I am new here to the scene. Was wondering what kind of oil do you guys use and how often do you change it? I had a Lexus IS300 prior to the FX35 and I used Mobile One Synthetic Extended Performance 5W30. I would assume that it would still be good to use in this. Also I changed that oil in the Lexus every 10K miles since it was good for 15K. Should I change every 7.5K like the maintenance interval says or go for 10K? Thanks for any advice.
