Amsoil Air Filter

[GCecchetto]

Anybody using the Amsoil air filter had any problems? Anyone know if Dodge/Cummins has any heart ache with them. I know they don't like K&N's for obvious reasons. I believe the Amsoil is a better filter than the stock unit but I want to make sure they don't have issues with it.

I am using one with no problems so far

I have used them on every vehicle I have owned since 1989, and I still have the 89', and the filter is still in it (160,00) The car is a Dodge shadow/ES Turbo. I also used them in my three CTD's and have never had any problems. My current 03' now has 35,000 plus, and I cleaned and re-oiled the filter about 12,000 miles ago. no problems at all!

I was a little disapointed to see in another thread that the Amsoil air filter seems to not live up to Amsoil' claims. It seems like this always happens to me after I buy something. I guess I need to an AFE now, it seems to be the best compremise. It also seems like the filtering efficiency of the Amsoil filter does not meet the cummins min spec, if I'm reading things correctly.

Gino,

I would like you to SHOW me where the Cummins spec is!

Gino - I changed my Amsoil filter last week after about 12,000 miles and I was very pleased to see no "crud" buildup on the turbo side of he filter box like I had with the K&N and the stock filter. It looked as clean as when I last changed the filter. I bought two of the Amsoil filters and keep one oiled up and ready to go. I do get some high EGT when I pull my trailer but it is managable. Regards, Lynn

Airaid drop-in

GCecchetto,



Before you spend the big bucks on an intake system, go to the Airaid site: www.airaidsales.com. Read a little about the performance filters. Then go find a shop that sells both K&N and Airaid. Look for their comparison demo display. If they don't have one, take both filters out of the box and look at the construction and feel the weight of the things. Then hold them both up to a light. See the difference! Don't know much about Amsoil, but I'm really sold on Airaid!

Don't get all hot and bothered, I use Amsoil lubricants in all my vehicles. I have had problems with Amsoil oil filters in some vehicles though. I can give you details if you like. As far as the air filiter goes, there is a thread on the TDR that my buddy emailed me a link to. The email is on my home computer so I can't go back to that right now. I was looking myself so I could cut and past the info for you but could'nt find it. Anyway it's part of a filter test that gives the filtering efficiency of the filters and it makes reference to the minimum Cummins spec for filtration. You notice in my email I said "it seems" or "it appears" not it "dose not" meet. I have searched on the internet though and found multiple tests including the Amsoil filter and they just don't seem to stack up to what Amsoil says. Like I say, I think Amsoil makes a great oil. I'm not sure that all of their products are of the same quality.

Gino,

I'm not Hot and bothered at all! I have never seen anything regarding Cummins specs. on airfilters, that's all. I would still like to see them.

Wayne;



I'm still looking, trying to find where I saw the reference. It wasn't in the thread my buddy sent me either. I was looking all over the internet for filter tests one night and found a test that was giving the percentage of particulate the filter removed. On one of the filters it gave the percentage and then said "min Cummins spec". I thought it was in a thread on the TDR but I could be wrong since I was all over the net searching for info. I sure would like to see the Amsoil test. Is that available?



Gino

It's either on the Amsoil website or look on the AFE website. It's at either one or the other. If you look at the AFE site, look specifically for the PG7 stuff as I believe the specs are there.

Thanks mberry

Gino,

The last I heard, the Amsoil testing was conducted by using SAE Test Method J726. This is a series of tests that has been established to cover dry type and oil bath air cleaners used on internal combustion engines and to present a uniform method of determining and reporting air cleaner performance. In those tests, the Amsoil "Oiled Foam" air filters performed very well.

By using these kinds of tests, they are repeatable, and considered acceptable by the Automotive Industry. I still have not seen the Cummins acceptable requirements for air filters.

Living in a super dusty region, I've been very happy with the Amsoil air filters I have used in my last two trucks. I think they filter very well, my intake always passes the "white glove" test. And I think they're easier to clean and reoil than gauze filters.



