I have changed the engine oil and oil filter for my 03/ISL 400 engine several times. For all the good reasons, I always had a friend keeping me company. For the life of me, I don't recall if I pre-fill the oil filter or not? Should we or not?
Early this year, I purchased a used 2018 RAM 2500 Cummins with about 25,000 miles on it, and since then, I've put about 4,000 miles on it. I purchased it from a reputable dealer, but I still would like to change the oil and fuel filters to have my own fresh start. The engine oil indicates 60% life. I have watched several videos on how to change oil on a 2018 RAM Cummins and noticed that some do pre-fill, while some don't. The oil filter is located in a very tight place (it is a poorly designed location). What do you all think... pre-fill or not pre-fill?
I think it is always a good idea to pre-fill an oil filter.
I've never pre filled my oil filters, but it is necessary for fuel filters.
NO. Unless you only pour oil in the outer holes (inlets), not large center hole (exit) you are putting unfiltered oil directly into the engine.
We had a petroleum engineer in the Diesel RV Club. When the question came up in one of the maintenance seminars, he was emphatic that one should not count on zero contaminants in the oil.
It takes less than 3 seconds from start up to fill the oil filter and get full oil pressure.
If you feel you have to pre-fill, only do so in the outer holes.
Totally agree....! no prefill unless thru filter first.
I find it hard to believe that engine oil manufacturers do not put clean oil into clean containers.
My head hurts!
Pre fill don't prefill, I believe more foreign material gets in the oil filter from not cleaning the filter housing before trying to install the filter. Than comes from the new unopened oil containers. JMHO
On my 2006 Dodge the oil filter is buried up under the front side of the engine. I should drain the filter for removal but seldom do. It makes a mess every single time I change it. I cant imagine filling it prior to installing. Double the mess. So Ive never prefilled it. I did go buy the special filter socket for the dodge and use a 12" 3/8 extension to facilitate remove and reinstall. Two other points. I use Dow Corning DC4 silicon lube on the gasket for much easier removal and my dodge front drive line requires being Lubed at oil change intervals. Much better to lube it before oil change mess. Nobody ever greases them. Required at 5K. The first time I do it I literally mark the location with paint marker because it is so difficult to find. Clean the factory grease/paint off of it and then it's easier to find next time. Big red arrow from paint marker helps. PITA.
Stated this analogy before,on some Cat engines if you don't fill the filter then upon startup the valve train clatters like a banshee
for a few seconds,next time one of you non-fillers changes oil have someone start the engine and you stand next to it,don't know
if yours will clatter but would be interesting to know.
On my sidekick I don't prefill the filter as it goes on sideways but the engine is noisy for
a few seconds. On my M11 I don't have to prefill as I installed a preluber so I have oil
pressure before turning the engine over.
Lifting a pre-filled ISM filter into position would be no small task... not worth the frustration IMO since it's been proven time and time again to be unnecessary .
Just asken but how has it been proven time and again,Old guy just said his sidekick is noisey for a few seconds,that is not helping
the engine.
If you change the filters before the oil , the low pressure time is reduced. Then change the oil.
My Cat filters must hold about 4 qts. I fill them maybe 2/3 full and boost them up .
I serviced many turbo cars. The oil change process included turning the engine over with the ignition off to build pressure before the engine runs.
I'm just referring to ISM owners I know that don't prefill (myself being one of them) and I've never heard of a single problem
Old Guy,what kind of prelube system do you have?
I don't bother prefilling the oil filters on most of my engines because many of them the filters are sideways. When it comes to the ISM it's so easy to do I think some people are really exaggerating the difficulty.
The only reason I have not to like my Onan generator is the sideways mounted oil filter, I always fill my filters prior to installation. With the extreme compression and load on the crank etc of a diesel I want oil volume asap not a couple of seconds while the filter gets filled.
IMHO
Back in my trucking days when I paid to have the oil changed in 14+ liter diesels they always prefilled the oil filters, I never had to ask.
I follow the same practice with the coach and my diesel pickup. Yes it takes a little more time and effort but worth it in my opinion.
Drifting all over the place. The original question was
2018 RAM Cummins and noticed that some do pre-fill, while some don't. The oil filter is located in a very tight place (it is a poorly designed location). What do you all think... pre-fill or not pre-fill?
no I don't refill and have done over sixty oil changes over many years on two 2006 5.9 Cummins
I have tried Google to search for an old Texaco commercial with a car using Havoline oil being drained completely then driven around Indianapolis speedway 1 lap the tearing down the engine and showing no damage.
Think I saw that one 40 years ago,the guy pre-filled the filter.
