First oil change coming up on my 2009 Scion xD.
 

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?

look in xD drivetrain and power.

I'm not sure who make the Toyota Filter. But I do know that they are either made in Japan or Thailand.

I beleive the 2zr engine uses a cartridge filter instead of the canister.

Does anyone know who makes Toyota OEM synthetic oil?

I read on another site that Nippon, and Mobil are the suppliers of all Toyota motor oil in North America.

I couldn't find the exact thread, but above is a link to the site if you want to look. There's more on their forum than most people ever care to know about oil.
