Trans Gear Oil or Trans Fluid?


Recommended Posts

Pretty sure I have this one correct but since we have this great resource I am going to use it. The Owner's Manual says to use 90wt gear oil. I assume this is the same gear oil as the diff. I am going to use/change out to Royal Purple Max-Gear Sae 75W-90W also good for Limited Slip. Reason I am asking is because my last race car used Trans Fluid and it was also an Asian Manual Trans. The little bit of leakage when I changed out the driveline was gear oil not trans fluid. Anyone see it differently or have any concerns? OR what did you use?

If your going to use Royal Purple I've noticed Jeff from No Limits uses R.P Synthetic 75w140 Gear Lube http://shop.nolimitspowersports.com/produc...mp;productId=86 but from what I see both are good so the choice is yours. I had a look on Royal Purples website & in their pdf info sheet http://www.royalpurple.com/prod-pdfs/max-gear-ps.pdf it states that meets warranty requirements. Max-Gear meets or exceeds OEM warranty requirements for GL-5 automotive rear axle hypoid gear lubrication & is compatible with other oils. Max-Gear is compatible with other mineral gears oils and other synthetic hydrocarbon gear oils.

Go for it as rocmoc, I will next time too but read the pdf info 1st just for peace of mind.

Cheers Mike

      I have a 2022 500 Hisun product, I have had them in the past. I change my oil myself and trying to drain through the hole where I remove the plug is a mess.  How does everyone keep the belly pan clean during the oil and filter service?

      Please help I have a Massimo 400 buck that has an oil leak. The oil is leaking on the front side of the motor. It leaks out of a u-shaped steel pipe that has two banjo style fittings on it. I have tried using RTV and different banjo washers and have had no luck. It drips about one drip per second while it's running. I can't find parts for it at this time.

      We own a 2020 Kubota RTV-XG-850, with only 400 hours on it and it has been at the dealer 3+ months. We were just informed our engine failed and requires a complete rebuild at only 400 hours! There is a loss of compression in cylinder #1, which is causing backfiring and a loss of power. There is also excess gas in the engine oil. 
      We are just outside of the manufacture's warranty period, and they are serving us a nearly $5000 repair bill, with only a 90 day warranty.

      A member at a different forum had the same issue at 22 hours and fortunately, his RTV is under warranty. He was informed that "short tripping" (as Kubota describes it) causes gasoline to enter into the engine oil, which causes a dilution of engine oil and eventually leads to catastrophic engine failure. This killed our engine in under 400 hours!

      Is anyone else with a 2018-2022 XG-850 running into similar issues?
