1/2 full oil filter?

[91W350]

I just changed the oil on my 1993 and the Baldwin filter was only half full. The sticker said it had Royal Purple in it before. It now has Fleetguard and Rotella in it. The oil did not look that bad on the stick, but it is darker black than any oil I have drained out of one of my Cummins before. Engine sounds good and had not been using any oil, hopefully it was not the tar inside that kept the consumption down. Anybody pulled a less than full oil filter before? I normally fill them before I install them. That was some nasty looking stuff! The sticker said it was due about 600 miles ago. It was changed in August, I hope that was not 12,000 or 18,000 or 24,000 or more ago... . Glen

Half-full or half-empty...

Glen, my Fleetguard oil filter is always half-full when I remove it to change the oil. I fill the filter about 7/8 full as it continues to settle as I install it. I change the oil at 4500-miles. I use Mobil Delvac 1300 Super, it works great for my rig . It was recommended by my neighbor who had a '89 CTD at one time, (2nd Gen owner now ). Patrick.

My Fleetguards are always full when I take them off, or very close to it. It was nice to tip the filter to get it below the intake hose and not have iol run out on the inner fender liner. I cannot remember changing the oil on anything with a filter and not having the filter be full. Especially one that is mounted like our Cummins filters are. You would think there would be no way for the oil level to drop below full once filled. So much for thinking, I guess. Thanks for the positive vote though, I was worried about a plugged oil passage or something. I almost fired it with the filter not tight, just to see if it would blow oil out. Glen

Glen,



I used to think that the filter should be full when I pulled it, but got sidetracked one day after I had warmed up the engine. After setting a bit, I took it off and it didn't spill out when I removed it. I thought something was wrong, but realized that it had settled during that waiting period.



As to the spillage, I put a plastic grocery bag around the filter after I have gotten it loose. Even if the oil is hot, it will hold long enough to get it over the drain pan.



When I'm putting clean oil in the new filter, it seems like it could drink it all day. I don't know where that stuff goes in there.

Do you suppose there is any way for that oil to be getting siphoned back out of the filter? I wonder how the oil galleys run in a CTD. Glen

I've never seen mine 1/2 full... but if I let it sit a while before removing the filter it might drain as much as 1/2 inch below the top.



Been using the grocery bag trick (a zip lock bag is better) for many years... being a boater it's necessary to keep oil out of the bilge. Kind of a pia to clean it up from there... . and you can't pump it out... . (a drop of oil in 10 gallons of bilge water makes the water look like the Valdiz has been in town)

Mine is 1/2 full when I change the oil.

It sounds like it will syphon out the filter some:

I always drop the oil, change the TP in the Frantz, then the spin-on. Enough oil is drained back, as to no leak much, if at all, when removing it.

Thanks guys, that makes me fell considerably better about the condition of the engine. Maybe it is on the way to a million mles after all. Glen

Am I missing something here? Was this in English? Not trying to be mean, just don't know what this is.

I think you's guys got it figured out. I drop the oil first and do the filter last. There is generally only 1/2 quart left inside the filter. It pulls it out somehow.



I found this to be true on the fleet of B's as well as my own trucks.



Phil,



You have to use your decoder pen to read the codes here. Apparently your not a decoder pen carrying member.



I think he has a remote mounted fine/by-pass filter or he pops open a cold one and set down in the lawn chair and watches the oil drain out. LOL

That is the order I use when changing the oil. The spin-on filter comes off last. Not much mess.

Phil,

He's saying that he drains the oil, changes the roll of Toilet Paper in his Franz bypass filter, and then changes the spin-on factory oil filter. Doing this in that order enough oil drains out of the spin-on filter that it doesn't leak and make a mess when he removes it. Oo. Oo.
