My most recent report from Blackstone. Drained 6 qts of Castrol Edge EP out and removed Motorcraft FL500s filter after a 6,420 mile run. Engine had 22,422 miles on the ODO at time of change. Six quarts of Castrol Edge EP 5W-30 went back in along with a Motorcraft FL500s filter. Next change will take place around 30k. I'm still debating whether or not I should have 7.5k or 5k OCIs. My concern, as discussed a lot about for this engine, is timing chain related issues. Also, I do not have anymore MC filters so I am looking to buy a better filter. One that can get insolubles lower than 0.3. Any suggestions?
