EAO34 Oil filter sold by AMSOIL

oldnavy · **Posted:** Sun Mar 18, 2007 10:57 am

I am posting a link here to the VW TDI Club forum where Georgeseq has posted testing data on the new filter. The testing was done on a Toyota gasser he owns, but it will apply to a diesel in same way. In the gasser the used oil was cleaner 1550 mile test period then when installed new off the shelf. The testing was done by George Morrison, STLE CLS of AVLubricants ( AVLubrication ) who is consider on of the top lubrication engineers in the country. I know we have at least one member here using the EAO 34 filter on their CRD, and I look forward to hearing the test results if this person send off a oil sample to be teste. Hint, hint!!!

I was going to try the filter this week when I do the oil change on the wife's CRD but forgot to order the filter till today, so I will wait till it gets here and not use the OEM filter. I guess I had another senior moment when it came to the oil filter, bought the oil last month. Talk about half stupid prep. :roll:

I may put this info in the CRD FAQ later if this filter proves a big bonus to cleaning up our soot ladened oil, but for now it will be just an Announcement so everyone can keep up with this topic.

If this filter proves out, and add in the EGR Off Road Mod (no soot getting recirced into engine), you're talking 10K oil changes easy.

Looks like this beast might be a keeper after all.

The only thing is the filter is listed as the same for the 3.7L gas, so I am hoping to hear from those here using th filter to see how it is doing. I am needing to change the oil this week and will have to either make the leap or go wit OEM filter. Decisions decisions. :roll:

I have used the Amsoil Eao34 filter on my CRD since the first oil change. It has worked well. Haven't sent in an oil sample.

Yep, the same filter is listed for the gasser. Good to read about the test that was done.

I will continue to use it.

How many miles have you been using the filter?

My problem is they list the same filter for CRD & 3.7L and they do not take same filter. The OEM filters for the two engines are different size and and appear to be different internally when you look at them, the real difference is most likely only the by-pass valve pressure. However that could be a big problem if it dumps/by-passes the filter way too soon due to all our soot/carbon that a gasser does not have in their oil. You should have a oil sample tested just to make sure it is not doing that if possible.

I've been running the Ea034 since 5k. I've had, I think, 3 oil analysis performed on this filter running Amsoil's 5w-40 European Formula oil.

Runinng 10k with this filter and either the Amsoil 5w-40 or Mobil1 Truck Turbo Diesel 5w-40 (formerly Truck & SUV) is not a problem EXCEPT that my silicon levels get to be abnormal above the 5k range (I'm probably sounding like a broken record on this :lol:

) Either the OEM air intake system (probably the culprit) is contaminating the oil with relatively high amounts of silicon, or something internal (like a gasket) is throwing off silicon. If my high silicon level is due to an internal gasket or something like that, then no big deal; if it's air intake related, it's a bigger deal.

I'm not extending my oil change interval to 10k unless I can determine the cause of the silicone contamination.

I'm wondering if the EGR ORM will help matters in this regard, including the silicon.

Yesterday I did a dump and flush on the engine oil. After draining the old oil, I put in 6 quarts of leftover Rotella 15W40 and a Fram oil filter, ran it for 10 miles and then dumped that, then put in Rotella 5W40 and a good filter on it.

Last night, after doing a 10 mile run to dump off the old oil at Advance, I pulled the dipstick to check. It still looked like new oil, with only a hint of black tinting.

That's a definite improvement over the last couple oil changes, where it turned black again as soon as I ran the engine to refill the filter and system.

We'll see how it checks out in 3000 miles, and how long it takes to turn black again, now that the soot ingestion system is turned off.

The lack of EGR will reduce a soot level greatly, but will not eliminate all soot in the oil thanks to normal blow-by of a diesel engine. Now with the help of ULSD, no EGR, no CCV and a super filter, we may have oil that looks almost like the gassers oil.

What is the EGR ORM?

Nevermind...I just read an earlier post :roll:

I don't see where silicone levels would be affected either by having an EGR installed or not.

Soot has been at manageble levels per my oil analysis, even at 10k. TBN's were OK at 10k, but with the Amsoil Oil I wouldn't stretch it too much farther (Amsoil starts with a TBN of around "8").

I think (at least in my situation) our limiting factor in stretching our OCI will be the OEM air intake system.

