EASY! Cummins 6.7 2013 and up oil change

[SnoKing]

Did you put the full 12Qts in? If so check your oil if it has been sitting for several hours. Are you about an 1/8" or so over full?

About a quarter inch over!

YUP, that's why I only add about 11 5/8 quarts even after letting it drain overnight.

See by doing so I will eventually have enough "SAVED" oil for a complete free oil change.

I am still using the FleetGuard filters from a one case purchase a while back.

Understand you may have some LF3894 filters from a prior purchase and are using them up. Will you shift to Fleetguard Stratapore 16035 when the time comes?

Best funnel available! When it is screwed in, it will not tip over or spill over. SNOKING

I don't know since I use big pliers at the top of the filter to remove it. The 16035 has the bottom filter flutes and the 3894 does not. They are the exact same filter and the same price at Genos right now. so I will buy the less expensive one when I run out the the 3894's.

My nylon web strap wrench works well after the first gorilla installed filter finally breaks loose.

Thanks Cummins12V98 for the feedback and good to know. I had seen both on Genos but didn't realize they have the same innards. The indications on Geno's is the 3894's are for an older application.

Having the ability of working at a machine shop, I made a aluminum cap that screws into my filter and seals so you can take out your old filter, and prefill your new, all through the fender.

I should have patented the damn thing, because I see genos has come up with the same similar thing a year later, damn it. o well, it works very well.

Don't Pre-fill your oil filter!

I'm surprised that no one here has yet commented that you should NOT fill your oil filter when you change your oil.

Several years ago these forums had a story, which has been confirmed true by TDR, about an engine that was destroyed by a tiny piece of aluminum that was poured into the CLEAN side of the filter by a well-meaning owner. When the engine was started, that piece worked its way to a small oil passage and plugged it, preventing oil from reaching a critical part. The engine was destroyed and neither Dodge nor Cummins would repair it under warranty.

Okay, I guess with today's bottles that (mostly) no longer use aluminum seals a careful owner could pre-fill the oil filter, but always remember that you are filling both the dirty and the clean side of that filter. Oil that you add to the sump via the oil filler goes through the filter before it gets to the engine. Some of the oil inside the filter doesn't.

Sorry, I am not willing to take the time to find that old anecdote, but I wanted to remind members about the hazard.

I've heard of these stories myself, but I still pre-fill it. Like you said, most oil containers don't have the aluminum anymore. I'm sitting right next to my 3 1 gallon jugs of Rotella and they have the nice caps which break away from the plastic cleanly.

Curling up with a nice jug of oil for the evening?

I've owned RAM / Cummins powered pickups since 1997 and have never had a problem with pre-filling the oil filter. I will continue to do so....not only on my RAM pickup, but any other vehicle I own that the location of the oil filter will allow me to do so.

For those that are inclined NOT to do so, pre-filling is probably not a necessity any way, as I'm sure none of the lube*monkeys take the time to pre-fill an oil filter on anything, whether at the dealership level or an instant oil change place.

If one has extreme paranoia :-laf about pre-filling, get a section of correctly threaded pipe, screw into the filter, and fill utilizing the outer most holes.

HA. Yup, then decided it was too cold to crawl under there on my back so they're still sitting there. In the summer I complain it's too hot, in the winter I complain it's too cold.

Been pre filling filters for 40 years with no ill effect, just be careful.

On the '13 and up 6.7s, is it possible to get to the filter from under the bottom of the truck and come out with it that way? I do this on my '05 and I have no issues. Works well and I don't have to remove anything.

I just turned 40 two days ago so I've obviously not been doing it this long... but have been doing it for around 14 years (since getting my first Cummins) without ill-effects.

Nope, there's stuff in the way.

While it is a bit more difficult to change than on other vehicles, I don't find it to be that big of a deal, especially since I only do it twice a year.

I finally did my oil change. I went the route of taking the passenger side wheel off (decided to do a rotation at the same time). With that wheel off, you can get your body in there enough to get to the oil filter through the access hole in the inner wheel fender plastic. I have two types of filter wrenches. The one that cups the bottom of the filter and you use a 3/8 ratchet on, and the kind that's like pliers that grab on to it. The first filter wrench I could get in there, but couldn't get enough leverage on it to be effective. I then went to the plier type, and got it off with that. Took me several tries as I could only turn it probably 1/4" or less at a time, but after several tiny turns I was able to get a hand in there.

Used the freezer bag method of catching the nasty oil filter, as I've been doing for many years with my prior CTD. As for prefilling the oil filter, like I've been doing for years I just filled it halfway this time. Reason being, you have to tilt the filter completely horizontal to get it back in via the fender-well, Therefore I put just enough oil in where I could tilt it on it's side without leaking everywhere. Genos has an aluminum screw on "lid" for the oil filter to temporarily make it spill proof until you get it in there. Filling the filter half way gave me enough peace of mind though.

Other than that, the process was uneventful. I used a Fleetguard filter, and filled it with Rotella 5w40. Oil pressure came up immediately, just like it does any other time I start it up.

Seems like I could put a bit more than the 12 quarts in there as it's only just barely in the safe zone on the dipstick. I haven't driven it, but it is on a slight hill so once I get it in the street I'll check the level again. I did put my electronic level on my running board and my truck is only at a 3.2% *** low position, but I'll get it in the street and see if the oil level gets to at least the halfway point in the "safe" area of the dipstick. I'm so damn ADHD about my oil level, I sometimes make myself insane.
