ah, controversy! i can tell you that i have pumped oil thru several of these til the cows came home, and they never solidified. to me, that's a defective one, and it ain't going in the engine. had a couple that the aluminum plug in the side was installed improperly and leaked. of course they aren't going to admit any fault. and why were they pulled off the market so long if there was no problem? hmmm.
