I use a 2 quart filter, Donaldson P550299


EDIT: https://dynamic.donaldson.com/webc/WebS ... tem=193203

I forget the DIY brand equivalents, but I'll cross it for you on Monday, if you need.

 

I have a Mobil 1 on there right now, can't remember the pn (204 or 402 or something like that) but its whatever the Mobil book said I needed. It replaced a K&N filter, I didn't notice any size difference between the two.

 

I use the Napa gold #1515 . The 4.0L can use the ford type FL1A and all equivellent it seems

 

MOBIL 1 = M204, or M301 which is the same as K&N HP3001, Motorcraft FL-1A or FRAM XG-8A (Extended Guard, silver can)
Hope it helps.

 

Hi,

Mobile 1 with Mobile Synthetic oil every 3k (replaced the Mopar on the first date I got it). 05 stone white Rub.

I just installed a 301 Mobil1 oil filter.I did a bunch of reading on oil and filters at "Bob is the oil guys site" Also am trying the Mobil1 5w-40 Truck and suv oil because of all their oil testing they have done on the 4.0l jeep engines.I am a diehard Amsoil guy but what the hell.

The jeep takes the Amsoil SD15 filters or you can run the larger SD42.The 301 Mobil1 filter is about 50% larger than the Amsoil SD42.

Hi
I am also using Mobil 1 5w-40 Truck and SUV oil.
You might want to look at the Baldwin B2 HPG oil filter, it is almost identical to Amsoil SDF series.

What's the reason for 5w-40 Truck and SUV?

 

I was intrigued by DoctorD's Donaldson listing and cross referenced his filter on-line to a Wix 51773. This Wix filter is available at my local auto parts store for $7.98 (jobber price) and according to Wix has a 'nominal mirco rating of 30' (30 Mircons?). The rest of the specs on this filter:

Measuring under the hood it appears that I have plenty of room for a filter about 7-inches long, about the length of the Wix 51773 and P550299 Donaldson. I like the Donaldson idea, but availability may be an issue (cost too?). Is the above Donaldson a synthetic media filter? Is the Wix 51773?

I have been using the standard length Wix/Napa filter 51085 which is about 3.5 inches long, obviously holding less oil.

The question is, is the 51515 better/more correct than the P550299 Donaldson, or Wix 51773 equivalent? I have to think not, the cost alone makes one think the Wix 51773 is a better filter than the 51515 (if it is not 'wrong' or unsafe for the 4.0L application).

I use a synthetic media oil filter for my diesel (Fleetguard) and would for the little Jeep it I could get one.

DoctorD: how much extra oil do you need to add for that larger Donaldson filter, 1 quart?

No. The P550299 (wix 51773) isn't synthetic, nor is the P550008 (wix 51515) They DO offer a synthetic stock length filter, though:

I haven't the engineering data on the Donaldson, but we use the 550299 on all V8 gas Dodge Ram pickups and vans. I do lots of handicap vans and see several that have 250k on them. No engine issues yet on the 5.2 or 5.9. I can't fit this one on my 5.2 Dakota, but the 550299 fits well on the Jeep. I'm more concerned with quantity of filter element. I cannot see the media being different between Donaldson's P550299 and P550008 filters, since they're both identical Ford application. Maybe the Wix listing is wrong. I have to contact Engineering to find out. Give me some time on that one.

DoctorD: how much extra oil do you need to add for that larger Donaldson filter, 1 quart?

Almost 7 quarts with this filter. The stocker holds about half a quart, the extended one about a quart. If you need to source the synthetic filter I listed above (P169071), lemme know. I'll sell them in case quantities, but I'm sure you can get them from the AMSOIL people, they love Donaldsons as well. Almost every AMSOIL site has Donaldsons listed as well.

 

Nice reply DoctorD.

I like the idea of adding capacity and using a very high quality filter. A 7-qt oil capacity is better than 6. I'm currently using a 5,000-mi. oil change interval with Mobil 1 5w-40. I may do some oil analysis in the future to see if I can or should extend my intervals (I don't mind changing oil or spending money on it) and having the extra quart of oil on-broad won't hurt. Most of the time 5k is a nice interval for me, but I can foresee longer cross-country trips where I might want to run the oil longer. (Changing oil when on a trip can be a pain and I don't like to let other people do it for me.)

Your observation that the Amsoil guys like Donaldson filters (and the new air filters in the 6.0L Power Strokes) leads me toward this product if in fact it is superior.

