A post in the oil section has me tossing and turning at night with fear and loathing. It's possible my Nissan OEM filter is a FRAM. The Nissan filter for my '92 Maxima has a part number of 15208-55Y00. When I installed it, I glanced inside and noticed it has the plastic kind of button at the far end. I'd buy another one and cut it open to look for cardboard, but the **** thing cost me $10CDN. If I find out I've paid $10 for a FRAM.....ARGH!!!!
