Hmmmmmmmmm.... Fram has 193 sq inches filter material and Motorcraft has 400 sq inches. I know what I will buy!
High density filters doesn't always mean good flow...more than likely this means it has more pleats and is packed tighter decreasing flow properties...I see this everyday with air filters in A/C units...people go to Home Depot or Lowes and buy themselves an expensive pleated filter and then they can't figure out why their system doesn't work as well as it used to when they have cut their velocity in half. Unless their surface area for flow is twice what they need they run the risk of doing serous damage to the system.
I think that is 2 different things. Air will compress behind too much filter material and liquid cannot be compressed. As long as the oil pressure remains the same, the filter with more surface area will "filter more" before the bypass opens inside the filter.
Motorcraft Long Lasting FL-1A Like the Purolator Pure One, this filter cartridge features a very large element surface area (400 sqin), but with many pleats (64). This packs the filter together rather tightly and may restrict flow somewhat
I would place more importance on flow with filtration a close second. It's finding the filter that does both well...be it oil OR air.
I like the filters that you could get in the '60's and '70's that were basically metal cans that you put a roll of toilet paper in. Just change your oil a pop a fresh roll into the canister. Hmmm, maybe I could design something that uses old pantyhose! :bananaman
All I use is Motorcraft. I trusted them before, but it's nice to have a chart to compare them to the other options out there. Now we need one for air filters..... Everybody knows there is gonna be contraversy over air filters. Preston
Speaking of the TP filter, here you "go" ................. http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&rd=1&item=2494737301&category=42606&sspagename=WDVW
My family and I have used Motorcraft oil and filters on all of our vehicles forever and have never had an engine failure. Sam
