By Pass Oil Filter Extends Engine Life and Reduces Maintenance Costs

By Pass Oil Filters extends engine and oil life by reducing wear, rust and oil degradationPRODUCT DESCRIPTION
The AMSOIL By-Pass Oil Filter provides the best possible filtration protection against wear, oil degradation, rust and corrosion. Working in conjunction with the engines full-flow oil filter, the AMSOIL By-Pass Filter operates by filtering oil on a partial-flow basis. It draws approximately 10 percent of the oil pumps capacity at any one time and traps the extremely small, wear-causing contaminants and water that full-flow filters can't remove. The AMSOIL By-Pass Filter typically filters all the oil in the system several times an hour, so the engine continuously receives analytically clean oil.

Reduces Wear
Approximately 60 percent of all engine wear is caused by dirt particles in the five to 20 micron range. These particles can get inside the precision clearances between engine components and cause severe damage. While full-flow oil filters generally stop contaminants no smaller than 25 to 40 microns, the AMSOIL By-Pass Filter effectively stops particles down to one micron in size, substantially reducing engine wear.

Prevents Oil Degradation, Rust and Corrosion
Water enters motor oil as a combustion byproduct or as a condensate and can cause extreme engine damage, causing metal surface rust and corrosion that increases friction and wear and deteriorates the close-fitting tolerances between engine components. In addition, water reacts with other contaminants to form corrosive acids and sludge, which also damage metal components. The AMSOIL By-Pass Filter removes moisture and condensation, reducing the risk of oil degradation, engine rust and corrosion.

Extends Oil Drain Intervals
Because the AMSOIL By-Pass Oil Filter removes water and particles down to one micron, it significantly increases the time oil can safely be left in the engine. In fact, engines using AMSOIL Synthetic Motor Oil and an AMSOIL By-Pass Oil Filter routinely show much lower rates of engine wear even when the oil is used for significantly longer drain intervals than engines using conventional products and conventional oil drain intervals.

Dual Remote Filter System
The AMSOIL Dual Remote Oil Filtration System converts an engines' full-flow oil filter system into
a full-flow/by-pass oil filtration system by attaching an AMSOIL Full-Flow Oil Filter and AMSOIL
Spin-On By-Pass Oil Filter onto a remote mount. The Dual Remote System provides superior filtration efficiency, increased oil capacity and improved oil filtration accessibility.

Trucker Saves Over $15,000 on Oil Changes

"That could be the difference," he says, "between staying in business or not."

MIDLAND, MICHIGAN -- Independent owner-operator Norman Stanick used AMSOIL Synthetic SAE 30 Heavy Duty Diesel Oil and an Amsoil By-Pass Oil Filter in his 1987 Caterpillar 3406 engine since the truck was new (after breaking in the engine with another oil) until he sold it seven years and one million miles later. He performed four oil changes during that period, basing his extended oil drain decisions on the findings of used oil analyses performed at 50,000 mile intervals.

After 848,000 miles, Stanick pulled the pan to fix a water leak. He decided to take a look at the main and rod bearings. He was there when the mechanic pulled them out. "There was not a shiny spot on any of those bearings. They measured out at new part measurements," said Stanick.

"I saved between $15,000 and $18,000 on oil changes. That could be the difference between staying in business or not."

Stanick now owns a truck with a 1994 Detroit Diesel Series 60 425 engine. He uses AMSOIL Synthetic 15W-40 Heavy Duty Diesel and Marine Oil in it. He continues to use oil analysis and changes his oil at 250,000 mile intervals.

"Let me tell you a story. My son and I drive team. We were in California pulling a 43,000 pound load. It was three in the morning and my son was driving. Suddenly, all the dash lights came on.

"We pulled over, shut down the truck and looked under the hood. A filter had come loose and all the oil had been pumped out of the engine. Every drop.

"Now that's a $25,000 engine that we ran without oil! But once we got the filter fixed and put some oil back it, it started right up and has run perfectly ever since. I'm sure AMSOIL saved my engine.

"I have no question I can run this engine two million miles with eight oil changes. People don't believe me. They tell me I'm crazy. I just smile all the way to the bank."
