I would be careful with the drain bolts. Don't just blindly dial in the torque value and go at it, you might end up stripping it. Hand tighten it using the smaller 1/8" ratchet (allows less torque) and apply light force to tighten it. Common sense approach comes in handy here. Then you can check with the torque wrench if you so desire. The filter housing uses a big ass nut that is easy to torque down but the drain bolt is so small, torquing it gets tricky.
By the way, 25nm seems a bit too much. I would double check that value.
