I sometimes use pure one oil filters in the summer months but am afraid to use them in the winter.. I cut new filters open from time to time and noticed the pure ones media is so close together i am worried the oil when thick can't get through and the bypass valve opens and don't filter the oil until warm.. With all that media so tightly together im pretty sure it must filter ok but what about oil flow??
I tried to post this in the oil filter section but could not get it to post there..
