Can I use these oils?

I thought maybe OM or edb whould have been able to cross reference these for you but maybe it takes time as they seem to be European equivalents?

Hello,
I contacted my oil seller and told me that the Ambra MultiG 10W30 (advertised for New Holland machinery) http://flcf.onion.it/commonfile/ENG/pdf/2693_stec_ENG.pdf is the same of Arbor MTF 10w30 (for all machines)http://flcf.onion.it/commonfile/ENG/pdf/3657_stec_ENG.pdf.

Both oils are produced by PETRONAS LUBRICANTS and are "U.T.T.O type lubricants".

The Arbor MTF 10w30 has specification Caterpillar TO-2, then also the Ambra MultiG 10w30 is fine for hydraulic system.

For engine oil, he said that the 15w40 is better than SAE30.

You think it's all right?

The 15w/40 is good for the engine and better than the old 30W as stated but don't use a multi-grade in the transmission despite what it says on the can, this oil will break down to being a 10W used in highly loaded needle roller bearings such as are in the power shift transmission. I have seen it used, on the advise of an oil salesman, in a D4H, the transmission failed in 6,000 hrs. We, the dealer, contributed to the repair cost because 10-w30 was mentioned in the ops guide, we couldn't see the oil sales rep for dust and I wanted to show him the Bulletin I had on this very subject. I would not be keen on the multigrade in hydraulics either but they only need 10W anyway.

15w40 ok for engine.
10w-30 not for trasmission
10w-30 why not in hydraulic system? has Caterpillar TO-2 requirements and contains zinc dithiophosphate (I find that it is necessary for Caterpillar hydraulic systems), after all the cold viscosity should be equal to Unigrade 10w.

Multigrade in the hydraulic system?
He did not say, you can not use it. He said "keen" which is like "opinion" as I read it?
If it meets the CAT requirements, I don't see where it would be a problem.
I do respect catsilver's opinion and comments so would too appreciate his feed back on this?

hello,
this oil 10w30 I already have available, my dealer was not interested in selling.

He told me that the oil I have is exactly the same as ARBOR MTF10w30 (same manufacturer), this oil, if you see the .pdf file above has the Caterpillar TO-2 specification.
I did not know this before asking the question.
At this point I think it can be good in the hydraulic system.

Certainly if I had to buy it, I took the 10w, but I would use this 10w30 oil, that do not use much.

What does the Caterpillar TO-2 specification?

TO-2 spec refers to the oil capacity to allow clutches to grip and is a transmission specification, the reason I'm not keen on using multi-grades in hygraulic systems is that the polymers in the oil which give it dual grade can beak down and separate under conditions of extreme pressure and heat, this could happen at the pump vanes and the separated polymers stick in the filter. I don't have evidence of this happening but cheaper more suitable hydraulic oils are available,

catsilver, I wondered if that was the reasoning behind your comment.
I won't dispute that it could happen as it indeed seems plausible in Molecular Theory.
