Difference between ESN-M2C134A, B, C and D (2024)

(quoted from post at 08:41:05 08/19/13) Can someone please explain, in simple terms, the difference between these 4 fluid specifications? My Ford 2N calls for ESN-M2C134D. I purchased some Extreme Pure Flow Tractor Hydraulic/Transmission oil from Tractor Supply. It is rated ESN-M2C134B, C. Salesman said that is what everyone is using. Although this is just a work tractor that only sees occasional work, driveway leveling and possibly moving some snow banks in the winter it gets to rest and take it easy. don't want to use it if it's going to harm the tractor or give me operational problems summer or winter. I live in Mid Michigan about 45 miles north of Saginaw.
Thanks,
Bill

I don't know the difference in the A/B/C/D specifications and I have never been able to find any publication describing them. But in my reply to your previous post I gave you the physical characteristics of Xtreme PureFlo and the current Ambra Multi-G 134D fluid sold by CNH. The PureFlo specifications came from the product data sheet published by the manufacturer (Cross Oil) and the M2C134D specifications came from the technical support desk at Viscosity Oil that manufactures the 134D product for CNH.

Unlike the Ford/CNH 134D fluid the PureFlo oil is NOT an all season oil and it is NOT recommended for use when temps are approaching or below 32F. It won't cause any real harm but it won't give you the best performance either - particulalry when the temps get cold enough to make snow!!! If you want a fluid that more closely matches the 134D specification use the Xtreme Heavy Duty traactor transmssion fluid. It is an all season fluid that will work and protect better than the PureFlo fluid in BOTH winter and summer conditions and only costs a few dollars more. Traveler Premium UTF is another brand sold by TSC that also closely matches the properties of Ambra 134D. NAPA, Walmart, Oreilly, etc. all sell similar products under various house brand names.

Bottom line is, for your application IT DOESN'T MATTER.

This AIN'T ROCKET SURGERY!

Those modern oils are used in quarter-of a million-dollar machines with 60 GPM hydraulic systems running upwards towards 3000 PSI.

Your 'lil old "N" will be perfectly happy with WHATEVER brand of UTF you throw at it.

Or, if it is a bit leaky and/or NOT used in bitter cold weather, simply dump a pail of yellow-metal safe 80-90 gear old in it and ALL will be well!

Yes we can often get consumed with the trivia and miss the big picture. But I got $10 that says that even in a low tech N the difference in the two UTF's is immediately obvious when you fire it up to go plow snow on a cold 10F MN morning . I'm sure some (a lot) of???) folks will happily live with the poorer response just to save a few bucks....

At the other end of the temperature spectrum, 134D is too thin to do the job in our Texas heat. I started having leaks and seeps out of every gasket and orifice. I didn't like the performance I was getting either. I switched back to 80/90 and got much better results.
