I am getting ready for my first oil change. I am using OEM because my dealer says warranty-blah blah blah. Anyway my original filter has the number 15208-FOD. I looked around and found most people are using 15208-9E000 and that is what my dealer says they use. I ordered 3 filters and crush washers from Factory Nissan Parts. I ordered part # 15208-9E000. When they arrived I got one 15208-9E000 and two 15208-65FOC. They( Factory Nissan Parts) tell me they are the same filter:thatswck:. WTF . Why is there so many different part #'s for the same filter? Anyone know?
