[AT] Need help with newer compact tractor

Cecil,  Warren Petroleum is based in Dunn, North Carolina (or were anyway).
About 30 years ago when they were a much smaller company
I had the transmission fluid changed in a Chevy pickup. When I
went to pick the truck up he was just finishing and I saw the empty
oil jugs on the bench.  They were the wrong oil.  I forget which one
but not Dexron.  I got on the guy and he swore there was no difference.
I knew he was wrong, or lying, and took the truck to another shop and
had the fluid changed again. But, just to prove to myself that I was right
I called Warren Oil.  I told you all of that to tell you this.

When I called they actually put Mr. Warren on the phone.  I've never been 
more
impressed by someone I called on the phone.  He took the time to tell me in
great detail all about the different grades of ATF and went on to tell me 
about his
company.  They are a re-processor of used oil but unless they have changed 
they
do so with great care and attention to quality.  I have no problem with 
anything they
make.

I say they are a re-processor.  That was a long time ago and
I don't know if they have "graduated" into manufacture from raw materials or 
not.

Mike:
I wrestle with the oil price thing every day with so many engines and
systems I have here, and the lack of funds.   I really don't think that
one can know enough about the  oil he uses.   I have found  a good motor
oil ( Ranch Pro bottled by Warren Petroleum ) at the local farm store
and it has proven to be better than Mystic that I used for many years.
I really do not trust Mystic products like I once did.  They just do not
seem to be as good since Total bought them..  I also do use any
hydraulic oil additive in my Hydrostatic drives.   I was severely
admonished for it by the hydrostat rebuilder when I talked to them....
