I've ordered a sampling kit. . . how often do you guys who have oil bypass kits. . . such as the amsoil kit test your oil? how often do you replace your filters?

Ihave the dual remote bypass filters, which relocates the full flow filter as well, and i just started having my oil checked, i had one at 4000 mi and 9500 mi on the oil with 1 full flow filter change, and my reports were almost identical. as far as when to test, i'm not sure, im going to have mine checked every 5k., i think that i'm going to still replace my full flow every 5k, and the bypass every 10k.

JASON: Your dual remote bypass filters are working well and keeping insolubles low. Wear looks great too, so we see no reason to change the oil or the filter media at this point. You ran this oil a lot longer than the last and the engine didn't even notice. The TBN was 10.2, loads of active additive left in the oil. 1.0 is considered too low a reading. The viscosity was mildly low but no fuel, water or anti-freeze was found that would have caused a shift. It's not hurting anything. Air filtration (see silicon)was fine. Check back to keep an eye on wear. Great engine!
