SUDT2 is synthetic, and Kubota markets it as superior to UDT in cold weather as well as performance under high temp conditions.
The 2 types are fully compatible. Short of performing lab tests I don’t know how to tell the difference.

From what I have read the above seems accurate. The SUDT2 has been said by some to make the equipment run quieter.

If you got it from a dealer, Very unlikely they put SUDT2 in a B21.

Thanks . Glad to know they are compatible . That was biggest concern .
