Bypass oil filters
Ralph Wood
There have been some interesting articles in trucker magazines about
extended drain intervals using big roll paper towel oil filters to keep the
oil clean. These filters have been used for many years but are finally
getting some much deserved attention. Southern Motor Cargo, Mar 1995, p
8 - Southern Motor Cargo, Oct 1994, pp 25-26 - RoadKing, Oct/Nov 1996, p
28
As many of you know Luberfiner and Fleetguard uses ground up newspapers in
their best bypass filter elements to fit the Luberfiner housing.
A truck with a bypass oil filter now has over 800,000 miles with no
measurable wear on the Detroit series 60 425 HP. It uses Shell Rotella T
15-40 and is being studied by Shell Oils Westhollow Research Center. I has
had 2 oil drains since new. It is a 90 Pete 379. Shell and Covington Detroit
of Nashville will inspect it again at 1,000,000 miles.Shell uses these
filters on their offshore rigs
You might want to look at the following North Carolina State websites
about bypass oil filters.

Luberfiner also used wood chips mixed in with the newspaper. I seem to
remember some filters using Fullers Earth as the filter medium.

Fleetguard also uses wood chips. I don't know what function the wood chips
have. About 20 years ago I cut open a filter element that used cotton waste.
I found some cotton twigs and a few seeds along with the cotton. I pulled it
out of a Luberfiner housing but can't remember what brand it was. I don't
know anything about the Fullers earth.
The Army National Guard is using big portable systems that take 24 rolls
of Bounty or Scott big roll paper towels. They hook up to a Abrams tank
circulate the oil until it is clean unhook and move to the next tank or
other equipment. They can squeeze the oil out of the dirty rolls of paper
towels and toss the paper towel pancakes into a 55 gallon drum to be
disposed of. They can hook up to a fuel tanker and filter the fuel as they
are pumping it into a tank or other piece of equipment. The 500 HP rated
diesel filter uses 2 rolls of big roll paper towels. The oil must travel
down through 22 inches of paper at about 1/2 gal per minute. The clean oil
then goes to the oil pan. The same as a Luberfiner. Carroll's Foods Inc of
Warsaw NC uses them on 100 over the road trucks to eliminate "routine" oil
changes but most are on large marine engines. Imagine 8 12 V 71 Detroits on
one crew boat (John E Graham and Sons of Morgan City, LA)
The Peterbilt 379 mentioned in the earlier post belongs to owner/operator
Randy Rogers of Gallatin Tennessee.

Also used in some brands of kitty litter, I believe.
