Hello everyone. My new Amsoil 5w-30 OE oil and Amsoil oil filter are coming tomorrow. I will be replacing Smitty's Super S 5w-30 and a Puralator Pure One. How do I cut open the Pure One? I have never done that before. I do not have any power tools. Just a Kobalt hack saw and Leatherman Wave multitool. I have a B&D workmate I can use as a vise. Thanks for the help.
