Does anyone know the long term affects that 80W90 gear lube can have on cylinders? All my other tractors (I still own a 1954 IH Farmall Super C) used the standard light weight hydraulic oil. Now I use 80W90 (same thing I use in the rear axle of my truck) for my Zetor . But it does have the front end loader. ??? Just wondering.

GL-5 80W90 Oil

Hey Big Orn,
80W90 - this is THICK STICKY stuff!
Although, it is W rated, you are getting away using it in Texas where your ambient temp is high but would imagine that some of our Zetor driving friends in Scandianvia would have problems in Winter with this. I use SUTO (Super Universal Tractor Oil) which has a viscosity of 20W50 or 10W40. I also used this for my power steering (see seperate post) but had problems as it is too viscous.
The hydraulic oil also lubricates the back axle and gearbox. I can't see that it would do any harm to the hydraulic cylinders. However, it will put extra pressure on the hydraulic pump when cold due to its viscosity. "An oil with too high a viscosity may not pump to the proper parts at low temperatures and the film may tear at high rpm".

Here are some info I got from Shell Sweden when I was asking for a good transmission oil to my Zetor 6341 of visk. 80W for the gearbox and hydraulic .
For example Shell Harvella T 10W-30 and Harvella TX 10W-40 are so called STOU-oils wich mean Super Tractor Oil Universal and they are for the engine including turbodiesel, transmissions including wet brakes and hydraulic.
Shell Donax TD 5W-30 wich are the same as 80W and Donax TD 10W-30 same as 85W are UTTO-oils wich are Universal Tractor Transmission Oil and they are for transmissions including wet brakes and hydraulics. NOT FOR ENGINES!!!!
SAE 80W are thinner than SAE 80W-90 so they recommend use what says in the instruction book.
About API GL-4 and GL-5 they say that GL-5 includes more additives and can handle more pressure before the oil "slide away" for example between wheels in any type of gearbox.
GL-5 are mostly used in hypoidgearboxes. The additives in GL-5 can be aggresive to "yellowmetal" for ex. syncronisationrings in gearboxes so they say API GL-4 are often used in traditional gearboxes and API GL-5 are used in front and rear axles but it can be different from point to point.
That was some info from Shell and I used Donax TD 5W-30 in my 6341 an it is working very well.

thanks a lot !!
So 80w is comparable to 10w/30 ?? never knew that...
I will ask the oil salesman when he gets around in his Sprinter Van, and ask.
We use 10w/30 in the trannies and hydro systems, and 15w/40 in the engines.

That was what they told me from Shell Sweden, they also said that when an oil are for ex. 80W you should know it is a transmission oil, I think but Im not sure the transmissionoils start from about 70W or something like that and the oils you can use in engines starts from 0W but it is possible to get the same viskosity in different W:s for different use. I can see if I find the link to Shell, I think they had datasheets in english. I come back if I find something.
Now am I back.
Go to shell.com[/]
browse to your own country and click on "products" and then you can find a lot of different oils.
When I send questions to homepage of Sweden they send me answers very fast, I hope it is the same in other countries.

Just found out about the 80W90. It seems that Zetor puts this lube in at the factory, but tells its vendors in the USA that they can drain them and fill it with Universal Tractor Transmission and Hydraulic Fluid. It states that if you do this you MUST NOT mix the two grades. Why is this? They did not explain why not to mix them. Will it cause damage? The reason I am asking is when my tractor got low I added the 80W90. What if it already had the Universal fluid changed out? Just wondering what ya'll think.
Hi Big Orn,
Probably because the oils of different viscosities are "immiscible" i.e. they will not mix together even as the oil heats up.
However, I don't think that you could do any damage by adding two oils of different viscosities.

I dont think you damage anything, I have not noticed any trouble when I change oiltype and get back "old" oiltype from for ex. external hydraulics on different types of machines.
But maybe there should be one warning, I have heard of people that get problems with wet disc brakes if they get oil wich not are for that type of brakes.
( That problem was on Massey - Ferguson not on Zetor but maybe the problem could be the same)

I once heard that the viscosity number for gear oil was moved upwards simply to avoid confusion with engine oils. I don`t know if this is true, but at least the facts seems to support it:
I have been using Statoil MultiWay 10W-30[/] on my (now dead) David Brown 880.
The pdf file states that this oil has viscosity as 80W when used gear oil. There is also a viscosity chart, for those interested.
As for viscosity, here in Norway you will be troubled finding oil thicker than 15W/40. 10W/30 or 10W/40 are most common, but those in our coldest areas want 5W, or even 0W engine oil during winter.
And the notion that it gets cold in Texas..........everything is relative, I suupose?

Hi All, and interesting thread!
I went through same drama myself today at the local JohnDeer dealership.???
When i got her, the farmer i got her from, said the gearbox was full of WHITE universal farm oil, i just bit my tounge and remained silent as we all know that white oil means h20 mixed in right???
So i played it safe and changed it to 80w90 as the manual says and the JD dealer also recommended that i use it, as its what his info says to use.
$180.00 bucks later the gearbox has new oil and i must say its heaps quieter and the hydraulics work better than ever, so i hope its money well spent?
Cheers Rob

I bought oil from John deere once for my MF135, never again
almost 70 worth. Almost died when he said how much i was paying him!
Next time i got it from MF, same amount of oil, 40.

we get a 60 liter barrel of 10w/30 multifarm for 250 guilders. last year.
Maybe 140 euro fo rthe barrel now ??

my 6341 was shipped with 85W90 gear oil. I changed it to standard Hyd/trans fluid before the first winter. I don't thing it would have done well with the gear oil in minus 0 degrees F.
