Engine wear is caused by dirt particles larger than 5 microns. The AMSOIL By-Pass Oil Filter removes particles as small as 1/10 of a micron, virtually eliminating engine wear. AMSOIL By-Pass Oil Filters filter all the oil in a six-quart system in about five minutes at an average engine speed equivalent to 45 mph.

PRODUCT 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 engine’s full-flow oil filter, the AMSOIL By-Pass Filter operates by filtering oil on a "partial-flow" basis. It draws approximately ten percent of the oil 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 5 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 smaller than one micron in size, substantially reducing engine wear.

Prevents Oil Degradation, Rust and Corrosion

Water enters motor oil as a combustion by-product or as a condensate. Water contamination of the motor oil can cause extreme engine damage. Water causes metal surface rust and corrosion, which increases friction and wear and deteriorates the close-fitting tolerances between engine components. In addition, water reacts with other oil contaminants to form corrosive acids, which also damage metal components. The AMSOIL By-Pass Filter removes water, 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 smaller than 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. That saves motorists time and money and helps protect the environment by creating substantially less used oil.

b. Data determined in a non-turbo gasoline engine with AMSOIL 100% Synthetic Motor Oil and AMSOIL Full-Flow Oil Filter.  Service life varies in other engines (turbo and diesel) and with other oils and filters.

NOTES:

1. Special adapters and hardware may be required for some installations. A universal mounting bracket is included with the kit, however, custom brackets may be required depending on your vehicle's equipment options or personal preferences in mounting locations."
