which oil filters offer 30ppm

[CATCRACKER]

i have heard that oil filters which screen 30ppm vs 40ppm increase the life of an engine up to 50%. is this the case. what ppm are the napa gold, fleetguards, dodge's filters... ... anyone?

I think the terminology you are asking is MICRON, refering to how small of particles the filter will catch or let pass... ... ... ... If that is the question I can say that the Fleetgaurd filter will filter down to 10 micron so anything less that 10 micron it will let it pass thru, I have like many others installed what they call a by-pass filter, I dont like that terminology but I prefer to call it a slip stream filter, the OEM filter filters 100% of the oil flow thru its filter and the slipstream pulls a 10% slip from it and filters it down to 2 micron, this works well and helps to keep your oil clean alot longer. Remember this oil does not wear out it just gets dirty or contaminated with other fluids so if you filter it better you help maintain the life of the oil! thus helping the life of the all mighty CUMMINS

The reason it's called a by-pass filter is because the oil that passes though it by-passes the normal lube path of the engine and goes straight to the pan.

... in the case of the single remote mount. For the Amsoil dual remote mount, all the oil goes through the engine lube path.

Perhaps it might be more correct to say that it is called a bypass filter because a small amount of oil bypasses the full-flow filter to be run through the other filter.

I've talked to Fleetguard about the Stratapore and think they said about 73% @ 10 mic. and absolute at 30.

 

[Whitmore]

Actually the single remote mount gets its feed from the discharge of the oem 10 micron filter , but you are right the filtered oil from the 2 micron remote mount doesnot supply the Cummins , instead it is returned to the pan or the oil fill cap and then to the pan or sump to start all over again.

We use this 10% slip stream setup at work and it is magic for the motor

[CATCRACKER]

how much is the 10% slip stream method cost$?

 

[Vaughn MacKenzie]

I heard the Stratapore filters down to 15-20ppm, if I remember correctly.



The Microglass filters go down to 10 microns, but since they filter so fine, they don't last very long.

Vaughn:



You got it backwards



The Stratapore is the better filter.

 

[Vaughn MacKenzie]

Well after a lot of digging:



Stratapore: 100% efficient @ 30 microns, 60% @ 10 microns

Microglass: 100% efficient @ 30 microns, 70% @ 10 microns



So they are pretty close in filtering efficiency, slight edge to Microglass, but the Stratapore holds "a lot more dirt" and has a stronger case to withstand higher pressures (and maybe stronger media too, just a guess).



I could have swore there was a big long discussion about oil filters at least 2-1/2 years ago and Fleetguard gave the filtering efficiency specs on the two filters and the Microglass filtered to a smaller micron size than the Stratapore, but maybe my memory is faulty



Vaughn

 

[GLASMITHS]

Microglass better?

I'm glad you posted those figures. It's just been my impression from all the posts that the Stratapore was the better filter. It costs more anyway. Maybe the most expensive is not the best way. :{

It's like everything else. How much you got? (we can extract it from your pocket)



First, I recommend either the Oilguard unit or the Amsoil SINGLE remote, even though I have the DOUBLE. There's pros and cons; I'm not going to repeat them all here but you can find them on old posts if you are interested or talk to Amsoilman on the phone.



The basic units run somewhere in the $125 to $150 ballpark; if you want to get a pre-fabricated battery mount you might spend another $50 (?) by the time you add shipping, etc.



Costs can be kept lower by getting a Fleetguard bypass filter (LF-777 if I recall) and buying the Fleetguard mounting head, BUT if you go that route you need to figure a way to get a smaller oriface installed in the line. The "standard" oriface with that line is about twice the size that is appropriate for our smaller engines and would pass more than 10% of the flow to the bypass filter; possibly starving the main flow path a bit. (Unacceptable. ) By the time you find the hoses, fittings, etc, you may have invested more time than what it is worth to you; there's a lot to be said for buying a "kit" where someone else has already figured it all out for you (Oilguard, Amsoil, etc. )

As Vaughn already alluded to, even though the microglass has a little higher single pass efficiency (which I too thought was the other way around), the Stratopore has a larger holding capacity.