Anybody else have oil analysis that can either back me up or refute my claim?

oldnavy · **Posted:** Mon Mar 19, 2007 1:13 pm

My one oil sample was high in Si and the trouble was the airbox not sealing proper and it had broken. It was changed out under warranty and then replaced later with a '02 3.7L airbox so I hope this oil sample shows a big drop in the Si for a 7,000 mile oil change.

I'm sending my 7K oil sample in this week. This sample is Mobile 1 Diesel CI4 oil, OEM filter and egr on for 99.9% of the mileage. Will know something soon. What was your soot and silicon level? Did you already post your UOA here?

Thanks

No, I didn't, at least not completely. Here they are:

5,200 miles on oil (soot) 1.60 (silicon) 18
10,200 miles on oil (soot) 2.18 (silicon) 33 Air filter changed at 5,200 on oil.
7,461 miles on oil (soot) 2.21 (silicon) 45
4,923 miles on oil (soot) 2.06 (silicon) 27
6,376 miles on oil (soot) 2.30 (silicon) 35

In each example, I started with fresh oil, oil filter (Ea034) and air filter. In the second example I changed the air filter at 5,200 miles, but ran the oil and oil filter for a total of 10,200 miles. In the next example oil & filters were run for 7,461 miles and silicon is higher.

Oil Analyzers did the analysis in all cases and they report silicon as "abnormal" when it goes above 30.

Interesting data. If memory serves me correctly, some of the CRD UOA's that were posted a while back show a somewhat high silicon reading. Looking forward to seeing your next UOA soot level, assuming you done the ORM. I'm more than a little curious about the high si readings from more than one source. I've cleaned and reseated my airfilter contact area several times this past oci - hoping that will bring in a decent si reading.

PS - what did the insolubles reading show?

I have not done the ORM; everything is in stock configuration. Personally, I don't think the ORM will affect silicon readings and that's what I am most concerned about. My silicon levels are managable when I change oil somewhere between 5k and 6k, and change my air filter every 5k.

My "opinion" is that our CRD's need better air filtration; the stock set up does not / cannot properly filter air much past 5,000 miles.

By "insolubles" I assume you're talking about solids. Oil analyzers reports one number for soot/solids; those are the soot numbers I reported earlier.

Thanks for the update.

Back to the Amsoil filter. I emailed Amsoil asking about the same oil filter fitting both the V6 and 4 cylinder diesel. They responded back that WIX and Purolator both show the oil filter thread size as 3/4 X 16 on both engines. That's the first standard size I've seen listed on the CRD engine.

I replied and asked them about Jeep/DC and Mobile-1 specifying different oil filters, as well as asking the bypass relief pressure on the EaO34.

The operating oil pressure specifications are different for the 2 engines.

Oil Pressure ratings from the FSM(s)

2002 3.7L V6 gasolene engine
idle - 650 rpm - 4 psi minimum
3000 rpm 25 psi - 110 psi (quite a range)

(Real world on my V6 Liberty - at 60 mph ~2000 rpm, my V6 reads 98-100 psi consistently, at idle, warmed up, 28 psi using Mobile 1 5W-30 synthetic)

2005 2.8L 4 cylinder diesel engine
idle - 760 rpm - 10 psi minimum
3800 rpm - 29 psi

Can't read actual oil pressure on my CRD with my obd software

So, if the EaO34 works for the V6 engine, do they bypass at 115 psi? If so, how would they bypass for the R428 assuming it runs around 30 PSI. Maybe someone who can read the actual oil pressure on their CRD can chime in with some information.

I could see the ORM increasing silicon levels due to increased volume of fresh air coming through the intake.

Please post your oil analysis numbers here so we can see them in one place

I checked the Purolator website, as they also list different filters for the V6 and CRD.

On the specs page for both filters, they listed the bypass relief setting - 12 to 15 psi for both the V6 and CRD filters.

Checking the Wix website, the 51516 filter they list as fitting both the V6 and the CRD has a bypass setting of 8 to 11 psi.

I think they're actually talking about differential pressure across the filter, not oil system pressure. Otherwise, from what you posted for the V6, the oil filter would be operating in bypass 100% of the time, even at idle with a new filter.

Thanks Mitch... differential pressure. Now it makes sense. So it sounds like the amsoil should work, right? Still wonder why DC and Mobile 1 use different part numbers.

You guys need to do something different with your air filtration. The silcon numbers are unexceptable IMHO. As for TBN it all depends on which Amsoil oil you are using. TBN limits are 3 on the bottom side and the diesel oils start out at 12 TBN. I would like to see what the rest of the report said for wear metals. Yes the releif pressure is DP.
