I just found it odd that my oil started getting darker. G was stock other than air filter.

Im not a mechanic but my only explanation about that since you change your filters to K&N you actually increased the airflow therefore an increase in air flow = increase in combustion in the chambers equates to generating more HP and more heat inside the engine causes the oil to burn faster thus its more darker.

More air + right amount of fuel injected = More Combustion= Inc HP = more fuel efficiency.

But nothing wrong with that in fact my mechanic told me it just means your car is running more efficiently when your oil becomes darker in time for your scheduled oil change.

To me it made sense.
