Well pretty much like every other 500 to 800hr oil filter off a Kubota diesel flood light.
Napa gold 1334 with 990hrs on Kubota diesel
- Thread starter oil pan 4
- Start date
What is the factory OCI? I’m guessing it has the D1005?
I was on a job site one time where a concrete company ran one for ~6 weeks straight to run a pump.

I'm curious if the filter has any indication that it went into bypass? How does the loading look in the media?
Did the oil get changed during the filter interval, of was it also at 990 hours?

I wish I knew if it went into bypass.
As far as I can tell it didn't get changed.
The customers don't have any reason to change oil.
The oil was full and there's an oil leak so they at least added oil.
It's gone. There really wasn't anything inside pleats, a tiny bit of sludge is my guess and I had to hunt for it.
An oil filter is to catch the chunks that go thru the suction but if its full of stuff something went wrong or someone teaspooned dirt in to it. I kept a sample, havnt splurged for the test yet of an LP gasser we ran 15 years and some yrs a couple hundred hrs and even put a couple gallon used oil in it.
I just looked at one of our old diesels, 8 yrs and prolly in the 800 to 100 hr range but mostly clean work. Had another one in for a leak and got the eng oil changed and its about the same, 10 yrs and in that range for hours and running T4 which is wayyyyyyyyyyyyyyy better than when these engines were built in the late 60's, one mid 70s. Very little/no winter work though.

I put T6 in one and want to see if the starting is noticeable.
Running a floodlight is got to be as decent duty as it gets, likely clean air, consistent temp and long run, 900 or 100 hrs prolly not a big deal.
I had one on a welder genset we were moving and made some sense to service due to convenience. I pull the dipstick on a little air cooled gasser and can see thru it but I looked at the notes, 415 hrs. We were done with it at that point and I felt guilty so I changed it. Ran it 10 hrs in 10 yrs since.

While I get the science on new equipment what is so neat to me is the use of modern oil in old engines. We are now changing at our convenience and running 10 times the oci as when they were new and really cant tell any difference and done have the sludge would have been found in them back in the day, that was common and now never unless there is a real fault. Even old dirty oil is simply dirty.
Right before I started working there they had a Cummins 5.9 that was running very poorly. When they went to change the oil they had to poke a wire into the oil drain hole to get oil to drain. That engine got changed. Don't know the hours on the oil.
