Greetings all....excellent info you have here, I am learning a lot. I have an '03 honda insight and is due for its first oil change at 7500. There after I intend to change oil every 7K and change filter every other (14K) oil change. Given that, I was intend on using M1 0w-20 w/ an M1 filter. However, I'm still a bit undecided on which filter to use. I would have no problem dishing out the bucks for an extended change filter that offers both good filtration and flow if I can find one to match the insight. THoughts and suggestions are much appriciated thanks.
