I purchased a fram ph7317 filter & 5w-30 castrol oil on 5/9/14 from autozone to do an oil change for my '06 Toyota Tacoma regular cab prerunner. My truck was fine until 6 months & 3k miles later, on 11/7/14, when I experienced a failure such that the filter came off my truck going 30mph & oil spewed onto the road. I pulled over about 200 yards after the filter came off just as the oil check engine light came on. I found the oil filter on the side of the road. The gasket was attached in fine condition, & neither face nor body looked deformed. The filter had minor scratches. My father came with tools & oil. The car's male threads were good. Assuming I erred & forgot to fully tighten the filter, it loosened over time, & its condition, I cleaned then threaded the same filter on & snugged it down with a wrench. I filled the engine with oil. My father was watching the filter area under the car for dripping oil while I filled, but there was none. I idled the car while my father & I checked for dripping oil but there was none. At this point, it seemed reasonable that the filter would not come off & oil would not leak. As a precaution, my father drove behind me. I started the car & made a u-turn in the road. At some point in the turn, the filter came off so I immediately turned off to the side of the road. The oil filter was crumpled. It is of my father's theory (he is a mechanical engineer by trade) & I that the filter failed causing pressure to build-up. This pressure build-up caused the filter to unscrew itself. The male threads on the engine side were good. I have since installed a bosch filter with castrol oil & the truck drives fine. The filter was not double gasketed. Even if it were, there would have been oil leaking when I idled the truck. It was not fouled oil, because the oil was replaced. It was not an improperly tightened filter, because the oil filter failed catastrophically almost immediately after driving off & there was no oil dripping during replacement or idle.
