aw 32 oil, brands
- Thread starter opus
- Start date
For starters it most likely doesn't take just aw32. Most likely shared fluid with the transmission. Depending on the model you will need John Deere HyGuard or the low viscosity version.
How many hours on the meter?
I went with ExxonMobil for my tow truck after some research. Not sure why exactly.
Yes, it does share, so that answered that part of the question.
Under 2000 I believe.
Yeah, 2000 hours is probably double what JD wants for the service interval.
Yes, and there is a difference in specs. Citgo and hydraulic oil retailers now know this, too.
Hornbeck, et al. v. Tractor Supply Company, et al., Case Number 4:18-cv-523-NKL (Western District, Mo.)
A 2018, $18+million settlement against Citgo and a number of retailers for selling oil they claimed met JD 303 specs and labeling it as universal hydraulic oil. However, around 1974, JD made significant revisions in its hyd oil specs. Around 2017/ 2018, the Missouri Dept of Ag tested a number of hyd oils and concluded many of the private branded "303" hyd oils were wholly deficient and nothing like a "universal" hyd oil, and were causing significant damage.
I have looked at the Universal Hydraulic Oils in Sam's Club, Walmart and TSC but have been frustrated when trying to nail down their specs and simple stuff like viscosity. Some equipment calls for friction additives, others don't. Some super spec oils may be able to span the specs of several of the OEM fluids in the same equipment, simplifying maintenance, but this is not always clear.
Caterpillar offers significantly longer warranties on selected equipment if using its TDTO oils, and it claims something like 5 to 7% less power needed for produce the same net work in its excavators, and lower temperature.
Here are some notes I have gathered that may be of interest. Please correct/ advise to delete/ expand as needed.

A note on use of TDTO & alternatives:
"just found a suitable sub for TDTO...Castrol makes a 'Trans-C HT' for powershift transmissions...
Shell has a 'Donax TC' for powershift as well.Both have the additives at the TDTO spec..thanks 2 all...

bunkclimber, 09-10-2010,: well, there's two kinds of TDTO in Castrol land, a standard petro 'Trans-C' and a synthetic 'Trans C-HT'..the petro Trans C is 53.00USD/5gal and the HT version is closer to the 97.00 mark like the Cat TDTO product. I talked to the guy that blends the lubes for Castrol here in MD and he said the HT is a synthetic blend..much more $$ over the petro standard Trans C product. It features extended service intervals..personally running a 977 farm machine,the petro Trans C should do Ok..
Adding some wings to your JD? Here is some info on aircraft hyd fluids. Don't forget these have to flow at very low temps. These would likely cause problems in terrestial equip.
FWIW Shell Aeroshell Fluid 51 lists as meeting MIL-PRF-87257 specs, and is dyed red, syn hydrocarbon & ester based, -54 => 135C, exceeds mineral-based fluids of MIL-PRF-5606, is compatible w MIL-PRF-5606, MIL-PRF-6083, MIL-PRF-83282, MIL-PRF-46170, AeroShell Fluid 4, 31, 41, 61, & 71. MIL-PRF-87257B equiv to NATO code H-538 and Joint Service Designation OX-538. Radco Ind Radcolube FR257 should be equiv & lists NSN 9150-01-388-7769 (qt), 9150-01-386-6687 (gal), 9150-01-391-2087 (5 gal), & 9150-01-387-4577 (55 gal drm) as equiv.
