What I am asking is, I guess there's no way to test the life of the oil filter?
Also If I use mobil1, do I need fram "extra life" oil filter? I often use Pureone.
Good job with the PureOne. The only Fram I use is the Extended Guard. Extra Guard, also known as Orange Can of Doom, Tough Guard, and High Mileage filters have shabby construction materials. You might want to look at the Oil Filter section to see some pictures of what the innards look like.
To answer your question though. Most oil filters today can do 6-10k miles with relative ease, for a standard 3,000 mile change you can pick just about anything on the shelf and feel comfortable. If you choose to do extended drains, 10k+ miles, then you should consider some of the higher end filters, Bosch Distance Plus, Fram Extended Guard, Royal Purple, Amsoil.
The more important question in my opinion is why are you only doing 3,000 mile OCIs? 6,000 is the new 3,000, unless otherwise required by warranty.
