In regard to the comment - "A few years ago JD dropped the restriction of using only single weight oil in older tractors"
Where did you read that? I suspect that many - if not most people would not know the difference if a certain oil reduced
the life of their engine by - let's say 10%, 20%, etc. I'm speaking of a collector's tractor - not
one being used daily for hard work. Years ago - when I worked for a Deere dealer - we got
hammered if an engine lasted 8000 hours instead of 10,000 - but that's a different situation.
I contacted a friend of mine who is a retired Deere engineer. Asked him a few questions to
refresh my own memory. He retired from Deere in 1994 and worked in engine-design an
testing.
He states that Deere never dropped their recommendation - to avoid - when possible -
polymer-based multi-viscosity oils in any diesel that uses conventional square-sided piston-rings.
All multi-oils use the said polymers except for the synthetics.
The issue is one of polymers burning off and leaving heavy deposits that cause pre-mature
top-ring wear. This problem was eliminated with the use of triangle-shaped Keystone rings in
the top piston-grooves.
This matches information I have from both Deere and Detroit Diesel - my newest bulletin dated
1991. I also know that some rebuild companies for Detroit Diesel 2-strokes will still void the
warranty if a multi-visc. oil is used unless it's synthetic.

At this age, I believed tractor farming was the only way, hot stuff -- and given a chance I probably would have used the tractor, Dad's first, a 1936 Model "A" John Deere, to go bring in the cows! And I think Dad was ready for some automation too. And so it was that we acquired a good, used J. I. Case, wire tie hay baler. In addition to a person to drive th
