Just ordered some Auto-Rx to use in my 97 F150 and my wife's 96 Outback. What Brand of filter do you guys recommend? I currently use a Pure One on both vehicles. Are they compatible with Auto-Rx?
I used PureONE on my Mazda for 3 cleans. I wouldn't use it with RX after this test as it appeared to restrict oil flow too quickly (noisy lifters a dead giveaway). Maybe something not quiet as good could be better IMO.
