Plain Old Oil Filters
  • There is NOTHING you can do for a reciprocating engine,
  • (Car, Truck, Tractor, OR
  • Expensive airplane engine)
  • That is more beneficial than a plain old oil filter…. PERIOD!
4
Oil and Engine Wear
  • All moving parts in a reciprocating engine are separated by a film strength of oil which is .001” thick or 20 microns.


  • The more efficient the oil filter, and the more particles down to 20 microns that you remove from the oil flow, the slower the engine wears out.
5
Oil Screens
  • The original oil screen was never
    designed to filter oil.  Its sole purpose is to tell you when your engine is making metal.
  • Commonly used words for oil screen
    • Rock catcher
    • Rock strainer
    • Catches only objects with part numbers
6
Limitations of Screens
  • A Screen, any screen, regardless of how small the wire mesh is, has no dirt holding capability whatsoever!
    IT IS PHYSICALLY NOT POSSIBLE.
  • Plain Old Dirt
    [Silica, Sand, Dust, Grit, Dirt, Glass Beads etc]
    is what wears an engine out.
7
Not Having an Oil Filter
  • Look at all the airplanes that fly into Sun N’ Fun every year without even an air cleaner! These planes sit in the worlds biggest cat-box with the worlds most expensive vacuum cleaner on their nose.
  • Where do you think all this dirt goes?
    Into the engine oil of course. They effectively have lubricated sand paper running through their engines.

Filter Efficiency
9
Frequency of Oil Changes
  • The frequency of the oil changes means little if you do not have an oil filter in the lubrication system.  It doesn’t matter if you change your oil every 10 hours; if you get dirt into the oil right after the oil change, it will circulate until the next oil change.
10
Adding VS Changing Oil
  • However, we hear comments like “My engine leaks so much and burns so much oil, I never change it, I just keep adding more.”
  • Most likely, this operator has never done an oil analysis.  If he had, he would be shocked to see how high the silica content and wear metals were in his oil.
11
Oil Velocity & Surface Area
  • Oil filtration is all about the velocity of the oil flow and the surface area of the filter.
    FRAM Surface Area VS Engine Oil Screen
    641 SQ IN 31 SQ IN
  • There is 20 times as much surface area in the FRAM
  • The reason oil filters are pleated is to maximize the surface area so you can slow the oil down to a point that the dirt and wear metals can be removed.

P&W R985&R1340 Oil Flows
13
P&W R1830 Oil Flows
 Maximum flow rate is 14.4 GPM
14
P&W R2000 Oil Flows
Maximum flow rate is 18.5 GPM

The AIRWOLF “Gorilla” Kit

The AIRWOLF “Gorilla” Kit
  • Our Gorilla Kits were designed around a FRAM NASCAR racing filter that has a 20 GPM capacity.
  • The largest Champion oil filter has a maximum flow rating of 12 GPM , with 50W oil.  Our competitors claim 20 GPM flows on the Champion.  How do you force 20 GPM through a filter that can’t handle more than 12 GPM ?

Oil Filter Design

FRAM Filter Points
  • 98% Efficient at 38 Microns
  • 20 GPM flow rating
  • 641 sq/ inches of Hi Flow/ High Efficiency media
    [4” Wide X 13.5’ Long]
  • Internal pressure relief valve
  • Internal screen covers oil bypass valve
  • 400 PSI Burst Rating
19
Oil Filter Placement
  • You always filter the oil at its hottest point, right after it leaves the engine.
  • The hotter the oil is, the easier it is for the filter to get rid of the dirt. Imagine dirt in THICK cold molasses and dirt in THIN hot baby oil.  It is far easier to filter dirt from hot, thin oil.
20
Added Benefits to Filtering Oil Right After It Leaves the Engine
  • Keeps your oil cooler from becoming a trash collector.
  • In the event of an engine failure, the metal will be trapped immediately in the oil filter, minimizing the damage to the rest of  the engine.  A simple piston failure may no longer mean a major rebuild.
21
Highlights of “Gorilla” Kit
  • Easiest installation of any kit on the market
  • Clamps around engine mounts from 1” to 1-3/4” OD
  • Uses bulkhead fittings instead of NPT fittings
  • Allows 360° orientation of fittings and hoses
  • Viton O-Rings under compression, keeps it leak free
  • Can still use MIL6000 hose if desired
  • Ready for Airwolf chip detector (soon to be released)
  • Will be able to manifold (2) kits together for 40 GPM
    flows, to work on R2000 & larger engines
