What Bypass Oil filters are available?

[Archive]

I have been considering a bypass oil filter, but have only heard information on the AMSOIL filter, but some users have listed other filters on their signatures.

I haven't heard anything negative about the AMSOIL, but the only information that I have seen available is from AMSOIL.

Later,
Tim

I've been an Amsoil user for some time but I'm not an Amsoil fanatic. I believe it's as good as any oil out there. On the other hand there are a LOT of good oils out there. I just think it's a little silly to argue which is the "best" oil because I doubt any engine can distinguish between the better grade oils.
Having said that, I run an Amsoil by pass filter. It's probably as good as any out there. Other filters? I know of two: the first (PURADYN) is being discussed simultaneously with this thread in the 24v forum. If you haven't already, you might want to jump over there and take a look. The Puradyn has an electric grid in it to boil off moisture. An unneeded expense, if you ask me. Why? Because the elements in most bypass filters are made of cellulose which absorbs water. There's no need to boil it off. Also, introducing "additives" to the oil, which the Puradyn does, is a dated concept of little value. You buy the right oil and the additives are there and will last.
The second bypass filter I know about is a brand called HARVARD and it's very similar in design to the Amsoil, except, after reading the literature, I think it may be better. It looks like it's better made and I think the element is a little more substantial than Amsoil's. Price is about the same. Do I intend to use one? Yes, because I don't believe Amsoil has a monopoly on quality. By the way Amsoil doesn't "make" any filters; they're made by others to their specifications. Also, the Amsoil remote filter mount(or ANY remote filter mount) can be had with a inexpensive petcock so you can obtain oil samples for oil analysis. There seems to be some confusion about that.
If you want more info on the Harvard, just post a response and I WILL get back to you.
Take Care,
Duffy

EZ94,
I read your post concerning the Amsoil by-pass oil filters. I can assure you with all certainty, the by-pass oil filter elements are manufactured by Amsoil Inc. They do contract out the others.

Thanks for the correction. Over the last several months it's been a pleasure reading your input on oil realted issues. More than anyone else you continue to provide everyone with a wealth of information on every oil realted discussion I've seen. Personally, I can't thank you enough for all of the time you spend doing so. It's been an enormous benefit for me.
As you know, I am an Amsoil user, but I'm not emotional about it. Seems as though discussions about oil have a habit of becoming very emotional very quickly.
What I find interesting about this thread is that it's generated so little interest. No matter what oil one prefers, taking better care of the engines in our trucks should generate some response time.
By the way, if you've heard anything negative about the Harvard filter, please let me know. I would be happy to listen to your comments.

Thanks,
Duffy aka EZ94

I just spent an hour at Puradyn's website. Pretty dang comprehensive/impressive. I agree with you, I think a bypass filter far outways the differing benifits any oil, synthetic or mineral can provide given your within specs. One glaring advantage I saw was Puradyn's ability to filter down to 1 micron, I think the best amsoil does is 5 microns, and according to some it doesn't matter if your at 5 or 15 microns, real benifits in engine wear don't show up until your well below 5 microns. thats my two cents worth, go check out info@puradyn.com and if anybody has cost/avail. /info on the other 2(Harvard&???) I'm interested #ad

EZ94, I would be interested to learn more about the Harvard bypass system. Please enlighten me. Thanks in advance. John

Tomcat,
I recently put this info on the web, but I will do it again, as you may have not seen it. It was an article I read in an oil Filter publication.

Here is the article:

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.

I'm here to tell you the Amsoil brand "by-pass" oil filter achieves high efficiency. For particles of 3 Microns and greater, they are 98. 6 %! At 1 Micron, they are 71. 2 %! Their "Full flow" oil filter achieves high efficiency for particles of 20 Microns and greater. In fact, its efficiency for 10-Micron particles is 65 percent and its efficiency for 20-Micron particles is 98 percent! The tests I am referring to is the SAE J806 and SAE J1858. Together, the "By-pass" and the "full-flow" filters offer significantly greater protection than that of a conventional filter system.

EZ94,
Thanks fo the Kudo's! I do try to read as much as I possibly can concerning oils and lubricants as they are, afterall, the life blood of our engines!

I have not heard anything negative of the Harvard filter, except the price.

Anything that will filter out particles less than 20 microns, will most certainly help any engine! Unfortionatly, a common "full flow" filter just does not do it! The filtering media can not be very dense, as it will then obstruct the flow. This is why a by-pass filter is connected into the oil system in parallell with the full-flow filter, sending by-passed oil to the by-pass element from the main system.

Thanks again,


Wayne
