I typed up about a three page reply to this general topic - throughout the day I typed a little more.......
then after all that I typed, I said f' it - aint gonna make any difference at all - like politics, or gun control - people have their mind made up, and little else will change it!
I will say this, most if not 95% of the time the acronym UDT is used.....this is a 40+ old oil make up that many companies have copied to the letter.
If you have an older machine, one that called for UDT, then run it or anything that meets those specs and it will be terrific!
What really burns my ass however, are those out there, buying a
new machine, and NOW wanting to place an older type oil in it, or another brand of oil in it that will "work" cause grandpa did it 40 years ago......
The older machines worked fine on UDT, sub it out by all means.....it will be fine.......
but IF the newer machines use an OIL better than UDT (S-UDT2), why in the hell would you want to go BACK to an outdated oil?????
and yes - there are many still out there, running straight 30 weight in their 1948 8n's!!!!! Why, cause that's what grandapa did and it worked well!
Next one that wants to use a "different type of brand of oil" - show me the specs....all of them - and tell me that it meets Kubota S-udt2 standards......and I will wait in line with you to get it!
otherwise
who said it? I fool and their money are soon separated!
