Cars that come factory filled with 0w20 have oil change lights calibrated for 7k+ OCI because 0w20 can only be made using full synth or at least a blend, no dino oil can reach that grade. If you put in 5w20 dino oil, then those cars are easily running 2-3k past the oil's life before the maintenance light turns on.
I agree mostly. However, OP puts PYB 5w-20 which is a quality oil, so it should be fine if the MM trips below 10k miles. Remember, Honda used to spec 10k for normal service. On the other had, I’m not too sure about those Fit which can trip between 10-15k....
