I just changed mine for the second time. I did the 600 mile change and now I'm at 2300. I was going to to do it at 2000 but got too busy. I'm running Mobil 1 10-40. Nothing special, and no problems at all
. I have changed the filter both times (suzuki brand). Just can't see not changing the filter every time. That goes against everything I was ever taught about vehicle maint.
