Lucas Oil on extended drain and base oil
I have had Mobil Delvac and Shell Rotella and my TBN always gets low. Apparently according to Kevin my cylinder kits are tight since I'm not consuming enough oil to add make up oil to compensate for my TBN. I hear that Lucas has a great oil for maintaining a high TBN. They also tout their oil is great for extended drain intervals. Anyone had any experience using the OPS Eco-pur, extended drains and intervals? I tend to change my 10" @ 25k miles and my extended drain filters every two intervals. Any help will be appreciated.
Is this a worthwhile discussion?