I have one short/stock Napa 1085 on the shelf in my shop and that will likely be the last one I use as I want to run one of these longer, possibly better filters. SEarching on the web today I started compiling a list of oil filters for the 4.0L I6. I started with the Wix & Donaldson numbers and cross-referenced them on other's web sites. If you guys see something that is wrong speak-up

Any opinions on Baldwin filters?

I dislike them.

I've cut them apart before and find they make a few critical mistakes. They also play games with their filters....For instance, a Baldwin fuel filter for 7.3 powerstroke eliminates the OE cap on the housing. So, if the driver or mechanic doesn't save the old one, you're screwed when you try to change one on the road. Same for the R90P racor, they eliminate the bowl. They do this with all their separators, even the 6.9 7.3 IDI diesels. So, a number can cross reference one way, but not back.

They often forget to seal the top of their oil filter elements to the housing too. So do a great many others. So, a decent element is wasted since the dirt can bypass it entirely.

I have some pics around somewhere I can dig up and link if you wish. I cut apart 3 Powerstroke oil filters and posted them for all to see on a (members only) technical forum (http://www.iatn.net).

I have about 5000 automotive oil and fuel filters on the shelf here and do about 600 gallons of oil a month, Filters are a pretty important part of my business.

WIX is actually DANA and they are OK, not great. Believe it or not it varies greatly depending on the actual filter part number, since almost EVERY filter maker out-sources certain part numbers entirely and simply re-labels them.

If you do your oil sampling,I can help you interpret your results. We test new and used oils here.

 

Amsoil is now using a full synthetic media in their filters "EA Filters" I thought the SDF line was a synthetic/paper media like the Purilator P1 and the Baldwin HP lines. Whats crazy about the new Amsoil line is the run time 1year or 25000 miles! The problem is Amsoil is the only oil I know of that has a 1yr/25/30k mile change interval.I went with the Mobil1 301 because it is a full synthetic media but I dont think I would run it 1yr.I`m just going to do the 6month/7500 mile thing.I only put on about 5k a year in the Jeep.I do think Amsoil is a superior product but for the money and ease of aquiring I feel the Mobil1 filters/ 5w-40/Delvac 5w-40 are pretty close at around half the price.

The new Amsoil filter does look pretty kick ass though 8)

Thanks to someone on this site,this is the most oil/filter anal site I have ever found....and I thought I was bad :laugh:

Heres another good/recent one http://www.oilfilterstudy.com/

Bill

 

Good to know about Baldwin. I think I have only used one of their filters yeas ago. For 'automotive' (wife's car) I have been using Wix for years and for my Power Stroke I have mostly used Fleetguard oil filters, but Wix air filters (and Racor/OEM fuel filters).

I was thinking of using Fleetguard for the Jeep and cross referenced some numbers and even called my local Cummins Rocky Mountain dealer yesterday to see if a strata-pore synthetic media filter upgrade was available for the longer 4.0L filters but apparently not. Fleetguard LF697 (a Ford# cross-referenced Wix 51773) $7.78 @ Cummins Rocky Mountain.

Are those "Amsoil" filters really Donaldson's? I found a source for Donaldson filters at my local CAT dealer. If that is one of the best, or just much better than Wix (DoctorD) then I will use Donaldson.

Donaldson?
Fleetguard?
Others?

It is interesting that in most (all?) of the oil filter tests found on-line Fleetguard's filters are not being tested. Too rare and hard to find?

Dang, I was hoping nobody would burst my Fleetguard bubble? Now I'm leaning toward DoctorD's Donaldson P550299 now that I have found a local source. I can purchase them for $7.87 each.

Anyone have anything bad to say about this filter or Donaldson in general? DoctorD, do you have more positive to say? Why you use this filter on your Jeep or use other Donaldson products?

I did find some Donaldson info on Amsoil sites as you said. I'm not a big Amsoil user (have been in the past, but using other stuff [Mobil 1, Red Line, Delo 400 now] but Amsoil's endorsement and 'focus' on quality is another reason to consider Donaldson.

I found this on Amsoil's Corporate Website:

Donaldson Filters
AMSOIL is now introducing the P-Series of Donaldson filters to compliment the Endurance line. The expanded offering of filtration products features many applications that differ from, and several that coincide with the Endurance line. Donaldson P-Series filters offer premium filtration at a competitive price. AMSOIL now stocks all of Donaldson's most popular filter applications.

Donaldson P-Series Lube Filters (order)
Increased engine emissions control and tighter tolerances within the engine require high efficiency filters.

