Quick Tranny Oil Question

[leeave96 487]

I believe the manual for my Wheelhorse calls for 90w gear oil, but I'm also thinking older Wheelhorse's called for 90w-140 gear oil.  This is for an 8 speed.

 

I've got 2 quarts of 85w-140 oil in my basement.  I drained the oil and it had a little moisture in it and thought I'd run the 85w-140 oil in in and then drain after a mowing with the 80w-90 oil I also have.  Or should I do the reverse or neither?  Both are GL-5 compatible.

 

The tractor is a 314-8

 

Thanks!

Bill

You will be OK with the 85W-140...but I would run the 80w90 in winter.  I believe the manual calls for 90w.
