I am planning my next oil change, as the lifters in this engine make some noise when it is cold.. so I will try switching to Mobil 1 or may be some other high tech motor oil, my question is what do you all use for filters? I have used Wix for years on the farm tractors, and all my other rigs, but may be that is a mistake for this engine. no point in putting in expensive oil and put the wrong filter in it. Also what about those bypass filters? I like the thought of not having to change oil quite so often. Do they work, or are there horror stories about them?
Thanks,
jason