Donaldson P-Series filters are constructed with full synthetic or synthetic blend media for high efficiency. The media is embedded deeper into the sealing plastisol than conventional filters, allowing better sealing longevity. The lube filter can is constructed of heavy gauge steel, with many models having domed tops that provide superior pressure fatigue performance. The center tube allows more flow without compromising strength, and the louvered design eliminates tearing during pleat movement. The can and base plate are I assembled using a fully tucked seam, roll-formed threads, a nitrile sealing gasket and a compression spring holding all the components in place within the filter.

The nitrile ADBV is very large to cover the large pattern of baseplate holes. The bottom endcap has dimples on it to keep the filter centered in the canister.


Dont forget that I am no expert I am just trying to help with your decisions after all thats what the internet is all about...information.THe problem is that some people put wrong info out there.There is alot of info out there on this subject the 2 links I provided are pretty good ones.As with all things do your research double/triple check resources and you should be able to make an informed choice...and sleep better at night :laugh:

Donaldson is about the most widely recognized worldwide filter manufacturer in the WORLD!. They are innovators and pioneers in air filters and really understand filtration. Nobody really knows about them in the retail segment since they are an OEM supplier, making many filters and housings for the original manufacturers of vehicles and industrial equipment. They are the most widely recognized and accepted filter maker on the engineering level and OE tier 1 supplier list.

They simply don't market to the public on the retail level. They won't be wasting their money putting their name on race cars, trying to get endorsement for their products so that they can sell them onesy-twosey in Wal Mart or AutoZone. They won't be loading their filters with colored paint and grippy **** at the base so that people with no tools and experience can find it under the hood and get it on and off.

They do a LOT of R&D. Google "Donaldson" and see.

Why did I put one on my Jeep? Becuase they are a decent filter and I stock thousands of their filters now. I already had them on the shelf. I chose to stock Donaldson because they are original equipment on the heavy trucks and cranes, drill rigs etc that I work on. They make most of the filters and housings for light, medium and heavy trucks. They make most of the intake and exhaust systems as well, mufflers and hangers, etc.

Your Powerstroke (depending on the year) has a Severe Duty AIS kit, Ford # 2U2Z-9K635-AA. That is a Donaldson Powercore. That's the filter AMSOIL loves and considers it the end-all be all for this vehicle.

Could you retrofit one to the Jeep? No comment. 8)

24 ounces per minute flow at 10PSI with room temp SAE30 oil isn't good flow. Something's messed up there with the numbers, no?

 

Check out the link.. http://www.oilfilterstudy.com

I think the flow rate is a calculation of some type with the bubble tester



Heres a link to a spread sheet on the testing results..

http://www.oilfilterstudy.com/Grease%20 ... 0Study.xls

One thing seems to be apparent...the better the filtration the lower the flow.Which makes perfect sense.The big question is what is the cut off.If your starving your engine on startup because of the flow restriction where is the benifit.I can see how going to a larger filter to compensate for pressure drop and increase over all filtration capacity.I have noticed that when starting the Rubicon that I have about a 2 second delay on oil pressure rise compared to about 1 second on the larger than stock SD42 Amsoil filter.Running pressure seems to be the same though I am just going by my sweep meter not a calibrated psi gauge.I`m sure alittle of that comes from the heavier 5w-40 weight oil as well.



Also I would like to add that the Donaldson "Synteq" media used in the Endurance lines seems to be what the Amsoil next generation filters are using! So the Doctor has hit the nail on the head...but does Donaldson make a Endurance filter for the 4.0? If not getting the new Amsoil filter should be the same deal. The filter in the test is not an Endurance filter it seems but the standard line.

I cut apart USED filters, and see almost EVERY Baldwin without internal bypass has split the pleated element due to plugging (and resulting pressure drop). Their filter media is very tight, almost identical to AMSOIL's. This means there might be such a thing as too much paper.

Yeah, they offer a SYNTEQ media P169071.

I'll stick with the P550299, based upon what I see when I cut apart filters that have been in service and have too tight a media. I'll focus on quantity of contaminant trapped, since my used oil analyses on Dodge 5.2 and 5.9's running this filter show very little wearmetals when regularly sampled and looked at over 250k miles (and using plain ol' mineral oil!). It's apparently good enough, and doesn't risk splitting open internally and dumping unfiltered oil through the mains until the new filter's spun on. VERY important if trying to extend drain intervals. Capacity must be increased with an extended drain interval, ESPECIALLY if filtered particle size is reduced.

