I change the oil every 3-5K so the FF gets swapped every third oil change and I Blackstone Report is done once a year at the min. I only drive about 8-9K per year. I keep a log book in the center console. I have every filter/fluid change, brakes, brake fluid flush, trans flush, tire rotation everything I have done to it. If I didn't write it down I would never remember!! Also the ONLY filters I use in all my vehicles is WIX filters, they are always near the top or are at the top of every filter test I have ever seen.
