Anyone using a Gulf Coast Bypass filter???

I just bought a Gulf Coast 0-1 Bypass Filter...they use either the Gulf Coast filter or a roll of paper towels. I plan on using the latter, because at $2/filter...

I already have an Amsoil BMK-11 and EaBP-100 filter...not real pleased with it...the older BE filters worked better. And the filters are $40/each...

Anyone using one and how do you like it??

You are correct, the paper towels are inserted into a canister, the oil flows through the length of the roll (the center tube is plugged)...it's called depth filtration. A typical TP/paper towel filter are good to 0.1 micron in fitration...I have yet to find an affordable "spin on" alternative: the Amsoil EaBPs (which are only good to 2 micron) are $40/each, the Luberfiner LF7950 is (also a 2 micron filter) is $94, the only Baldwin/Fleetguard "bypass filters" are rated at 8 micron and 10 micron respectively. I am listing absolute numbers here, which is the 98.6% efficiency. Here are some links (sorry, seems when they had issues a month back, my post count went away...these are all www dot coms):

I know a bunch of guys running toilet paper filters (primarily Frantz or Motorguard)...they claim the paper actually becomes stronger when it is exposed to oil. Remember, there should not be water in your oil (just being funny), and if there is a little bit of water (a bad thing) the TP will remove it (without disentigrating). I have not heard of a single case where an oil system in good shape caused a TP roll to disentigrate...that's typically an old-wive's tale. And since the filtered oil is returned back to the sump, any stray particle that might potentially come off the paper would pass through the fullflow filter anyway. And FYI, most filters on the market are made of cellulose...a fancy name for paper.

In a bypass system, you only pull a small stream off, typically (as was already mentioned) under 10%. The bypass simply polishes the oil, it doesn't take place of the fullflow. I think I'm running right around a quart per minute at idle through the Amsoil bypass. You don't drop pressure to the filter, you drop the volume of oil...slow the flow. The slower the flow, and the longer the residence time in the bypass filter, the better (to a point). I'm running a 1/16" orifice in my Amsoil unit.

The Gulf Coast Filter website is a good read...while they offer their own filter, they are nothing more than a roll of paper towels with handles. The Oilguard filter is nothing more than a bunch of cotton string wound together...

I talked with Wix's engineers and was told they didn't make a standalone bypass filter/filter head??

OK, this is a "blank post" so I can link some pictures of my GCF...

Here are some pictures of a paper towel filter...these are supposedly one of the best forms of filtration...



That is the GCF compared to a Amsoil EaBP110...



This is the guts of the filter...



This is the orifice that restricts flow...I believe I read it is 5/64" and limits flow to 2 quarts per minute...I'll be custom making fitting with a 0.053" orifice to get flow down around a quart per minute...



This is the element (paper towels) in the holder and inserted in the housing...the oil flows the length of the element...basically parallel to the center roll.

Hopefully this helps...
