Hey everyone... just hit a little over 1000k on my Strom. Did first oil change with filter at 280 miles and filled with Castrol start up 10W40. I just bought some Mobil 1 15W50 Full syn and was debating whether or not to change the oil filter as well. I was going to take it off and let it drain out as best as I could. The first change had absolutley no signs of metal particles or shavings, everything looked really good. Just wanna get some input from some of you on your thoughts about the filter change. The manual says to keep it on, I would change it for sure if I had seen any metal on the oil plug. Thanks for your input!!
