First oil change coming up on my 2009 Scion xD.

[CXTKRS1]

The car came with two free dino oil changes from the dealer and now I'm approaching the 15K mark so it is about time it perform my first oil change on the car. I was wondering who actually makes Toyota oil filters, I'm debating as to whether keep using Toyota filters or switch to Purolator which is the brand I normally use. Viscosity from factory can be either 5w20 or 0w20, currently 5w20 is being used and would I see an increase in fuel economy if I switch to 0w20? OCI is gonna be set around 10K and I was wondering what oil would you recommend for such a long OCI?
