Just purchased 2008 Scion XD for son. I always change my own oil. Appears that Scion XD 1.8 liter uses a paper cartridge oil filter rather than a traditional spin on filter. Do i need to get these from Toyota/Scion dealer? Is it simply a matter of unscrewing a metal housing and replacing the paper element? Is is easy, messy, etc. Picking up the car in 3 days; just curious. Thank you.
