ProtxLTM (protects-all) bypass oil & fuel filters maintains the functionality of the fuel injection system, piston rings and bearings by effectively slowing down the chemical process of oil oxidation, maintaining oxidation stability, and by filtering particulate down to 5 microns.
What is meant by the term “oxidation stability” and why is it important?
Oxidation stability is a chemical reaction that occurs with a combination of the lubricating oil and oxygen. The rate of oxidation is accelerated by high temperatures, water, acids and metal catalysts such as copper and iron. The rate of oxidation also increases with time. The service life of a lubricant is therefore compromised with a combination of increases in temperature, moisture, acid formation and oxidation catalysts. Oxidation eventually leads to dangerous increases in the oil’s viscosity and deposits of varnish and sludge on engineered surfaces compromising the lubrication boundary.
“The presence of wear metals alone can cause oxidation rates to increase to five (5) times the normal rate, while the presence of water can increase the oxidation rate ten (10) times. Combined, water and metal catalysts can increase the oxidation rate fifty (50) times or more.” Ref USA National Tribology.
From the above statement it is clearly seen that oxidation is the main factor affecting oil service life. Existing spin-on and centrifugal oil and fuel filters cannot effectively slowdown the oxidation process. This is why it is a commonly accepted practice to change engine oil at a mere 250- 500 hours. The inability of existing filtration to remove oxidants and slow down the oxidation process leads to accelerated engine wear, reducing engine life, increased repairs, down time and high carbon emissions.
Example – Caterpillar C32 ACERT 1600HP Marine Diesel Engine.
ProtxLTM filtration is used on a tugboats Caterpillar C32 ACERT 1600HP marine diesel engine. Prior to fitting ProtxL P1600 filters, engine oil and filter were changed at 500hour periods. Once a ProtxL P1600HP had been fitted, the customer using progressive 250hour oil analysis was able to confirm the ability to run to 3,600 extended engine oil hours. This customer is now enjoying previously unimaginable operational cost savings.
