oil type for b2301

[Lorduss]

in my manual is specifies non CJ-4 diesel oil
I have gone to every local parts store and found finding a non CJ-4 oil locally to be impossible

the labes on some confuse me a bit as to it being CJ-4 or meeting cj-4 specs

what is safe to use in my tractor?
does CJ-4 really matter?
CK-4 ok?

in 99% of cases the newer oil is backwards compatible so CK is newer than CJ so will suffice.
From API
API CK-4 oils exceed the performance criteria of API CJ-4, CI-4 with CI-4 PLUS, CI-4, and CH-4 and can effectively lubricate engines calling for those API Service Categories. When using CK-4 oil with higher than 15 ppm sulfur fuel, consult the engine manufacturer for service interval recommendations.

CK-4 is fine and as mentioned, backwards compatible to CJ-4 and previous.

But, be careful with universal diesel/gasoline oils being API CK-4/SN. There were some loop-holes eliminated concerning maximum phosphorus ppm's allowed, compared to the older CJ-4/SN classification. I think only CK-4/SN grades 5w-30 and 10w-30 were affected and in my opinion, those do not have enough phosphorus that diesel engines need in adequate anti-wear protection for longevity.

Also, don't use the new API FA-4. That diesel oil is not backwards compatible to any diesel engine built before 2017. Not sure if FA-4 is on the shelves yet (not in my neck of the woods anyway), but will be soon and adding to which diesel oil confusion for consumers.

But the OP is saying his manual specifies NON CJ4 oil? Don,t know how old that model is or why that specification?

2016 b2301, this is its first oil change
Manual specifies non cj-4 oil for non egr machines

I obviously read the original statement incorrectly, you are saying it says DO NOT use a CJ-4 oil? So what specification oil does it say to actually use?

 

[Lorduss]

"The cl-4 engine oil is intended for dpf type engines and cannot be used on this tractor"

Says to use

"Cf, cf-4, cg-4, ch-4, or ci-4"

Leaving me a bit confused because nearly everything in the shelf is cj 4 or blank stating on the back it meets cj-4 specs etc

Funny is it did not state that I could or could not use ck-4/sn

Your gonna be hard pressed finding an engine oil that doesn't at least meet the cj4 rating. The reason being if someone goes into the auto parts store, wally world, tractor supply, ect.... buys some diesel rated engine oil and blows the engine in there $100,000 tractor, someone is gonna hear about it.

Honestly if you call your local dealer, you will probably find they will tell you to use a cj4 rated oil in it. It isn't gonna hurt your engine

Here's some frequently asked questions Specifically numbers 6, 7, and 8 in the link

This is a trickier question than it looks if one focuses on the letter salad in the owner's manual. In the manual for my 2016 b2650 it says something similar. The manual also covers the b3350 which is a dpf tractor. So there is a table that says for the b2650 use cf, cf-4, cg-4, ch-4, or ci-4. For the b3350 it says cj-4.

So I went out to the barn and checked the bottles of oil that I had gotten from the dealers when I got the 2650 and the L3560 which has a dpf. I asked for a quart of whatever was in it for each of them. Each bottle had specs that started with cj-4 but which also had some but not all of the other specified grades. They were not the same, but one was 10 - 30, and the other was 15-40.

So since you have a brand new tractor under warranty, my advice would be to get Kubota oil from your dealer and keep the receipt.

Lorduss is that a typo in your first sentence? Is the cl-4 or cj-4 ?

As I suspected all along.....the oil people make better oil faster than the publishers of the manuals!

I posted all this a long time ago. CJ4 is fine for any Kubota. It is backwards compatible.

And like I stated before right from the mouths of three Kubota reps at a dealer show I spoke to "lots of info in the manuals are incorrect, maybe due to being lost in translation to English. Just as it does not specify to drain your oil at 50 hours. This is wrong." (says the Kubota reps...change filters AND oil.)

And to back that up even more.....buy Kubota brand engine oil. You will notice it is all CJ4.
Just do use API FA-4 oils. You just need to look at the "donut" (round symbol) on all oil jugs. It will tell you what it is.

It looks like Rotella T1 and Valvoline All Fleet Plus aren't CJ-4 but they are straight weight oils. All the other diesel oils those two brands make is CJ-4.

I'd go to the dealer and see what they recommend, at least then you should be covered as far as warranty goes.

Anybody got any idea how the CJ-4 could be bad for a non-dpf engine? If it is then there's not really much of a choice for pre-dpf engines, so I'm thinking it's not harmful to them.

So cj-4 is good to go, what about the ck-4/sn I put in yesterday? Should I drain It or leave it be?

 

[ItBmine]

Why exactly?
Edit: Maybe you left out the "not" , if you did, correct it and I'll delete this. If not, please let me know why.

Yes, sorry.....left out the NOT.

CK-4 is also fine you can leave it in. It is also backwards compatible.

FA-4 is for the latest 2016-18 engines and it may be fine in some older engines but it is not necessary. And it will cost more.

Here is a good explanation from the API.

If it's 5w-30 or 10w-30 and if it were my Kubota, I'd drain it. It's just those two grades under CK-4/SN that are now only allowed <800ppm of phosphorus.
