Some motor oils have a GL-4 spec .
On second thought, Sae 50 . Every decent vendor carries Shell Rotella T1 or an obtain it.

Universal tractor fluid is a 5 w 40 weight oil. Walmart has it.

Viscosity is a simple rheological measurement

UTF is BOTH a SAE grade 80 gear oil and a SAE grade 30 engine oil.

Correct

UTF is also a mid EP gear oil AND a AW hydraulic oil that is yellow metal safe for use in transmissions (esp hydrostatic), hydraulic pumps, and final drives.

Here's another option..I think

SuperTech Gear Oil SAE 80W-90 GL-5 18.9L Pail - Walmart.ca https://share.google/Oo66f1xBiZcm9Q9R2

No i just see GL5..cant use it

Okay, thanks! I am going with the 15w40. The rear wheels were leaking and I think it is because they were too full.

If you can determine Walmart product is yellow metal safe you are good to go. Look at the MSDS sheet .

 

[Duner Wi]

Correct

UTF can be 30and 80 but not all UTF is 30 and 80. Read the supporting documation carefully.

Find me one that isnt. I have read hundreds of product data sheets. KV100 for UTTF varies by product but is typically somewhere in the range 9.0 to 10.5 cSt with the vast majority clocking in around 9.5 to 9.6 cSt

SAE VISCOSITY GRADE SPECIFICATIONS

SAE 30 - 9.3 to <12.5 cSt @ 100C (J300)
SAE 80 - 7.0 to <11.0 cSt @ 100C (J306)

All UTF is "multigrade" although I have never seen an actual CCS or rotary viscometer test result for one..The xxW nummbers are basically made up.

All multigrade means in this sense is these products have a viscosity index starting around 135 and specialty low viscosity formukations like John Deere Hygard lo-vis and Kubita SUDT2 have VI's around 200

That has nothing to do with with the SAE 30/SAE 80 specifications.Dan

 

[Duner Wi]

All UTF is multigrade.

Good to know, I remember back in the olden days when some UTF was SAE30 or close to it. You had to purchase the higher priced good stuff to get SAE15 or thereabouts.

You are confused by how the grading system works and what the grade numbers mean. They are names not units of measurement.

Look up SAE J300 and SAE J306 for how the grades are defined and measured.
