i was curious did purolater improve their quality yet or are they still building filters that tear? I know most here stopped using them but it would be nice to know that they are doing something to improve the quality of that once liked oil filter.. I am in an oil filter buying group and i was asked this question by another shop that wants to go back to them because he has signs he took down and has no signs made for the Wix we are using now but like all of us he won't use them unless their is a quality improvment and just get new signs made up saying Wix.
