if you want to know how crappy a fram is. cut one open after using it and compare to a WIX or purolator filter. better yet here a pic of some frams. most people hate fram becasue they have cardboard endcaps and the media to filter is very small.

The size of a filter has NOTHING to do with it's filtering capability.

Only two (2) things are important: FLOW and FILTRATION.

REMEMBER, ... DIRT IS ENEMY #1 !!!

Don't be a tightwad when buying oil or filters. As with almost everything else that you buy ... the better products cost more. You guys spend $100's and $1,000's on your engines. Don't kill them with cheap oil and filters.

You're spreading the oil pump output pressure over a larger area. This lessens the time the oil filter bypass valve is open while your engine oil warms up to the point it will start being filtered.
If you double the size of the filter medium, you increase the effectiveness of filtration by reducing the speed of oil through the medium. Its efficiency is improved because the reduced differential pressure allows smaller particles to be trapped, instead of being forced through.
If I'm trying to push 10 gallons/minute through a filter area of 100 square inches, there's gonna be a certain pressure on the medium. If I then double the size of the filter to 200 square inches, the pressure on the filter medium will be half, with the same flow rate.

HowAboutThis,

Ummmmm ... How about "no".

As a vehicle owner you should look for an oil filter that provides the best possible balance of:

(1) efficiency, (2) long service life, (3) capacity, and (4) high flow capabilities.

- efficiency is a filter's ability to trap contaminants
- Service life is the period a filter allows proper oil flow
while trapping and holding contaminants
- capacity is the amount of contaminants a filter
can hold without loss of oil flow and filtration

Oil filters need good efficiency and good capacity to protect engines.

Those with poor efficiency fail to trap a significant portion
of particles large enough to damage the engine.

Those with poor capacity fill quickly, and once filled, allow dirty oil
to bypass the filtration media, circulate unfiltered, and damage the engine.

Proper Oil Filter for Synthetic Oil

When considering an oil filter for vehicles using synthetic oils, you should use a Synthetic Engine Oil Filter that is specifically designed for the advanced filtration needs of Synthetic Motor Oils.

I totally agree.
That's why I get the best "(1) efficiency, (2) long service life, (3) capacity, and (4) high flow capabilities" by using the biggest oil filter I can get.

Depends on application, sound research and so many other factors.

"why is my firm designing nano-technology filter systems for the military?"
Beats me, Bud. Probably because there's money to be made. Is this "nano-technology filter system" applicable to the current subject matter, i.e vehicle oil filtration?

alot of people like big oil filters because they can add a QT more of oil. as far as filter better I dont know but would filter longer than the smaller filters out there.

Well. If DanK and HowAboutThis are right, they sure would be able to hold more dirt and stuff. I think so, too. That's why I use the WIX equivalent of the Fram PH8A and Mobil1 5W-30. No problems so far on my 4.7L. And I change oil and filter every 3000 miles.

Jimmy D why put synthetic in your truck if your going to change it out at 3,000 miles. might as well stay with dino oil. that M-1 can stay in there well past 7,000 miles. your wasting your money this way.

It has everything to do with piece of mind, and nothing to do with oil manufacturers' claims. I tend not to believe them anyway.
Admittedly, the new SM spec "dino" oils are much better than the previous SL spec at minimizing varnish and sludge, but I still prefer a true synthetic. Less emulsified oil caked to the filler neck and gumming up the PCV valve (a common problem in the 4.7L engine).
Yeah it's more expensive, but like I said - piece of mind.

Let's use a different analogy: the air filter. Now this is gonna be different than an oil filter, because in an oil filter, oil gets forced in by a pump, and there's a pressure-operated bypass valve. In the air filter, the air gets pulled in by a vacuum, and there's no bypass.
Anyway, take your basic stock air filter. It's a particular size and shape paper filter. That size and shape will pass air at xxCFM, and hold a certain amount of dust and dirt before the engine starts to have difficulty inhaling. Now, say we just installed an air box that let you put in an air filter twice the size of the stock one. Suddenly your engine is sucking air through a filter that will pass air at xxCFM X 2. It breathes much easier through that oversized paper filter (a good thing), and your air filter's dust and dirt capacity just doubled (also a good thing).

I use the Amsoil bypass oil system and amsoil filters. the amsoil bypass system adds a second filter and 3 qts of oil. You can't get better protection than that and i only change my oil every 25k miles. my dakota has had only 6 oil changes and it has 165k on the odometer. still purrs like a kitten and pulls like a locomotive. Amsoil bypass system and amsoil filters is the only way to go.
