Healthy Diesel after ByPass

Many diesel owners' questions and concerns about the new Ultra Low Sulfur Diesel Fuel (ULSF), EGR & # 39; It's DPF's. s, and larger diesel engines have been paying attention to the growing need for additional refinement in our diesel trucks. This article should take a bit of the mystery of Bypass Filtration.

A man was once told by his wife and doctors to take white pills daily. She didn't like spending time & money taking these pills, but eventually, she started using her routine. Years later during the examination, the doctor told her that she had a mild heart attack, but thanks to the blood-thinning aspirin she took daily, her life was saved. The doctor expected her to live for many years while taking aspirin and watching her diet. Like aspirin, bypass filters can extend the life of the engine and protect it from wear and tear. The cost for the Bypass system is minimal compared to the benefits it receives.

Why use Bypass oil refining?

Wear is a constant threat to engine performance and life. Wear due to having dirt particles suspended in oil larger than oil film between moving parts when equipment is under load. The current full-flow oil filter lasts about 50 gallons per minute and removes particulates (incomplete combustion products) in 25 microns and larger ranges. That may sound reasonable, but studies have shown that the most harmful particles on your engine are in the 5-20 micron range. ByPass filtration is perfect for removing soot particles of 1 micron and smaller.

This year diesel engine manufacturers have increased the EGR (cooling off of gas exhaust) from 15% to 30%. EGR engines run hotter and have less efficient combustion. The new truck engine will be subject to higher levels of soot & acid being thrown into the engine, increasing wear, oil viscosity and shortening the drain hose as oils and filters deal with more pollutants.

Older diesel trucks also require bypass filtering protection. With time, these engines tend to allow compressed gas to explode into the crankcase. This gas carries carbon from incomplete combustion, produced by the filter. Oil filters must filter out more and more carbon as they are formed in the oil. The longer the engine gets, the more carbon must be emitted. Higher mileage diesel requires additional shortcut protection such as newer engines.

Full flow filters do not eliminate the small leakage of cooling or condensation created by the engine, but bypass filtering can capture and evaporate these foreign fluids before problems become severe and reduce the risk of oil damage, engine rust and corrosion. Regular filter changes and oil analysis should sometimes detect (not mask) any engine problems.

The Bypass system helps by adding another 2-3 liters to the amount of oil circulating through the engine allowing for additional engine cooling. Cleaner oils reduce the thickness and minimize the formation of sludge and other deposits on the engine parts. Not only is Bypass filtration important, but it should be used in conjunction with high quality synthetic oils that provide oxidation inhibitors, detergents and dispersants in their basic stock.

What are the benefits of Bypass?

  • Extremely Extended Oil Drainage Meetings, in some cases> 100,000 miles
  • Oil Improvement Improvement
  • Fuel economy improved by 5%
  • Small particle breakdown and Soot removal
  • Improved Advanced Engine Life, Often Overrides
  • Rust Reduces Rash & Corrosion
  • Ongoing Equipment on Clean Oil
  • Improvement in Engine Efficiency
  • Less Downtime
  • Remove Particles Less Than One Micron
  • Less Oil Disposal & Less Oil in the Environment
How does Bypass filter work?

The bypass system has been around since the 60's. s. Bypass filtration is a secondary oil filtration system that passes through an existing oil filter, extracts oil from the oil delivery unit or adds an oil pressure port, to the remote filter, and then returns the oil back to the engine via oil cover or valve cover. Some owners may notice a slight decrease in oil pressure, but system manufacturers have noted that up to a 10% reduction in pressure can be ignored. The Bypass system is called a "partial flow" which means oil is filtered at 8-10 gallons / hour, instead of a full 50 gallon / minute flow. The oil is now dried to less than 1 micron and you have removed the engine almost.

There is a Dual Bypass filtration system (two remote Bypass filters) for 15 liters & larger sump oils.

There is another type of filter that combines full and partial flow called "Dual Remote". This system takes the place of the full flow filter and replaces it with two filters remotely similar to Bypass.

The bypass system is fast and easy to install. A mechanical minded person can do it in an hour or two.

Who built the Bypass system and how much did it cost?

There are several players in the Bypass market: AMSOIL, Fitrah Solutions, and OilGuard to name a few. AMSOIL offers BMK-11 (Bypass Installation Kit), Refining Solution has FS-2500, and OilGuard with EPS-20.

The Amsoil BMK-11 runs around $ 175.00- $ 200.00 for kit installation and installation. A diesel truck can expect to pay an extra $ 50 (Dodge) $ 100.00 (GM) & $ 150.00 (Ford) for special equipment. Special EaBP filters are around $ 35.00- $ 45.00. You can pay $ 10.00 to become a Preferred Customer with AMSOIL and save about $ 50.00. The AMSOIL EaBP filter should be replaced after 25,000 miles or 1 year, whichever is earlier.

The FS-2500 Filtration solution runs around $ 400.00 (depending on your vehicle) for the complete kit, including filters. The additional filters cost about $ 22.00 each and need to be replaced after 10,000 miles.

The OilGuard EPS-20 for a diesel truck will cost $ 229.00, but the installation kit will add $ 100.00 (Dodge), $ 160.00 (GM), and $ 257.00 (Ford 6.0L). An additional filter of only 8.00 each and under normal highway driving shall allow 4 times the manufacturer to drain the hose.

Arguments continue to be the best. The tests prove that the system is efficient. The normal rewards for this system are approximately 70,000-100,000 miles. If you want the kit installed, you can go to the fashion store and pay anywhere from $ 50- $ 125.00 for installation.


Bypass oil refining systems only provide the ultimate protection for your old or new diesel engine. Testing shows the system can drastically reduce maintenance costs over the life of the vehicle and extend the life of the engine. The combination of these two filters is synergistic in minimizing engine wear and corrosion. The only drawback is the possibility of reading lower oil pressure and more points for oil leaks.

If you only drive your truck a year before trading, this system may not be for you. but if you really care about the investment you make in your truck, then this investment is most beneficial and worth the price. If nothing else, they make filters periodically change the wind.

Get Bypass and save yourself a heart attack when you see a budget for a rebuild diesel engine.
