that brings up another point we can discuss.


FL1HP oil filter Relief Valve Open (psi): 22 psi

FL1A oil filter Relief Valve Open (psi): 11-14 psi

how much of the oil is filtered each time it passes through the filter?

How many times would 5 qts of oil have to pass through the filter for all of it to be filtered at least one time?

Relatively easy answers;

Far less than you might expect and quite a few.

If you want full filtration then this is the filter you want, click here => Jomar Pro filter

Before you buy another Fram filter you ought to take a look at this 9 minute video. If you buy anything other than a WIX or a NAPA Gold — you deserve what you get and what happens to your engine.

... and who makes the Jomar filters? I am told Baldwin does, and they make the Moroso filters as well (which is what I have always used). At least, that's what I've been told.

I honestly don't know Patrickt. You could very well be correct.

Irrespective of who builds them, I would not use them as a daily driver sort of filter. They are excellent for picking up those small particulate contaminants that we all miss during assembly. After a short period of time I change them out for a WIX. They are only a last effort to insure internal cleanliness incase we/I inadvertently missed something.

Without the internal bypass if you use the filter for an extended period of time and it plugs up with contaminent materials you could starve mains, rods and other expensive pieces of the oiling they need to survive.

Take everything with a grain of salt. Although the Fram filter is garbage, he is comparing a Napa Gold filter with a Purolator standard filter. Not exactly apples to oranges. He should have used a Napa Silver filter as it is a lot more equal to the Purolator cheapie line, or used a Purolator PureOne filter, which is their top filter for standard use.

Years ago when I repaired cars, the boss used to use these Grease Monkey filters. They were cheap. We opened one up and there were shreds of newspaper used in the filtering media. You could still read the writing. They all went in the trash and we switched to ACDelco filters, which are/were rated pretty high at the time.

Those pressures you list are differential pressures between the inlet and filter outlet, not your regular oil pressure. They are supposed to relieve if your filter becomes clogged. That being said, you will filter 100% of the oil as long as your oil filter doesn't become clogged (to the point of your listed differential pressures).

Here's a good explanation of how a bypass valve works - to allow oil to flow to the engine when oil is too cold to provide adequate flow through the filter, or when it's plugged up.

Under normal operating conditions, the by-pass valve will not be open. When the by-pass valve does open, the oil flows directly to the engine to prevent oil starvation and damage to the engine components. Each by-pass valve is set to open at a predetermined pressure differential.
