Using Non-JASO MA2 Oil

[HISUN Sector 750 EPS Failu]

It looks bad, but the HISUN (Axis) 500 at work has had "regular" oil in it for 900 hours now.  I discovered it when I googled what my Sector 750 uses, it being about time for the first oil change.  This is the only side by side that the mechanic at work takes care of, and he's the type of person who knows it all.  He would never check an owners manual or search something online. 

The problem with someone who knows it all is all you get is what he knows.  

Being on a first-name basis with the HISUN Tech Team, I've asked them what the consequences might be.  I'm concerned that the clutch may be permanently damaged.

Anyone had this experience?

I'm looking for what is the best course of action at this point.  Granted, draining and replacing the oil with JASO MA2 is the first step.

But, is the clutch damage irreversible?

I've watched a video of what the clutch plates probably look like, and what the repair entails.

I have suggested switching to JASO-MA2 oil and new filter twice,  once to purge the bad additives and the second to keep using the right oil, and hope that we can keep using the UTV, even with the slipping clutch, since everyone using it is used to it.

Actually, everyone but me is clueless to there being an issue.  But, then, I have a Sector 750, so am more familiar with how it should operate.

Second option is to replace the clutch, if Option 1 does not work.

I'm guessing using the wrong oil is not uncommon for UTVs bought at Lowes and Home Depot and farm supply stores.

I know a couple people who ,know it all, and used full synthdtic automotive oil and the clutch failed in a short while.One guy put STP additive in his and it went in the same day.

That pretty much applies to the one I'm referring to.  This clutch is slipping, but still grabbing.

It's a machine that's used every day in golf course maintenance.  I don't believe they've gotten around to switching out to JASO MA2.

Change oil , run a few days and change it again is what I would try..oil is cheap, changing clutches is not

That's exactly what i recommended.  Like I said, those using it are used to the clutch slipping (they are clueless), so hopefully it won't get worse if we switch oil, twice.

When a new clutch it is supposed to be soaked in the correct oil for 24 hours. So maybe changing to the correct oil and a few oil changes will prolong the life of the clutch. But I will probably need to be changed in the near future.

 

When changing the oil. Disconnect the hose at the top of the radiator that goes into the oil cooler. Do not use an air compressor. Just use your lungs and blow the oil out of the cooler back into the engine. Then hook up the hose back to the tube and unhook from cooler. To blow the oil out of the tube. You'll get most of the bad oil out that way. If you do use an air compressor be careful and remember I told you not to use the air compressor.

 

Good luck.
