Changed my oil around 2500 miles with Mobil 5w-30 along with a OEM Filter.
Did a second oil change around 5500 miles but could not remove the oil filter due to lack of daytime light and could not get a good grip on the filter.
So i decided to leave the filter on and simply refil the oil as needed.
I do understand that both dirty and clean oil will mix and that the oil filter is still dirty and has less capability to filter contaminents from the oil
What I am worried about is if I created any pressure differences or pockets of air or anything harmful from this situation.
Can somebody confirm that this is nothing harmful or if it is.
