Which hydraulic fluid to use

There is no longer any FORD M2C-134D spec hydraulic oil made -CNH sells a synthetic stuff made for the newer Boomer models. The discussion is ongoing as to what to use. Search the archives here to find any post that talks about the subject and get all the opinions and advice that has been offered up til now. A UTF will work fine. Many use the same SAE-90 API GL-1 oil like what NAPA sells and should be fine in any climate. TSC sells the same thing for a few dollars less......(hhhmmm, is that a Clint Eastwood spaghetti western... GRIN) say "specially formulated for old Ford Tractors 39-64" -really? What's so special? Read, make your own conclusions, it's your tractor, do what you want.

Yes.. it cost a whole lot more.


Question.

Does your tractor need the most expensive synthetic hydraulic oil made?
Do you need to run fully synthetic motor oil in your engine?

Answer... depends... If your running something very new, hydro shift, power shift, automatic, super high pressure hydraulics, then maybe the answer is..... maybe or yes.

If your running a ford 900, 2000, 7710, or 3600, or older, the answer is absolutely not. These tractors NEVER spec'ed those oils.

Many cases the so called "303" spec'ed oil is equal or exceeds the ford spec at that time. AND the 303 oils today are actually better as the base oil has changed to a modern base oil better than the viscosity stable, and oxidation resistant sperm whale oil used on the original 303 oil.

Bottom line if your running a new tractor, you will need the newer synthetic blends due to the excessive heat and shearing of the higher pressures and auto trans. Older tractors dont even come close.

Your tractor, your choice.
 
As somebody else said, it depends. Does your tractor have wet brakes, or wet PTO clutch, or a reverser unit? At LEAST once or twice a year we'd get in a customers machine where they had tried to "save some money" by using incorrect oil and delaminate the friction material off their brake discs, or PTO clutch pack, or reverser unit. Sure burned up all the savings they made on their oil. Oil is way cheaper than hard parts, how much do you need to save on oil to pay for an overhaul on your hydraulic pump, or new power train gears because the film strength on the Low Bid Sid oil caused a failure? You also know that the failure is not going to happen while in the shed for the winter, but right in the middle of planting, or haying, or harvest. And the way it was explained to us at service school is that the the after market oils MAY meet the spec when you pour them in the top, but that the OEM grade oils additive packages are designed to still meet the spec at DRAIN interval.
 

90 weight oil is not suitable for your hydraulics. Further, it depends on what tractor we're talking about here what the original sec might be. for safety's sake I'm one who says find something that meets or exceeds CNH M2C-134D and your bases will be covered. Run - don't walk- away from anything that's labeled 303 fluid!
 
Ford spec M2C-134D is the spec. Walmart HD tractor fluid on sale at WM.com is $40 for 5 gal. Ford never made any fluid and neither does WM.
 
(quoted from post at 18:27:13 08/12/18 ) Ford spec M2C-134D is the spec.

I think Ford never used an M2C-134D spec either. Somebody correct me if I'm wrong here, but I don't believe that spec came about early enough to be called a Ford spec.

Ford never made any fluid and neither does WM.

That is correct. However each of them did/or do commission a fluid or fluids to be made to their specs.

Larry, do we know what tractor he is running? 2n? ts100?

The 303 spec was slightly advanced or equal, over the ford spec at the time it came out due to John Deere having brake deterioration problems, but still safe for wet clutches.

The 303 fluid is not recommended by anyone around here and in my personal experience with an acquaintance has been known to tear up a transmission and deteriorate oil seals to the point where everything about was leaking.

Have it your way, but in my book 303 is good for nothing . . . except maybe slicking up silage truck/wagon box floors.
 

Do we know which tractor he is running? a 2n would be very different.

Yes, I know you run super synthetic in everything. Thats nice.
 

I've ran Rural Kings 303 tractor hydraulic oil in my older -000 series tractors for some time without any known issues.
I am however switching to Rural Kings Cam2 J20-C hydraulic oil and do run it in my 6610. It claims to be for newer tractor oil specs.