Here is an interesting read regarding the Stratopore media:

Found this very interesting and believable - "metallic partials smaller than the filter rating passing though the filter will cut the passages thereby enlarging them. " I've always been very skeptical of magnets and their claims but was a sucker and ordered one. Good read anyways with real data http://www.thebeartrap.com/information.htm

The latest edition of Diesel Progress has an article titled <b>Advances in Magnetic Oil Filtration</b>. It features One Eye Industries in Cagalry, AB that produces the Beartrap and others.



Vaughn and others. Kinda funny that a Stratapore filter with slightly less performance than a Microglas is the <em>better</em> filter. I've got the data (someplace) that describes why this is better. If memory serves, it has to deal with multi-pass efficiency and extended drain performance.

Catcracker,



I recently read an interesting article on Engine oil filtration, you might be interested in, so here it is.



According to the (SAE) Society Of Automotive Engineers paper 881825, AC Spark Plug and Detroit Diesel Corp. performed a joint study of the relationship between the level of engine oil filtration and Engine wear rates, and found finer filtration reduced the rate of Engine wear.



Diesel and Gasoline Engine wear rates were established by building a Diesel and Gasoline Engine with fully inspected wear components and inspecting them after the test. In both Engines, the upper and lower main bearings, oil rings and compression rings were inspected. In the Diesel Engine, the cam lobe profile and cylinders were also inspected, while the piston pin bushings, piston pins and cylinder liners of the Gasoline engine were inspected.



The total test duration was eight hours. To accelerate wear, 50 grams of AC Fine Test Dust was added, in slurry form, to the crank case every hour.



Diesel Engine wear tests were performed using filters with high efficiency ratings for particle sizes: 40 Microns, 8. 5 Microns and 7 Microns.



Gasoline Engines wear tests were performed using filters with high efficiency ratings for particle sizes of the following sizes: 40 Microns, 30 Microns and 15 Microns.



ANALYSIS



The researchers found clearances in the Diesel and Gasoline Engines varied between 2 and 22 Microns during engine operations. That means particles in the 2 to 22 Micron size range are most likely to damage Engine parts. Particles smaller than 2 Microns will slip through the clearances without damaging bearing surfaces.



CONLUSIONS



The researchers drew the following conclusions:



Abrasive Engine wear can be substantially reduced with an increase in single pass efficiency. Compared to a 40-Micron filter, Engine wear was reduced by 50 percent with 30-Micron filtration. Likewise, wear was reduced by 70 percent with 15-Micron filtration.



Controlling the abrasive contaminants in the range of 2 to 22 Microns in the lube oil is necessary for controlling Engine wear, and “The Micron rating of a filter as established in a single pass efficiency type test, does an excellent job indicating the filter’s ability to remove abrasive particles in the Engine lube oil system.



The smallest particles most popular “full Flow” filters capture with high efficiency are sized 25 to 40 Microns, depending on the filter brand.



BYPASS FILTRATION



You might look at a by-pass filter as an addition to your engine’s security system. Your regular oil filter passes the full flow of oil from the pump and removes particles bigger than about 20 to 30 microns. Left in the oil, particles smaller than this size can contribute to ring, liner and bearing wear. These same particles can also contribute to engine deposits, which can hurt engine performance and induce oil consumption.



If the regular “full-flow” filter were designed to filter smaller particles, there would be a risk of insufficient oil flow through the engine as particles accumulated in the filtering media of the full-flow filter element. In fact, regular filters come equipped with a “relief” valve, to allow some of the oil to by-pass them completely. These valves insure the proper flow of oil is maintained to protect the engine, even if the filter media accumulates enough material to cause excessive pressure drop across the filter, or the oil is too thick to pass through it fast enough.



By-pass filters are an addition to the regular oil filter. They take only a portion of the oil pump’s flow, and can therefore be more efficient in removing even smaller particles than 5 microns. Eventually, all of the oil gets circulated through the by-pass element. Removing particles smaller than 20 microns is another step in reducing the risk of engine wear, and can also help in reducing risk of oil viscosity increase.



A side benefit of a by-pass filter is that it usually increases the amount of oil necessary to fill the engine oil system. More oil means contaminants are less concentrated and likely to cause harm to the engine. More oil also means more additives are available to neutralize contaminants and protect vital engine parts.



By-pass oil filters can add to your line of defense against engine wear and deposits, helping maintain engine performance and long engine life. When it comes to providing you with security for your engine, a high quality filtering system goes along way.



Hope this helps,



Wayne