The greatest downside IMO is they don't flow as well as the standard cone AFE. Better than stock I'm sure but not the highest flowing outright. Given priority I prefer good filtration first, airflow second.

I am disappointed with Amsoil

In Advance - Sorry Amsoilman, but I would want people to reply if I were in the market for a product.



I have had Amsoil air filters on 2 CTD now - IMO:



Too hard to clean, difficult to tell if you have the right amount of oil on them after you clean them, Plugs up easier.



Short Version:

On Previous truck, I had the filter plug after a very short time in dusty atmosphere. I cleaned the filter and developed the opinions stated above - swore never to buy one again, but continued to use it.



This truck - used stock filters until 63K. Never saw filter minder draw down - Replaced at 12k, 34k, 51k, and then to amsoil at 63K. As you can see, I went well over the 10K point on every filter - never saw on filter minder and I checked the filter minder - it does work. Since I installed the amsoil, I saw the filter minder show 30% at about 84k. I pulled the filter to find a layer of oily dirt on the outside of the filter. I scraped it off and put it back in. Seemed OK until I received an oil analysis back showing silicon at which time I went back to a paper filter. THERE IS NO PROOF that the silicon is from poor filtration at this time. I will continue to run the paper filter and sample my oil - time will tell.



Currently I have has one sample taken at about 5K and only 2ppm of silicon (the new oil sample showed 1ppm).



The latest issue of TDR sure hit home with me. Lab test and real world test are 2 different things. I understand that there are standards for everything, but sometimes the standard just establishes a starting point. How much filtration do we need, what size of particles are allowable in what percentage, what airflow is required of engines and with what upgrades? I look at everything as a cost, so from now on I am going to watch my filter minder and milage, keep a spare filter in the truck and only change it when the MPG or Minder indicates.

Where did you mount the dual bypass filter on your truck?



Thanks



Gino

 

[draymorris]

I mounted mine on the engine directly above the engine oil filter mount, similar to what is shown on amsoils website. The problem with this postition is that it is very difficult to intall the hoses on the adapter. If I had it to do over again, I would install it on the frame or behind the front bumper. I think I am about to take my unit off and sell it. I have a slow drip from one of the hoses at the adapter and since I can't get to it without removing the hoses and the adapter, I plan on just going back to a high quality filter in the factory place. I had a realy bad oil analysis result a while back and now I found a knock in my engine yesterday after I posted here. It sound like something in the lower front portion of the engine.



Since the oil analysis does not show a particle count, I don't think I can truly tell if the bypass is helping. Everyone that has one says they do, but compared to what? Now that I am going to have to take my truck in for an engine knock, I am afraid that the dealer will dispute warranty work if they find something oil related went wrong and I have the bypass on there.



At this point, I am not sure if any of these oil related upgrades are worth the stress. My truck has 93k on it, I should not be having to worry about an engine knock!

 

[GCecchetto]

Sorry to hear about the knock in your engine. Are you saying you think the bad oil analysis is related to the knock in your engine or the filter? Did you notice the oil to be less black with the by-pass filter? Hope your engine gets taken care of.

I thought the bad oil might have been, but it looks like I may be wrong. Took it to the dealer yesterday, they said it sounded like and injector. They told me that they were told that 2-cycle oil, instead of the old transmission fluid trick, might free up a sticking injector. They took a quart of 2-cycle oil and added to the fuel tank. It seems to have worked as of this morning. I am going to post about the whole thing when I get the chance.



Regarding the air filter - I had a TAG installed and took it out before I went to the dealer. When I removed it, I notice that there was a dirty film on the leading side. Before I used the Amsoil filter, I know the TAG stayed clean. I am done with the Amsoil air filter! So, I now have a used Amsoil air filter for sale, and a Amsoil Dual by-pass unit.



No, the oil is just as dark with the by-pass unit. The only filter I have heard of that keeps the oil clean is a Pyradyne.
