Two 7.3L Powerstrokes, 16.5 quarts each. I change the filter every time I change the oil, about every 6k-7k.Same movie here but I also change the oil in the upper resivor and heads for 3 more quarts. See Bill Hewitts powerstroke.com and Fuel system maintence section(free video series).I did it and about crapped my pants at the horrible grease like goop that came out of that resivoir.I've done that maintenece procedure a couple of times now,I could tell a big difference in cold starting after doing so.

Fuel filters (engine and frame rail) every other oil change.
Air filter every 50K.
Drain water off of water separator every oil change. Got into a batch of bad fuel once and I was draining it every 50-60 miles or so.
Then you got trans filter(s), too. My required Mercon SP fluid is high $$ synthetic stuff.

3,500 miles each. Fleetguard Filter. Delo 400 15-40. 3 gallons.
Fuel filter gets changed every other oil change. Fleetguard filter again. I drain the filter bowl completely every time. Every other time, I clean out the filter bowl with Brake Clean green. You'd be surprised at the color of the brake clean coming out the drain tube to the catch bottle. :o
No on the oil analysis. People I know with other Dodge's do and go as much as 12 to 15k on an oil change before analysis start show oil break down. I just can't do that. Analysis OK or not, it just does not sit well with me to run that many miles on the oil. Oil is too cheap, really.
Post by: gutsnthegrass on November 06, 2013, 11:30:38 AM
13 quarts 5W40 synthetic Rotella every 4000 miles
Ford oil filter
They recommend fuel filters every 10-15K
Drain fuel water seperator every 1000 miles.
I change the oil myself, it runs close to $100 every time with filter.
I sold my 2001 7.3L a year ago, great truck and I would change the oil every 5000 miles with Delo 15W40.

I get the oil changed at Grease Monkey about every 4,000 miles. It costs me less to have it done than I could buy the oil for (15 quarts plus filter.) They vacuum out the interior, check all fluids (top off when needed) grease U-joints etc. I can't buy the materials to do it myself for what they charge.

This might work, if not click on 7.3 and its the injection tune up series in the longetivity module. I made a vaccum canister out of a half gallon canning jar with a homemade copper lid and some soldered tubing,I used my 6 horsepower shop vac for the suction,Worked very well.Redneck hillbilly factor of about 6.5 of 10,I used 3/4 tube for the suction supply power and 1/4 for the dip tube down into the resivoir and into the jar.My buddy who gave me this info tried a turkey baster and said it was a huge PITA.The shop vac works pretty good I think,performs about on par with the pump used in the videos from hewitts.Some negative net reveiws on whether you really need to do the upper change,but my truck had 220k on it when I did it and I had changed the lower first and then sucked out the upper,FLAT out NASTY looking paste/grease,coked up slurry,it got better with each quart added.and I noticed a big difference in the cold weather starting ease.

My '11 Duramax uses 10 qts and I change it by the oil life monitor. Usually approaching 10,000 miles
The Cummins and Duramax are both very easy on engine oil and will run a long time with whatever 15w-40 you want to run.

My '99 f-350 7.3L got a new filter and 17 qts of DELO 400 every 5k....
I had an aftermarket intake and turbo/exhaust. I CLEANED the air filter every oil change. also drained the upper resevoir as previously mentioned.
I flushed the tranny and changed the filter at 200k. MAKE SURE YOU REALLY TIGHTEN YOUR HOSE CLAMPS!!
I lost a hose on the freeway and really burned up the tranny. It was getting weak already but that was all she wrote after that.....
rotate your tires when you change your oil.
I also ran 1 small can of seafoam every couple tanks of fuel. Change your fuel filter at least every 50k.
AND WATCH YOUR BALL JOINTS/WHEEL BEARINGS/OIL SEALS IN THE FRONT AXLES.
new wheel bearings and seals are very expansive.
I bought my truck from a friend and knew it needed a few small things.
Wound up being ball joints and tie rod ends.
Wheel bearings and oil seals
tranny pan seal. Crank Position Sensor. Wheel speed sensors. and a new Murphy switch for the propane injection.
had to pull the turbo pedestal out and I removed that little return line bypass thingy...helped a lot with oil seepage.
Later on down the road was a brand new 10.5" sterling rear end, and a transfer case shift motor.
ALL YALL BE GLAD I WAS SMART ENOUGH NOT TO TRY TO SELL IT TO A MEMBER ON HERE. Next time I get a one ton. I will put a leveling kit on it and a locker in the front end other than that its staying stock.

So, I see many with cummins are running 7k to 10k between changes. Why? Synthetics? Isnt that a little long? Maybe Im wasting $ at 3k to 5k intervals? I use Delo and sometimes Rotella if cheaper. Delo 15-40 my favorite. Does anyone lose/use any oil at such long change interval? I drop half quart at 4-5k.
You have the manual for your truck?
Cummins recommends a 7500 mile oil change interval for severe service. They recommend 15,000 for normal service. That's with regular conventional oil.
If you can't trust the people that design and build your engine to know how long you can go between changes,who you gonna trust?

05 cummins. Thats just it, You cant trust them. Jeez they cant even put a quality fuel filter on it. Sandblasting the injectors isnt good. 2-3 micron is what Cummins told Dodge. We got 6-7. :bash: I do have a manual yes but at 4k the oil is horrible it seems. Maybe its the injection events causing it? Just curious on others opinions on intervals.
Why do you think its horrible? Because the oil is black?
The oil in my Cummins was black 30 seconds after an oil change. That doesn't mean the oil is bad,that means the oil is doing what its supposed to do and has the soot in suspension.
IIRC the 2 micron spec is from Bosch,not Cummins or Chrysler. Its not Bosch's or Cummins' fault that Chrysler warranties the injectors and can put whatever filter they want on the engine.

