Kubota engine oil

[Scook222]

Went to the dealership to get everything for the 50 hour service on my L2501. The guy at the parts counter said Kubota changed the oil from 10w30 or 10w40 to Sae30 now. Both are Kubota brand oil. I have been getting the 10w for the m7040 for a few years now and that痴 all the dealer I use to go to had. I don稚 have the manual on the tractor handy and was just wondering in this is a new change.
Thanks,
Stephen.

I think your dealer may be blowing smoke.
With the correct API service rating, generally most multi viscosity ranges are acceptable. A 30 or 40 weight oil with a W(inter) rating of 0,5,10, or 15 is reasonable depending on your location. A true straight 30 viscosity oil is going to be very thick at cooler temps.
Opinions vary, going with what's in your manual is always a safe bet!

Somebody doesn't know his azz from a hole in the ground. Use EXACTLY what your Owner's Manual recommends.

I would run T6 and be done with it..

I run SAE30 in my gas powered rototiller.... not in a diesel tractor.

You need the 10W in there... preferably at least 10W40.

Heck I run 5W20 in my Briggs gas Commercial engine with a Motorcraft filter... been doing that for years!

I just checked the bottles and it is cf-2 for use in older engines (not what Kubota recommends). Supposedly this is all that dealership sells and that is all they had on the shelf. I also asked for super UDT and the had to go in the back to get it because I was like the third customer that has ever asked for it. I just find it odd that the parts counter would tell me this when I had everything written down that the book calls for and I bought the tractor from them.

Need to find a new dealer, like I said T6, or T5 10w-30 IIRC... don't know how cold it gets by you but if its above 32* year round Rotella 15w- 40 would work just fine..

Stop listening to Kubota on what oil to run, they are 25 years behind.. just look here for threads, you will find many people run T6, I do year round..

Like others have said, pay no attention to Kubota. Even the owners manuals are outdated. What the dealer sells you in the Kubota jug, is something your manual tells you not to use, LOL

I run either Shell Rotella T6 or Petro Canada Duron-E synthetics. Only thing you need to look for is you want the one that is labelled CK-4. It is backwards compatible.

Some new emissions motors (that don't apply to our emission motored tractors) call for a new oil category....called F-4. It is not backwards compatible and you don't want this for your tractor.

These will be shown in the little donut symbol on the oil container.

From the Shell Rotella web site, explaining it all:

Scook - the first line on that bottle reads " for older four stroke gasoline engines and two stoke diesel engines". Looks like your dealer is clearing out some old or slow moving stock.

Like others here have stated, there are better options for engine oil. But not for SUDT I think.

If you look at the Kubota site, recommendation above freezing is 10W-30 or 15W-40.

Let me ask, if oil is used that is not on the list of recommended by Kubota ( such as Rotella ) than how may that affect warranty should an issue occur that may not be at all related to oil choice.

Assuming someone at Kubota wanted to push the issue

As long as the oil you use meets the minimum specs by the OEM you are fine. The Magnuson–Moss Warranty Act*means they have to prove damage was due to improper maintnance components. It's quite illegal for a dealer to just blame the oil you used for any damage to a machine unless they can conclusively prove it.

I vote for T6 Rotella 15W40. All my Kubota equipment gets that. And never use anything in the hydro but Super UDT2, that’s great stuff.

If you look at the Kubota site, recommendation above freezing is 10W-30 or 15W-40.

And also 10W-30 below freezing as per Kubota's web-site.

This is the best answer so far in this thread,
Use a name brand oil 10W-30 or 40 summer or 15W-40 in a conventional oil or upgrade
to a synthetic 5W-40 that meets or exceeds the CK-4 spec and you have a premium oil that meets or exceeds your manufactures requirements including warranty requirements.

Spent 30 + working for new car dealers and Ive seen stuff denied that would shock some people, Im leery to use anything but what they suggest.

Magnuson–Moss Warranty Act - Wikipedia

"Warrantors cannot require that only branded parts be used with the product in order to retain the warranty.[7]*This is commonly referred to as the "tie-in sales" provisions[8]*and is frequently mentioned in the context of third-party computer parts, such as memory and hard drives."

There is a big difference between what some unscrupulous dealers/manufacturers try to get away with sometimes & what is legal. I have a friend who was getting jerked around by a dealer. He left a copy of the Magnuson–Moss Warranty Act sitting on the drivers seat next time his truck was in for the issues & magically the dealer stopped jerking him around.

My dealer doesn't stock SUDT2 only UDT. He said that for our climate we dont need the SUDT which he claimed only benefits is for below 0F operation. It rarely gets below 32F here.
It doesn't bother me anyway since after the first oil change, I just use universal hydraulic fluid that meets Kubota and many others requirements (at least according to the info on the cans). So far with 833 hours on my RTV, no issues. I just changed the HST oil for the 3rd time in my RTV 900 and B26 TLB.

So T6 is ok to use in the smaller BX series(mine is 1870)-I have a Jetta diesel and use T6 in that so it'd be a lot easier for me....
