bypass filter

[Okie-Go]

Was at the trailer factory where I load at the other day and a gentleman gave me a flier on by-pass filters. It was a kleen-oil brand. I had a fs-2500 on a previous truck and took it off and sold it when I traded trucks. Has anyone heard of this brand, the price wasn't bad compared to the one for the fs-2500. Thinkin one for the Freightliner wouldn't be a bad idea. some thoughts would be appreciated. kleenoilusa.com

Is there any good reason to add another filter? I assume that you follow a regular oil and filter change program. Are you on a long extended oil change? Many of the B series Cummins engines live a very long life on the factory single filter with regular oil changes.

I have a mercedes benz engine in the truck I am talking about. I run synthetic, eight gallons. Thought with a by-pass filter I could stretch the changes a bit. Could change the bypass at 10k then another 10k change oil and filters again. Prolly a bit too protective of this engine. Past eight days I ran 5100 miles. Seven days before that ran 4200.

To Protective?

Take a look at the price of a rebuild vs the cost of the filter. I have had an FS 2500 on my truck from DAY ONE. I think that its pretty cheap insurance. Very close to 200k and ABSOLUTELY NO PROBLEMS.

It is true, that many Cummins engines live a long life on single filter and regular oil, but a by-pass filter will significantly improve oil cooling, efficiently increase filtration capacity, remove smaller particles of wear metals and SOOT, as well as extend oil drain intervals do to their ability to operate at a slow rate of flow, and remove the smaller size particles that are generated by the engine operating conditions. In the case of the AMSOIL by-pass filters, they are over 98 percent efficient at removing particles as small as 2 MICRON, and will remove 39 percent of soot contaminants less than 1 MICRON.

It has been proven over time, that most wear occurs from particles 5 to 20 MICRON in size. In my mind, anytime you can get better oil filtration, the better the oil is going to be free of wear causing elements.

One of the drilling contractors I worked with had the Frantz on their Detroits. They said it doubled the oil change interval based on oil testing. The Frantz uses either toilet paper or paper towels in the bigger engines. Personally, I'd prefer a little more scientific approach with a know micron. (Do I use Scott or Charmin, the choices are overwhelming).

The bypass technology is solid however, and polishing the oil with a bypass filter has been around for decades and will extend oil change interval. Only a an oil analysis will determine just how long. I've also seen centrifuges also on larger gas compressor engines. I'm talking an engine the size of a railroad box card. That work very well also. It's true synthetic oil holds it's viscosity etc... much longer but it gets dirty just like any other oil.

I have been running the Oilguard system for at least 10 years. I did not install it for the extended changes but to filter more from the oil. The engine is a sand casting and the same principle of sand leaching into coolant passages I believe holds true for oil also. Some have gone as far as coolant filters and say they are still running the same water pump for quite a few years. Besides I want more than a million miles

Anyone heard of bypass filter starving the turbo of oil?
Someone mentioned it might be a problem if oil pressure drops is lowered after installing bypass system.
I have a 2013. Don't know if anyone has modified a 2013 with the bypass system?

Most bypass oil filters that I am aware of will only flow a very small amount of oil through them. In the case of the "AMSOIL" brand, the flow rate is about 6 Qts. every 5 MINUTES @ 40PSI. Because of the restricted flow, there is no loss of oil pressure.

I had good results running Amsoil BP 90's on a 6 cylinder Isuzu Amigo for 12 years.

BUT it didn't have a turbo. I have actually never had a turbocharged vehicle. I know turbo's require different lube pressures to keep everything lubed and the turbo is sensitive to lack of oil and not in the main oil flow as the oil is pumped to the rockers.

But I'm planning on going with the larger capacity Amsoil BP 100 on my CTD. In fact, I've already bought it. Just haven't yet installed it.

What you say Amsoilman makes perfect sense. Just beong cautious and trying to gather info before making the jump

Actually, the flow of oil from the oil pump flows to the "FULL-FLOW" Filter and from the full flow filter directly to the turbo for lubrication, as well as cooling. If a bypass filter is connected properly, the "bypass filter" and the "Full-Flow" filter are connected in "Parallel" with one-another, and with the restriction in the outlet of the by-pass filter the larger volume of oil will flow through the Full-Flow" filter, as it is not restricted.

I don't have the Amsoil bypass filter unit, but another brand and use the Amsoil eabp100 filter. From what information I had, the units restriction reduces the flow where it allows the filter to clean more efficiently. About 10% or less of the total output. And from the oil samples I've had, it does a great job. I also recommend the Donaldson ELF filter as your main filter. Most filters for our trucks filter down to 35 to 40 microns. The ELF is rated at 17. With the Amsoil by-pass filter rated at 2 micron, your about as protected as you'll ever be. Just keep up with proper filter change out. I just started a long term run on the oil and hope to get as long a possible.

Also, when I installed my unit, I removed a small plug on top of the stock filter head and ran the bypass filter supply line from there. The outlet goes back to the valve cover so your never left without oil levels or sufficient flow ever. This idea has been around for decades. When I came back from Vietnam, I drove truck for a couple of years and there was a bypass unit on the Mack, that was factory install as a standard unit. The manufactures have removed them because the filters and oils improved over time and they could save money making their trucks with less parts weight and cost.

Talk to people who have them and if they have sent in oil samples, listen to them praise the units. Best bang for the buck.
