Oils & Fluids – “Thread of the Week”!

Well, I thought we were due for our "Oil & Fluids – Thread of the Week"….

So, maybe it’s been answered and I missed it (and where do you start with so many "Which Oil" threads)…. but my thoughts, concerns and questions are in regards to the alternate fluids people are using in both their Front Differential / Hilliard Clutch -and- the Rear Differential / Transmission Combo’s.

Now I know TXRonnie has many documented miles on multiple machines… of using the following:

– "Mobil1 Synthetic Motor Oil 5W20" in the Rear Differential / Transmission Combo

– "Mobil1 Synthetic Standard ATF Fluid" in the Front Differential / Hilliard Clutch

Now I also know Ronnie lives in a region (Texas) that doesn’t see the extreme cold temperatures (or at least for an extended period) and their "cold days" feel more like "shorts weather" to those in the upper Midwest and Canada But my question is this…. Has anyone in a "Northern Climate" region used these fluids in either of these systems with the same success that others in warmer regions have???

I recently reported that I swapped my 2005 & 2012 Sportsman’s over to these fluids, which I have…. but now am second guessing my choice with the concern questioned above. So if other colder regions have also used these same or similar flavors in their machines, please post your successes or issues!!

THANKS!
