Where to buy Donaldson ELF7349/15?

[DFrank]

I see folks saying they can buy these for $10 or some such. I'm seeing $24 when I search, anyone got a source to share?

Or other high end filter on the cheap?

Also, I just read someone saying they go 15-20K on their oil and change the filter half way through.

I do oil and filter at 5K. Am I throwing away good oil? It looks black enough when I drain it, but I really don't know.

Running rotella 15 40. Got 185K on the odometer.

I have order fleetguard filters from geno's garage. fleetGuard are OEM Filters. if you look in the Digital Magazines on this site, issues 55,57,71,76 , they have great information on oil

I have ordered more then several times more then several times from these guys--

They carry Donaldson and many other brand filters.

They have great customer service and quick shipping and are a vet owned company.

Their website CAN be a little difficult to navigate at times, but if you simply use their search box with a part#, more often then not you will find what you are looking for. ALternatively, give them a call and they are super helpful.

I believe the standard service interval for 03 is 15k miles. 5k is more along the lines of severe duty schedule. It all depends on your driving conditions. Extreme heat, running heavily loaded all the time, and short runs where the engine doesn't get the chance to reach operating temperature all effect oil life. 5k miles is more on the conservative side unless your conditions are similar to what i listed above.
I run 20k and change my filter at 10k, but I also run a full synthetic and I monitored closely with oil analysis to track the amount of additives remaining. I could safely go further but 20k is about what I put on my truck in a year so I stick with that number and do one analysis a year just to monitor engine health. If you don't want to be hassled with all that you can safely run to the mileage recommended in your manual and pull the plug and refill.

Go to most class 8 truck dealers they have them in stock, I go to the Freight Shaker Dealer in Missoula to get mine

 

[BDaugherty]

I now buy my Fleetgaurd filters through my local Kenworth dealer, but prior to that I bought from Geno's. They have fair pricing and if you buy a year or so at a time, it cuts the shipping cost and hassle.

You described the Schedule B in the '03 Diesel Owners Manual which is 3,750 miles between changes. Schedule A oil changes are at 7,500 miles.

Thanks for the correction Bill. I thought 03-04 went to 15k and then with the 04.5 design change was reduced back again.

Since you own an 03 I believe you are the wrong man to pick an argument with

Hey, no argument from me. I didn't want the OP to think it would be ok to run 15k on an oil change. Personally, I split the difference and change at 5k or one year whichever comes first and it's easy to keep up with it too. KISS works for me.:-laf

With the early CR engines I'm sure it would be no problem under normal driving conditions but if it is beyond the manufacturers recommendations it needs to be done under the guidance of an oil analysis. I do one every year on each of my engines just to monitor my vehicles health and at 20k mile intervals on both the wife's TDI and my truck there is still lots of oil life left.

HOWEVER, the KISS method is much simpler

I agree. I know of a couple of members who use extended oil changes on their early CR engines and have been successful running high mileage using synthetic oil and oil analysis. I don't put a lot of miles on my truck and several times the one year lapses before I put 5k miles on it. My 11 year old truck is a dedicated slide in truck camper hauler and has barely over 40k miles on the odometer. It's a dry pavement/garage queen.:-laf

I change mine at 10000km (62100 miles) so its easy to keep track of. Don't have the nanny minder to tell me like the new ones do:-laf

 

[amsoilman]

A Donaldson ELF7349 is a very efficient oil filter.................98.7 % @ 15 Micron(Rated by International Standards Organization 4548-12). as I last seen printed on the filters. If you are using a high Quality Synthetic oil and utilizing this filter, you should be able to extend oil changes beyond 10,000 miles. If it were me, I would do a( UOA) Used Oil Analysis at 5 K and another at 10 K. This would tell you the whole story on extended oil changes. As far as "black" oil is concerned, black is not an indicator to determine oil changes!

Somewhere above you have a "0" out of place, which is it ???

 

[DFrank]

Thanks guys. I've heard of UOA, but what does UOA cost and what does it really tell?

I had decided a long time ago it was most cost effective to change it at 5K, but haven't thought much about it since deciding that.

It seems I am short the full part number. Is this the one?

Part Number: ELF7349
Replaces Part Number: 10521
Manufacturer: DONALDSON

Yes, that's the one.

In my opinion, if you like how your truck is operating, keep with the 5k mile OCI's. I don't think UOA's are worth the hassle. 3 gallons of Delo Multigrade costs me $40 and last I checked, a UOA cost $30 plus shipping and time. What's the point? Just change the oil and move on with your day.

I also use filterspro.com for oil/fuel filters and usafilterstore.com for air filters.

 

[amsoilman]

A complete UOA will generally cost between $20 to $30 Dollars. When a complete analysis is done, there are many results such as Viscosity, Additives, Wear metals including Iron, Aluminum, Copper, Tin, Chromium, Lead, Nickel. All contaminates, such as dirt, Fuel Dilution, Soot, Water. It would also include Acid Number, Base Number Oxidation, Nitration. Basically, a UOA is likened to a Complete Blood test, so will not only tell you the condition of the oil, but will also tell you how well your engine is wearing internally, and can warn you of impending problems before a breakdown occurs.

Thanks for sharing that seafish, I just placed an order with them. I bought several Donaldson oil filters and baldwin fuel filters for less than the Wix filters I had been getting through rockauto.

I also use filterspro.com for oil/fuel filters and usafilterstore.com for air filters.

I have pulled many oil analysis samples for customers of mine, and I have seen several that have actually saved the owners big expenses due to some issue within the engines! EXAMPLE: One had so much "FUEL dilution" (10%) the oil was a 30 grade instead of a 40 grade oil. Another was an issue with dirt coming from a cracked air intake hose that was not seen unless the intake hose was removed, which allowed dirt to bypass the air filter. Just changing oil, these types of issues would never be seen. Granted, there are some indicators the owners may have been able to see, but the fact is they didn't!