Old Guy,what kind of prelube system do you have?
It is one I made. I bought a pump (which one day I will upgrade) and a check valve a some fittings.
To operate I use a spring loaded switch and I hold it until I have oil pressure and a bit more and
then I start the engine.
Amsoil used to sell a kit but discontinued years ago,not sure why.
No on prefill, What would be the need? What good would it do? None to both questions.
Oil filtering is by-pass filtering. Only a small amount of oil is filtered at one time. Most of the oil goes from pump straight to the parts. If all of the oil from pump went thru the filter, many parts of the engine would be straved for oil and would be damaged. If the filter is blocked, the engine would lock up from lack of oiling. The oil must be pumped thru the oil filter, until the oil pump picks up the oil in the pan, no oil moves any where in the engine.
Depends on the engine,they are all not piped the same,depends on the size of the filter,the filters themselves have a bypass spring,
have changed oil on many engines and all it takes is one time to hear the dry clattering of the valve train to see what I mean.The
engine is not going to fail from one non fill start but it will get more wear,most wear on an engine comes from startup so anything
I can do to eliminate wear helps,it's been said on the forum that these are "million mile engines"well why don't they all last a million
miles,premature wear is one culprit.
That is the very old filtering system. The current ones including our coaches is full flow filtering. There is a relief valve that opens incase the filter completely blocks the flow.
All you need is an accumulator with a diaphragm and a solenoid to build one. Open the solenoid before starting and close after engine is running. The same oil galley port will fill and charge the system. Somewhat similar to the old air starters.
So, now, reading all this and some other reserch on the internet; if I am replacing oil at 50-60% life (and oil looks dirty) why change the oil filter, just change oil now and change oil and oil filter next year. My oil change intervals will be based on time for this truck not so much milage, it will be less than 12K miles for the next year or so. I know ... filter is cheap and just twist it off and put new one on and sleep easy :-)
The LF3000 or LF9009 are both full flow and by bass built into one filter. I just learned something
new as I thought the were just full flow as most filters are. I run my prelube through the filter as
I want all the oil filtered. The reason for the prelube is that engine gets the most wear during startup.
Peter those are obsolete filters for the ISM. Cummins recommends FLEETGUARD LF14001NN. There is another filter that has a lower service life so I just went with the better one of the two. Take your serial number and go to the cummins web sight to verify. There is a service bulletin that covers and Im pretty sure we talked about this before. The reasoning for the post shutdown lubrication was to lube and cool the turbocharger. FOA sells an oil accumulator with a solenoid. But I think it has to be charged after use causing lower oil pressure during that moment of charging.

Oil filter (https://www.foreforums.com/index.php?topic=43662.msg440156#msg440156)
Link is no longer working to filter
So i contacted Cummins and this is the information they sent me for me 2001 ISM450
Scott,
Thank you for contacting Cummins. The resolution to your inquiry, ISM oil filter, is as follows: You can use the LF14000NN or the LF14001NN which is the upgrade.
LF14001NN vs LF14000NN
what's the difference between the LF14001NN and the LF14000NN?
Both filters are 2 stage filters using Stratapore media for stage 1 and Nano Net Media for stage 2. Both have equivalent micron ratings. The LF14001NN is just the extended service option of the LF14000NN, simply put, theoretically speaking you are going to get a little more life out of the LF14001NN depending on the quality of the oil used. If you are like a lot of owners you may be well under Cummins recommended service interval. In that case you can't go wrong with either of these filters. If you need to get a little more life out of your filter and make ever mile count. then the LF14001NN may be your best bet.
Thanks Scott, I will check it out.
I doubt it will burst into flames. Chuck had found a link and currently they are $75 each
Pretty good price on Amazon....

Have rebuilt hundreds of industrial engine turbos and 99% of them failed due to oil starvation,the oil passages coked up with
overheated oil,most large industrial engines have a post lube just for the turbo.
Propman,where are you getting the 50-60% from?
:-)
Engine computer indicates 58% oil life, so oil change is not due for sometime. However oil maybe a year old. I usually change oil every 12-15 months, do it before if we drove and put miles.
Actually they are not on Amazon LFN14001NN yes the 14000 is. I even asked the seller to sell the 14001
John he is asking about a 2018 Dodge Cummins ISB. The computer generates reccomended oil change interval. Non dinosaur.
I was getting my oil filters from NAPA until they got so high priced. They told me I could
get a better price by getting 6 filters. I said no. I went done to my local farm implement dealer
and they stock the Fleet Guard filters. There were almost half the price from NAPA store.
