I've tried the search for what is the subject and it's way too broad. It returned 500 threads, most having nothing to do with the oil filter. And this was just a search in this forum alone. An explanation is when the page returns with the search results it states it cut off everything but the word oil, hence all the unrelated garbage I don't want. I don't have time or patience to search through 500 threads so I'm going to ask here: Is it necessary to change the oil filter with every oil change? I ask because my other bike says to change every 3rd time or 12,000 miles. Knowing that a slightly dirty filter cleans better than a new one, is another reason I ask. If I ask a Honda rep, the answer is automatic yes because they want me to just spend money. So I ask here to get a REAL answer.
