What oil for 2020 cummins? - Merged oil threads

Can’t believe I ever did these trucks without one.

Takes an absolute mess and turns it into a nearly spot free process. Now I just need one of those porous foam-like pads for my drain pan to avoid the tidal wave of death when draining hot oil.

I installed one of these, takes longer to drain the oil but it avoids the “tidal wave”. As a plus it make’s taking an oil sample easy.


Dodge Turbo Diesel 'Finger Touch' Oil Drain Valve

Drain the oil in your '02-'26 Dodge Cummins Diesel with the touch of a finger and avoid messy hot oil on your hands when doing an oil change.

I would personally never install anything in the oil pan that hangs down like an arresting hook. I spend too many miles on roads with sticks and rocks trying to wreak havoc.

That’s a COLD weather oil. Where do you live?

I am off on trails lots there is tons of clearance for my fumoto valve. If something is going to hit that and break it there will be far more carnage on other components

It actually doesn’t hang down that low, I believe it was right at 1 1/2” long including the threaded portion. You have to push up and over to open the ball valve, I just stuck a zip tie around it on the top above the lever for added security. I don’t do any kind of real off-road with my truck so I’m not too worried about that. If I hit something big enough to somehow pop open that little valve, I’d have probably put a big hole in the oil pan and that little valve would be inconsequential.
 
I drive a pavement queen. The most off roading I do is my gravel driveway. Like AH64ID I don’t like the idea of anything sticking down from my oil pan. Road kill and rubber alligators have a way of finding the very point you don’t want them to. I have never used one of the Fumoto valves but if you like them go for it.

Many trucks use that type of valve and the Fumato valve, including trucks off roading in very rough conditions.
I've never heard of or read about any valve being damaged.

I’ve had sticks dent oil pans, that’s not a good place for a valve to hang low. It’s not an issue until it is.

You wouldn’t know until it was too late.
 
My aversion to fumoto is I like the river of oil flowing out. I feel if there is any sludge or debris in the oil pan it will flow out better without the fumoto. I don’t expect any debris in my oil pan but hey it’s how I think. Also the plug screws in above the inside bottom of the pan and holds in the last couple ounces you would drain without it. Once again minor but it’s just me.

I cut four slots into the Fumato stem that goes inside. I've tested this by pulling the Fumato after draining the oil, no additional oil flows out. I wish I had done the same test before cutting the slots. How do you know a Fumato keeps a couple of ounces from draining?

One of the first things I bought when I got the truck. I usually switch front wheels side to side when I service the truck. I put the truck on jack stands and service the filter through the fender well while the tire is off. Easy that way and with the plug it is mess free.

I ordered the No Spill Drain Kit before I did my first oil change. Doesn't stick down far and the short hose directs the flow of oil where it belongs; in the drain pan. Transmission pan sticks down further.IMG_1602.jpg

Oil pans have a nut/threaded bushing in them to receive the oil pan plug. So there is going to be a small amount that does not come out anyway. The difference is going to be minuscule in terms of a complete oil change.

Yea i get that but really the design of it shows to be rugged enough it wont shear off just add to the dent in the pan. Its not for everyone, that being said i also had one on my 4L jeep rock crawler and never had an incident lol

Exactly i have in the past cut out the bung welded on the inside of the pans for the old 12V as the bungs used to leak and weld the new bung on the outside of the pan for the tiny bit of extra oil drainage
 
Call me crazy, but I’m just not really worried about 4oz of oil on the bottom of the pan underneath the bung, when I’m dumping 3 fresh gallons on top of it.

I do agree with the desire to not have anything hanging down beneath the pan, but I mainly just don’t see a need for it. Extending the drain for the fuel filter housings, however, is a different story…
 
Very interesting tread this one. Being in Australia and living in Canberra we have the full spectrum of ambient temp. Just for 2024 we had -8 to 38 DegreesC. During our December/January trip in South Australia the day will start at 23 at 07H00 in the morning and by 11H00 be 45 DegreesC. You wont believe this but been trying from a month before picking up my truck to get a 5W40 CK4/CJ4 API Full Synthetic engine oil and just cant. Been trying every week with all the suppliers Castrol, Fuchs, Shell, Petronas, Pennrite, Liqui Moli, nothing I have to buy online from the US and this is driving me crazy. So for now because of the low temps I am running the Fuchs Titanium Cargo 5W30 CK4 Full Synthetic and when its warmer I will switch to 10W40 and at this stage I am running genuine filters all round.
Not sure if the 5W40 CK4 is a too new oil in demand and not caught up yet or what the reason is but I would love to use a 5W40 all year. Maybe there is another Aussie that has figured it out on here.

Our temps run about the same as yours. It’s 33C right now and that’s considered cooler weather. The -8C you listed is our lowest temperature and when it gets that cold it only lasts a day or 2. I would like to be able to find a synthetic 10-40 for mine but it’s either 5-40 or 15-40 which isn’t allowed. Usually encounter 40C+ during towing season and would like to have the slightly thicker oil which would probably have a little higher HTHS. I think the 10-40 would be fine since it isn’t getting below -18C or 0F.
