Here's an interesting thought:
the whole "oil never wears out" - (even though it does)- Lets just say your oil lasts 7500 miles.
Oil filters- some on this site has even said it lasts over 15000-20000 miles, its just that you dont know if your in by pass due to it clogging.
Others have said to change oil, but filter only every other time.
So this all doesnt add up.
Why cant you just change filters, and not oil? Theoretically, the filter and top off should add enough back into the oil- other than the fact that whatever the filter couldnt capture is still lurking around in the oil...
