Mobil1 flashpoint is generally strong. The type of driving determines whether there is cause for concern or not. At that mileage (10k really), seeing iron in the mid to high twenties on sho's is pretty common, so i am not seeing issues there. Tbn, fuel, K, Na, insolubles, silicon, etc all good.
My concern really is the lead and the chromium. Hopefully one off, may be due to additives in use etc. Still low level but worth watching. Maybe the filter just was out of capacity, IDK. I def would not go that long on the fl500s filter. 5000-7500 MAX even if all highway. Suggest purolator boss for best filtering. Has shown excellent results in extended use.
