00 a year for oil and oil filter change going to break the bank? Just change them both and forget about it.
Change the oil and filter at least once a year.....Simple
Tonycarguy - I see what you are saying. And it makes good general sens to me. The filter is not wearing out, just slowly accumulating 'whatever'.
That said, I'd change it every 2-3 years in those conditions.

A filter loads (mainly) due to byproducts of fuel enrichment states. The post fuel enrichment states don't add anything compared to the combustion byproducts produced during that time. Hence it essentially comes down to warm up miles out of total miles. That's why you get away with a filter every other time (on many engines) since the warm up miles are mostly void of those byproducts.
In daily drivers a 6k a year engine will (loosely) see the same number of gallons of fuel in warm up as a 15k/year driver will. The difference is the hollow space in between warm up miles. The 6k has none. The 15k engine has plenty.
There can be some other things involved, but that's basically it.

No, that is not basically it.
Blow by and heat are heavy contributors.
I did some cross country driving with virtually no cold starts and racked up a lot of miles. The oil and filter were dirty.

No matter what you hear change the oil filter when you change the oil.

Im a firm believer in under 5000 mile oil changes although most of my customers believe in long long long oci's but if they didn't i would not see them in my engine shop so i guess that's good for us
