Donaldson P551132 Cut open - New

[Mewbs]

Donaldson is a pretty big name in industrial filtration, we have a few air filtering installation assemblies at our plant in a climate controlled room, never have touched their oil filters but have heard they are pioneer of synthetic micro-glass media that goes by the trade name Synteq. Their filters are normally rated at 99% at 15-17 microns depending on the size of the filter and 90% at 10 microns.

These go for 10 dollars a piece at FleetPride. Wanted to check these out for a while to see how well they hold up in automotive applications. You can get these around 8 dollars elsewhere online. These filters are pretty heavy for their small size, the can walls are thick, base-plate is heavy, the media is supported by a beefy coil spring at the bottom end & a nice thick gasket. Bypass valve is like a hard fiber material which should seal well when submersed in oil.

Counted 48+1 pleats which includes the metal crimp seam. The media endcap lip diameter is around 70mm with a endcap to endcap height of 2-1/8" Nitrile ADBV is a bit of a buzz kill for the kind of media this carries, its normally made for industrial equipment that is rated by the hour than miles. Its pretty a beefy ADBV so might be able to go 10K miles if you wanted to.

These are 3/4-16 threaded filters, should fit most Toyota. Bypass setting range is 11-17 PSI which is about the same as the FRAM Endurance FE3614. Cut one sample for the sake of science and for your visual entertainment. Enjoy.

At one of the combustion turbine plants I used to work at we swapped to Donaldson synthetic media oil filters. They helped greatly for particulate counts as well as extending filter changes from the paper media filters from GE.

Looks like a good little filter there.

Ooo...i wouldnt mind this for the race car that only sees a couple thousand miles at best per change

I've never had a reason to run one of their oil filters, but wouldn't hesitate to if I needed one. They're good filters.

Looks great! Along w/spec's.

Love that they are wire backed. Wonder if they make one that crosses to ph 3614

Unless I'm missing something the OP said that filter crosses to a 3614.

Good catch. Inched their website and OP is right.

Nitrile ADBV is a bit of a buzz kill for the kind of media this carries, its normally made for industrial equipment that is rated by the hour than miles.

Also probably used on equipment like hydraulic systems where the oil temperature doesn't get as hot as in an automotive engine.

Added some more pics to show its a direct fit. YZZD3 filter also cross ref to PH3614 from Fram webpage.

I looked up the specified vehicle/equipment, looks like their oil filter replacement interval is rated 500 hours.

Oh baby, look at that dome

Been running this filter for the past 2000 miles. Seems to be working fine, I did notice when starting the car after sitting in the garage for 2 days in weekends, the oil pressure light takes approx 1/2 of a second to turn off. My guess is the Nitrile ADBV probably leaks down a little, however given that the filter is mounted facing vertically upwards it doesn't seem to leak fully dry and still holds oil in the can.

This filter is 99% at 5 microns. That's the best I've ever seen. Though I doubt it's fitting anyone's personal vehicle. Too bad Donaldson doesn't manufacture more automotive filters using their Syntec media.

That’s a bypass filter, that’s why efficiency is so high. It only filters a small percentage of oil flow.

Good find but like mentioned you wouldn't want to use that as the primary filter. I agree that they need more applications on their filters.

 

[Mewbs]

Totally agree on that, I wonder whats keeping them out of the light duty automotive market?

Anyways I cross quote some past threads on Donaldson filters, Stude cut opened a Donaldson made Amsoil EaO showing the media looking identical to this filter, it has the same chocolate brown colored potting glue. Which was the reason I came across this part number based on thread size. I should credit @OVERKILL for this since his filter media thread has mentioned turned out to be true at some point before Amsoil switched to Champion Labs.

I'm curious to do a particle count oil analysis in the future just to see how well this does in the initial 5k mile baseline run and make a spreadsheet to how it compares to other filters in my stash.

Good Korning BITOGERS

Since I have 10 of these; thought I’d see if these are wire backed. We have wire backing!!

I don’t care if ADBV is nitrile either; louvers look good. Date code January 3, 2024 at 0309 AM. Enjoy the photos.

Got a particle count report from WearCheck this morning on the oil running this filter for the second half of 5K at 10,600 miles. Oil was directly sampled from the clean side of the filter.

ISO4406 cleanliness code : 19/18/15

Particle count > particle size range

3158 > 4 microns
1720 > 6 microns
293 > 14 microns
99 > 21 microns
15 > 38 microns
2 > 71 microns

I delayed in cutting this filter open since I was shopping around for a microscope or probably sending it to a special guest.
Will post the full oil analysis report later at the appropriate section.


Pictures of the pulled filter:

Finally some weekend downtime to change the oil on my daily driver, 2012 Toyota Yaris. 153260 Miles.

What came out: HPL Passenger Car PC5W30, was in service for 10600 miles. Donaldson P551132, was in service for roughly 5000 miles.
What went in: HPL Super Car PC5W40SC, Fram Endurance FE3600.

Base plate SmCo magnets caught some stuff, although very little, wiping them off on the shop towel revealed quite a bit and putting a magnet over them lifts the paper a little!

I'll probably send the filter out to a special guest or cut it open myself in a week, really looking forward to see what it caught.

Magnets arrangement on the new filter. This took me a little longer than expected since I had to clean off and reuse the magnets from the Donaldson. If you're curious these magnets size are 3/8" diameter x 1/8" thick.

Oil sampled, pretty certain it can go longer but I still want some base line mileage numbers before pushing further. As dark as it looks here, the oil on the dipstick looks clean reddish amber.

Takes about half a quart to prefill the filter. Took a whiff from the bottle and pitcher, there is that similar distinct sweet smell unique to HPL motor oils.

View attachment 233632

Big filter, but only half inch sorter than the Titanium FS3600, doesn't hang beyond the oil pan.

I start her up and noticed immediately the car sounds strangely quiet on idle. Normally there is little valve train nose on start up idle until fully warm/hot. First time running xW-40 grade oil on the car.

That's a good PC, but would be expected with a filter that efficient. Plus, all the magnets probably also helped since they catch a lot of the ferrous debris that even that efficient of a filter can't catch all of.

Yeah they certainly help a bit as wiping them on a shop towel revealed a thin layer of black dust caught by the magnets. Anyways im a little sad i cant buy those SmCo magnets anymore since its been out of stock for months. Should have bought a bunch back then.

Dipstick and blot paper testing showed the oil in great shape for 10,600 miles. You would be suprised how good the wear levels are with the oil. It had a tbn of 9.33 but thickned upwards to near 40 grade. Iron was the only wear metal that trended upwards linearly with miles. The oil could have gone 20k easily.

Filter cut open. Unfortunately found a small defect on one of the pleats was poorly potted with a fold on the end, probably explains how small amounts of larger particles got through. Filter did its job in keeping smaller micron particles in check the least.
