Oil Filter Comparison

[FED 387]

Just remember regardless whose oil filter you purchase basically only 4 large companies make all of the oil filters in the WORLD for everybody--The Rank Group ---Mann-Hummel------Kuefner Filters----Parker Hannifin corporation--FED 387

Have used the NAPA/Wix non R filters for years with no bypass, Have seen the difference between using a filter with a 61 Micron and using a filter with 21 micron rating.

Did some research on oil filters a few years ago.

Micron rating on filter paper is an "average" opening size meaning there are larger and smaller openings.

Higher quality = tighter range of size of openings.

Screen filters offer a tighter range in opening size particularly those of medical grade stainless steel plus can actually flow more oil with less restriction.

There's a few HP there.

I have been using the System 1 filter for years with good results. I lost one engine due to an AC Delco filter collapsing. No more passenger car filters for me.

I’ve been using the System One filters for quite some time and have it on all of our engines. Just makes no sense to use a stock filter on a Race Engine. I like the idea of being able to take it apart and inspect the filter element clean it and put it back in

Joe, an engineer at the Sunoco refinery lab a few miles from my shop, tested filters & posted the results he got on a local board. Wix flowed more, and stopped caught more crap than the others. He was a customer of mine. I gave him one of my System1 filters. I used them, instead of cutting & throwing away the AC filters I had been using. I only used one Fram. Stopped that after cutting the first Fram apart. I was not comfortable with what it looked like.

Anyway, the spare System1 I sent with him did not flow as much as the Wix filters. I did not feel like I needed a flow restriction in my engine's oil system. I was running a dirt track Sprint Car every Fri & Sat nights then. Cheaper than throwing away two cut up Wix filters a week. I was disappointed in the test results. Never hurt any bearings with the System1. May have flowed enough.
