And THAT, David, is why I'm not interested in bypass filters. You do get near-virgin oil in the engine at all times, but there's nearly zero cost savings over just using extended drain intervals. Changing the TP every 2.5k and adding a quart would be somewhat of a nuisance to me. I would consider doing this if I bought a vehicle new that I wanted to keep for 500kmi, but otherwise, it's not my cup o' tea.
