So, why would you think PureOne's bypass is set higher? To force oil through the filter?
What are the +/- 's of oversized filters?

I purchased this past July a Chevy 1500HD 6.0 gas truck. The first thing I did was ask about a larger oil filter. The truck came with the PF44, which is very small. The same truck in 2002 and earlier years came with the larger PF59. The parts guy said that they were using the larger PF59's on the 2003's for oil changes until they got a memo from gm telling them to stop.
I don't understand why gm wants to use such a small filter. Could it be part of the changes made in 2003 engines to prevent/stop CSK (piston slap)??
Anway, on advice from gm, I will be using this tiny pf44 in my new truck.

What about using the stock (small) size in the winter on a car that sees 4 to 12 mile trips? The smaller quantity of oil should get up to temp faster and boil off nasties.
I don't know what to say about silicon around here: The ground would be frozen and covered with snow, but there'll be sand on the roads which might more than make up for it...

The difference in the amount of oil from one filter to another as compared to the 5 quarts or whatever total is very small. A PF 52 has 77% more filter area than a PF 47, and if the media is the same, it should flow much more oil when cold. On a cold start up, I want all the flow I can get to the bearings.
I have a 89 F250 truck with 7.5L and am wondering if I should use this oversized filter:
2 quart version of the wix filter.
Wix part #51773.
(NAPA #1773)
The thread size and gasket size is the same, but the filter is almost twice as
long.
Same oil filter as for 89 f-700 with a 429 or a 370.

In my case I have an Aerostar which takes a Purolater L20195, but my pickup takes a larger L30001, and I found out the bit truck (F700) has an even larger filter that fits the pickup, an L40017. All have the same fitting size and all have the same relief spring pressure (8-11 psi), all have anti drain back valves. Even though the L20195 has a slightly smaller rubber o-ring gasket, I have measured and the L30001 fits the Aerostar gasket mounting surface. The only difference I am aware of besides can size (sure there may be different porosity of paper element) is the gallons per minute flow rate:
L20195 = 3 gpm
L30001 = 4 gpm
L40017 = 7 gpm
Now, as far as I can tell, that means more oil pressure will develop up in the engine where you want it instead of having a restriction just after the pump.
BTW, I got the flow rates for the Wix filters and they are 7-9 gmp for both the 4 and 7 gpms above, Part numbers 51515 and 51773.

Great info TallPaul! I currently use the Wix 51773 filters on my Jeep 2.5L Wrangler and my 22'Hammond Challenger 360 CI SBC. Both engines have remote mounted filters that take the FL1A thread size but there is plenty of room for the larger 51773 so I use them. I really like the 9 GPM that this filter flows as I don't think my 2.5L would ever go into bypass as it only has a 5 1/4 qt sump capacity.
