I have a 2006 Mazda 6 w/ the 3.0 V6, The car requires 5w/20 oil and I am needing to know the best oil/filter combo to use. I am partial to Mobile 1 oil and filter but have heard for a 3-5K OCI that its useless, what is recommended? When is the best time to drain the factory fill, I have 650 miles on the car presently.
