If I could find a PF 1177, I would use it on my truck because it has half again as much media as anything else I have cut open. I am using ST 3590's because they are cheaper and have almost as much media as STP, Purolator, Hastings, and twice as much as Fram.
Having bought them in AC, Fram, and Hastings boxes, I have mostly used Purflux 264A's in the canister filter in my Cavalier. Also one each of STP, Purolator, and now WIX. Still outraged over paying $5 to $8 for a filter with no metal at all in it, and still looking for a better deal. Fram is now selling their own, and I have to go out of town to find the $5 Purolator in stock.
