Used a Ac pf 1127 oil filter, K&N air. Driven hard,both hot and cold temps.
Low wear on a vis that is NOT recommended by Honda.
For example Fe averages 32.5 ppm so 21 is low.
Flow rate good with no problem cold starting,was slower to turn but not problematic. Fuel economy was not affected by the motor oil at all.
