Noticed the same with my car. the filter simply started turning as soon as I put my hand on it. Of cource the filter was some noname brand the prev owner put on, so I don't know. But the filter's I use are Donaldson filter with you get at Napa, and they are simple minded, has numbers at each 1/4 of the filter, you snug tight, and the number you see minus 1 is where you tighten it up to. I use these on the buses and other cars we have, no problems with filter lossing off. Also I don't use oil to lube the seal, I use grease, makes it alot easer to remove and not fight with a seal stuck to the base.
