Oil filter question

Been using Fram PH16 oil filters in my XJ and YJ for years probably because they are what the local parts place sells. Anyways, took a couple of old used ones apart recently with a filter cutter for inspection. The spring for the plastic bypass valve seems kind of wimpy...it only takes less than 10 lbs to fully compress it. However, by comparison, the spring taken from a Champion aircraft oil filter doesn't hardly begin to compress with 10 lbs of weight on it. Just wonder how much oil the Fram filter is filtering and how much it may be bypassing. Anyone have any input on this? Thanks.

Normal oil pressure on a Lycoming is about twice that of a 4.0L. And the oil viscosity is higher.

Fram isn't what it used to be. Use a Wix if you want a quality filter. In addition to a poor bypass valve, the Fram anti-backflow seal isn't worth a hoot, either. I used to have lifter clatter at start-up with Fram filters. That problem completely ceased when I switched to a different brand.

Not much (Quality filtering going on there). If you search Fram filters on here you will see that we have pretty much voted them off of the island!

You can get the Wix filters at most places as well and they use a coil style by-pass spring rather than the leaf. I cut open a Baldwin this week, it also had the coil. And of Course the Amsoil EAO filter has a coil as well.

The WIX can be grabbed off the shelpf at most places. Also Carquest & NAPA Gold filters are made by WIX, but I have not opened either of those to verify the coil spring.

What concerned me most when I opened the Fram filters was the cardboard end caps they use.

Purolator Pureone is what I run. I run the one for a Mustang 5.0 on my Jeep and I can hold about .5 to .75 qts of extra oil. My TJ had drainback problems with Fram filters because their anti drainback valve blows. Purolator, Wix and Mopar filters dont have this problem so I stick to them.

I've heard nothing good about fram. The worst out there from what i read. I guess they are made of cardboard inserts and have platic valves that let dirty oil leak back into the pan. Not enough oil flow...so I think it'll up your oil pressure according to the sensor. Get a napa gold filter, also heard good things about purolator.

I run a NAPA 1515 made by WIX for NAPA the same filter the 5.0 mustang uses it'a a little taller for more filtering media, lot's of people run this filter on their 4.0 on this forum and others
you will neep a tad more than 6 qt of oil on your oil change so go ahead and get 7 qts!!

i remember on one of the last fram topics that supposedly cumins will void a warranty on any of the motors if a fram filter is used due to how bad they have gotten

i use purolator usually

I used to use Fram, but man, I watched too many youtube videos of filter reviews bashing Fram. I chose not to use Fram on my Jeep.

Now, I use the Napa Gold Filter P/N #51515 IIRC

I run K&N 3001s. They're a Fram PH8A equivalent but they're top notch quality. Every time I fire my rig up, the oil pressure is there instantly, instead of waiting for several seconds for the rig to build pressure.

Ford FL-A1 Works on the 4.0 Also I hear it's a Monster filter.

I used the K&N one before i switch to amsoil smaller filter but better filtration.

I put the same K&N filter on my g/fs 2000 neon and it held 1/2 qt more haha and weighed almost 3x the stock oil filter empty lol.

K&N 3001 PH8A='s Amsoil Ea015

Only time id think about using a fram is doing a motor flush or on somebody else's car haha.

Mobil1. The M1-301 like the PH8A, FL1 etc. Have never heard anything bad about them. Got 6 in a case from a guy on eBay, free shipping. Cheaper than local stores, including WalMart. Phil

I run the Puralator Pure One.

Good research numbers and the pricepoint is not much more than an "el-cheapo".
