IMPORTANT FOR AMSOIL AND AMSOIL FILTER USERS 6.4L

[JS4024]

So I do not sell amsoil but I do use it religously. I have been using the SS 0W-40 and an EAO17 filter. The site used to recommend the EA15K50 Amsoil filter which can be crossed up to the EAO17. The EAO17 is about 1 1/2 inches bigger than the stock filter and the EA15K50. Now they only show a cheap WIX filter on the site for the 6.4L engine. Why one might ask?

They found that some users of their SS 0W-40 and the EA15K50 are throwing an oil pressure check engine code. They believe they made the filter too good and it is plugging up with all those 20 micron particles.
Their answer is to use this cheap WIX filter instead because it doesn't filter as well.

I have been using the EAO17 filter without issue however amsoil who initially suggested that to me, backed off and said only use the WIX filter.... Just beware, amsoil said the filter will bypass after as little as 1,000 miles!!! NOT GOOD!!!

Which filter will bypass? The loaded up Amsoil EA017 or the Wix, which I thought was one of the better made filters on the market???

The filter with the "issue" per Amsoil is the EA15K50 which was the recommended filter for the 6.4L engine. I didn't like the fact that it was not the 25k filter but only the 15k filter so I called Amsoil tech support and they said that the EAO17 is the same fitment but it is a longer filter. The tech said you will actually have a lot more filter media. As I stated that is the filter (I use). However if you had gone to the Amsoil website they would have steered you to the EA15K50 which is the filter that seems to be causing the issues. Apparently being a 20 micron rated filter it is filling up with contaminants too quickly and then going to bypass. I did call the WIX filter "cheap" but it is a 7.00 filter and it is NOT the XP version but simply their run of the mill filter. Did not mean any dis on WIX. My issue is... you get no extended protection. Why pay for oil that will last for 25,000 miles when the filter doesn't. BTW, I religiously change my oil when the oil minder goes off... I just like having the best protection available and if I go over because I am in the middle of a trip I have no worries.

I just checked the Amsoil Website and they claim ALL their Oil Filters have a 20 micron rating. The WixXP I used is a 35 micron filter. I saw some Videos on you tube of filters being taken apart and the WixXP was by far the best made they checked. (Amsoil was not in the batch). I personally don't have a problem with 35 microns of filtration... Spending twenty bucks for a filter that may clog up real soon doesn't sound so good. Thanks for the clarification.

Huh? Didn't Champ Labs make the filter for Amsoil & Royal Purple? Why would a "code" be thrown if the media went into bypass?

The solution isn't to not make a filter - the solution is to make a filter with enough media surface area to hold a normal OCI's worth of contamination. See the Oil Filter thread.

I didn't get the Check engine code clearly from the Amsoil tech support guy. I think he said it had to do with low oil pressure and the MDS system functionality. A clogging filter will lower your oil pressure. Probably when it gets to the point of MDS not working, it is pretty much in bypass.... ????

Bypass means it's unfiltered, flowing freely.

I have been using Amsoil SS 0-40 and the EA15k50 and had no issues. Currently have 74,000 and change it around 6000 miles. Depends on the oil percentage and if I have a road trip planned.

Doesn't Fram Ultra Synethic have the same micron rating?

What is the dirt holding stat for the Amsoil Filter?

The Purolator Boss is 27 grams, for example.

To be honest I have always used the signature series oils and the 25k mile filter. Amsoil does one thing, oils, and automotive fluids. Their filters are typically rated on U toob to be extremely well built and high quality. I think the micron rating is 98.6 at 20 microns. The issue I think they are running into is that the EA15K50 filters media is filling up with the 20> particulates which then cause oil pressure issues?? It may turn out to be a bad MDS solenoid in some of the 6.4L engines but Amsoil pulled that filter for the 6.4L engine and listed the WIX filter instead.

Bought a case of the filters last month so I guess I will see what happens.

It's good they did that.

I don't think we will figure it out.

But, the answer doesn't feel right to me.

If the filter fills up then the bypass valve should open, avoiding any codes.

And how dirty would the engine have to be to fill up the filter?

Fram is paper garbage.

If the Amsoil lacks dirt capacity, don't use it. There isn't a pile of difference in a 35 micron filter and a 20 micron filter. I assume these rating are both Beta 1000? If the test procedures are not specified, the numbers are meaningless. I deal with hydraulic system bid specs. If they don't specify Beta ratios in the bid specs, anyone can meet any spec. my sock will stop some % of 2 micron particles, so I can claim its a 2 micron filter, can't I?

engines last longer than the rest of the vehicle these days, so just follow OEM recommendations and you'll be fine.

 

[HEMIMANN]

Fram Ultra Synthetic advertises 99% filtration @ 20 microns. Some time ago, their flow restriction was low as well. I can't find it on Fram website, so maybe it's old info. Or was on BITOG.

Anyway, Fram Ultra is worth the couple extra bucks IMO. Generally more surface area than RP / Amsoil as well.

I have to get my oil changed in the 3500. I ordered the Amsoil 0W-40 and the EAO17 filter. Amsoil lists the Wix filter: 57060-EA and a Donaldson P-Series filter P550794-EA which looks like a larger filter than the Wix.

If you go with the preferred customer (6 or 12 months) route, it does drop the price a bit. $3 off per quart and $4 off the filter.

 

[OC455]

Got it in....now I need to get it done.

Amsoil EAO17 filter next to the OEM filter I just changed out. If anyone was curious. Reset the oil life and good to go for another few thousand miles.

I wanted to change the oil sooner but needed to get the oil first. Oil life was down to 11% and the odometer had 7040 miles at the oil change. 1st oil change.

One quick thing, on topic but off topic. Just got a 2020 ram 2500 with a 6.4. It had 650 miles on so basically brand new and I want to start this truck off on the right foot. If I use the EA017 filter and 0w-40 amsoil I shouldn’t have any issues down road warranty wise. This is an approved oil and filter?

Amsoil is not MS-12633 certified as far as I know.

If you want to stick with a FCA certified oil run Pennzoil Ultra Platinum.

Amsoil SS 0-40 is MS-12633 certified. Look at the data bulletin on their website under “Applications” page 4.

I have been using the EA15K50 since my truck was new in 2017. I have just recently changed to the EA017 filter. No problems with either filter. The longer one is a bit tougher to install as its a tighter fit (that’s what she said). I change my oil once a year, but I typically drive this truck <10K per year.

WIX actually makes the Amsoil filters per their specs. I used a filter for an F-250 for my old 5.7 hemi as it was considerably larger like the 017 filter.
