Amsoil Ea By-pass Filters
The Dangers of Soot

The combustion process in diesel engines creates soot. After fuel is injected, combustion occurs with soot as a by-product of the process, and the combustion particulates become trapped on the exposed oil film. The rings wipe the particulates into the oil and the fine particulates aggregate, increasing levels of soot in the oil.

Oil with dispersant additives will generally keep soot in the range of 0.002 to 0.5 microns in suspension; detergent additives prevent the build-up of sludge and act as an acid neutralizer, keeping soot in the range of 0.5 to 1.5 microns in suspension. These anti-wear additives work by providing a sacrificial chemical-to-chemical barrier. As the amount of soot suspended in the oil increases, the performance of these additives decreases.

Soot Causes Wear

As an oilís soot dispersant additive levels increase, wear reducing additives become less effective. This creates a direct linear correlation between wear and soot concentration; the higher the concentration of soot, the higher the level of wear. Todayís oil manufacturers are extending oil life by holding higher concentrations of contaminants, including soot, in suspension in the oil. They are also increasing fuel economy by reducing oil viscosity and oil film thickness, therefore reducing the critical contaminant size. This further necessitates the use of by-pass filtration, especially in diesel engines.

Quality Construction

AMSOIL EaBP Filters have a marine powder coated exterior. Their zinc-dichromate base plates increase rust protection, and are compatible with existing AMSOIL by-pass filter mounts. EaBP Filters have a nitrile HNBR gasket and an orange silicone anti-drain valve. The two stage pleated and layered cellulose/full-synthetic media has an efficiency rating of 98.7 percent at two microns.

EaBP Vital Statistics

AMSOIL offers three by-pass filters; the EaBP-90, EaBP-100 and EaBP-110. All vehicles and applications that can accept the AMSOIL BMK-11, 12, 13, 15, 16, 17 and 18 filter mounts can use the EaBP Filters. Per AMSOIL by-pass installation instructions, AMSOIL recommends by-pass filters be mounted as close to vertical as possible. The filters are equipped with an antidrain back valve in the event they are mounted at an angle.

Who Uses By-pass Filtration?

By-pass filtration comes standard on all heavy-duty turbo diesel engine applications from OEMs such as Cummins, Mack and many more. It has been available as standard equipment or as an option from OEMs like Caterpillar, John Deere, Case and others, but it isnít just for heavy-duty diesel operators. By-pass filtration is a valuable commodity for anyone that wants to extend drain intervals and prolong engine life. It is also beneficial to vehicles that are exposed to high levels of contaminants on a regular basis.