What? Maybe its Cat not Cummins. Doesnt Bosch make the injector and instruct proper filtration for their part? Does Dodge listen?Of course Cummins doesnt put 7micron filters on their stuff right?. Dodge warranties injectors just long enough to clear crap filtration damage. 150k failure common. Much longer with filters at 2m. Hmm. What the heck does Chrysler know about diesel? Nothing except how to clear warranty period as cheap as possible. So no I dont trust them much. :sry: Ya it gets black immediately but how much is to much? I was just asking. I never ran any engine 10k on oil so seems odd to me. Some one who tested the Delo oil at say 5k and then 10k would have some real info on oils properties at time of miles/hours ran.05 cummins.

Go talk to a truck shop and find out how many miles are on some of the trucks coming in. You might get a surprise when you see a million miles and more commonly and guys getting the oil changed every 30-40k whether it needs it or not lol. Delo 400 is good stuff, I wouldn't use anything else. We recommended 10k minimum on all diesels, black oil is no way to judge.
For pickups I would drain the water separator almost every time I opened the hood and change the filter per manufacturer's spec, usually 30k.

I was pretty amazed when I did an oil change on a Kenworth after 40k and thought their owner was nuts until I looked at the odometer, it was at 1.6 million and counting....
I would definitely not be changing your oil before recommended interval and I would ditch the motorcraft oil for delo.
Post by: Rick on November 09, 2013, 12:44:10 PM
My 7.3 powerstroke would start to breakdown after 5k. Idle would start to roughen slightly.
Powerstrokes are the one diesel I'd change oil sooner on. The PS uses engine oil to fire the injectors. Because of this,the oil in a PS gets hammered in comparison to a CTD or Dmax.
Finding used oil analysis reports isn't difficult. I'm sure Bobistheoilguy.com will have some for a CTD. Any of the major CTD forums will have UOAs to read as well.
Or you could just run your own UOA. Blackstone Labs will send you out sample kits for free. Pull a sample at your next oil change and send it in with $25 IIRC. They'll tell you exactly how much life is left in the oil at whatever interval it was pulled,and make a recommendation for the length of the next interval. You'll also be able to see how well your air filter is filtering,if there is antifreeze in the oil,or if there is any fuel dilution.
Oil analysis is just another tool.

As another member posted, you might want to check into your glow plug relay. I sounds like that is your issue with the cold starting issues after 10-12 hours between starts below 40 degrees. It is a really simple fix and only $80 or so.

bit expensive but they say the engine gets quieter with the moly in the oil it coats all the parts in the engine and it runs smoother/quieter.
I might do it, I advanced the timing on my engine a little bit so it might help
http://www.schaefferoil.com/ (http://www.schaefferoil.com/)
I was quoted about $500 for a complete lube change out to synthetic schaeffer's oil - including the T-case and both diff's with moly oil.
The auto trans would also be changed but that wouldn't be the moly stuff obviously.

KF....make sure if you get Schaeffer's to get it through the local rep. I believe he is in Kent. Name is Ray. Just go to the website, upper right...find local representative. Takes you to a page where you put in zip and his name and contact comes up. Much cheaper than going directly to Schaeffer's.
You may have to order extra as it comes in cases, like I did. But I'll eventually use it all.
But then again....you may already know all that.
I also use their diesel fuel additive. Bought a case that should last forever. No limit on shelf life.

Polarbear, if your rig starts fine when plugged in then your glow plug system isn't working. Do some googling on checking and replacing your glow plug relay.This is true.....
Also do some checking on the top end oil change. It's not a closed system, it's the same oil you see in the pan circulating through the reservoir.
On the interwebz so it must be true......
Ford diesel tech here. If it comforts you, do it. But really, its bs.
The huei injectors on a 7.3 or 6.0 are different animals then the rest, change at 5-7k. You'll hate life when you have a pan full of needle brgs from the cam followers or flushing the wallet for a new hpop.

My '07 Cummins used 12qts and I changed it between 7500 and 10,000 miles.This^.
My '11 Duramax uses 10 qts and I change it by the oil life monitor. Usually approaching 10,000 miles
The Cummins and Duramax are both very easy on engine oil and will run a long time with whatever 15w-40 you want to run.
No rocket science needed.
I change the fuel filter every oil change and on the Dmax change the trans filter every oil change as well.
I don't usually buy into high $ oil hype except for Transynd in Allison transmissions and synthetic in my axles and gear boxes. But that's only so I can go 75k+ mi on the diffs and t case.
Fleetfilter.com has good prices on Wix filters in bulk.
I don't find diesels to be any more difficult or expensive for basic maintenance really.
There are other attributes of a diesel that can get real spendy compared to gassers, especially the post 08s and emissions issues.

Duramax, 10 qts of Amsoil. I change the filter every 6-7k and all the oil at 12-14k
Ditto on this.... 01 has 210000 mi . Been on amsoil since 10000 mi. Love the truck..

I have a 2012 F450 6.7. I use AMsoil in it. Change it every 20K. I put Amsoil in the transmission also. Pulling my boat is a 38,000 lb load. Transmission only heats up 2-5 degrees. 10 Tons of hay and a 7500 lb trailer in the summer, Excelerating up white pass ,no heating up of the transmission and only about 10-15 degrees in the engine. If I had it to do over again I would have used Amsoil in my 99. But I am not unhappy with 400k on the engine. It runs as strong as the day I bought it. I made a New Mexico Trip in November. 35 hours each way. 75 MPH did not burn adrop of oil. At 400K it is still amazing.
