I used to be a oil freak and change out all the time at 3K or less new filter etc. Its just a plain waste of money but if you need it to feel good do it.
I never change my oil filter on my SC sled its there it sees zero dust, the oil is almost as clean coming out when it goes in. I do change oil annually but even debating on leaving that for 2-3 years. Oil debates are funny you can always go back to "10 million dollar engine spend the $100" but I am starting to believe there is no point! My truck I go 15,000 miles on non synthetic per the manfs reccomendations of which they must be conservative and people get shivers in the spine, I put 700 miles on some amsoil synthetic snwomobile oil and I should dump it every YEAR regardless?
Each to thier own, till i blow a engine from poor oil change process I am leaning towards just leaving it and not even messing with it anymore.
