What is Oil By-Pass Filtration?
A by-pass oil filter is an add-on oil filter kit that is far more capable than the standard oil filter on your vehicle. By-pass filters remove wear-causing particles down to less than a micron. Standard full-flow oil filters only remove particles down to 15-25 microns. The dense by-pass filter media slowly cleans the oil over about a 5 minute span, leaving oil almost as clean as it came out of the bottle. This significantly extends oil life and removes virtually all wear-causing particles. When coupled with long-life AMSOIL Synthetic Motor Oil, oil change interval lengths can be many multiples of regular oil changes. These systems add engine oil capacity which also extends oil life and contributes to cooler oil temperatures. Optional sample valves make sample-taking for oil analysis a breeze.
Rather than change oil at a set interval, use bypass filtration and lab analysis to scientifically dictate oil change intervals. Save time and money on oil changes, lower engine wear and reduce waste oil. These systems are especially beneficial to those who log big miles. We have systems available for cars, trucks and heavy duty applications. These durable systems can be transferred to future vehicles. Note that you may need to fabricate a mounting bracket for many applications. For more information or pricing on any of these kits, feel free to contact us.
By-Pass Filtration Systems Application Guide
Unparalleled Fine Particle Removal
AMSOIL EaBP Filters have an efficiency of 98.7 percent at two microns. At normal operating RPMs the EaBP Filter will filter all of the oil in a typical five quart sump in less than 10 minutes.
AMSOIL By-Pass filter elements have a filtration effectiveness rating of 98.7% at 2 microns. To illustrate how superior this is to the full-flow filter on the average vehicle, consider that an average factory oil filter might have an effectiveness rating of 85% at 20 microns. The slow-filtering AMSOIL By-Pass kit will clean an entire engine oil capacity in around 10 minutes at highway speed.
What are the Advantages of AMSOIL Oil By-Pass Filters?
- Filters out particles (less than one micron!) that regular oil filters can’t touch.
- Increases oil life by significant margin
- Reduces oil temperatures for better engine cooling
- Increases engine oil capacity
- Reduces engine wear
- Optimizes fuel economy as oil is always clean and friction is constantly in check.
Sturdy Design
AMSOIL EaBP By-Pass Elements are designed with durability in mind.
- Heavy gauge filter housing
- Rust resistant base plates
- Nitrile gaskets
- Silicone anti-drain-back valves
- Dual-stage cellulose/synthetic filter media
By-Pass Oil Filter Element Change Interval
The AMSOIL EaBP should be changed at every second full-flow oil filter change or a maximum of 60,000 miles (96,000 km) when using an AMSOIL Ea Oil Filter or Donaldson Endurance Oil Filter. When extending oil change intervals, using oil analysis is strongly recommended.
By-Pass System Increases Engine Oil Capacity
Between the by-pass filter element and the hoses employed by the system, the engine oil capacity is increased by a significant margin. More oil in the system means less strain on every quart. This extra capacity also results in cooler oil temperatures and longer oil life.
The Ultimate Oil Filter
While regular full-flow filters struggle to grab contaminants at 10 to15 microns, AMSOIL EaBP By-Pass filters are removing soot and dirt at a micron. Soot removal is especially important for diesel applications.
Can AMSOIL By-Pass Oil Filters Be Used With Other Brands of Motor Oil?
All AMSOIL By-Pass Oil Filter systems can be used with any brand of conventional, semi-synthetic or synthetic motor oil.
