Ive been considering buying a case of Pennzoil filters at just over $2 each. They would be used on an 06 Subaru with the 2.5 turbocharged engine. Intervals are short, normally less than 4k miles. From what Ive gathered they are currently made by Purolator but at one time may have been rebadged Frams. I was hoping to see if anybody has pictures of a recent Pennzoil PZ37 cut open. Since the OEM filters are now Frams Ive been looking for a better value filter option. Any help will be greatly appreciated.
