LML / Donaldson DBL7483 Oil Filter Conversion

Well, I did it... I've convinced myself that the Donaldson DBL7483 is the way to go for Duramax oil filtration. It wasn't easy, but after viewing nearly ever oil filter made for the Dmax and all the lies and inconsistencies in these "consumer grade" products... I made the jump to professional grade products and ended up with the Donaldson (over the CAT filter)... and here it is.




It comes wrapped in a heavy plastic wrap, much thicker than the consumer grade wraps. Cutting this thing open was extremely difficult, even with my filter cutter! Once inside its very basic, just the element and the assembly parts. In ALL the Donalsdon literature they show the media as being "Blue", it was kind of a bummer to see it "White".

BUT... look at it closely.

It appears to be the same "terrycloth" looking filter media I found in the Amsoil EAO 52 oil filter, but at a slightly lower micron rating. Donaldson and Amsoil have a well known relationship, and it looks like this filter media is found in both products!

As for the element itself, it's constructed PERFECTLY. Not a single pleat is out of place, no glue , no rust, no mess.... It borrows those 'Locating Tabs" as seen in the Fram filters to locate the element perfectly in the can, and has a louvered center core to protect the element media from tears or abrasion. There is no way to improve it !




The media is synthetic which offers the highest possible flow rate while being able to catch the smallest of particles.
The micron rating is 10 Microns at 90% and 15 Microns at 99.9%.Outstanding!

The huge media area combined with the high flow means the bypass valve is not needed. 100% of the oil sent to the filter gets filtered...100% of the time. This played a big factor in my decision.

Installation is slightly different from my LLY. The LML filter mount nipple has a hex portion made into it. Simply unscrew the original nipple with a 15/16" socket, and screw in the new one. The swap takes 30 seconds...





I'm going to run this deal through TWO DIC countdowns ( aprox 15,000 miles) and send the oil in to Blackstone for a check up. I know the oil should be good, and with the huge area of the filter, I'm pretty sure it can make it too. After swapping filters, I needed to add 2.5 quarts of oil to bring it back to FULL. Adding volume to system is always a good thing.

So there ya' go..... Make your own decisions based off all of this. For anyone thinking about doing one of those Amsoil dual filter mounts ( 1 full flow, 1 bypass) ..this Donaldson deal offers nearly all the benefits for a fraction of the cost. For anyone who wants to keep a OEM style filter like the Baldwin... that's great too, especially if your still under warranty.

The mounting nipple is $16 on Ebay, and the filter is available everywhere for about $18. ( I put the OEM nipple in my glovebox, in case I'm in the middle of nowhere and need to swap it back)

Thanks for your work on this subject. Just curious is there a special adaptor needed to use these filters on our trucks? Sorry for the question I just am nit that well informed.

Can you add the part # for the nipple as well.

There is a oil filter condition known as "Pressure Drop" where the restriction of the filter will lower the pressure on the outlet side, when compared to the pressure on the inlet side.

I just finished dinner, and pulled my truck out of the garage. I have over 100k miles on the LML, and know the truck very well. I have never seen the oil pressure this high before!



The coolant temp is about 160 degrees, and at 2k rpm, it's somewhere in the 75psi range. Normally, it would be 60 psi, right on the dot.

The ultra low restriction of the Donaldson synthetic media PLUS all the added surface area has made a big difference in the filter pressure drop, when compared to the M1-303A.

Another win, for Donaldson.

I have one more oil change using Amsoil and Donaldson filters that I purchased a couple of months back. I did just order the adapter and will make the swap over to the larger filter next time.

The description says it installs with a 1/2" socket. Is this correct and how much torque did you put on it when installing it?

The adapter is broached to accept a 1/2" drive ratchet. I put the adapter in the freezer overnight before installing.

Then thread it in until it bottoms out, and then I gave it a final "Umph".

I'm guessing about 20 ft/lbs.

Thanks for time and effort. Great write up. Like larger filter area. My only concern is the 15lbs. Higher
pressure. Could this be because oil isn't up to temp?

Nice work Bob. I take it this will also work on the LMM with the same adapter?
