Which filter media is best used for extended drains?Baldwin uses cellulose blend and I believe Fleetguard uses synthetic(Stratapore).My bypass setup is a Baldwin filter head #OB1305 and a Baldwin bypass filter#B164.I plan on changing both filters using 10,000 mile intervals with Shell Rotella-T 15W40 oil.I also plan on getting oil analysis every 5,000 to see if I can go further.Thanks Joe