 

CamperGuy:

Not that I specifically doubt the info you posted about the Fleetguard and Donaldson filters but it is interesting that both summaries say both filters have good flow but only fair filtration. These are both supposedly above average brands/filters. Which filters were good at both flow and filtering in the tests conducted by that tester?

I like your thinking and 'real world' testing, cutting open 'used' filters. You have saved me from a possibly costly mistake from trying Baldwin. Surely filtering and and flow rates are a balance. Your comments regarding the Donaldson Corp. are well received and I was already slightly aware of their focus. Just because a company doesn't try to mass-market itself doesn't deter my interest. In fact, this may even make their products more intriguing. I don't mind seeking specialty, high quality parts. Heck, the filter you are using (P550299) purchased from my local CAT dealer is about the same price as a comparable Fleetguard or Wix. As you know, the heavy-equipment and trucking industries are more in-tune with extreme service, extended drain/service intervals with a focus on not sacrificing longevity or durability.

For lack of better or different information I think I will order and try the same Donaldson P550299. At least I know someone who is using it (on a 4.0L I6 Jeep, correct?) compared to the Fleetguard LF697 or the Wix 51773 which are numbers that I found from cross-referencing your Donaldson P550299.

My Power Stroke is an old 1996 model, and I have been using a Wix paper air-filter which I replace every 10k or sooner (particulate/dusty environment). The Power Stroke Donaldson filter I was referring to was on the new 6-liter Power Strokes. It appears to be a very good air filter! For oil filters I have used a few Motorcrafts, Fleetrite (international old in-house brand, which were relabeled Fleetguards I think, now they just sell Fleetguards) and now Fleetguard.

Conclusion

Good construction, good flow, good filtering

In the low-priced group, the AC PF, Purolator PremiumPlus, STP, and SuperTech appear to be good choices. These four filters are "best buys" because they doing most things well and are in the low-priced group.

In the mid-priced group, the Baldwin and WIX appear to be good choices. Both have construction that is excellent.

In the high-priced group, the Amsoil, Mobil 1, Fram XG, and K&N appear to be good choices.



Excellent filtering

The Fram TG and Purolator PureOne have excellent filtering. They do flow less than filters with less filtering. Both are in the mid-priced group. The AC UPF also has excellent filtering, however, the UPF1218 is no longer manufactured. The UPF series does include other filter applications that are still available.

Excellent flow

The Hastings, Donaldson, and Fleetgard all have excellent flow. Not surprisingly, they are also have larger pore sized media. The Purolator PremiumPlus and Amsoil flow less than these filters, but still better than average and have good or very good filtration.

One thing I am curious about is the filter media splitting...isnt that what the bypass is suppose to prevent ? I also agree that any filter will do my brother inlaw has a 82 Toyota pickup I think,with over 400,000 on it and he runs whatever oil is on sale and ditto on the oil filters and hes lucky if he changes it every 6 months

Oh and to get to jp33 question...The 301 is the larger sized Mobil 1 filter Bob the oilguy actually stopped using these on his Jeep because of a slightly higher iron"I think" reading on his oil anaylsis and went to a higher flowing filter...but I cant get back into the site,lol

"I also agree that any filter will do my brother inlaw has a 82 Toyota pickup I think,with over 400,000 on it and he runs whatever oil is on sale and ditto on the oil filters and hes lucky if he changes it every 6 months"

Yep, we can obsess about getting the best filter for our application but just doing some maintenance seems to work well for many. And with an engine with a great reputation for longevity like the I6 4.0L we are probably just helping guarantee reliability as long as we don't have a 'freak' problem.

Instead of my local CAT dealer who would have had to order the Donaldsons, or my local Cummins dealer who would have had to order the Fleetguard filters for my Jeep, I found another source. A fleet lube supply type business that spun-off from a commercial/fleet truck parts business several years ago still has some Donaldson filters on the shelf even though they don't really sell parts anymore.

They had 10 of DoctorD's Donaldson P550299 filters on the shelf. I bought five for $6.56 each, which seemed quite inexpensive. Obviously I will be using this filter for a while with my 5,000-mile oil change intervals.

"Almost 7 quarts with this filter. The stocker holds about half a quart, the extended one about a quart. If you need to source the synthetic filter I listed above (P169071), lemme know. I'll sell them in case quantities, but I'm sure you can get them from the AMSOIL people, they love Donaldsons as well. Almost every AMSOIL site has Donaldsons listed as well."

The P550299 is not as large as I expected, maybe the other optional filters are a little bigger? I bet it will still be nice and easy to install. If I can squeeze an even 7 quarts into the crankcase without overfilling it with these new filters I will be happy
